Preheat oven to 350 degrees Fahrenheit and line a baking sheet with parchment paper and set aside.
In a large bowl, mix together peanut butter, protein powder, maple syrup, coconut sugar and salt with a wooden spoon until combined.
Using a cookie scoop, scoop 16 balls of dough onto baking sheet, spaced about an inch apart. Flatten balls into disks by pressing down gently with the tines of two forks, or with one fork pressing down twice, creating a crosshatch pattern.
Bake cookies in preheated oven for 10-12 minutes until edges are golden brown.
Transfer cookies to a wire rack to cool. Serve cookies warm or at room temperature.
Notes
*You may omit the protein powder if you like, just use ⅔ cup coconut sugar and no maple syrup so that the cookies hold their shape
