Sounds decadent, but this chocolate baked oatmeal with peanut butter is loaded with healthy ingredients. Of course, it’s still absolutely delicious and so easy to whip up.

I shared a variation of this chocolate baked oatmeal on Instagram and it was such a hit, I knew I had to make a version to share on the blog! My birthday, Valentine’s Day and Galentine’s Day land in this month so I figured now was the perfect time! I would love to wake up to this on my birthday (hint, hint, Isaac!) and also think it would be so fun to serve at a Galentine’s Day brunch.

How to Make Baked Oatmeal with Chocolate

One of the reasons baked oatmeal is so popular is because baked oatmeal recipes are so easy to whip up and perfect for meal prep! You literally need one bowl and one baking dish. Anytime I can cut back on dishes, I’m going to! We do wayyyy too many dishes around here to be adding more mixing bowls, especially now that we have a baby. From pump parts to bottles… it seems like our sink is always fill with dishes.

Mixing bowl with ingredients for chocolate peanut butter baked oatmeal.

To make this baked oatmeal, you start by mixing together the rolled oats, almond milk, cocoa powder, maple syrup, baking powder, sea salt, flaxseed, mashed banana, coconut oil, peanut butter, vanilla in a large bowl. Once that’s combined, add in your chopped chocolate.

Pour the oatmeal mixture into a baking dish that has been sprayed with cooking spray and spread remaining chocolate pieces on top. Then, you’ll just bake until the oatmeal has set. Remove from the oven and let cool for a few minutes and then drizzle peanut butter on top and serve!

Baked Oatmeal Dietary Swaps

I get a lot of questions about ingredient swaps for certain recipes so I thought I would share some easy swaps here if you’re trying to adapt the recipe to follow a certain diet.

  • Oats – be sure you use certified gluten-free oats if you need the recipe to be gluten-free.
  • Almond milk – you can actually use any type of milk in place of the almond milk. Regular dairy milk or another plant-based option will work.
  • Peanut butter – as you know, I love the combination of peanut butter + chocolate, but if you have a nut allergy or prefer a different seed or nut butter, feel free to swap!
  • Chocolate – if you’re looking to keep this recipe vegan or dairy-free, be sure to use vegan chocolate. I like using the Lily’s chocolate, which is sweetened with stevia and lower in sugar.
  • Flaxseed – if you don’t have flaxseed on hand, you can use an egg instead or omit the flaxseed altogether.

Can You Make Baked Oatmeal Ahead of Time?

Yes, you can totally make baked oatmeal ahead of time. Here’s what I recommend:

Option 1: Bake and Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance.
  2. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

Chocolate Baked Oatmeal Serving Suggestions:

Like I said, this would be the perfect baked oatmeal for a brunch! But what do you serve with chocolate baked oatmeal?!

  • Yogurt parfaits – could have them pre-made in little mason jars or it could be fun to have a build-your-own yogurt parfait bar!
  • Breakfast meat – can’t go wrong with breakfast meat at a brunch. Bacon or sausage would love lovely or try tempeh bacon for your vegan friends!
  • Fruit salad or fruit kabobs – every brunch needs fruit!
  • Fun drinks – I feel like drinks can really elevate the brunch! Serve fresh squeezed juices, mimosas and/or fun coffee drinks.

      Superb. This is a hit for the whole family here in the UK. It’s so lovely to find a baked oat recipe that the whole family can enjoy.

      I don’t add the coconut oil though as we are WFPB with SOS (i.e. virtually no processed oil, virtually no salt and virtually no refined processed sugar) and this came out beautifully.

      I shall definitely encourage others to give it a go.

      Delicious and creamy. Great chocolate flavor and it’s healthful! I didn’t have coconut oil so used avocado oil instead and it turned out great.

      Great recipe! My boyfriend was looking a bit suspicious when I took it out of the oven and served it instead of his regular bowl of overnight oats, but he enjoyed it so much that he took two portions and asks for it for desert in the evening! Will also try out the blueberry version.

      Thank made this with a few alterations to amp up the protein. I omitted the maple syrup and added chocolate collagen protein powder which I find to be sweet tasting. I also realized I was out of banana so I used applesauce in place of it. I also used dark chocolate chips. The recipe worked great! I should have left the maple syrup in because it wasn’t sweet enough even with the protein powder’s sweetness but I addressed that by drizzling the 5 ingredient Hershey’s chocolate syrup! You could totally do maple syrup drizzle too. Yum!

      These. Are. AMAZING!!!!!!!!!
      If you were debating making them, MAKE THEM!!!
      I used 1and 1/2 cups of almond milk instead of 2.
      Then I poured half of the batter in the pan, added a layer of peanut butter & chocolate chips, and then the other half of the batter. A-MAZ-ING!!!

      Can’t stop eating it! The flavor is so rich and luxurious – sweet but not too sweet. I knew this was going to be a win the instant I saw the combination of chocolate, peanut butter, and oatmeal. I used only 1 1/2 cups of milk because I’ve found in these recipes that if I use 2 cups, it doesn’t bake all the way through, and it worked perfectly. For the topping, I mixed peanut butter and melted coconut oil to make it nice and drizzley. Would heating up the peanut butter have the same effect?

      1. Brittany Mullins
        March 9, 2021 AT 11:30 pm

        Woo!! So glad you loved this recipe, Madeline. I’ve definitely done that before with my peanut butter and it worked wonderfully. It should be fine to heat the pb in the microwave, but you’ll want to make sure you heat it in small increments of time stirring in between so the pb doesn’t get scorched.

      Can you use regular canola oil instead of coconut oil?

      1. Brittany Mullins
        March 10, 2021 AT 12:02 am

        Yes, that should be just fine!

      Alright, I’ve been making one of your baked oatmeal recipes every week for about three months now and just now got around to trying this recipe after watching your Instagram live. WHAT WAS I THINKING?! WHY DID I WAIT SO LONG TO TRY THESE?! These baked oats are insanely good. They really do just taste like brownies; so much so that I almost feel guilty eating them for breakfast. Almost.

      Is there a swap for the banana? I am not a banana fan. Would applesauce work?

        Yes, you can use applesauce!
