These chocolate walnut muffins are extremely moist. They have a rich chocolate flavor and pieces of walnuts packed in every bite.
Is there any better partner for chocolate than nuts? I can’t think of any.
When I made my chocolate walnut cookies I thought to myself that chocolate walnut muffins would be really good.
Boy was I right! These are officially my favorite chocolate muffins.
Oh, and did I mention that these muffins are completely dairy free? I think that is actually why they are so good.
Instead of milk, I use black coffee which really brings out the deep chocolate flavor.
I also use oil instead of butter, which makes these chocolate walnut muffins extremely moist.
My favorite part of this recipe (okay almost all my recipes) is the easy clean up.
You don’t need a bowl for dry ingredients, a bowl for wet ingredients, and a mixing bowl.
Just one mixing bowl for everything.
If you haven’t guessed it yet… I hate doing dishes, and if you could do less without sacrificing quality why not?

MUFFINS VS CUPCAKES
You may be surprised to learn that the difference between muffins and cupcakes is actually up for debate. In fact, every time I make muffins, my family argues about what makes a muffin a muffin and a cupcake a cupcake.
I used to think that muffins are very large and much denser than cupcakes, but I’ve also had muffins that weren’t as big or heavy.
So, what makes a muffin a muffin and a cupcake a cupcake? Frosting. Yup, that is the only consistent difference. Cupcakes have frosting and muffins don’t.
I also read that muffins have a quick bread type of batter, whereas cupcakes use cake batter. While this makes sense, I’ve seen all kinds of batters used for cupcakes so I’m not sure I buy it.
HOW TO MEASURE FLOUR AND OTHER DRY INGREDIENTS
Using a dry measuring cup, scoop ingredients from the bag or spoon them into the cup.
Next, level off the ingredient by removing the excess with an upside-down butter knife.
The one exception to this is brown sugar. Brown sugar should be packed down and then any excess should be scraped off as well.
DRY VS LIQUID MEASURING CUP
Ever wonder why measuring spoons often come with a set of measuring cups? I used to. I didn’t see why we needed a set when we could have one large measuring cup.
After a quick search, I had my answer. I discovered that the large measuring cup is used for liquids, whereas the set is used for dry ingredients.
As it turns out, if you try to measure dry ingredients with a liquid cup, the measurements get messed up.
First, you pour the flour or cocoa in, next you shake it around to get it level, and then you add more.
By shaking it, you are causing the powder to settle, and when you add more, you end up using more than called for.
WHY SIFT FLOUR and Other Powder Ingredients
There are a number of benefits to sifting flour and other ingredients like cocoa ingredients:
It removes any unwanted debris and you can get a more accurate measurement than when packed tightly in a bag.
It also removes any lumps that can get into the batter and be hard to break up later, or be missed altogether before baking.
If you sift the powdered ingredients together, it helps combine them and mix more evenly with other dry ingredients like sugar.
Why use coffee?
Coffee really brings out the chocolate flavor in baked goods. In fact, when I was making my chocolate muffins, their flavor tasted flat until I added coffee to the recipe.
There are two reasons for this: First, coffee helps enrich the chocolate flavor. Second, the heat from the water helps bloom the cocoa.
Do you taste the coffee?
No. The coffee is just enough to really bring out the rich chocolate flavor but not enough to taste like mocha.
How to Make Black Coffee
Usually it is 1 teaspoon of instant coffee per cup of hot water.
Can Children have this since there is coffee in it?
All over the world, children generally do not have coffee because it isn’t good for them. Oddly, they are allowed to have soda drinks and energy drinks which is worse, but that is another topic.
In the case of this recipe, the small amount of coffee as part of a whole cake is not enough to be harmful.
Can I leave the coffee out?
Yes, but it may make the chocolate flavor taste less rich. So, make sure to replace it with hot water so you still bloom the cocoa.
BAKING WITH OIL
In general, oil in baked goods makes for a superior texture than those made with butter.
Oil cakes tend to bake up taller with a better crumb. They also stay moist and tender far longer than recipes made with butter.
Furthermore, since oil is lighter than butter, the texture of oil cakes is lighter too.
Also, given that oil is 100% fat while most American butter is 15% water, it creates a more tender crumb.
