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.

Hmmm, we love baked oatmeal but have never tried it with peanut butter! (and I like to make it with honey in place of the dry sugars, though in a lesser amount because honey is sweeter)
Also saw this on Tidymom and now I am going to make it for sure! Mmmmm with blueberries!
Beautiful Blog!!!!!! Simply love it….
I have been keeping an eye on this blog from last few days…even though I am not a mom…but am planning to implement this great idea of baking oatmeal with some raisins ..asap for my hubby dear…
WE love baked oatmeal…been making it for a couple of years now…here is the recipe we used with a couple of variations…
THis one involves leaving part of it on the counter overnight…this helps the enzymes to something that helps with better digestion…if that bothers you, just do it all in on step and bake when mixed…
1/2 cup butter, melted
3/4-1 cup sucanat or brown sugar…I have used both with good results, but use just 3/4 cup
3 cups rolled oats
2 cups milk, kefir or buttermilk- I have used both milk and buttermilk with good results…buttermilk has a slight more tang in the finished product.
1 tsp. cinnamon
Let set overnight in a bowl covered with a tea towel
IN THE MORNING ADD:
2 eggs, beaten
2 tsp. baking powder
1 tsp. salt
THEN THE VARIATIONS:
this is what I do…
add a couple of glops of vanilla (I NEVER measure vanilla)
about 1/4 c. chocolate chips-we like milk chocolate
about 1/2 c. coconut
my friend does:
1/2 cup raisins
OR 1 tart apple diced
Bake in a greased 11x 7 pan at 350 for 25-30 minutes.
I DOUBLE THIS RECIPE AND PUT INTO A 9X13 pan…both because I don’t have a smaller pan and I have a larger family….
A Christmas variation is to use eggnog for the milk and add vanilla, 2-1/2 tsp. cinnamon, and 1 tsp. nutmeg…if that is too rich, just add a smaller amount of eggnog…say 1 cup…
Enjoy!
