Ingredients

1 cup mashed ripe bananas

¼ cup dark cocoa powder

½ cup all natural creamy peanut butter

½ cup chocolate protein powder

Dark chocolate chips

Protein cocoa dough.

Ingredient Notes

Bananas

Use very ripe bananas with brown spots. They provide natural sweetness and moisture.

Cocoa Powder

Dark cocoa or black cocoa gives these cookies a rich, deep chocolate flavor and darker color.

Peanut Butter

Use natural creamy peanut butter with just peanuts and salt. Avoid brands with added sugar or oils for best texture.

Protein Powder

Chocolate protein powder works best. Whey protein creates a softer texture. Plant based protein may make the dough slightly thicker.

Chocolate Chips

Dark chocolate chips enhance the richness and make each bite extra indulgent.

How To Make Chocolate Protein Cookies

First, preheat your oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper.

In a large mixing bowl, combine the mashed bananas, cocoa powder, peanut butter, and protein powder. Stir together. The dough will be a little looser than regular cookie dough.

Fold in the chocolate chips.

Use a spoon to scoop balls of dough onto the lined pan. They will be a little runny and gooey.

Finally, remove from the oven. Cool on the pan for 10 minutes before eating.

Frequently Asked Questions (FAQs)

Are chocolate protein cookies healthy?

Chocolate protein cookies can be a healthier dessert option when made with simple ingredients like bananas, natural peanut butter, and protein powder. They are higher in protein and lower in refined sugar compared to traditional cookies.

Can I use whey protein instead of plant based protein?

Yes. Whey protein creates a softer, slightly more tender cookie. Plant based protein tends to absorb more moisture, so you may need to add a splash of milk to adjust the batter consistency.

Why are my protein cookies dry?

Protein cookies can turn out dry if they are over baked or if too much protein powder is used. Bake just until the edges are set and allow them to cool on the pan to finish setting.

Why are my protein cookies too gooey in the middle?

These cookies are meant to be soft and fudgy. However, if they seem under baked, return them to the oven for 1 to 2 additional minutes until the edges are firm.

Can I make these protein cookies without banana?

Banana provides natural sweetness and moisture in this recipe. If you replace it, the texture and flavor will change significantly. You may need to experiment with unsweetened applesauce or Greek yogurt, but adjustments will be required.

Do protein cookies spread while baking?

No. These cookies do not spread much because they are flourless and high in protein. Shape them into rounds before baking.

Are these protein cookies gluten free?

Yes. As long as your protein powder is certified gluten free, this recipe is naturally gluten free since it contains no flour.
