🍪 Ingredients

The banana peanut butter high protein cookies feature ingredients that provide both flavor and nutrition.

Vanilla Whey Protein Powder

​The main source of protein in this recipe, vanilla whey protein powder, ensures the cookies deliver a high-protein punch.

The whey protein powder also helps bind the ingredients together, creating a chewy texture.

I highly recommend whey protein concentrate, as whey isolates tend to bake up dry and rubbery.

Unsweetened Peanut Butter

​Natural peanut butter provides healthy fats and protein while keeping the cookies moist and flavorful. It serves as the primary fat source, balancing the texture and adding richness.

Mashed Banana

​Ripe or overripe bananas add natural sweetness and moisture, reducing the need for added sugar. Banana also enhances the flavor, making the cookies taste naturally sweet.

Vanilla Extract

​A small amount of vanilla extract enhances the overall flavor of the cookies, adding warmth and depth. I like this baking vanilla for its flavor and low alcohol content.

Ground Cinnamon

​A dash of ground cinnamon adds a subtle spice, complementing the peanut butter and banana flavors. I prefer Vietnamese cinnamon for its bold flavor.

🥣 Equipment Needed

Kitchen Scale: I highly recommend using a kitchen scale for accurate measurements and easy cleanup. 

Cookie Sheet: A quality cookie sheet ensures even baking. I like these Airbake cookie sheets.

Parchment Paper: Parchment paper prevents the cookies from sticking to the cookie sheet and makes cleanup easy.

Mixing Bowl: A medium bowl is needed to mix all the ingredients. I like this mixing bowl set because of the non-slip bottom and smooth inner surface.

Spoon: Use a spoon to mix the ingredients and drop the cookie dough onto the baking sheet.

Oven Thermometer: I never bake without an oven thermometer! You'd be surprised at how often ovens are off temp, and this is important when baking with protein powder. Over-baked protein bakes can be dry and unpalatable. 

Cooling rack: Using a cooling rack allows for more even cooling, as the room temperature air can get below the cookies.

👩🏼‍🍳 Instructions

1. Preheat the oven to 325°F (163°C). Use an oven thermometer for best results.

2. Combine all ingredients in a mixing bowl until the cookie dough is smooth and well-mixed.

3. Drop spoonfuls of the batter onto a parchment-lined baking sheet, leaving space between each cookie.

4. Bake for 8-10 minutes or just until the cookies are firm.

Enjoy!

🍪 Substitutions

Peanut Butter: Other types of nut butter would work just as well in place of the peanut butter. Almond butter or cashew butter would be delicious! Sunflower seed butter should work as well.

Banana: Other mashed fruit can work here, just be sure to drain extra moisture so that the mashed fruit has the same consistency as mashed banana. Canned pumpkin can also work here!

Vanilla Whey Protein Powder: This recipe was designed for whey protein concentrate. I don't recommend other types of protein in this recipe. But other flavors of whey concentrate would be great!

🌰 Variations

Enhance these healthy protein cookies with some simple variations:

Chocolate Chip Protein Cookies: Turn these into indulgent chocolate chip cookies by adding dark chocolate chips. I like these sugar-free dark chocolate chips.

Peanut Butter Oatmeal Protein Cookies: Mix in a small amount of quick oats or old-fashioned oats for a heartier texture.

Extra Sweet: Add a tablespoon or two of coconut sugar for a sweeter cookie.

3 Ingredient Cookies: Simplify the recipe by omitting the vanilla and cinnamon. The cookies will still be delicious!

🥡 Storage

These banana peanut butter cookies can stay at room temperature for the day, but for longer storage I'd keep them in an airtight container in the refrigerator (up to a week).

These protein cookies can also be frozen for up to 3 months. Wrap them in plastic wrap and keep them in a freezer-safe airtight container.
