Ingredient tips and substitutions

Oat flour: Lotsa oats for texture, nutrition, and cookie flavor. You can make your own by blending oats into a fine powder. Use certified gluten free if needed.
Vanilla plant protein: For a protein boost and extra sweetness. I like to use a pea and rice blend. I have not tried these with whey. If you don't have protein powder, you should be able to sub any combo of oats, ground flax or almond flour, but they will be less sweet.
Cashew butter: Even more cookie flavor plus healthy fats for mouthfeel and optimal texture. You can use almond butter but they'll be darker and strong in flavor. Peanut butter is a bit more dry and will give a strong peanut flavor. Use sunflower seed butter for nut-free.
Maple syrup: For a hint of extra sweetness. Honey syrup or agave will also work.
Almond milk: a splash to bring the batter together. Any milk will do.
Vanilla extract: For authentic vanilla cookie flavor!
Baking soda: Purely for cookie flavor; you can totally omit if you'd like.
Chocolate chips: To get that thick layer or chocolate on top.

What kind of protein powder is best?

I always go with plant-based protein powder that's a blend of pea and rice because I love plants! I haven't tried these with whey since I don't cook with it. This and this are my favorite plant-based protein powders. They're also great with these vanilla collagen peptides.

You want one that's sweetened versus unflavored, as that contributes to the overall taste of these bars. If less sweet bars are your jam, feel free to try unsweetened protein.

If you don’t have protein powder, you can try swapping it out for more oats, or even throw some ground flaxseed in there!

How to store bars

I like to store my bars in fridge for up to a week, but they can also be stored at room temperature.

Can you freeze protein bars?

Yes! You can freeze them for up to three months. They're delish right out of the freezer, too!
