Preheat your oven to 350 degrees F and generously spray a 9x13 baking dish with cooking spray.
Start by mashing the bananas well, then add in the oats, chia seeds, cinnamon, milk, egg whites, and almond extract.
Give it a good stir, then sprinkle the frozen berries on top. Pop it in the oven and bake for 30-35 minutes, or until the liquid is absorbed.
Once it's done, take it out, serve with yogurt, and dig in! Enjoy every spoonful of this delightful dish!