This is due to the fact that the extra water strengthens the gluten, resulting in a crumb that’s more dense.
Which Type Of Oil to Use
I use neutral oils like canola oil, safflower oil, and vegetable oil. However, it’s not unheard of for oils with stronger flavors like olive oil or coconut oil to be used.
If using olive oil, I recommend using pure olive oil for its milder flavor and higher smoking point.

WHICH TYPE OF COCOA TO USE
When a recipe calls for cocoa, always use unsweetened cocoa powder, unless specified otherwise.
This allows you to have better control of the sweetness of what you’re making.
There are three basic forms of unsweetened cocoa powder.
NATURAL COCOA POWDER
Natural cocoa powder comes from cocoa beans that are fermented, roasted, processed at a higher heat, and milled into a powder.
It’s bitter, with a very strong and concentrated chocolate flavor.
This cocoa powder is acidic and is often used in recipes calling for baking soda, because the two react with each other to allow your baked good to rise.
This is most commonly used, and should be used, in recipes that simply say “cocoa powder.”
DUTCH-PROCESS COCOA POWDER
Dutch-process cocoa powder starts with cocoa beans that have been washed in potassium carbonate which neutralizes their acidity.
Since Dutch-process cocoa powder is neutral, it does not react with baking soda.
When baking, Dutch-process cocoa is often paired with baking powder.
Dutch-process cocoa powder can also be used in place of natural cocoa powder in recipes that don’t require leavening.
These include sauces, hot cocoa, frostings, ice cream, pudding, etc.
If you only have Dutch-process cocoa powder on hand, you can substitute it for neutral cocoa powder.
Just make sure to add 1/8 teaspoon of cream of tartar, white vinegar, or lemon juice for every 3 tablespoons of cocoa powder called for in the recipe.
RAW CACAO POWDER
Raw cacao powder is different from natural and Dutch-process unsweetened cocoa powder.
It’s pure powder from the cacao bean and isn’t nearly as processed as both natural and Dutch-process.
Cocoa is processed at high heat, which destroys much of the nutritional benefits of the cacao seed.
Also, cocoa powder is often alkalized during processing to reduce acidity. The result is a product that’s less bitter and more soluble when added to liquids.
Cacao powder, on the other hand, is made of fermented – not roasted – seeds that are processed at low temperatures and then milled into a powder, ensuring its nutritional benefits and its bitter flavor are preserved.
You can use raw cacao powder in recipes that don’t specify Dutch-process cocoa powder, however it is best not to try to.
Compared to cocoa powder, cacao powder has a stronger flavor, it is not as absorbent as cocoa powder, and it is more acidic, so it will react differently with baking soda.
Sugar may seem very basic if you’ve baked before, but I’ve been asked about it before, so I’m explaining.
There are many different types of sugar, including white sugar, brown sugar, vanilla sugar, powdered sugar, turbinado sugar, and demerara sugar.
When a recipe – any recipe, not just mine – says “sugar” without specifying anything else, it is regular white sugar.
White sugar (sometimes called granulated sugar, table sugar, or white granulated sugar) is made of either beet sugar or cane sugar, which has undergone a refining process.
It is the easiest to find and most commonly used.
Brown sugar is white sugar with molasses added to it.
It is commonly used in chocolate chip cookie recipes, and it’s rare for a recipe that calls for brown sugar not to also call for white sugar as well.
When a recipe calls for “brown sugar” but doesn’t specify what type (light or dark), it is referring to light brown sugar.
In my recipes, you can use whatever type of brown sugar you have on hand whether it is dark brown sugar, light brown sugar, or demerara sugar – which is very common in Israel.
Just keep in mind that the flavor and color will be slightly different depending on what you choose to use.
Turbinado sugar is better known as “raw sugar”. But, despite this name, the sugar is not really “raw.”
Instead, it’s partially refined sugar that retains some of the original molasses.
The term “raw sugar” may also give off the impression that it is somehow healthier.
In reality, turbinado sugar is nutritionally similar to white sugar.
Demerara sugar is very popular in Israel and is especially delicious in tea, but is also used for baking.
Unlike white sugar, demerara sugar undergoes minimal processing and retains some vitamins and mineral.
