Easy Banana Baked Oatmeal with Peanut Butter and Chocolate Chips

Who doesn’t love the classic combination of peanut butter, banana, and chocolate chips baked into an ooey-gooey, fiber-rich breakfast?

This Peanut Butter, Banana, Chocolate Chip Baked Oatmeal is one of our (and yours) favorite baked oatmeal combinations based on our popular oatmeal cups.

This oatmeal bake is a dairy-free and gluten-free breakfast packed with healthy ingredients but tastes like dessert! It’s a simple, one-bowl recipe that is delicious straight from the oven or stored for meal prep. Whip this baked oatmeal recipe up at the beginning of a busy week and have breakfasts or snacks on hand all week long (or keep it in the freezer for even longer)!

Reader Review
“Great! Easy to make, already have ingredients. I've tried other oatmeal bakes from other sites and they tend to come out dry or just not the right texture. This one was exactly what I was hoping for! Great flavor and texture. My daughter loved it too!”

Are Baked Oats Good for You?

Absolutely! This baked oatmeal recipe is a delicious and nutritious way to start your day. It’s packed with protein from the eggs and nut butter, fiber from the oats and chia seeds, and much more, thanks to an array of healthy ingredients.

Ingredients Needed

  • Bananas – Be sure to use ripe bananas for extra sweetness. Bananas that still have green on them will be chalkier and less sweet.
  • Eggs – Egg adds a good protein boost and helps bind everything together.
  • Peanut Butter – Use your favorite variety of creamy peanut butter. Alternatively, swap that out for any nut butter you prefer.
  • Maple Syrup – My natural sweetener of choice. If you don’t have maple syrup, honey will also work.
  • Milk – I like to use almond milk, but use any milk you have on hand.
  • Oil – You can use melted avocado or coconut oil for richness and moisture.
  • Applesauce – Applesauce provides this baked oatmeal recipe with additional sweetness and acts as another binder.
  • Vanilla Extract – Adds flavor depth.
  • Oats – Use rolled oats, NOT quick-cooking oats. If you’re gluten-free, make sure that you buy certified gluten-free rolled oats.
  • Baking Powder – A little baking powder prevents the oatmeal bake from being too dense.
  • Chia Seeds – These are optional but a great way to add extra fiber and healthy fats.
  • Sea Salt – A sprinkle of fine sea salt helps bring out all of the flavors in your oatmeal bake recipe.
  • Chocolate Chips – I use enjoy life dark chocolate chips—regular or mini. Feel free to use whatever variety of chocolate chips you prefer.

How to Make an Oatmeal Bake

This baked oatmeal recipe is as simple as it gets! It takes just a few minutes to prep, then it’s in the oven. Here’s a quick rundown of the recipe:

  1. Combine the wet ingredients: In a large bowl, mash the bananas until smooth, then whisk in the eggs. Once combined, stir in the peanut butter, maple syrup, almond milk, oil, applesauce, and vanilla.
  2. Add the dry ingredients: Oats, baking powder, chia seeds, salt, and chocolate chips, then mix until everything is well-distributed.
  3. Bake: Transfer the oatmeal mixture to a greased baking dish lined with a parchment sling. Bake at 350ºF until the center is just firm. Cool slightly, then scoop or cut and serve!

Can You Bake Instant Oatmeal?

I don’t recommend it. Instant oats are different than regular because they are thinly cut, processed, and often flavored. That doesn’t lend the same structure to baked goods or baked oatmeal as regular or quick oats.

Can Baked Oatmeal Be Made Without Eggs?

Yes! Baked oats do require a binder, though, so if you need to make yours without an egg you will need to use an alternative.

Egg Alternative!

A great option is to substitute your regular egg for a flax egg (1 tablespoon of flaxseed meal and 3 tablespoons of water.) To make the two flax eggs needed for this recipe, combine 2 tablespoons of flaxseed meal and 6 tablespoons of water. Once mixed, allow the flax egg to sit for a few minutes, then add it to the oat mixture as directed.

Why Are My Baked Oats Soggy?

