Passover Chocolate Cake

You'll never need another Passover chocolate cake after trying this one!  If you are gluten free, you need this cake. It is moist, light, fluffy, and has a perfect crumb.  I cannot say enough good things about it!

There is nothing like finding the perfect recipe.  It's pretty much a miracle to find the perfect Passover cake recipe.  

Well, get ready to thank your lucky stars because this is the most moist, lightest, and fluffiest chocolate cake I've ever had.  

It may actually be even better than my dairy free chocolate cake which is pretty darn good...

Seriously, its flavor is so good I feel guilty eating it on Passover!  

It feels like I'm eating a really good regular chocolate cake… I think it's fair to describe it as "sinfully good!"  It is so good it feels wrong.     

The best part?  Not only is it dairy free, but it is totally gluten free.  

So, if you have Celiac disease, you can make it year-round and no one will be the wiser that it doesn't have one speck of flour in it.  

It doesn't require any special ingredients except potato starch, which is pretty cheap.

One of my favorite things about this cake is the top.  Just look at that thin flaky layer!

It gives the cake so much character and looks very pretty.  

Even better, it looks beautiful when dusted with powdered sugar.

If you like this chocolate cake, you'll probably also really enjoy my passover chocolate brownies, my passover cheesecake, and my passover coconut macaroons.

History of Chocolate Cake

In case you were wondering, celebrating birthdays with cakes stems back to ancient Rome. A flat circular cake made from flour and nuts, leavened with yeast, and sweetened with honey was served at weddings and special birthdays.

In the 1400s, bakeries in Germany started to market one-layer cakes for customers' birthdays. These birthday cakes, and even wedding cakes, were pretty simple. 

It wasn't until 200 years later that birthday cake was made more elaborate with multiple layers, icing, and decorations. However, these cakes were only available to the very wealthy until the industrial revolution.

Chocolate cake, however, did not yet become a thing. This is because chocolate was very expensive and exclusive luxury afforded by the wealthy.

However, when they figured out how to make powdered cocoa, it transformed chocolate into an inexpensive daily snack. 

Then, about 50 years later, Rodolphe Lindt, as in Lindt chocolates, created process for making silkier and smoother chocolate, which made it easier to bake.  

Still, chocolate was mostly used for hot chocolate drinks and as fillings and glazes for cakes. It was only in 1886 that American cooks began adding chocolate to the cake batter, creating chocolate cake.

The recipe in print for Devil's food cake was as early as 1905.  Devil's food cake is a chocolate cake that gets its name because it is considered a counterpart to angel food cake which is the white.

There really is no strict way to depreciate Devil's food cake from regular chocolate cake, though some say it calls for more chocolate.

How can leavener be used because of "unleavened bread"?

Because this is a cake, not bread.

How to Measure Flour and Other Dry Ingredients

The best way to measure dry ingredients is with a scale, but in the United States, dry measuring cups are usually used instead.

Weighing ingredients is useful for home bakers, but it's especially important for professional bakers because they work with huge batches. 

I usually use dry measuring cups when baking too, because I didn't grow up in a country that generally weighs ingredients, so please don't feel like you can't use them.

To measure most dry ingredients, first spoon them into a dry measuring cup and then level off the measuring cup with an upside-down butter knife.

Make sure not to pack it down because this will cause you to use more of the ingredient than the recipe calls for.

Brown sugar is the exception to the rule, though. To measure brown sugar, pack it into the measuring cup and then level off any excess.

To measure chocolate chips, nuts, or dried fruit, just pour them into the dry measuring cup and then level them off.

What are dry measuring cups?

Dry measuring cups are the set of cups that usually come with measuring spoons. Each cup is a different measurement, just like each spoon is a different measurement.

Liquid measuring cups, on the other hand, are the cups that usually hold more than one cup and have lines on the side that mark the measurements.

The problem with using liquid measuring cups to measure powdery dry ingredients, like flour and cocoa, is that you shake the cup to level them off. This causes the powder to settle, and you end up with more than you need.

I tested this with a friend who didn't believe me, and we ended up with a quarter cup more flour than the recipe called for.

Should I sift the potato starch and other dry ingredients?

It's usually recommended to sift your powdery ingredients, like flour and cocoa, before using them.

Sifting aerates the flour and removes any lumps, which helps make baked goods fluffier.

It also helps you get a more accurate measurement than when you use flour that's been packed tightly in a bag.

And sifting dry ingredients together, like potato starch, cocoa, and baking powder, helps make sure they're evenly distributed in the batter. Which honestly, I think is probably overrated, so I personally never bother with it.

Which Type Of Oil should i use?

I don't specify in the recipe which type of oil to use because it's mostly personal preference and I don't want anyone to feel they have to use specifically that type of oil. For the most part, you can use whatever oil you feel most comfortable using.

I use neutral oils like canola oil, safflower oil, and vegetable oil.

You can also use stronger oils like olive oil and coconut oil, but keep in mind that they may change the taste somewhat.

