The Cooking Process Explained
Making Peanut Butter Banana Baked Oatmeal is as enjoyable as eating it. The cooking process flows seamlessly from mashing the banana to whisking wet ingredients, mixing in the oats and spices, and finally baking it to perfection. With just a few simple steps, you’ll have a hearty dish ready to serve to family and friends.
Gather These Items
Here’s everything you’ll need to create this scrumptious baked oatmeal:
- 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
For those with nut allergies, you can substitute the peanut butter with sun butter or tahini, and if you prefer a vegan version, the flaxseed option works beautifully!

Directions to Follow
- Preheat your oven to 350°F (175°C) and 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 in the oats, cinnamon, baking powder, and salt. Stir until evenly mixed. If the mixture feels too thick, feel free to add a splash more milk until it reaches your desired consistency.
- Pour the mixture into the prepared baking dish, spreading it out 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 toss in some sliced bananas if desired. Enjoy!
Best Ways to Enjoy It
This baked oatmeal is best served warm straight from the oven. Consider drizzling a bit of extra peanut butter on top or adding a sprinkle of chopped nuts for a delightful crunch. You can also pair it with fresh fruit, yogurt, or a drizzle of honey for an added touch. A steaming cup of coffee or tea complements this dish perfectly, making for a delightful morning experience.
Storage and Reheating Tips
If you happen to have leftovers, store them in an airtight container in the fridge for up to 5 days. They reheat beautifully in the microwave—just warm each serving for about 30-60 seconds. You can also enjoy it cold, straight from the fridge, as a nutritious snack!
Helpful Cooking Tips
To make your baked oatmeal even more decadent, try letting the dish sit for a few minutes after baking. This will help it set a bit more, leading to beautifully firm slices. If oats aren’t your thing, consider substituting quinoa or cooked rice for a unique twist. Keep in mind that using a ripe, spotty banana is key; the more spots, the sweeter the final dish will be!
Recipe Variations
Feel free to switch things up with this versatile recipe! You can add mix-ins like chocolate chips, dried fruits, or nuts to enhance the texture and flavor. Try using almond butter instead of peanut butter for a different nutty flavor, or swap in blueberries for a fruity punch. You can also add spices like nutmeg or even a hint of cocoa powder for a chocolatey version!
