Ingredients

  • 1 large spotty banana mashed
  • ½ cup creamy all-natural peanut butter one that is runny
  • 3 tablespoon real maple syrup or honey
  • 1 ¾ cups of unsweetened almond milk or oat milk
  • 1 large egg or 1 tablespoon ground flaxseed with 3 tablespoon of warm water (for vegan option)
  • 2 teaspoon vanilla extract
  • 2 cups old-fashioned rolled oats (200g)
  • 1 teaspoon ground cinnamon
  • 1 teaspoon baking powder
  • ½ teaspoon salt

Instructions

    Cup of Yum
  1. Preheat: Preheat your oven to 350°F (175°C). Lightly grease a 9-inch square dish with cooking spray or avocado oil.
  2. Mix Wet Ingredients: In a large bowl, combine the mashed banana, peanut butter, maple syrup, milk, egg (or omit for a vegan option), and vanilla extract. Whisk until fully combined.
  3. Add Dry Ingredients: Stir in the rolled oats, cinnamon, baking powder, salt, and ground flaxseed (if not using an egg). Mix until all ingredients are well incorporated. All peanut butter brands are different, so make sure your batter is not too stiff. If you use a thicker peanut butter, you may need to add a dash more milk. Look at the reference picture below to compare.
  4. Pour: Pour the mixture into the greased baking dish, spreading it evenly.
  5. Bake: Bake for 35 to 45 minutes, until the top is golden brown and the center is set.
  6. Serve: Allow the baked oatmeal to cool for 5 minutes before serving. Optionally, drizzle with extra peanut butter and garnish with banana slices. Enjoy your delicious peanut butter baked oatmeal!

Notes

  • Batter Notes: This batter is "wetter" than typical baked oatmeal recipes. It's super moist, fluffy, and soft when baked, so don't be alarmed.
  • Banana Ripeness: Ensure your banana is spotty and ripe for maximum sweetness and flavor in the baked oatmeal.
  • Peanut Butter Consistency: Opt for an all-natural creamy, runny peanut butter for a smooth texture. If your peanut butter is thick, consider gently heating it to make it easier to mix.
  • Peanut Butter Sub: Any other nut or seed butter, such as almond butter, cashew butter, or sunflower seed butter, can be used as a substitute for peanut butter. Make sure it is creamy and well-stirred.
  • Almond Milk or Oat Milk: Any other milk alternative, such as soy milk, coconut milk, or cow’s milk, can be used depending on your dietary preferences and availability.
  • Rolled Oats: Quick oats can be used instead of rolled oats in this recipe. However, they may have a slightly different texture compared to rolled oats.
  • Freezing: You can freeze baked oatmeal. Allow it to cool completely, then cut it into individual servings and wrap them tightly in plastic wrap or aluminum foil. Place the wrapped portions in a freezer-safe bag or container and freeze for up to 2-3 months. To reheat, thaw overnight in the refrigerator or microwave from frozen until heated through.
  • Storing: Allow the baked oatmeal to cool completely after baking. Once cooled, transfer any leftovers to an airtight container. Make sure the container is sealed well to prevent moisture from getting in. Store the container in the refrigerator for up to 3-4 days.
  • Reheating: To reheat peanut butter baked oatmeal, simply place individual portions in the microwave on high for 1-2 minutes until heated through. Alternatively, reheat larger portions in the oven at 350°F (175°C) for 10-15 minutes, covered with foil to prevent drying out.
