Peanut Butter Baked Oatmeal transforms ordinary oatmeal into something special! I have also heard this called Amish breakfast casserole… which makes me love it more. If you love a good, hearty breakfast, don’t miss my Breakfast Casserole or Homemade Cake Donuts!
Peanut Butter Baked Oatmeal
On top of being fabulous comfort food, this is beyond easy to assemble. This recipe is a kicked up version because I add peanut butter to it. But most variations are the oatmeal, basic spices, and fresh or frozen fruit. We love all versions of baked oatmeal and love how satisfying it is!
How to Make Peanut Butter Baked Oatmeal
The ingredients are simple and this is a one-bowl breakfast, which I couldn’t love more.
Add all the ingredients to a bowl and mix to combine. It should be on the runnier side. Pour into a baking dish (I prefer to use glass for this recipe!) and bake for about 25 minutes, or until the edges turn golden brown. I like to sprinkle a few extra oats on top just for presentation. If you are doing that, be sure they are quick cook oats.
If you want, you can OMIT the peanut butter (no need to substitute it with another ingredient) or substitute it with almond butter if you have an allergy. If you are leaving out the peanut butter, feel free to add some dried cranberries or raisins. This would be more like a traditional Maple Brown Sugar Baked Oatmeal.
How to Perfectly Bake Oatmeal
I vividly remember the first time I made this 8 years ago and how it would crack on top. I freaked out a bit as I was told that cracking means it’s overbaked. While that is true for cakes, it’s not the case for baked oatmeal. You are looking at the edges to make sure they are not burnt. Even with that sweet little crack on top, the interior of this baked oatmeal is so moist, delicate, and sweet. Perfectly done.
How to Serve Baked Oatmeal
As you can see by the first picture in the blog post, we like a little organic maple syrup drizzled on top. Other fun variations are:
- fresh fruit such as banana or strawberry
- adding homemade whipped topping with raisins (my boys favorite)
- fresh vanilla yogurt
And, of course, we love it warm. Quite honestly, this dish has never made it to the “leftover” stage in our house, so I don’t even know if it reheats well! My gut says that yes, it would. Just pop it in the microwave and enjoy. 🙂
Baked Oatmeal
Ingredients
- 1 ½ cups quick cooking oats
- ¼ cup packed brown sugar
- ¼ cup granulated sugar
- ¾ cup milk
- ¼ cup melted butter
- ½ cup peanut butter (creamy or chunky works)
- 1 teaspoon vanilla
- 1 large egg
- 1 teaspoon baking powder
- ¾ teaspoon kosher salt (if using table salt use ½ teaspoon)
Instructions
- Preheat oven to 350°F. Put all the ingredients in a bowl and mix until combined. It will appear very wet.
- Pour mixture into baking dish. I used an 8×8 glass baking dish because I wanted a soft and gooey texture. (If you use a 9×13 pan they will be a little thinner and less gooey, but also more familiar and delicious.)
- Bake for 20-25 minutes or until the edges are golden brown. If it cracks on top don't worry, it's not overdone. An inserted toothpick should be removed with crumbs clinging to it.
- Serve warm.

I will be making this very soon! It looks so yummy! And the possibilities are endless when you start adding different toppings. Thanks for another yummy idea!!
wow – this is a great idea – and I like that it is kid-approved – we are big oatmeal eaters.
We love oatmeal and THAT looks delicious! I have a recipe I’ve been wanting to try for Cherry Almond Baked Oatmeal…now I’m inspired! 🙂
What a great idea! I eat oatmeal every morning and never thought of baking it!
Yum! Is it wrong that I think this would be delicious topped with chocolate ganache?
I just want to crawl up with a bowl of this right now.
I have been keeping an eye on this blog for a little bit even though I am not a mom. I am jealous of the fact that you have people to test all these fun recipes out on. I live with just one other person who doesn’t like sweet breakfasts very much and I have two questions. I really want to try it since I love oatmeal.
1. How sweet did this turn out?
2. Would 5 minute quaker oats work?
Thanks!
I make a baked oatmeal that I love, but I will be needing to try this because I have a family who LOVES peanut butter! And basically, you are eating an oatmeal cookie for dinner or breakfast or whatever! YUM!!!!!
