I feel like this is a breakfast that doesn’t really need much of an intro… Chocolate Peanut Butter Baked Oatmeal basically speaks for itself in the fact that it contains quite possibly the most epic food combo of all time: chocolate and peanut butter.
Chocolate and peanut butter are obviously an epic combo by themselves, but when you bake them in with warm cozy oatmeal… let’s just say they get even better!
Multiply that by the fact that this recipe only has 8 ingredients and takes 35 minutes to make and you’ve got an epic breakfast!

Baked oatmeal has been one of my favorite breakfasts for a while now.
When I was in college I would meal prep things like Blueberry Baked Oatmeal, or Healthy Tropical Baked Oatmeal to eat in the mornings.
I could bake the oatmeal on Sunday, and portion it out so I just had to pop it into the microwave and head out the door on busy mornings – it was awesome!
Let’s get into how to make baked oatmeal.
Ingredients for Chocolate Peanut Butter Oatmeal:
To make Chocolate Peanut Butter Baked Oatmeal you’ll need:

How to make Chocolate Peanut Butter Baked Oatmeal
Making this chocolate peanut butter baked oatmeal is so simple.
- Mix all your ingredients together in a big bowl
- Stir to combine
- Place in a glass 8×8 baking dish.




Bake at 350 for 30-35 minutes until it sets and is golden brown on top. Allow it to cool and slice!
Melty peanut butter, sweet chocolate, warm oatmeal… it’s basically the breakfast combo of the century, and you totally have to try it!

Peanut Butter Baked Oatmeal Substitutions:
This baked oatmeal is super versatile. Sub in whatever ingredients you have on hand to make it, or get creative!
Nut Butter: You can use cashew butter or almond butter instead of peanut butter if you prefer
Skip the chocolate: Baked oatmeal is pretty flexible and you can make a lot of substitutions to it. If you want to skip the chocolate you can sub in fruit. I’d check out this Healthy Blueberry Baked Oatmeal if you’re looking for a fruit oatmeal recipe!
Honey: You can sub maple syrup for honey
Make it vegan : sub egg for one flax egg, sub honey for maple syrup, make sure to use a dairy free chocolate chip
Make it gluten free: make sure you’re using gluten free certified rolled oats.
Optional add ins: chopped nuts, more chocolate, shredded coconut, fresh fruit
Milk: You can use dairy or non dairy milk in this recipe. Try our homemade Walnut Milk or Almond Milk.
Muffins: I haven’t tried making this in small muffin tins but I think it would work! You can probably decrease the cooking time by 5-10 minutes
How long can you keep baked oatmeal for?
Refrigerator: You can keep baked oatmeal stored in the refrigerator for up to a week.
Freezing: If you don’t plan to eat it before then, I would slice it, wrap into individual pieces and place them in the freezer. Then you can just quickly defrost when needed!

Storing/Serving Baked Oatmeal
Serving: This baked oatmeal is great to eat on its own, but you could also serve it with maple syrup/greek yogurt on top! I like to pair it with a slice of Sausage Egg Bake for a balanced breakfast or protein, carbs, and fat.
Storing: I would not store this baked oatmeal at room temp. It likely will get moldy or stale if you don’t refrigerate it.
This baked oatmeal will last in the refrigerator for up to a week.
Freezing: Bake, slice and freeze your oatmeal. You can individually wrap it to make it easier, or allow slices to freeze and then put them in a ziploc bag or container so they don’t stick together. Baked oatmeal will last about 3 months in the freezer.
Reheating baked oatmeal: You can reheat your baked oatmeal in the microwave for about a minute. It might get a little soggy in the microwave but it will still be delicious. You can also pop it in the toaster oven to help it get crispy!
Baked Oatmeal FAQ
Yes, you should refrigerate baked oatmeal. Because it has eggs and milk in it, it needs to be refrigerated to maintain its freshness.
Yes, it’s great to put peanut butter in oatmeal. It melts into the oats, adding lots of flavor and healthy fats!

