Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Mix Ingredients
In a mixing bowl, combine nut butter and sweetener until smooth. Gradually add protein powder and mix well. Slowly fold in the oatmeal to form a dough.
Shape the Cookies
Use a spoon or cookie scoop to divide the dough into 4 equal portions. Roll into balls, place them on the baking sheet, and flatten slightly with the back of a spoon.
Bake
Bake for 8-10 minutes, or until the edges are golden brown. Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
Serve and Enjoy
Your 4-ingredient protein cookies are ready to enjoy! Perfect as a post-workout snack or a mid-day energy boost.
