  • 1/4 cup protein powder (vanilla or unflavored)
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda

  7. Bake for 12 to 15 minutes, or until the edges are lightly golden brown.
  8. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
