This Peach Crisp with Oats features delicious homemade pie filling that bubbles up under a crunchy cake mix topping. It’s a semi-homemade dessert that’s delicious all year long!
One of my favorite desserts growing up was this delicious peach crisp with oats.
My mom would make it with her homemade peach pie filling and serve a big spoonful of it with vanilla ice cream.
This recipe works because it’s:
- Incredibly easy to make. You only need 4 ingredients to make this dessert! And if you don’t have homemade pie filling on hand, you can easily substitute store bought.
- Great any time of year. This peach crisp is great in the fall or winter months, but also for your summer potlucks!
- Absolutely delicious! The juicy spiced peaches and crunchy topping make this dessert a crowd pleaser.
- Easy to customize. Swap the peaches for another favorite pie filling or use a different cake mix. See my suggestions below.
Step-by-Step Instructions
NOTE: The photos for the instructions were taken using only half of the ingredients.
Preheat oven to 375 degrees.
Empty 40 ounces of pie filling (2 – 21 ounce cans of store-bought if you’re not using homemade, or about 4 cups) into a greased 9×13 baking dish.
Mix 15.25 ounces of yellow or spice cake mix with 1 cup of dry oats in a medium mixing bowl.
Add 3/4 cup of melted butter (1½ sticks) to the cake mix and stir until well combined. Add in up to 1/4 cup cold water until the batter is spreadable and not thick.
Carefully dot or spread the cake mixture over the filling in the baking dish.
Bake at 375 degrees for 40 minutes.
Serve warm with whipped cream or ice cream.
Recipe Tips and Substitutions
If you have fresh peaches on hand, you can slice some of those and add them to the pie filling to give this a real homemade taste. Just reduce the amount of pie filling you use to account for the fresh peaches.
If your cake mix is still thick after you’ve added in the melted butter, you can add some of the water in. The cake mix should be sturdy, but still spreadable.
I recently made this recipe and I used an oval 9×13 baking dish and the ingredients filled it almost to the top. If you’re going to use a 9-inch pie plate I would plan on cutting the recipe in half to make sure everything fits. Unless you have a very deep pie plate, then you could make the full recipe.
You can make this crisp with a variety of fillings and mix-ins. Try some of these variations:
- Apple pie filling
- Apple pie filling with fresh cranberries mixed in
- Cherry pie filling
- Peach and apple pie filling
- Peach pie filling with fresh blackberries mixed in
- French vanilla cake mix with coconut flakes mixed in
- Butter pecan cake mix with chopped pecans mixed in
- Chocolate cake mix
- Caramel sauce

FAQs
All three of these are baked desserts with a peach filling, but what differs between them is the topping.
A cobbler is topped with spoonfuls of thick dough, like biscuits.
A crisp is topped with a flour-based mixture with oats, nuts, or coconut to create a crispy texture.
A crumble uses a simple streusel topping made of flour, butter, and sugar and is similar to what you’d find on a coffee cake.
No, you’ll want to remove the skin.
The skin will leave a tough texture on the peaches that won’t be very appetizing while eating. So if you add fresh peaches to this crisp, be sure to peel them first.
If you’re using my recipe for homemade peach pie filling, the skin is already removed!
Yes.
Because of the high sugar content in the pie filling, this crisp is OK to sit at room temperature for up to 2 days. After that, you’ll want to refrigerate it.
Your peach crisp should be eaten within 4 days. So if you put it in the refrigerator right away, it will last for 4 days.
If you leave it out for 2 days and then refrigerate it, it will be good for another 2 days.
Just note that the topping will get soggy the longer it stays uneaten, but it will still taste delicious!
