  • Total Time: 45-55 minutes
  • Yield: 8 servings

Ingredients

Wet Ingredients

  • 1 large spotty banana (mashed)
  • ½ cup creamy all-natural peanut butter (preferably 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 bean paste

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 mixing bowl, combine the mashed banana, creamy peanut butter, maple syrup, almond or oat milk, egg (or flaxseed mixture for vegan version), and vanilla bean paste. Whisk thoroughly until the mixture is smooth and homogenous.
  3. Add Dry Ingredients: Stir in the rolled oats, ground cinnamon, baking powder, salt, and if using, the ground flaxseed mixture to replace the egg. Mix until all ingredients are evenly incorporated. If the batter feels too stiff due to thick peanut butter, add a little more plant-based milk to achieve a batter consistency similar to the reference.
  4. Pour: Pour the oatmeal batter into the prepared baking dish, spreading it evenly with a spatula to ensure uniform thickness.
  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 fully set, indicating it is cooked through.
  6. Serve: Remove from the oven and let it cool for about 5 minutes. Optionally, drizzle extra peanut butter on top and garnish with fresh banana slices before serving. Enjoy warm for a wholesome breakfast treat!

Notes

  • For a vegan version, replace the egg with ground flaxseed mixed with warm water as described.
  • If your peanut butter is thick, add a splash more almond or oat milk to loosen the batter.
  • You can substitute maple syrup with honey if not strictly vegan.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat before serving.
  • Feel free to add toppings like nuts, seeds, or fresh fruit for extra texture and flavor.
