🍪 Ingredients

• vanilla whey protein powder
• peanut butter
• banana
• vanilla extract
• ground cinnamon

👩🏼‍🍳 Instructions

Preheat your oven to 325F (160C).

Mix all ingredients.

Drop spoonfuls of batter on a parchment-lined baking tray.

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.
