Preheat oven to 350°F (175°C). Grease a mini muffin tin or line with paper liners.
In a blender, combine cottage cheese, rolled oats, grated apple, egg, cinnamon, baking powder, and vanilla. Blend until smooth.
Spoon batter evenly into mini muffin tin, filling each cup about ¾ full.
Bake 12–15 minutes until set and lightly golden. Cool 5 minutes in tin, then transfer to a wire rack.
