This Peanut Butter Banana Baked Oatmeal tastes just like banana bread! Dotted with chocolate chips, it’s chewy, filling, and a great way to start the day.
Baked oatmeal might be one of my new favorite things. I’ve found that even those who don’t love the texture of regular oatmeal or overnight oats love it. The texture is a bit cake-like, thick, and chewy – not mushy or goopy like other oatmeal can be. Baking it really changes the texture! There are endless flavor variations but my favorite is the one I’m sharing today – peanut butter banana baked oatmeal, topped with chocolate chips. Yum!
Why My Family Is Obsessed With This Banana Baked Oatmeal
- Tastes like banana bread. This baked oatmeal recipe is made with many of the same ingredients as my peanut butter banana bread, just swapping the dry ingredients for oatmeal. It has the rich, warm flavors from brown sugar and cinnamon and, of course, the bananas.
- Chocolate & peanut butter too! Incorporating both peanut butter and chocolate chips means that everyone has something to love about this oatmeal.
- Great for meal prep. Baked oatmeal stores very well in both the fridge and freezer. I love to make a batch on the weekend so everyone can heat up a slice during the week for a satisfying breakfast without any effort.
Recipe Ingredients
Here’s an overview of the ingredients used in this recipe. Scroll down to the recipe card below for the exact measurements.
- Bananas – Use bananas that are ripe but not quite overripe (like you’d use for banana bread).
- Peanut butter – I like to use creamy peanut butter. Natural peanut butter and chunky peanut butter would work too.
- Vanilla
- Maple syrup – REAL maple syrup, not pancake syrup! It adds a warm maple flavor that pairs nicely with the banana while sweetening the oatmeal.
- Brown sugar – A small amount of brown sugar adds moisture and sweetens the baked oatmeal.
- Egg – Helps add structure to the oatmeal.
- Milk – Any milk or milk alternative works here, like 2% milk or almond milk.
- Oats – It’s important to use rolled oats in this recipe. Instant oats will be too mushy and steel cut oats are too chewy.
- Baking powder
- Salt – Helps balance the sweet flavors.
- Cinnamon – Adds a bit of warm flavor to the oatmeal.
- Chocolate chips – I used semi-sweet chocolate chips. Peanut butter chips would be another great option.
How To Make Peanut Butter Banana Baked Oatmeal
This breakfast only takes a few minutes of hands-on time to make. The printable instructions are in the recipe card below.
- Prep. Grease the baking dish or line it with parchment paper. Preheat the oven to 350F.
- Make the batter. Combine the mashed banana and peanut butter. Stir in the vanilla, maple syrup, brown sugar, and egg until fully incorporated. Add the milk. Stir in the oats, baking powder, salt, and cinnamon until combined.
- Bake. Transfer the mixture to the baking dish. Top with chocolate chips. Bake for 20-25 minutes, until the edges are starting to brown and the top springs back up when pressed on.
- Enjoy. Cool slightly then slice and serve.
Tips & Variations
Here are a few tips for making banana baked oatmeal, as well as a few ways to customize the dish.
- Use the right oats. Rolled oats are the way to go here. Instant oatmeal (quick oats) will be way too mushy. Steel cut oats are a better option but still end up pretty chewy.
- Skip the chocolate chips. I’m a big fan of chocolate chip banana bread, so naturally I love chocolate chips in my banana baked oatmeal too. But if you’re not a chocolate fan, they can easily be omitted!
- Add some nuts and/or seeds. For some added crunch and flavor, stir chopped walnuts or pecans into the batter. Seeds like ground flaxseed or chia seeds are another great option. Other mix-in options are fresh blueberries or apples.
- Use ripe bananas. The riper the bananas, the sweet the oatmeal and the more flavorful it will be. It’s okay to use bananas that are just starting to brown!
- Dairy-free. Replace the milk with any non-dairy milk like coconut milk, oat milk, cashew milk or almond milk.
Serving Suggestions
I love to enjoy this peanut butter banana baked oatmeal warm and drizzle on melted peanut butter over the top. Honey or maple syrup also works great as a topping, along with additional banana slices.
A larger slice of this baked oatmeal is a great breakfast on its own. Smaller slices make a great addition to a larger breakfast or brunch spread, next to some crispy air fryer bacon and scrambled eggs. A fruit bowl would also make a great side!
How To Store & Reheat Leftovers
- Fridge. Leftover peanut butter banana baked oatmeal stores beautifully in the fridge! Cover the pan tightly with foil or transfer slices to an airtight container. Reheat slices in the microwave for 60-90 seconds. Best enjoyed within 4-5 days.
- Freezer. Let the oatmeal cool completely. Wrap the entire pan tightly in plastic wrap and foil OR cut the oatmeal into slices, wrap each slice individually, and place in a ziploc bag. Thaw in the fridge or on the counter then reheat in the microwave.

Can you freeze leftovers?
Hi Deb. Yes, let the oatmeal cool completely. Wrap the entire pan tightly in plastic wrap and foil OR cut the oatmeal into slices, wrap each slice individually, and place in a ziploc bag. Thaw in the fridge or on the counter then reheat in the microwave.
