Preheat the oven to 375°F. Grease the 8"x 8" pan with cooking flour spray or butter.
Peel ripe bananas over a pan. Then smash until smooth and consistently creamy with a fork. Add egg and mix. Add oatmeal, maple syrup, cinnamon, salt, vanilla extract, milk, and mix everything together.
Add chopped strawberries and mix everything together. Optional- add nuts or chocolate chips on top.
Bake for 45-50 or until the top is golden (if using frozen strawberries, bake for 50-55 min until golden on top). Let cool for 10 minutes before serving.
