EASY BAKED PEANUT BUTTER OATMEAL BREAKFAST
There is something about sweet and chewy oatmeal that is guaranteed to get them out of bed, spike it with peanut butter and serve warm with milk or your favorite toppings and it’s hard to resist.
Baked Peanut Butter Oatmeal is delicious warm right out of the oven, heated up in the microwave or even cold. While we love baked oatmeal for breakfast it also makes a wonderful mid-day snack with a glass of milk or cup of coffee.
Once you find out how delicious and easy this baked oatmeal recipe is, you’ll never go for the pre-packaged microwave oatmeal again.
EATING BREAKFAST IS IMPORTANT
Having family dinner time has always been important in our house, and most nights we eat dinner as a family. But breakfast is a meal that we rarely eat together unless we are having breakfast for dinner. 😉
Many people skip the morning meal because they’re rushing to get out the door. But that’s a mistake.
Breakfast is the most important meal of the day, do you know why?
- Energy and Concentration: People who eat a nutritious breakfast with protein do better in school and at work. They won’t get hungry before lunch, and the protein will keep them from getting sleepy, cranky or even headaches.
- Burn Calories: Breakfast kick-starts your metabolism, helping you burn calories throughout the day.
- Good Health: Studies show eating breakfast leads to good health like lower levels of “bad” LDL cholesterol, and lower chances of getting diabetes, heart disease, and being overweight.
Having something quick and delicious around for breakfast, like Baked Peanut Butter Oatmeal is a great way to make sure everyone fuels up for the day. Baked oatmeal is both nutritious and deeply satisfying and a much better alternative to cold sugary cereal.
HOW TO MAKE BAKED PEANUT BUTTER OATMEAL
(full printable recipe at the end of this post)
Making baked oatmeal is as simple as can be, it’s also a great make-ahead meal. Make this simple baked peanut butter oatmeal on the weekend and have a delicious, healthy breakfast to enjoy all week long. You can eat it cold or heat it in the microwave just a bit.
We like to separate the baked oatmeal into single servings and place each cooled serving into its own airtight container in the refrigerator. This way you can have a grab and go breakfast ready every morning for the whole workweek.
Start by preheating the oven to 350°F, and grease a large baking dish. Then, using a large bowl, mix all of the oatmeal ingredients until well combined. Next, transfer the oatmeal to the prepared baking dish and bake in the oven until edges are golden brown. A knife inserted in the center will come out mostly clean with a few wet crumbs.
Serve with warm milk poured over the top and a drizzle of peanut butter if desired.
TIPS FOR MAKING THE BEST BAKED PEANUT BUTTER OATMEAL
- Be sure to use rolled or old-fashioned oats for the best results when making this peanut butter oatmeal. Quick oats will work in a bind, but will not hold the texture and can become mushy, steel-cut oats will come out crunchy.
- DON’T overbake the oatmeal! Even if it doesn’t look quite done at first, it will continue to bake in the pan even after you take it out of the oven.
- Wait to dig in. Allow the baked oatmeal cool for 10 minutes before serving.
- If you like a crunch in your oatmeal try adding some chopped pecans, peanuts or walnuts.
Baked Peanut Butter Variations
While this oatmeal is delicious with just a little milk poured over the top, make it your own with delicious toppings.
- slice bananas on top sprinkle a little cinnamon then pour warm milk
- sprinkle with a few mini chocolate chips and or pecans
- add yogurt and a little maple syrup
HOW TO STORE PEANUT BUTTER BAKED OATMEAL
You can keep leftover baked oatmeal in the refrigerator for up to a week. Just reheat it when you’re ready to enjoy!
To Freeze: Allow the oatmeal to cool completely. Store individual servings of the oatmeal in airtight freezer bags or containers. Reheat in the microwave with a tablespoon of water.

Everyone should have a good set of mixing bowls in their kitchen. This set is my favorite because the variety of sizes means I always have exactly what I need available.
Sometimes I want to switch things up from just a normal square or rectangle casserole dish, and this oblong one does just the trick!
With the prices vanilla skyrocketing, I like to make my own vanilla, because it’s so easy and just as good!

That looks delicious!
This looks soooo yummy! I’m the same way about breakfast. I don’t like to eat as soon as I get up so it messes up my day a bit. But I’m happy to cook on the weekend! I think I’ll add this to my list of things to make!
I bought all of the ingredients to make this oatmeal this week!!!
Okay not many people know this but my surfer is addicted to three things. Two of which are peanut butter and oatmeal. This will be made Sunday for him no matter what. Drool buckets love!!
I didn’t even know you could do this! It looks SOOO good! Now, could I use pumpkin or something in place of the peanut butter? I have a non-peanut kid.
I have done many other types of baked oatmeal, just google it and you’ll fine plenty of peanut free recipes. I typically do an apple/cinammon one, but going to try this one!
