Ingredient Substitutions
This recipe only works with a whey/casein blend protein powder. Other types of protein powder, such as whey protein and vegan protein powder, absorb liquid differently and do not provide the same structure. Here is a recipe for banana whey protein cookies and banana peanut butter whey protein cookies.
Recipe Variations
Chocolate Protein Powder: Swap vanilla protein powder for chocolate protein powder for chocolatey deliciousness.
Chocolate Chip Protein Cookies: Mix in sugar free dark chocolate chips to switch things up.
Spice it up: Add a pinch of cinnamon for some delicious warmth.I love this Vietnamese cinnamon for its bold flavor.
Vanilla boost: Add ½ teaspoon vanilla extract. I love this baking vanilla not only for the vanilla flavor, but because it is low alcohol and reasonably priced.
Go coconutty! Add a tablespoon or two or shredded unsweetened coconut and a teaspoon or two of coconut sugar.
Make it sweet: For a sweeter cookie, I recommend adding a granulated or powdered sweetener (like erythritol, stevia, or monk fruit).
Storage Information
Store these healthy cookies in an airtight container in the refrigerator for 3-5 days. I don't think they would freeze well ( I think they would dry out quickly).
FAQ
No, this recipe requires a whey/casein blend protein powder. Vegan protein powder, whey, or collagen will not produce the same texture.
Keep mixing the ingredients. The moisture from the mashed bananas eventually combines with the protein powder to form a smooth batter.
No, using parchment paper prevents sticking without the need for non-stick cooking spray or coconut oil.
