EASY Apple Crisp with Pie Filling and Oats (Just as YUMMY!)

This apple crisp with apple pie filling and oats is probably my favorite fall dessert hack because it’s so easy and delicious. All you need to make this is flour, oats, apple pie filling, brown sugar, margarine, and cinnamon! Get the recipe and see how easy it is!

My kids love all of the fall activities – picking apples with grandma, making fall crafts with apples, and dodging the yearly fall cleanup chores. They also love fall desserts, one of our favorites being apple crisp.

We all love it, but I’m letting the cat out of the bag: I don’t make it with fresh apples. I could, and it’s delicious, but my grandma passed down her favorite apple crisp recipe – the one I grew up on too – and it’s so easy and delish.

Back then it was just called an easy recipe. Nowadays it’s called a recipe hack. Whatever you wanna call it, it’s a delicious apple crisp that whips together in practically no time.

Easy Apple Crisp with Apple Pie Filling and Oats Recipe

Easy apple crisp made with pie filling and oats in a casserole, ready to go in the oven.

First thing, pour your apple pie filling into your 13×9-inch baking dish. We had some amazing homemade kind that we used, but normally we go with the store-bought kind.

You can totally decide how many cans to use. It all depends on your preference for the apples-to-topping ratio. I like a lot of topping so we don’t go crazy with the apple pie filling.

Second, dump in flour, then oats, brown sugar, and cinnamon into a bowl.

Mix it all together.

Margarine cut in pieces, placed on top of apple crisp topping ingredients that will be incorporated with a pastry blender.

Then add in small cubes of cold butter.

Helpful hint: While there are a few different utensils you could use to mix in the butter, try a pastry blender. It’s more comfortable in your hands to work the butter into the dry mixture

Then pop it into the oven. It doesn’t take as long as regular apple crisp because the apples aren’t raw and don’t need to be cooked. It just needs to be in long enough for the crisp to… crisp!

The hardest part is that once it’s done you’ll have to wait at least a few minutes for it to cool off. Try and be patient!

      • This sounds amazing and easy. Easy being the important word. Lol I also think you can make thisto fit any kind of diet yourfollowing. I can’t wait to try it. It’s nice to spend time with your kids in the kitchen. My kids are grown but when it was time for my 29 year old to go to college and the only one she followed was me. She and I spent countless hours in the kitchen while I made dinner or when I baked a dessert to bring to a friends house etc. so she decided Togo toculinary school which made me very proud. Unfortunately she ended up becoming an EMT which I am extremely proud of as well cause my hubby became a CC CARE PARAMEDIC which is where I met him over 33 years ago when we both were volunteers at our local ambulance co. So it runs in the family. She still loves to bake and cook etc. OK I’ll stop ranting. I’ll let you know how mine comes out in a few weeks when I make it.

        • That’s great that you have all those memories of working together in the kitchen with your daughter! It’s one of my favorite things to do with my kids. I can’t wait to hear what you think of the Apple Crisp!
