Blend the cottage cheese, eggs, milk, maple syrup, and vanilla until completely smooth.
Whisk the oat flour, cocoa powder, protein powder, baking powder, and salt in a bowl. Stir in the blended mixture, then gently fold in the fresh raspberries.
Stir the cornstarch and water together in a small saucepan. Add the frozen raspberries, maple syrup, and lemon juice, then cook over medium heat until thick and glossy.
Heat a lightly greased skillet over medium-low heat. Cook the pancakes in small portions until bubbles form across the surface.
Flip and cook for 1 to 2 minutes more, keeping the centers soft and tender.
Stack the pancakes with Greek yogurt and raspberry sauce. Finish with dark chocolate chips.
