Method
- Prepare the oven and pan: Preheat your oven to 350°F (175°C). Lightly grease an 8x8-inch baking dish.
- Mash the bananas: In a large bowl, mash the bananas until smooth. The riper the bananas, the sweeter the oatmeal will be.
- Mix the wet ingredients: Whisk in the brown sugar, eggs, salt, and vanilla extract until combined.
- Add dry ingredients: Stir in the baking powder, cinnamon, and nutmeg.
- Stir in milk and oats: Add the milk and rolled oats, mixing until everything is evenly coated.
- Fold in walnuts: Stir in the chopped walnuts for crunch.
- Bake: Pour the mixture into the prepared dish and bake for 35–40 minutes, until the top is golden and set.
- Cool and serve: Let it cool slightly before slicing. Enjoy warm, at room temperature, or chilled from the fridge.
Notes
- Bananas matter – The riper the bananas, the sweeter the baked oatmeal will be. Spotty bananas work best.
- Oats – Rolled oats give the best chewy texture. Quick oats make it softer, while steel-cut oats won’t cook through in this recipe.
- Sweetness – Adjust the brown sugar based on how sweet your bananas are. For a banana baked oatmeal with no sugar version, rely only on ripe bananas or swap in maple syrup.
- Add-ins – Chocolate chips, raisins, or chopped nuts all work beautifully. For extra protein, stir in a scoop of protein powder or top with peanut butter.
- Serving ideas – I like it warm with a spoonful of Greek yogurt, a drizzle of maple syrup, or fresh fruit on top.
- Storage tip – This recipe keeps well in the fridge for up to 5 days or can be frozen in slices for up to 2 months.
