Do Smoothies have Dairy?
Smoothies don’t have to, but they usually contain dairy because they usually are made with milk and/or yogurt.
What Type of Oat Milk should I use?
Any oat milk will work. Oat milks with a stronger oat flavor are not ideal though, unless you want that oaty flavor.
Personally, I like using oat milks that don’t actually taste like oats, even if I am adding oats into the smoothie.
I really like to let the smoothie’s flavor shine because it is oh so good.
What Type of Dairy Free Yogurt Should I use?
You should use a neutral or vanilla flavored dairy free yogurt.
Yogurt made from soy, almonds, coconut, and oats all will work fine here.
What if I don’t have or want yogurt in my smoothie?
The yogurt makes the smoothie creamy, but it can easily be left out if you prefer.
All you have to do is switch the yogurt out for more oat milk.
How To Freeze Fruit For Smoothies
To make smoothies even easier, freeze fresh fruit into portions.
To freeze bananas for smoothies, peel the bananas and cut them into round disks.
Arrange, in one layer, on a parchment paper-lined baking sheet. Slide the baking sheet into the freezer and freeze until hard (two to three hours).
When the bananas are hard, divide it between freezer-safe bags and keep it in the freezer for your next smoothie.
If you’d prefer the lazy way, I often just stick a full banana into a freezer safe bag and blend it whole.
Banana Smoothie Variations
If you’re looking for a plain banana smoothie, this recipe alone is delicious. However, I’ve given a list of optional additions if you’d like.
Add the listed amount of peanut butter for a peanut butter banana smoothie.
Add oats to make this banana smoothie a breakfast banana smoothie.
Or, you can add both oats and peanut butter to make a peanut butter banana breakfast smoothie.
If you don’t use extremely ripe bananas (or over ripe bananas), you may not find it sweet enough, which is where the honey comes in.
Make Ahead of Time
You can easily make this recipe ahead of time.
All you have to do is put the bananas, yogurt, and anything else you want in the blender – except oats, if you plan on using them.
Blend it up until it is nice and smooth. Then, pour the smoothie into a freezer safe resealable bag.
Once you’re ready to use the smoothie, let it sit out until it’s defrosted enough to put into the blender.
Place the smoothie in the blender, add the milk and oats if desired, then blend until smooth again. Once it has a nice pourable consistency, put it in a cup, and serve.