I have made this several times and it is so yummy. I cut in to pieces, individually wrap and then freeze what we don’t eat for breakfast. We take out what we need for another breakfast or for a snack (just like eating a peanut butter cookie, not that I would know, he he). Love this recipe.
This looks so yummy! gonna try this out this week! I have to admit: I love peanut butter!
I’m going to have to try this with almond butter. I bet it is a great start to the day!
This sounds delicious, almost like a peanut butter oatmeal cookie.
This sounds fabulous! I’m licking my lips just thinking about it!
I love the idea of pouring milk over this oatmeal! My kids would go crazy for this.
Oh my but this looks so good and interesting with the peanut butter. I love a hot bowl of porridge in the morning throughout the winter months. I just may have to try this out. For a wholesome snack, this recipe is perfect!
I love this recipe! WIll be making it soon!
I was just looking for a baked oatmeal! Thanks!
This looks so YUMMY!
I LOVE oatmeal!
Gotta try this!
And I KNOW it smells so yummy while baking!
I’m going to feature my BUSH Beans soup this week! xo
I need to try this! It sounds so good! How long do the leftovers last?
I hope that made sense…I’m sure it’s gobbled up quickly, but can you keep leftover of this for a few days without it going bad?
Oh, my!! This sounds delicious! I’m going to have to try it soon. Maybe even my pickiest breakfast eater will like this–my fingers are crossed!
What a good idea! My hubby eats oatmeal every morning. We are going to have to try this!
This is definitely going on my “must try” list!! Oatmeal cookies are my FAVORITE!!!
Oh, yum! I am also trying to make more breakfasts for my family. I’ll serve this up tomorrow morning. Thank you.
Making it tomorrow morning! Come link this up for a chance to win my Get Organized Giveaway!
I like the idea of adding peanut butter to the baked oatmeal, I make this frequently.
Oh my! This looks delicious, Cheryl!!!
Oh my, thank you for sharing this recipe! My absolute favorite breakfast is pb & banana oatmeal on the stovetop, but I never thought of making it into a baked oatmeal. I’m going to have to give this a try and maybe try adding some mashed bananas as well!
These look amazing
Not sure if my comment worked before — let me try again..
These look AMAZING!
Thanks for sharing
This is really tasty, and a welcome treat for me as I can’t eat wheat or sugar. I substituted soy nut butter for the peanut butter, stevia powder for the sugar, and added some mashed banana for more moisture and flavor. Great! Thanks!
I’m making this right now as a dessert for after dinner! Thank you! I might put some melted chocolate chips on top to give it the “dessert” feel. 😉
I just made this and it is yummy. I made a few changes.
Instead of the 1/4 cup white sugar and 1/4 cup brown sugar I just used 1/2 cup raw sugar. I also used Adam’s peanut butter and added 1/2 cup raisins.
I thought about adding chocolate chips but then remembered this is supposed to be breakfast not dessert. 🙂
As someone who eats in the car on the way to work early in the morning, this looks like it will be put into my rotation of “something fast and something healthy”.!
That looks delicious! And anything with peanut butter is amazing in my book 🙂 Can’t wait to try this recipe – thanks for sharing!
Oh boy, I’d get out of bed for this giant cookie any day! 🙂
Gonna try this one the weekend I am off. The grandabies are gonna love it!
The Prof LOVES peanut butter oatmeal so this one is a no-brainer!!
Yum! This oatmeal looks amazing… I love baked oatmeal!
Yum! I bet it would be delicious with a little jam or some dried cranberries in it, like a PB&J!
yum yum yum. i already love oatmeal and peanut butter, so i’m SOLD!
Oh my goodness. This sounds so good. If I didn’t just make a HUGE batch of pumpkin oatmeal I might be making this for tomorrow’s breakfast. I love it. I’m bookmarking it *and tweeting!* because I need to have it in my “memory!” SO yum!
I love peanut butter in my oatmeal so I can’t WAIT to make this!!
Looks fun and delicious!!
I will give it a try!
By the way . . .my name is Cheryl, too, and I love how you sign your name. 🙂
Thanks for all the good ideas!
Looks so delicious. I love peanut butter in my oatmeal!
This looks so great! Peanut butter takes up about 98% of my diet, and I’m a huge fan of oatmeal. Cannot wait to try this!
This was the first thing I ever made on Pinterest (about a year and a half ago), and I had no idea there was such thing as baked oatmeal before! I make this all the time…I’m eating some as we speak…and I love that you told your kids it tastes like a big cookie. 🙂 I’m going to tell my kids that as well, one day when I’m a mom. Thank you so much for introducing me to one of my new favorite breakfasts of all time. You’re awesome!
This is my go to oatmeal. You have come up with one of the best! In fact other than cookies this is the only oatmeal I will eat. Thank you so much for such a great recipe!
This tasted FANTASTIC. Great recipe!
I have been making this recipe of yours for years. It is my 14 year year olds favorite breakfast . He wants it all of the time.
What can I substitute for the white and brown sugar?