However, it is still not much healthier than white sugar.
Vanilla sugar is not very common in the States. However, it is common in Israel and parts of Europe.
This is sugar that sat for an extended period of time with vanilla beans, giving it a vanilla flavor.
This type of sugar is common in the United Kingdom.
It has a finer grain than white (granulated) sugar and larger than powdered sugar.
Caster sugar is often called for in recipes for delicate baked goods like meringues, souffles, and sponge cakes.
You can use a 1:1 conversion rate between caster sugar and white (granulated) sugar.
Powdered sugar, sometimes known as confectioners’ sugar, is a sugar with a powdered texture.
This sugar is rarely, if ever, used for baking. Instead, it is used for dusting desserts and making frosting and icings.
In some countries, you can also find powdered vanilla sugar.
It is made the exact same way regular vanilla sugar is made. However, the sugar used is powdered instead of granulated.
Vanilla Extract vs Vanilla sugar
In my recipes, I don’t specify what kind of vanilla to use.
The reason for this is that in the States, vanilla extract is exclusively used.
Meanwhile in Israel, along with many European countries, vanilla sugar is common.
In most, if not all recipes, both vanilla extract and vanilla sugar can be used.
In recipes where vanilla sugar can be used instead of extract, you can replace them 1:1.
Replacing Sugar with Honey
If you’d prefer to use honey instead of sugar, you can do so with pretty good results.
Honey can be two or even three times as sweet depending on the honey, so for every 1 cup of sugar, you can use 1/2 to 2/3 cup honey.
Since honey adds liquid, you need to remove some to balance it out. For every cup of honey remove a 1/4 cup of liquid.
Also, it burns faster than granulated sugar, so you want to lower the baking temperature by 25 F or 4 C. In addition, check it early and often to avoid burning or overbaking.
Types of Vanilla
Vanilla comes from a pod commonly known as a “vanilla bean”, which comes from the vanilla orchids.
Vanilla pod has been used for flavoring since the Aztecs, and was introduced to Europe by a Spanish conquistador, along with cocoa.
Vanilla extract is created by soaking vanilla beans in alcohol for some time. This is the most commonly used type of vanilla.
Vanilla sugar is common in Europe and some parts of the Middle East, like Israel.
It is made from vanilla beans sitting in sugar, vanilla bean powder mixed with sugar, or sugar mixed with vanilla extract.
In some countries, like Italy, you can also find vanilla powdered sugar which is used for confections.
Vanilla paste is generally a specialty item. It is a thick paste that contains a blend of the scraped-out vanilla pod seeds and vanilla extract.
You can use it as you do vanilla extract and it will leave flakes of vanilla bean like you see in vanilla bean ice cream.
Imitation Vanilla, otherwise known as artificial vanilla or vanilla essence, is made from synthetic vanilla.
This is the compound that naturally occurs in vanilla beans and gives it its flavor.
Can I use imitation vanilla?
Many will tell you that you should use high quality vanilla, just like they say you should use the best cocoa.
However, most of us will probably not be willing to pay the hefty price that comes with exceptionally high-quality ingredients.
Overall, vanilla is very expensive, so the extract is as well.
So, if you’re not going to get regular quality vanilla extract, you might as well use imitation vanilla.
DO EGGS NEED TO BE AT ROOM TEMPERATURE?
The short answer is “no”. While a side-by-side comparison shows that baking with eggs at room temperature makes a better crumb, it’s not otherwise noticeable.
What are Eggs used for?
Eggs do three things in most recipes: they help bind the ingredients together, act as a mild leavening agent, and they add moisture.
EGG FREE OPTION
Eggs can be substituted with 1/4 cup of unsweetened apple sauce per egg. This means for recipes calling for 2 eggs, you’d need 1/2 cup of unsweetened apple sauce.
The reason applesauce makes a good binder is that it’s high in pectin. Pectin is a naturally occurring starch in fruits and berries that acts as a thickening agent and stabilizer in food.
This happens when combined with sugar and acid (if the fruit or berry isn’t naturally acidic).
Just keep in mind that it may change the flavor slightly.
ARE EGGS DAIRY?
No, eggs are not dairy. Dairy is milk and any food products made from milk, including cheese, cream, butter, and yogurt.
