A cozy, creamy baked oatmeal recipe combining peanut butter and ripe bananas for a warm, comforting breakfast that’s easy to prepare the night before.

Ingredients

Scale
  • 1 1/2 cups old-fashioned rolled oats (135 g)
  • 2 medium ripe bananas, mashed
  • 1/2 cup creamy peanut butter (130 g)
  • 2 cups milk (dairy or plant-based, 480 ml)
  • 2 tablespoons honey or maple syrup (optional)
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking powder
  • Pinch of salt
  • 1/2 teaspoon cinnamon (optional)
  • 1/4 cup chopped nuts or chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Mash the ripe bananas in a large bowl using a fork or potato masher until mostly smooth with a few small lumps left (about 1-2 minutes).
  3. Stir in the peanut butter while the bananas are still warm-ish from mashing.
  4. Add milk, honey or maple syrup (if using), and vanilla extract to the banana-peanut butter mixture. Whisk gently to combine.
  5. In a separate bowl, combine rolled oats, baking powder, salt, and cinnamon. Mix well.
  6. Pour the wet mixture into the dry ingredients bowl and stir gently until just combined, about 1 minute.
  7. Lightly grease your baking dish with butter or oil, then pour the oatmeal mixture in, spreading evenly.
  8. Drop spoonfuls of peanut butter on top and use a knife or skewer to swirl them into the oats.
  9. Optionally, sprinkle chopped nuts or chocolate chips on top.
  10. Cover the dish loosely with foil or a lid and bake for 25-30 minutes, until edges are golden and center is just set but still creamy.
  11. Remove from oven and let rest for 5 minutes before serving.

Notes

Use old-fashioned rolled oats for best texture; avoid instant oats. If bananas are not ripe enough, add a teaspoon of brown sugar or honey. To prevent sticking, grease the baking dish lightly. If top browns too quickly, cover with foil halfway through baking. For vegan version, use plant-based milk and maple syrup instead of honey. Protein powder can be added but keep liquid amount the same. Leftovers store well in fridge up to 3 days and can be frozen for up to 2 months.
