Ingredients

Scale

Wet Ingredients

  • 1 large spotty banana (mashed)
  • ½ cup creamy all-natural peanut butter (one that is runny)
  • 3 tbsp real maple syrup or honey
  • 1 ¾ cups unsweetened almond milk or oat milk
  • 1 large egg (or 1 tbsp ground flaxseed mixed with 3 tbsp warm water for vegan option)
  • 2 tsp vanilla extract

Dry Ingredients

  • 2 cups old-fashioned rolled oats (200g)
  • 1 tsp ground cinnamon
  • 1 tsp baking powder
  • ½ tsp salt

Instructions

  1. Preheat: Preheat your oven to 350°F (175°C). Lightly grease a 9-inch square baking dish with cooking spray or avocado oil to prevent sticking.
  2. Mix Wet Ingredients: In a large bowl, combine the mashed spotty banana, creamy peanut butter, maple syrup (or honey), unsweetened almond or oat milk, egg (or flaxseed mixture for vegan), and vanilla extract. Whisk these ingredients thoroughly until you obtain a smooth, fully combined mixture.
  3. Add Dry Ingredients: Stir in the rolled oats, ground cinnamon, baking powder, salt, and ground flaxseed (only if you are not using an egg) into the wet ingredients. Mix well to ensure all components are evenly incorporated. Depending on the thickness of your peanut butter, you may need to add a little more milk if the batter is too stiff. The batter should be moist but not overly runny.
  4. Pour: Transfer the prepared batter into the greased baking dish, spreading it out evenly with a spatula to create a uniform layer.
  5. Bake: Place the dish in the preheated oven and bake for 35 to 45 minutes. Bake until the top turns golden brown and the center is set, indicating it is fully cooked through.
  6. Serve: Remove from the oven and let the baked oatmeal cool for about 5 minutes before serving. For extra indulgence, optionally drizzle with additional peanut butter and garnish with fresh banana slices. Serve warm and enjoy!

Notes

  • You can substitute honey for maple syrup if preferred but note this is not vegan.
  • Use old-fashioned rolled oats for the best texture; quick oats may result in a mushier bake.
  • The flaxseed egg replacement works great for a vegan alternative and also adds fiber.
  • If your peanut butter is very thick, adjust the milk amount to get a batter consistency similar to the reference photo.
  • This baked oatmeal can be stored in the fridge for up to 4 days or frozen for longer storage.
  • Reheat portions in the microwave for about 30-60 seconds before serving.
