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.
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
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.
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
Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
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.

This was so delish! I modified it a little bit and it still turned out super moist! Put a heaping Tbs. pumpkin in place of coconut oil and not as much syrup. I used whole milk because thats all I had. Thanks for the recipe. I’m wondering if others might be using quick oats and not rolled oats if they’re ending up with runnier consistency? Just a thought.
Hi Stacey! Soo happy to hear this chocolate baked oatmeal turned out well for you! And, good point about the quick oats vs rolled oats as that would definitely make a difference. I’ll have to check with the other commenters! Lastly, thank you so much for coming back to leave a comment/star rating. I really appreciate it!
Hi Lorin. This recipe isn’t really supposed to make bars. It’s baked oatmeal so it is supposed to be creamy like oatmeal and have less structure. Check out my recipe for baked oatmeal bars if you’re looking for an oatmeal bar recipe.
I just made this today. It is so scrumptious! Mine came out a little wet and I’m not sure if I use too much banana or why, but next time I think I will add an extra quarter cup Of oats.
I did give it extra time in the oven and that helped. But boy, is it good! I used Lillys Stevia sweetened dark chocolate chips. I forgot to add nuts so I sprinkled pecans on after I served it. I’m in love with This!
Woo! So glad you’re loving this recipe, Marry Ellen. The bananas could have been too liquidy or maybe it just needed more time to cook in the oven. But I’m glad it turned out for you!! Thanks for taking the time to leave a comment + star rating. I so appreciate it. <3
Turned out amazing – really healthy dessert without refined sugar, 1/9 of tray makes a decent slice which is less than 160calories. Goes really well with coconut yoghurt. Thanks!
Hey Reece, I typically store baked oatmeal in an airtight container in the fridge. It’ll last about 5 days. Or you could portion it out and freeze the single portions for a later date. It’ll last about 3 months in the freezer.
I’m such a huge fan of oats for breakfast and your baked oatmeals are so delish!! This one is even more fabulous because who doesn’t like chocolate for breakfast?!
…especially when it’s loaded with a whole bunch of nutritious ingredients!
Ahh yay! So glad you’re loving the baked oatmeal recipes, Erica! I’m always for chocolate for breakfast. Thanks for coming back to leave a comment + star rating. I so appreciate it. 🙂
Great way to mix up baked oatmeal! Very indulgent tasting for breakfast! I used oatmilk, an egg instead of flaxseed, added a TB of chia seeds, and agave instead of maple syrup. Ended up baking for around 40 min, and probably could have gone 5 minutes more (didn’t want to overbake, and cocoa powder can make it tricky to judge!). Really delicious! Next time I think I’ll use another half cup of oats since I think the wetness of the recipe can handle it, and add some nuts or frozen cherries 🙂
I’ve been looking for low cholesterol recipes with oatmeal and found this one. I used an egg and opted for sugar free syrup. To be honest, I did not love this the first day. On day two I heated up a piece in the microwave and put a squirt of sugar free syrup on top. That’s the trick! All the breakfast brownie taste with the benefits of oatmeal! This is delicious and I will definitely make it again. It’s an easy quick breakfast and fits nicely into my meal prepping plans.
Ahh yay!! So glad you ended up liking this recipe, Jenifer. 🙂 Thanks for making it and for coming back to leave a comment + star rating. It means the world to me!
This is my life saver in times of desperate chocolate craving 🙈
I made it less sweet by using only half of the maple syrup. Thanks for sharing the recipe☺️🤗

This oatmeal is so tasty! I used coconut milk and substituted a little unsweetened applesauce because I didn’t have any bananas. IMO I didn’t think it needed additional drizzle of PB or syrup. I’m excited to try some of the other options here at EBF.
Ahh yay!! I’m so glad you enjoyed this baked oatmeal recipe, Lauren. Thanks for making it and for coming back to leave a comment + star rating. It means the world to me. 🙂
This was amazing! I made a few tweaks based what I had/wanted. I used applesauce instead of bananas, put all the chocolate chips inside, put chopped walnuts on top, and used 1% milk. All in all it was amazing, thank you for coming up with this recipe! 🙂
So glad you enjoyed this recipe, Kaitlin! Thanks for making it and for sharing the subs you made in your comment. It’s super helpful for other readers 🙂
First time trying this and I love it! I didn’t use egg or flaxseed and used almond butter and honey. It’s really healthy and almost feels like you are eating a dessert for breakfast! What’s not to love?!
Ahh yay!! So glad this recipe turned out without the flax egg or regular egg – thanks for sharing and for coming back to leave a comment + star rating, Kate. I really appreciate it. <3
Wow, this was delicious! I used one of those small cups of applesauce since I didn’t have bananas, and I used espresso chips for the chocolate chips. I also used special dark cocoa powder, so it ended up being a dark chocolate-espresso kind of baked oatmeal. Easy to prepare and incredibly tasty!
Ohh I love the espresso addition!! I might have to try that at some point. 🙂 So glad you enjoyed this recipe, Maddy. Thanks for trying it and for coming back to leave a comment + star rating. I so appreciate it!!
This is so good! I didn’t add the flaxseed and I was afraid of it tasting egg-y so I didn’t add that either and it was just fine. It tastes like dessert I’ve had it cold as a snack too! Cant believe it’s not higher in calories because it really is so good! Thank you for the recipe!
Ahh yay so glad you enjoyed this recipe, Melissa! And so glad it turned out for you without the egg or flax egg. Thanks for sharing and for coming back to leave a comment and star rating, it’s super helpful for other readers. 🙂

Can I leave the peanut butter out or will it change the consistency? 🙂
It will change the consistency a tiny bit, but you can leave it out!
This was so delicious. I absolutely loved it! Like many others said, it did need some extra time to bake, but turned out well. Totally recommend!
★★★★★
So glad you enjoyed this recipe, Claudia. Thanks for the review, I appreciate it!
Used rasberries instead of bananas and it was soooooo good. Hubby and I devoured it. This will be a regular thing on the breakfast menu now!
★★★★★
Ahh yay! So glad this recipe turned out for you. Love that it worked with raspberries. 🙂
This came out mushy even after I drained almost a cup of liquid out before baking.
★★★
Oh no! You definitely shouldn’t have to drain liquid out before baking. Did you change anything about the recipe? How long did you bake it for?
I followed the instructions however, my bars took over almost an hour in the oven. Which I felt the bars still were pretty liquidy inside. 😕

I have not made this but want to try it. However, can i leave the banana out?
Hey Sarah! I would swap in the banana with applesauce if you have it on hand. 🙂

What can I use in place of maple syrup?
Hey Glory – You could use honey, agave, coconut sugar or really any sugar of choice. 🙂
Could I leave the coconut oil out?
Hey Becky – If you don’t have coconut oil on hand you could swap it with another oil or butter.
I had this for breakfast this morning and it did not disappoint! Soooo yummy. I will absolutely be making this again.