Brian DePersis says
Looks great, plus it’s easy. Thanks and I can’t wait to try it out.
The Clean Eating Couple says
Thanks, Brian! I hope you love it!
Kimberly says
Looks yummy! Wish I could eat peanut butter!
The Clean Eating Couple says
Thanks, Kimberly! If you can’t eat peanut butter you can definitely swap with almond butter, or a nut free alternative like sunflower butter 🙂
Kimberly says
Yes, I have taken LOTS of probiotics. Would love to give these kind a try. Thanks for doing the giveaway!
cguard says
i like plain oatmeal with dried fruit nuts and yogurt for my morning routine. Your baked oatmeal looks too much on the dessert side of the menu for first thing in the morning but might make a great midmorning snack. My yoga instructor was recommending probiotics would help us stave off some of the nasty winter bugs flying around.
The Clean Eating Couple says
You could eat this as a snack if you don’t want it for breakfast. There’s probably the same amount of sugar in this as there would be in an oatmeal with dried fruit, it’s not as sweet as you would think. I’m not sure if the probiotics will help with all the germs, but it’s definitely worth a shot!
Michelle says
Could you use chocolate protein powder instead of baking cocoa?
The Clean Eating Couple says
Hi Michelle,
You could try this but I’m not sure how it would turn out. It might make the oatmeal a little dry. If you try it let me know!
Heidi says
Yum! Def going to try this! Is this two servings? I just recently started taking a probiotic as well and am about to run out…this would be convenient.
The Clean Eating Couple says
Hi Heidi- This recipe is for 4 servings. I have it photographed in two little ramekins, but if you bake it in an 8×8 pan you can cut it into 4 good size squares 🙂 Enjoy!
Heidi says
Made this last night and cut it into 36 squares like bites and they are heavenly!!! Thanks!
The Clean Eating Couple says
Yay! That made my day! If you share a picture of it make sure to tag us on Instagram, I’d love to see your creation 🙂
betty says
I made this recipe last night but didn’t have an 8 inch cake pan so made them in a muffin tin with cupcake liners but forgot the egg but luckily my husband loved them 🙂
The Clean Eating Couple says
Yay!! Love the idea of baking them in muffin tins – perfect for grabbing on the go!
Dawn says
I have always had problems with bloating. My digestive system does not always like to work with me. I’m really pumped to try these vitamins out! And by the way, the oatmeal recipe looks scrumptious 🙂
The Clean Eating Couple says
Thank you so much! I think that probiotics really have helped my digestion, but every body is different so it might take some time to find what works for you!
Christina Mason says
Made this last night and it was AMAZING this morning. Like, so amazing that I had it for lunch too! Thanks again for another wonderful recipe!
The Clean Eating Couple says
Yay!! I’m so glad you liked it! That makes me so happy 🙂 You should try this Blueberry Baked Oatmeal next!
Suzanne Holt says
Absolutely delicious! The kids love it, and it is healthy too!
The Clean Eating Couple says
So glad you + your kids like it, Suzanne!
Ashley Orfitelli says
Easy & tasty recipe! I baked it over a weekend and brought it for breakfast during the week! I would definitely make it again!
The Clean Eating Couple says
So glad you liked it, Ashley! This makes me so happy to hear!
Mary says
Can you use pb2 instead of peanut butter?
The Clean Eating Couple says
I haven’t tried that Mary. I’m not sure if it would work but I think it would be fine if you mixed it with water per the directions on the pb2 package. It might come out a little dry due to the lack of oil, but if you try it – let me know!
Michelle says
This is a great recipe and super easy. This is my second time making this week lol. It’s definitely a good breakfast option.
The Clean Eating Couple says
Thank you so much, Michelle! I’m so glad you like it!
Hayley says
Super yummy and easy breakfast! We make the blueberry version of this often, but went with the chocolate and peanut butter as a special Saturday morning breakfast with the kids!! It was perfect for a rainy morning at home!
The Clean Eating Couple says
So glad you + your family enjoyed it, Hayley 🙂
Fiorella says
I was looking for the best way to incorporate fiber and protein in one dish and this was the best!!! Thank you
The Clean Eating Couple says
So glad you like it, Fiorella!
Lisa says
Would this be possible to make with veg oil instead of coconut oil? I would love to try these but staying away from stores right now! Thanks! Stay safe!
The Clean Eating Couple says
Hi Lisa- You can use any oil in this: olive, avocado, vegetable.. even melted butter! They’re all listed under the substitutions section 🙂
Christina Mason says
By far one of the easiest healthy breakfast recipes out there. So easy to make with staples you already have on hand and so DELICIOUS!
The Clean Eating Couple says
Thank you so much, Christina! It’s one of our fav breakfasts too!
Vanessa says
Thanks for sharing! Does it keep long?