So, while eggs are an animal product, they are not dairy. In fact, eggs fall under the protein food group.
BAKING POWDER VS BAKING SODA
I’ve had a number of comments asking me questions about baking soda and baking powder.
I’ve also noticed that if the wrong one is used, things don’t come out as they should.
Using baking soda instead of baking powder can give your recipe a terrible metallic taste, while using baking powder instead of baking soda leaves your baked goods looking flat.
Baking soda is a leavening agent, which means it helps things rise.
It does this by creating carbon dioxide when it reacts to an acid, such as cream of tartar, lemon juice, yogurt, buttermilk, cocoa, and vinegar.
When the carbon dioxide is released, it causes the familiar texture and crumb in pancakes, cakes, quick breads, soda bread, and other baked and fried foods.
Baking soda works well with sourdough because sourdough is acidic. When combined, it makes a lighter product with a less acidic taste, since baking soda is alkaline.
A good rule of thumb is to use around 1/4 teaspoon of baking soda per 1 cup of flour.
Baking powder is also a leavening agent and it’s a mixture of baking soda, cream of tartar, and sometimes cornstarch.
Most baking powder sold is double-acting. This means that the leavening occurs in two steps.
The first time it’s activated is when baking powder gets wet, which is why you cannot prepare some batters ahead of time to bake later.
The second time is when the baking powder is exposed to heat. This happens when the batter is being baked or fried.
Since baking powder already contains an acid, it’s most often used when a recipe does not call for an additional acidic ingredient or too little of one.
A good rule of thumb is to use around 1 teaspoon of baking powder per 1 cup of flour.
WHY SOME RECIPES CALL FOR BOTH
Some recipes call for both baking powder and baking soda when the carbon dioxide created from the acid and baking soda is not enough to leaven the volume of batter in the recipe.
Too much baking soda gives a terrible metallic taste, so baking powder is added to give it more lift.
WHICH ONE IS STRONGER?
You may have already guessed the answer since baking soda is used to make baking powder, and you need more baking powder per cup of flour. But I’ll tell you anyway.
Baking soda is four times stronger than baking powder.
That’s why you will more often than not see recipes that only call for baking soda rather than recipes that only call for baking powder.
HOW LONG DO THEY LAST?
Baking soda is good indefinitely past its best by date, although it can lose potency over time.
A rule of thumb is two years for an unopened package and six months for an opened package.
However, to be honest, I’ve used very old baking soda with good results.
Like baking soda, baking powder is good indefinitely past its best by date, and can lose its potency over time.
For both opened and unopened, it’s ideal to use it within nine months to a year.
While storing it, make sure to keep it in a dry place and away from humidity.
HOW TO TEST IF IT’S STILL GOOD
To test baking powder, pour 3 tablespoons of warm water into a small bowl, add 1/2 teaspoon of baking powder, and stir.
If the baking powder is good to use, it should fizz a little.
To test baking soda, pour 3 tablespoons of white distilled vinegar into a small bowl, add 1/2 teaspoon of baking soda, and stir.
The mixture should rapidly bubble if the soda is fresh.
GLUTEN FREE OPTION
Gluten Free Flour
Substitute all-purpose gluten-free flour in place of all-purpose regular flour cup for cup.
Buckwheat flour is easy to find compared to most other gluten-free flours, and it adds a nice earthy nutty taste.
The downside is that it has a distinct flavor, so the change will be noticeable.
It’s also darker, so the color won’t be the same. Substitute cup for cup.
Rice flour can also be used and can be found in most Asian and health food stores.
White rice flour has a mild flavor and doesn’t change the color of the muffin or quick bread.
Since it doesn’t have much flavor, it’s best to use it with ingredients that do. Substitute cup for cup.
Oat flour is made from whole oats that have been ground into a powder, which can easily be done at home.
It gives more flavor and a chewier and crumblier texture than regular all-purpose flour.
Substitute 1 cup of all-purpose flour for 1 1/3 cup Oat Flour. To make 1 cup of oat flour, blend 1 1/4 cups of oats in a food processor until finely ground.
Note: oats must be marked gluten-free because they can get cross-contaminated in the factory.
