Why oats and bananas make a breakfast winner
Oats bring slow-release energy and soluble fiber. Bananas add natural sweetness, potassium, and a creamy texture.
Combining them in a baked bar creates a filling breakfast that feels indulgent.
Step-by-step baking directions
- Preheat oven to 350°F. Grease and flour an 8 x 8-inch baking pan, or line it with parchment.
- Mix the topping: combine 2/3 cup oats, 2/3 cup coconut, 1/3 cup brown sugar, and 1/2 teaspoon cinnamon in a bowl.
- Pour in 1/4 cup melted butter and stir until the topping is crumbly. Set aside.
- Whisk dry cake ingredients: 1 1/3 cups oats, 3/4 cup flour, 3/4 teaspoon baking powder, 1/2 teaspoon baking soda, 1/4 teaspoon salt, and 1 teaspoon cinnamon.
- Cream 1/2 cup softened butter with 2/3 cup brown sugar until lighter in color and fluffy.
- Add the eggs, 1 1/2 teaspoons vanilla, and the mashed bananas. Mix until combined.
- On low speed, fold the dry mixture into the wet ingredients just until incorporated. Stir in 1/3 cup chocolate chips.
- Spread the batter evenly in the prepared pan. Sprinkle the oat-coconut topping across the surface. Add a few extra chocolate chips if you like.
- Bake for 40–45 minutes, until a toothpick in the center comes out clean or with a few moist crumbs.
- Allow the cake to cool slightly before cutting into bars. Serve warm or room temperature.