Storing: I would not store this baked oatmeal at room temp. It likely will get moldy or stale if you don’t refrigerate it.
This baked oatmeal will last in the refrigerator for up to a week.
Lacey Kearbey says
Made this for the first time this week and it was amazing!! It tastes great warmed up a few days later and it only takes a few minutes to mix together and throw in the oven! I was also really happy to see the ingredients were all items I already had on hand!
The Clean Eating Couple says
So glad you liked it, Lacey! Thank you so much!
Jenna Averitt says
Yummy! I accidently forgot the egg and subbed cocoa nibs for chocolate chips but it turned out so good! First time making baked oatmeal. Can’t wait to try the blueberry one next 😍
The Clean Eating Couple says
Sounds delicious, Jenna! So glad you liked it 🙂
Brynna says
I made this for breakfast this morning and it was so yummy!!! I kept going back for more heaping spoonfuls!
The Clean Eating Couple says
Glad you liked it Brynna! It’s one of our favorites too 🙂
Daryn says
Can’t wait to try this, Does it come out very moist with all the milk that’s in it or will it change the density of it after being left in fridge maybe I should add more milk the morning that I am going to have it?
The Clean Eating Couple says
Hi Daryn – it’s not moist like a bowl of regular oatmeal, it almost has a dense-cake like consistency. I would definitely not recommend adding milk to this when you serve it, I don’t think that will be very appetizing. I would serve it as the pictures show, sliced – warm or cold.
Mallory Landuyt says
I’m not someone who is entirely in love with oatmeal, but I love a fast breakfast! I gave these a try, and I was really happy with the ease of making these. I would definitely make these again as the texture was different than a standard bowl of oatmeal. Plus who doesn’t love peanut butter and chocolate chips! I may have even topped with a bit of syrup!
The Clean Eating Couple says
So glad you like it, Mallory!
Cheryl Ann Lugiano says
Awesome!! This is my breakfast go to! Super easy to meal prep and be ready to go. I warm it up the next day 45 seconds in the microwave. I omitted the chocolate chips and added ascend chocolate peanut butter protein powder and it tasted like a no bake cookie!!!! Sooooooo delish
The Clean Eating Couple says
Thank you so much, Cheryl! So glad you liked it!! Love those substitutions!
Kyle says
So easy to make and delicious!
The Clean Eating Couple says
Thanks, Kyle 🙂 So glad you like it!
Liz kane says
This was delicious! I am a big fan of overnight oats but I wanted to try something different for breakfast. I didn’t have coconut oil so I used Ghee and came out perfect . I love this with my coffee
The Clean Eating Couple says
Thank you so much, Liz! Glad you liked it!
Anne says
Very good and really easy. I love that it’s easy to customize too. I make this one frequently.
The Clean Eating Couple says
Thanks, Anne! So glad you like it!
Mary Lee Farley says
I have now loved oatmeal more because of this recipe. It is super easy to make.
The Clean Eating Couple says
So glad you like it!!
Monica Maxwell says
Yummy yum! Amazing. You had me at chocolate and peanut butter. It’s so tasty.
The Clean Eating Couple says
So glad you liked it!
Carly Duszynski says
I really want to love oatmeal bakes, but I never could find a recipe that had the right consistency for my likings… until this one! This was a quick recipe to put together and one that tasted great, even a few days later. Thanks, Liz!
The Clean Eating Couple says
So glad you liked it, Carly! Thank you so much!! This is also delish if you’re looking for another version to try!
Heather Green says
We are the type of people who eat multiple smaller meals/snacks throughout the day. We made these tonight with the intention of having them as a mid-morning snack throughout the week….they may not last until tomorrow! So good!!
The Clean Eating Couple says
So happy to hear this, Heather! Thanks!
Eudora says
Made this today for breakfast! It was so quick to put together. Leaving it in the oven while I got ready for the day, was the reason I tried it out. They came out amazing!!! I substituted pb with almond butter and lightlu drizzled some Walden Farms syrup for a little sweetness.
Will definitely be baking this again!❤
The Clean Eating Couple says
So happy you liked it!
Darla says
The recipes all seem to be delish and healthy.
Jen says
Has anyone tried mixing the night before and baking it the next morning?
The Clean Eating Couple says
I wouldn’t recommend doing that. The oats will absorb the liquid and you’ll be left with a weird version of overnight oats. Just bake it the night before, let it cool, and reheat in the oven or microwave in the morning!
Brit says
This is so good! And I love how there’s so little sugar- didn’t even miss it! Definitely going to be a regular breakfast in our house.
Do you think this would do okay doubled in a 9×13?
The Clean Eating Couple says
I’m so glad you liked it! I think it would probably work if you did that 🙂
