Blend the cottage cheese, eggs, milk, and vanilla extract until smooth and creamy.
In a bowl, whisk together the oat flour, protein powder, graham cracker crumbs, cocoa powder, baking powder, and salt.
Stir the blended cottage cheese mixture into the dry ingredients. Fold in the mini chocolate chips and let the batter stand for 5 minutes.
Heat a lightly buttered nonstick skillet over medium-low heat. Cook the pancakes in 1/4 cup portions until bubbles appear and the bottoms are set.
Flip each pancake and cook for another 1 to 2 minutes. Keep the cooked pancakes warm while finishing the batch.
Spread marshmallow creme over the top pancake and spoon the chocolate sauce over the stack.
Finish the s'mores pancakes with crushed graham crackers and extra mini chocolate chips.
