Birthday-Cake Baked Oats

Preheat oven to 400°F. Place oats, brown sugar, baking powder, milk, 2 tablespoons yogurt and vanilla in a small blender or mini food processor. Blend until the oats are finely chopped.

Coat 3 silicone or paper muffin cups (placed in a standard muffin tin) or a 6-ounce oven-safe ramekin or baking dish with cooking spray. Pour the batter into the cups or ramekin. With your fingers, sprinkle 1/2 teaspoon rainbow sprinkles evenly over the batter.

Bake until domed and golden brown, about 15 minutes (if using muffin cups) or 20 minutes (if using a ramekin). While the oats bake, whisk the remaining 1 tablespoon yogurt with honey to make frosting.

Let the oats cool slightly, then top with the yogurt frosting and remaining sprinkles.
