Prepare the batter. Place the cottage cheese, almond flour, whole egg, egg whites, baking powder, and vanilla extract in a blender. Process until the ingredients form a smooth, evenly blended pancake batter.
Preheat the pan. While preparing the batter, warm a nonstick frying pan over medium heat so the cooking surface is evenly heated and ready for the pancakes.
Cook the first side. Spoon portions of the batter into the hot pan. Allow the pancakes to cook for approximately 2 minutes, or until their undersides become golden brown and the edges appear set.
Flip and finish cooking. Carefully turn each pancake over and continue cooking for about 1 additional minute, until the second side develops a golden color.
Serve. Transfer the finished pancakes to a plate and arrange them in a stack. Garnish with fresh blueberries, if using, and finish with a drizzle of maple syrup.
