Preheat oven to 375 F.
In a bowl, mash up the bananas. Then add in all the wet ingredients: almond milk, vanilla extract, and maple syrup.
In another bowl, you can mix all the dry ingredients: rolled oats, quick oats, cinnamon, lemon zest, salt, and baking powder.
Combine the wet and dry ingredients together. Fold in the blueberries.
Spray the baking dish with oil spray and then add in the oats mixture. You can top with more frozen blueberries if you like.
Bake in the oven for 30-35 minutes or until fully cooked.
Once cooked, allow the oats to cool for a few minutes if you like to eat it warm or serve when completely cooked down. Top with fresh fruits if desired or cool whip.
