This baked apple oatmeal is like an apple pie meets cinnamon-y baked oatmeal and then it’s all topped with a generous drizzle of an easy homemade peanut butter caramel sauce. It’s a perfect breakfast for oatmeal lovers alike — myself included!
Fit Foodie Finds literally became famous for oatmeal recipes over a decade ago, and I haven’t stopped since! Now the team and I have created hundreds of overnight oats, oatmeal and baked oatmeal recipes. And this is the newest addition to the collection, and girrrrrl is it a good one. It’s part apple pie part baked oatmeal and 100000% delicious.
what i love about this recipe
You can make it all in one skillet! Sautéing the apples on the stovetop, and then adding the oatmeal topping and finishing in the oven 😋😋😋
The peanut butter caramel drizzle — need I say more?! It’s made with just peanut butter, coconut oil and maple syrup, and oooof it’s just the icing on the cake for this oatmeal bake.
It’s such a stunning dish. 🥰 While this oatmeal bake is relatively easy to make, it’s gorgeous enough to serve at even the fanciest of brunches.
A Few Main Ingredients
- Apples: I love the flavor and texture of Granny Smith apples for baking, but feel free to use your apple of choice. I do recommend peeling the apples as the skin can still be a bit too tough with this shorter bake time.
- Quick-cooking oats and all-purpose flour: These two ingredients together provide the chewy base for this baked oatmeal.
- Eggs: They act as a binder, helping the oatmeal hold its shape and giving it a nice fluffiness once baked.
- Pure maple syrup: This natural sweetener adds a touch of sweetness without being overly processed.
- Unsweetened almond milk: This is the liquid base that helps cook the oats and keeps everything nice and moist. You can use regular milk too if you’re not avoiding dairy.
- Cinnamon: Apples and cinnamon are like peanut butter and jelly; they just work! You’ll find cinnamon in both the apple mixture and the oatmeal 😋.
- Vanilla: A splash of vanilla extract is like a magic touch. It enhances all the other flavors in the recipe.

Our Fav
Deep Skillet
Use this skillet for your favorite one pot meals or other stove top recipes.
here’s a tip!
Be sure to use a large skillet that is deep enough for the apples and the oatmeal topping. A Dutch oven also works well!
Storing Leftovers
Once your baked oatmeal has fully cooled, you can either cover the skillet with foil and store right in that (saves on dishes! 🙌🏻), or transfer into meal prep containers for easy single serve goodness.
Either way, store in the refrigerator for up to 5 days. While you can leave your baked oatmeal out overnight, it will last much longer in the fridge.

Peanut Butter Caramel Ingredients

Instructions
- Preheat the oven to 350ºF.

- Remove the oatmeal bake from the oven and serve with the peanut butter caramel.
Tips & Notes
- What pan is used will determine the bake time. Enamel cast-iron pans run hotter than other pans. Be sure to check for doneness at 15 minutes to see if it is fully baked when using an enamel pan.
