Blend the cottage cheese, eggs, milk, maple syrup, vanilla, and orange zest until smooth.
Whisk the oat flour, cocoa powder, protein powder, baking powder, and salt in a bowl. Stir in the blended mixture until no dry streaks remain.
Mix the Greek yogurt, maple syrup, orange juice, and orange zest in a small bowl to make the drizzle.
Heat a lightly greased skillet over medium-low heat. Cook the batter in small 1/4-cup portions until bubbles appear on the surface.
Flip each pancake and cook for 1 to 2 minutes more. Keep the heat moderate so the cocoa pancakes cook through without drying out.
Stack the pancakes and drizzle with the orange yogurt. Sprinkle with dark chocolate chips and candied orange peel.