BAKING AT HIGH ALTITUDES
The higher the altitude, the lower the air pressure, and the more difficult it is to bake recipes.
Increase 15 to 25°F. Since leavening and evaporation happen more quickly, the higher temperature helps set the structure of baked goods before they over-expand and dry out.
However, the baking at higher temperatures means products are done sooner, so decrease by 5-8 minutes per 30 minutes of baking time.
Adjustment for 3000 feet
- Reduce baking powder: for each teaspoon decrease 1/8 teaspoon.
- Reduce sugar: for each cup, decrease 0 to 1 tablespoon.
- Increase liquid: for each cup, add 1 to 2 tablespoons.
Adjustment for 5000 feet
- Reduce baking powder: for each teaspoon, decrease 1/8 to 1/4 teaspoon.
- Reduce sugar: for each cup, decrease 0 to 2 tablespoons.
- Increase liquid: for each cup, add 2 to 4 tablespoons.
Adjustment for 7000+ feet
- Reduce baking powder: for each teaspoon, decrease 1/4 teaspoon.
- Reduce sugar: for each cup, decrease 1 to 3 tablespoons.
- Increase liquid: for each cup, add 3 to 4 tablespoons.
Baking with Humidity
Humidity can have a big impact on how your baked goods come out.
This is because when humidity is extremely high (think 70 percent or more), baking ingredients like flour, sugar, salt, baking powder, and baking soda soak up moisture from the air.
This can negatively impact the outcome of your cakes, cookies, yeast breads, and quick breads.
There are some things you can do to try to save your baking.
Try to counterbalance the additional moisture
To help counterbalance the additional moisture your dry ingredients soak up from the air, try reducing the amount of liquid in the recipe by about one-quarter.
If the batter or dough looks too dry once all the ingredients are mixed together, add additional liquid tablespoon at a time until you have the desired consistency.
This is not usually possible to do for cookies, but it does work for cakes and breads.
Store Ingredients in the Fridge
If flour and sugar are stored in the refrigerator or freezer rather than in a cupboard or pantry, they are better protected from humidity.
As an added benefit, keeping these ingredients cool also helps keep them fresher longer, in addition to helping them stay bug-free.
For best results, let them warm to room temperature before using.
Bake for Longer
If you bake your goodies for a few extra minutes, it can help the liquid to cook off.
To avoid overbaking, continue testing for doneness every couple of minutes for breads, quick breads, cakes, cupcakes, and muffins. Cookies, on the other hand, need to be checked every minute.
Use Air Conditioning
To help lower humidity levels on humid summer days, air condition the room for at least an hour before you start baking.
Cooler air isn’t able to hold as much moisture as warm air.
Store your baked goods in an airtight container
Humidity can also ruin your fresh-baked goods because when they are left out they can absorb moisture.
To avoid this, store them in an air tight container or resealable bag.
WHY IS IT TAKING LONGER THAN DESCRIBED TO BAKE?
Over time, the thermostat on ovens gets a little off, causing some ovens to run hot and others to run cool.
This is why recipes tend to say things like “10 to 15 minutes or until golden brown.”
So, if it takes you longer than expected that’s fine, don’t worry about it. just keep baking until ready.
WHY DID MY RECIPE COME OUT TOO DRY?
Just like some ovens run cool, others run hot. If your oven runs hot, bake these at a lower temperature.
Ideally, you should get an oven thermometer to know what temperature you’re really baking at.
How to store muffins
Let muffins cool fully. Transfer the muffins to an airtight container lined with a paper towel. Place a second paper towel on top of the muffins before sealing.
If using a zip-top plastic bag, line both sides of the bag with paper towels and remove as much air as possible before sealing the top of the bag.
Store at room temperature for up to 4 days.
How to Freeze muffins
Let muffins cool fully. Wrap each muffin individually in plastic wrap, then place them in a zip-top bag.
Freeze for up to 2 months. They will still be safe to eat after two months, but their quality begins to degrade.
When ready to eat, let thaw at room temperature or rewarm gently in a counter top oven or microwave.
Chocolate Walnut Muffins Tip:
Place some chopped walnuts on the top and lightly push them into the batter. This will give you walnuts that sit on top as well as mixed in.