If you're going to use olive oil, use the one labeled pure olive oil because it has the mildest flavor. This should make the flavor a lot less noticeable.

Is It Better to Use Canola Oil or Olive Oil?

Canola oil is relatively cheap and, due to its lack of flavor and high smoke point, is very versatile.

Olive oil, on the other hand, is generally considered a healthier choice.

So, really, it's whatever you prefer.

How to Store Oil

Store oils in a cool, dark place to prevent them from becoming rancid.

If you store them in the fridge, some oils, like olive oil, may solidify and look strange, but don't worry, they'll return to normal at room temperature.

Coconut oil begins to solidify in temperatures under 76°F or 25°C.

Which Type of Cocoa Should I 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, Dutch-processed cocoa powder, and raw cacao powder.

Natural cocoa powder is your basic non-specialty cocoa powder, and it's the one you should use natural unsweetened cocoa powder for this recipe.

Natural cocoa powder is the most commonly used type of cocoa powder and is what you should use in most recipes, such as brownies, chocolate cupcakes, hot chocolate, or any recipe that simply says "cocoa powder."

Can I Use Dutch-Processed Cocoa Powder?

Dutch-processed cocoa powder starts with cocoa beans that have been treated with potassium carbonate, which neutralizes their acidity.

Since Dutch-processed cocoa powder is not acidic, it does not react with baking soda the way natural cocoa powder does.

Recipes that rely on natural cocoa powder for the acidity to trigger the baking soda may not rise properly if you replace the natural cocoa with Dutch-processed cocoa.

For this recipe, I recommend sticking with natural cocoa powder, though I have had readers who switched it out and liked the results. So if you want to try it, that's totally up to you.

Can I Use Raw Cacao Powder?

Raw cacao powder is different from natural and Dutch-processed cocoa powders.

It's made from the cacao bean and isn't nearly as processed. It comes from seeds that have been fermented and are processed at low temperatures to ensure that their nutritional benefits and bitter flavor are preserved.

You can use raw cacao powder if you really want to, but I don't recommend it, since it's not as absorbent as cocoa powder, and it may cause the recipe to be too liquidy and not bake properly.

Can I Use Sweetened Cocoa?

Sweetened cocoa is natural cocoa powder mixed with sugar.

Please don't use it when making this recipe because it will make it too sweet.

How to Substitute Chocolate With Cocoa Powder in Recipes

This recipe calls for cocoa powder, so you really don't need to worry about this here, but I've found this so helpful (and honestly, I had to work hard to figure this out) so I'm sharing it with you anyway.

It's also really useful if you pair this recipe with another recipe that calls for melted chocolate, so I'm including it in case you need it...

Just make sure to mix the ingredients together in a bowl first before adding them to the rest of the recipe.

Cocoa Substitute for Sweet Baking Chocolate

To replace 4 ounces of sweet baking chocolate, use ¼ cup unsweetened cocoa powder plus ⅓ cup sugar and 3 tablespoons oil.

Cocoa Substitute for Semisweet and Bittersweet Baking Chocolate

To replace 4 ounces of semisweet and bittersweet chocolate, use ¼ cup unsweetened cocoa powder plus 2 ½ tablespoons sugar and 3 tablespoons oil.

Cocoa Substitute for Unsweetened Baking Chocolate

To replace 4 ounces of unsweetened chocolate, use ¼ cup unsweetened cocoa powder plus 3 tablespoons oil.

How to Store Cocoa

Store cocoa in an airtight container and keep it in a cool, dark place to prevent it from absorbing moisture and losing flavor.

Pro Tip: I store cocoa powder in a large canister so it doesn't make a mess when I go to use it. Doing this has made baking with cocoa so much easier and way less messy!

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 three reasons for this:

First, coffee helps enrich the chocolate flavor. 

Second, the heat from the water helps bloom the cocoa. 

Third, coffee is acidic, which makes the cake a little extra tender.

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 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 that you still bloom the cocoa.

Sugar

The primary role of sugar is to be a sweetener. However, sugar also contributes to the tenderness and moistness of the baked good by absorbing and retaining moisture and helps create the golden brown color when baking as it caramelizes.

Recipes with more sugar often result in softer, moister textures. However, I learned the hard way that too much sugar leads to a sticky mess.

When it's heated, sugar caramelizes, resulting in a rich, complex flavor and a brown color. This adds both flavor and color to baked goods and is also the process in which caramel sauce, dulce de leche, caramel candies, and regular candies are made.

When used in recipes containing yeast, the sugar is eaten by the yeast, producing carbon dioxide and causing the dough to rise.

Sugar also acts as a preservative in jams, jellies, and fruit preserves by reducing water activity and preventing microbial growth.

There are many different types of sugar, including white sugar, brown sugar, vanilla sugar, powdered sugar, turbinado sugar, and demerara sugar.

When a recipe calls for "sugar" without specifying anything else, it's referring to regular white sugar.

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

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

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

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 minerals.

However, it is still not much healthier than white sugar.

