Preheat oven to 350° Fahrenheit. Lightly grease the ramekins with cooking spray and set aside.
Add the oats, bananas, eggs, brown sugar, vanilla, cinnamon, baking powder, and salt to the blender. Blend until smooth.
Then pour the mixture evenly into the ramekins.
Next, add your desired toppings to the oat mixture.
Place the ramekins on a baking sheet and transfer to the oven. Bake for 15 to 20 minutes, or until completely cooked-through.
Remove from the oven and serve immediately. Enjoy your new favorite breakfast!
