Blend the cottage cheese, eggs, milk, maple syrup, and peppermint extract until completely smooth.
Whisk the oat flour, cocoa powder, protein powder, baking powder, and salt together. Stir in the blended mixture, then fold in the chocolate chips.
Mix the Greek yogurt, maple syrup, and peppermint extract in a small bowl. Keep the mint flavor subtle because peppermint extract is concentrated.
Cook the pancakes in a lightly greased skillet over medium-low heat. Use 1/4 cup batter per pancake and cook until bubbles appear.
Flip and cook for 1 to 2 minutes more, taking care not to overcook the chocolate pancakes.
Serve with the mint yogurt topping and extra chocolate chips.