Vanilla 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.

Caster Sugar

This type of sugar is common in the United Kingdom.

It has a grain finer 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

Powdered sugar, sometimes known as confectioners' sugar, is a sugar with a powdered texture.

This sugar is rarely used for baking. Instead, it is used for dusting desserts and making frosting, icing, and glazes.

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 ½ to ⅔ cup honey.

Since honey adds liquid, you need to remove some to balance it out.  For every cup of honey, remove a ¼ cup of liquid.

Also, it burns faster than granulated sugar, so you want to lower the baking temperature by 25°F.  In addition, check it early and often to avoid burning or overbaking.

How to Store Sugar

Sugar should be stored in an airtight container to prevent clumping and moisture absorption, and kept in a cool, dry place.

Do Eggs Need to Be at Room Temperature?

The short answer is "no."

While a lot of recipes call for room-temperature eggs, the difference is only noticeable if you do a side-by-side comparison, and even then, the difference is very slight.

How Can I Tell if My Eggs Are Still Good?

Fill a glass with cool water and submerge the eggs.

If the eggs sink to the bottom and lay flat on their side, they're still fresh.

If they sink but stand on one end at the bottom of the glass, the eggs are older but still good to use.

If an egg floats to the top, it's very old and should be checked carefully for signs of spoilage before using.

Can I use baking soda and baking powder interchangeably?

No. Even though baking soda and baking powder are both leavening agents that make things rise, they work differently and aren't generally interchangeable.

When baking soda (also known as sodium bicarbonate) is combined with acidic ingredients, it makes carbon dioxide. This helps batter or dough rise and gives baked goods a light, fluffy texture.

That's why baking soda is commonly used in recipes have acidic ingredients, like buttermilk, lemon juice, vinegar, or natural cocoa powder.

Baking soda is also roughly four times as powerful as baking powder, so you don't need a lot of it. Using too much can actually give your baked goods a bitter or metallic taste.

Baking soda needs enough acid to react with it, so substituting it for baking powder can leave things flat and tasting off.

Baking powder, on the other hand, is a combination of both baking soda and an acid, so it doesn't need an acidic ingredient in the recipe to create carbon dioxide.

This makes baking powder useful in recipes that don't have enough acidic ingredients to activate baking soda. For example, it's commonly used in recipes like matzo balls and biscuits.

Because baking powder is less powerful than baking soda, recipes generally call for more of it. So, if you try to use baking soda instead of baking powder, the texture won't come out right and the flavor will probably taste disgusting.

Why do some recipes call for both?

Some recipes use both baking soda and baking powder because they do slightly different things.

For example, my chocolate cake has enough acid for baking soda to react with it, but if you'd use enough baking soda to give the cake the lift it need, it would ruin the flavor and you'd have to throw the cake out.

So, instead of adding more baking soda, the recipe uses baking powder to give additional rise.

How can I tell if baking soda and baking powder are still good?

Both baking powder and baking soda can continue to be used well past their best by dates, but they become less potent over time and can eventually stop working altogether.

To test baking soda, pour 3 tablespoons of white distilled vinegar into a small bowl, add ½ teaspoon of baking soda, and stir. The mixture should rapidly bubble if the baking soda is still active.

To test baking powder, pour 3 tablespoons of warm water into a small bowl, add ½ teaspoon of baking powder, and stir. If the baking powder is still active, it should fizz.

Can you use baking powder on Passover?

Absolutely! As long as the box is marked kosher for Passover with a "P" next to the kosher symbol.

I get this question a lot because of the fact that it is a leavener. The truth is though, while laws regarding Passover are complex, the focus is on wheat flour rather than the leavener itself.

In fact, there wasn't anything to leaven bread in ancient times except wild yeast.

So, the bread they were making was something of a sour dough bread. This is the reason it took so long to rise.

Also, baking powder and baking soda are artificial leaveners, so they wouldn't count anyway.

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 a 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 the 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 airtight container or resealable bag.

Adjusting for a Convection Oven

Convection ovens blow the hot air around, producing around 25 to 30 percent more heat.

Since convection ovens produce more heat, you need either lowering the temperature or shortening the cooking time to compensate.

When recipes specify temperatures and cooking times, it's for conventional ovens, unless specified otherwise.

A simple rule to follow is to lower the temperature by 25ºF or 14ºC when baking cookies and pies, and 50ºF or 28ºC when roasting meat and poultry. Some convection ovens offer separate settings for baking and for roasting.

You can also leave the temperature the same and instead, shorten the cooking time by 25 percent. For example, if your recipe calls for 60 minutes in the oven, check the food after 45 minutes instead.

However, keep in mind, some convection ovens actually make a heat adjustment for you. That is, if you set a convection oven for 350ºF, it might actually set itself to 325ºF to compensate. So, check your manual before making adjustments.

Can I use round pans?

For this recipe, you can use two 9-inch round cake pans or three 8-inch round cake pans. If you do, the cake may need 10 minutes less of baking time, so start checking it early.
