The Cooking Process Explained
Making Peanut Butter Banana Baked Oatmeal is a breeze! You’ll start by mashing the bananas and mixing them with your wet ingredients. Then, it’s a simple matter of combining everything with oats and spices before baking it to golden perfection. In just a few steps, you’ll have a delicious dish ready to enjoy.
What You’ll Need
Gather these items for a tasty baking experience:
- 1 large spotty banana (mashed)
- ½ cup creamy all-natural peanut butter
- 3 tbsp real maple syrup (or honey)
- 1 ¾ cups 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
- 1 tsp ground cinnamon
- 1 tsp baking powder
- ½ tsp salt
Note: If you’re looking for alternatives, almond butter works well instead of peanut butter, and you can swap out the oats for gluten-free options if needed.

Directions to Follow
- Preheat your oven to 350°F (175°C). Lightly grease a 9-inch square baking dish.
- In a large bowl, mash the banana until smooth.
- Whisk in the peanut butter, maple syrup, almond milk, egg (or flaxseed mixture), and vanilla extract until well combined.
- Gradually add the oats, cinnamon, baking powder, and salt. Stir until evenly mixed; if the mixture is too thick, add a splash more milk to reach your desired consistency.
- Pour the mixture into the prepared baking dish, spreading it evenly.
- Bake for 35 to 45 minutes, or until the top is golden and the center is set.
- Allow it to cool for 5 minutes before slicing. For a fun finishing touch, drizzle with extra peanut butter and add sliced bananas if desired. Enjoy!
Best Ways to Enjoy It
This baked oatmeal is delicious on its own, but you can elevate your serving game! Try adding fresh fruit on top—berries, apple slices, or more bananas work beautifully.

Tips to Make It Perfect
