A warm, comforting baked oatmeal that combines the flavors of banana bread with the wholesome goodness of oats and toasted walnuts. Perfect for cozy mornings and easy to prepare with simple ingredients.

Ingredients

Scale
  • 2 cups rolled oats (160g)
  • 3 medium ripe bananas, mashed
  • 1 ¾ cups milk (415ml) – dairy or plant-based
  • ¼ cup maple syrup or honey (60ml)
  • 1 teaspoon vanilla extract
  • 1 teaspoon cinnamon
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • ¾ cup toasted walnuts, chopped (75g)
  • Optional add-ins: chocolate chips, chia seeds, ground nutmeg

Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8 inch (20×20 cm) baking dish lightly with butter or non-stick spray.
  2. Toast the walnuts in a dry skillet over medium heat for about 5 minutes until fragrant and golden. Set aside to cool.
  3. Mash the ripe bananas in a large mixing bowl with a fork until mostly smooth with some small lumps.
  4. Add the milk, maple syrup (or honey), and vanilla extract to the mashed bananas and whisk until combined.
  5. In a separate bowl, stir together the rolled oats, cinnamon, baking powder, and salt.
  6. Pour the dry mixture into the wet banana mixture and stir gently until all oats are moistened. Do not overmix.
  7. Fold in the toasted walnuts, reserving a small handful for topping.
  8. Transfer the mixture to the prepared baking dish and smooth the top. Sprinkle the reserved walnuts evenly on top.
  9. Bake for 35 to 40 minutes until the top is golden brown and the oatmeal is set but slightly soft in the center. A toothpick inserted should come out mostly clean with a few moist crumbs.
  10. Let cool for about 5 minutes before slicing and serving.

Notes

If the top browns too quickly, cover loosely with foil halfway through baking. Use ripe bananas for best flavor. Toast walnuts separately for enhanced crunch and flavor. Do not overmix the batter to keep a tender texture. The baked oatmeal can be prepared the night before and baked fresh in the morning.
