How to Make Peanut Butter Banana Baked Oatmeal
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 of unsweetened almond milk or oat milk
- 1 large egg (or 1 tbsp ground flaxseed with 3 tbsp of warm water for vegan option)
- 2 tsp vanilla extract
- 2 cups old-fashioned rolled oats (200g)
- 1 tsp ground cinnamon
- 1 tsp baking powder
- ½ tsp salt
Directions:
- Preheat: Preheat your oven to 350°F (175°C). Lightly grease a 9-inch square dish with cooking spray or avocado oil.
- 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.
- 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.
- Pour: Pour the mixture into the greased baking dish, spreading it evenly.
- Bake: Bake for 35 to 45 minutes, until the top is golden brown and the center is set.
- 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!
