Blend the cottage cheese, vanilla extract, honey, egg whites, oats, cinnamon and baking powder in blender. Heat a griddle or a nonstick pan to medium-low; spray with cooking spray. Pour approximately 1/4 cup batter for each pancake onto the heated surface. When the pancake bubbles, flip it over and cook the other side. Top with a sprinkle of powdered sugar and berries before serving.
