Preheat oven to 350ºF. Line a baking sheet with parchment.
Place oats, cocoa powder, protein powder, liquid sweetener of choice, coconut oil, almond milk, peppermint extract, and baking powder in a blender.
Blend until mostly smooth, some small pieces of oats should still be visible.
Transfer dough to a large bowl. Fold in the chocolate chips until evenly distributed.
Roll and shape dough into 12 even balls. Place balls on prepared cookie sheet. Flatten balls with with the palm of your hand (they don’t spread much in the oven so size going in will be similar to size coming out).
Bake cookies for 7 minutes. Let cool and enjoy!
*I used honey but agave nectar or date syrup also work,
