The healthy peanut butter cookies are made with powdered peanut butter, and the centers are made with a chocolate whey protein powder.

For the filling I used this chocolate whey protein. I love it for brownies, protein fudge, and any recipe in which you'd want a super-chocolatey flavor. Perfect here!

Wow your holiday guests or keep all of these peanut butter thumbprint cookies for yourself! Give them a try. :)

Cookie:

  • ¼ cup (64 g) natural peanut butter
  • 2 (66 g) large egg whites or 1 flax egg
  • ½ cup (48 g) powdered peanut butter
  • 1 teaspoon (4 g) baking powder
  • 4 mini-scoops stevia powder or to taste

 

Chocolate filling:

  • ¼ cup (26 g) chocolate whey protein powder
  • 1 ½ tablespoons (23 ml) filtered water or as needed

Instructions
 

  • Preheat oven to 325F (163C).
  • Mix peanut butter and egg whites until combined and smooth.
    ¼ cup (64 g) natural peanut butter, 2 (66 g) large egg whites
  • Add powdered peanut butter, baking powder, and stevia. Mix well, using your hands if necessary.
    ½ cup (48 g) powdered peanut butter, 1 teaspoon (4 g) baking powder, 4 mini-scoops stevia powder
  • Roll cookie dough into 12 balls, and place on a parchment-lined cookie sheet.
  • Using your thumb or the back of a teaspoon measuring spoon, press into each cookie.
  • Bake for about 10 minutes, until cooked and firm.
  • Let cool.
  • Mix chocolate whey with just enough water to get an icing consistency.
    ¼ cup (26 g) chocolate whey protein powder, 1 ½ tablespoons (23 ml) filtered water
  • Spoon into each cookie cavity.
  • Enjoy! Store in the refrigerator.

Notes

Powdered peanut butter gives these protein cookies an extra flavor boost! If you would like to sub a different protein powder there, I suggest using a plant-based protein (pea protein blend). 
For the center, I don't recommend using a different type of protein powder. For a vegan filling, I suggest making a vegan chocolate ganache.

    Hi Cate. If you're just adding a teaspoon or so of date syrup, that should be fine. But more than that might make the cookie dough too wet. If you want to give it a try, consider adding more powdered peanut butter (if needed) to keep a cookie dough consistency.
    Hope this helps!

    Could you substitute date syrup for the stevia?