There may be a couple of reasons that your baked oats are soggier than you want them to be:

  • You used quick oats. While it is possible to use rolled oats or quick oats, I do recommend the rolled oats for this recipe. They have more structure than quick oats for a heartier, chewier texture.
  • You didn’t accurately measure your ingredients. Ensure you measure your wet and dry ingredients precisely so you have the perfect ratio to result in the perfect texture.
  • They need more time to bake. Sometimes, soggy baked oats need a little more time in the oven!

Tips and Notes

  • Grease the baking dish. Be sure to grease your baking dish with a light coating of cooking spray before you add the oatmeal mixture. This prevents it from sticking to the pan.
  • Line with a parchment sling. A parchment sling is optional, but it does make it easier to lift the oatmeal bake out of the pan once it’s done baking.
  • Check for doneness. The best way to ensure your oatmeal bake is done is to insert a toothpick into the center. If it comes out clean, then the banana-baked oatmeal is ready. If it comes out with any “batter” still on it, the bake needs more time.
  • Cool slightly before slicing. I recommend letting the oatmeal bake sit in the pan for a few minutes before you slice into it. This gives it time to finish setting up (and prevents you from burning your mouth on hot oats!)


  • Use another nut butter. Feel free to swap the peanut out for almond or cashew butter if preferred.
  • Make it nut-free. Looking for a nut-free option? Try it with sun butter instead.
  • Add fruit. Add more texture by tossing in a handful of fresh or frozen raspberries or blueberries. Alternatively, add some chewy sweetness with a handful of dried cranberries or raisins.
  • Use other mix-ins. Looking for even more textures? Try stirring in chopped nuts, coconut flakes, flax seeds, or pumpkin seeds.
  • Spice it up. Add some extra flavor with a sprinkle of cinnamon or nutmeg.

Serving Suggestions

I love to serve a slice of this baked oatmeal warm out of the pan with a bit of almond milk! It’s also tasty when cooled and sliced into portions for a tasty grab-and-go breakfast or snack.

If you’re serving it as a sit-down breakfast, here are some delicious pairing options:

How to Store

Leftover oatmeal bake can be stored in an airtight container in the fridge for up to 4 days or in the freezer for up to 3 months.

Before reheating, defrost overnight, in the fridge, if frozen or give it a quick pass in the toaster oven or microwave to heat up.

To warm single slices: Heat in the toaster oven or oven at 350ºF for 5-10 minutes or microwave for a minute or until heated through.

To warm the whole tray: Heat in the oven at 350ºF for 20 minutes or until heated through.

    Great recipe! I used almond butter, doubled the chia seeds and added 1/2 cup of chopped frozen organic berries.

  2. Can this be made without the eggs? All other ingredients, including the Enjoy Life Chocolate is vegan friendly 🙂

  3. 5 stars
    This is amazing! What’s the best way to reheat in the morning? I just baked it this evening and want to serve it in the morning. Can I pop it into the oven for a few minutes to reheat or will it dry out? Thanks!

  4. 5 stars
    This was such a hit with my family. My kids love it and my husband as welll, plus it freezes really well. My kids were tired of eating eggs for breakfast every morning and they don’t normally eat oatmeal but they will eat this up!

  5. I know you teach us Lexi to live Gluten Free and Dairy Free, but I also thought your eating plans were Paleo. I did not know we could have oatmeal on paleo. just asking.

  6. 5 stars
    Just pulled these out of the oven and they smell AMAZING!! Thanks for creating another fantastic easy recipe. Just like the commented above, I had everything in my pantry. It’s the best!

  7. 5 stars
    Just put this in the oven to have for breakfast this week. It was so easy and I loved that I had everything ready to go in my kitchen since I haven’t been grocery shopping yet. Another hit!

  8. 5 stars
    Made these the other day for my hubs to have a grab and go breakfast. They were super easy to make and we loved them! I was even able to find Enjoy Lifes mini chips in my grocery store which was very exciting.

  9. 5 stars
    We love Enjoy Life products. They are so much more than chocolate chips. Your cupboard could be filled with enough snacks to suit any taste.

  10. Ooh, I happen to have all of these ingredients (including Enjoy Life mini chips, which I may or may not eat straight from the bag). I’m so making these soon!
