- banana
- vanilla extract

Bake for 8-10 minutes.
Enjoy!
🍫 Substitutions
This would be great with other flavor whey protein powders, like this strawberry whey, or this natural chocolate whey. I don't think plant protein powders would work well here, because the banana would make the recipe too wet (like wet sand). But this recipe for chocolate protein cookies can be adapted to vanilla plant protein and peanut butter, if you like!
🌰 Variations
Using almond butter or cashew butter in place of the peanut butter work well and be very delicious!
In place of the mashed banana, you'd want something of the same consistency, like pumpkin puree, perhaps. Pumpkin and almond butter would be a great combo, or even pumpkin and cashew butter.
🥣 Equipment
You'll need an oven (or toaster oven), a cookie sheet or some kind of baking pan, and I suggest using parchment paper to keep the cookies from sticking (and for easy clean up).
I always suggest using an oven thermometer to check the oven temperature. You'd be surprised at how off an oven can be, even a brand new oven.
You'll need a bowl to mix things up, of course. If you're looking for nice mixing bowls, I love this set of mixing bowls from Target. It is reasonably priced, and the bottoms of the bowls have rubber for non-slip mixing.
🥡 Storage
These store well refrigerated in airtight containers or ziplock bags.
⚡️ Meal prep tip
Bake up several batches at a time for snack prep! Store them in ziplock bags or small containers for easy grab-and-go meal replacements.

These are so good! I had weight loss surgery and have been looking for recipes that have a lot of protein. These are way way better then premade protein cookies. I added a square of Lilly's chocolate bar to the center of each one for a little chocolate hit...Chef's Kiss!!

Hi Emily,
I would store them in the refrigerator for about a week. They can stay out for a day, but for longer storage I'd keep them in the fridge.
Thanks for writing in!
