  • Bananas: Ripe bananas give this pb banana oat bake recipe delicious flavor, along with added fiber and nutrients.
  • Peanut Butter: Use creamy or crunchy peanut butter depending on your preference! I recommend going with a natural peanut butter that contains only peanuts.

  • Rolled Oats: Rolled oats, or old fashioned oats, give the perfect texture for this healthy baked oatmeal!
  • Baking Powder: This peanut butter baked oatmeal with banana will rise and fluff in the oven thanks to baking powder.
  • Cinnamon: Add a sprinkle of cinnamon to elevate taste and aid in balancing blood sugar. This warm spice is comforting and pairs well with peanut butter and bananas.
  • Maple Syrup: This is optional, but you can sweeten baked peanut butter oats with a little bit of pure maple syrup!

🍲 Ingredient Substitutions

  • Milk: Any milk will work in this oats recipe. Try it out with other non-dairy milk options like oat milk or coconut milk. If you are not vegan or dairy-free, regular milk is fine too.
  • Sugar: Try this healthy peanut butter oatmeal bake with maple syrup substitutes like brown sugar or white sugar. To keep this hearty breakfast refined sugar free, use coconut sugar or raw honey.
  • Nut Butter: If you do not like peanut butter or have a peanut allergy, try this baked oatmeal with almond butter instead!
  • Different Oats: If you prefer, you can use other types of oats like quick oats. Steel cut oats won’t work as well in this pb banana breakfast bake.

If this is your first time making baked peanut butter oatmeal, don’t stress! This quick breakfast is so easy to make and you can follow along step by step.

Here is how to make the best peanut butter banana baked oatmeal recipe:

Preheat Oven, Mix Wet Ingredients: Preheat the oven to 350 degrees F / 180 C. Spray a 8×8 baking dish with spray oil. In a large mixing bowl, whisk the almond milk, vanilla extract, maple syrup, mashed bananas, peanut butter. Add the egg and whisk until smooth.

Remove and allow the baked oatmeal with bananas to cool and set for 20-25 minutes before slicing and serving. Serve topped with whipped coconut cream, banana slices, a drizzle of maple syrup or toasted almonds.

💭 Expert Tips

  • Use Overripe Bananas: For a boost of natural sweetness use overripe bananas.
  • Avoid Sticking: Be sure to grease your pan to prevent the baked oatmeal from sticking. I like to use cooking spray or coconut oil.
  • Make Individual Portions: If you want to make this baked banana peanut butter oatmeal into a pre-portioned grab and go breakfast, evenly disperse the mixture into a lined muffin tin. You will be all set the next morning!
  • Consistency: If your mixture seems too thick, add a little milk to thin it out. If you want a more blended, creamy texture use oat flour instead of whole oats.

📖 Variations 

  • Chocolate Peanut Butter And Banana Oatmeal Bake: Mix in some cocoa powder or cacao powder, along with dark chocolate chips for the most delicious chocolate variation. You can also try out this chocolate chip baked oats recipe.
  • Salted Baked Oatmeal: Sprinkle sea salt on top of your baked oatmeal for the perfect touch of sweet and salty!
  • PB Baked Oatmeal With No Sugar: Just omit the maple syrup for a completely sugar free option!
  • More Protein: This pb and banana oatmeal bake is already packed with protein but add even more with some protein powder. Go with 1-2 scoops of unflavored or vanilla protein powder to keep the taste similar to the original recipe. Adding a dollop of Greek yogurt on top is another great way to boost protein content.

🍽 Serving Suggestions

Serve this pb banana oat breakfast bake on a plate with a drizzle of peanut butter and fresh fruit like sliced bananas, caramelized bananas, or fresh berries. For a sweet breakfast or dessert, pair with ice cream, drizzle with vegan nutella, or top with a crumble of your favorite cookies. I also love this as a cozy treat after dinner with warm milk.

🙌 Dietary Adaptations

This healthy banana oatmeal bake can be easily modified for dietary needs and personal preference. 

Vegan Banana Baked Oatmeal: To make this vegan-friendly, substitute the egg for 1 flax egg (1 tbsp ground flax seeds and 3 tbsp water mixed together to form a paste.) You could also use ground chia seeds for the same result!

Nut-Free Option: If you have a nut allergy, skip the peanut butter and try this easy baked oatmeal recipe with sunflower seed butter!

Here is how to store and keep this healthy baked banana oatmeal:

To Store in the Fridge: Let your leftover peanut butter baked oatmeal cool to room temperature. Transfer to an airtight container or cover pan securely with plastic wrap. This oatmeal can be stored in the fridge for up to 5 days.

To Reheat: You can enjoy this healthy baked oatmeal recipe cold or hot. If you would like to reheat, microwave for 20 seconds or bake in the toaster oven.

❓Recipe FAQs

IS ADDING PEANUT BUTTER TO OATMEAL HEALTHY?

Adding peanut butter to oatmeal is a great way to get in additional protein and healthy fats. Peanut butter helps to create a well-rounded, balanced meal that won’t spike your blood sugar as much. It is filling, hearty, and satisfying. I recommend sticking with an organic peanut butter that contains only nuts. Some brands are full of sugar which delivers a sweet peanut butter that tastes great but is not great for you.

ARE BAKED OATS HEALTHY FOR YOU?

Yes! In general baked oats are very healthy, but you do have to keep an eye out for some recipes that add a ton of refined sugar and processed ingredients. Luckily this peanut butter banana baked oats is made with clean ingredients and avoids processed sugar. For the healthiest baked oats, opt for an unsweetened almond milk with limited ingredients, pure maple syrup, and organic rolled oats. With each serving you will get in a great amount of protein and dietary fiber.

WHAT’S THE DIFFERENCE BETWEEN BAKED OATS AND OATMEAL?

While oatmeal is cooked on the stove top or microwave, baked oats are mixed together with other ingredients and placed in the oven to bake. Oatmeal can vary from runny to thick, but ultimately is more of a porridge consistency. With a healthy baked oats recipe like this pb banana oatmeal bake, you have a more solid consistency similar to quick bread or oatmeal cookies.
