Bake a simple and easy gluten-free apple crisp with a crispy, cinnamon, brown sugar, oatmeal topping. Best served with a scoop of vanilla ice cream!

Is there really anything better than warm apple crisp filled with hints of cinnamon, nutmeg, and brown sugar? It's fall cooking at its finest.

I've always been a fan of apple crumb pie, but now I do believe this gluten-free apple dessert will become another addition to our fall baking traditions.

But don't let the gluten-free part trip you up. You can make this a gluten-free crisp or a gluten-filled crisp, and it will be delicious either way.

Making apple oatmeal crisp is really as easy as prepping the apples and crumbling on a sweet topping. While it takes a little bit to bake, it's actually really quick and simple to throw together.

Not quite in the mood for apple crisp? Try peach crisp instead.

APPLE CRISP VS APPLE CRUMBLE?

I grew up eating fruit cobblers. Cobbler in my mom's kitchen meant a fruit filling with a bottom crust and crumbled crust on top.

If you're like me and not sure the difference between a crisp and a crumble…

Apple crumble is made with either a biscuit dough or a regular pie dough crumbled on top of the apple filling. And sometimes it'll have a bottom crust too.

The topping for a fruit crisp, however, is made with oats, in this case, gluten-free oats. And I use Cup4Cup Gluten-Free Flour, which replaces regular all-purpose flour.

BEST APPLES FOR APPLE CRISP

While you can make an easy apple crisp with apple pie filling, I really recommend fresh apples.

I also recommend finding apples that are in season because you'll get a lot better flavor. And if you buy seconds at a local orchard, produce stand, or farmer's market, you'll get them cheaper too.

Personally, I love making pies, cobblers, and crisps with Jonathan apples, Jonagold apples, or Granny Smith apples. Jonagolds are a cross between Jonathans and Golden Delicious, and they are so sweet, tart, and crisp.

For this recipe, I used Granny Smith. I use a very handy apple peeler/corer to make the job of prepping the apples quicker and easier.

More of the best apples for apple crisp include:

• Jonathan
• Jonagold
• Granny Smith
• Golden Delicious
• Pink Lady
• Honeycrisp
• Braeburn
• and Northern Spy – According to Bob’s Red Mill, this is a rare apple and hard to find; but if you love your apple pie, it’s definitely one you may want to hunt down.

HOW TO MAKE GLUTEN-FREE APPLE CRISP

Making a fresh apple crisp involves a couple different sets of steps. You have to both prep the apples and the crumble topping.

To prep your apple filling…

1. Wash, core, peel, and slice apples into a large bowl.
2. Add butter, sour cream, and lemon juice to the apples.
3. Then mix in the sugar, brown sugar, and salt.
4. Finally, stir in the corn starch and cinnamon 'til everything is mixed well.

Then you'll just take that apple mixture and pour it into a smaller 8″x8″ pan or 7″ to 9″ baking dish and set it to the side.

To get your apple crisp topping ready…

1. In a separate mixing bowl, mix together the oats, flour, brown sugar, cinnamon, and nutmeg.
2. Cut the butter into the oat mixture using a pastry blender.
3. You can stop mixing when the mixture has turned into quite the crumbly mixture.
4. Crumble the topping over the peaches in the baking dish.

Then just bake according to the instructions in the recipe card below. You'll bake it for about an hour, or until the topping is golden brown.

I love serving apple oatmeal crisp with vanilla ice cream. Oh.my.word. It is so good!

I can't wait for you to try this recipe.

DOES APPLE CRISP NEED TO BE REFRIGERATED?

If I were making this ahead of time, I would likely refrigerate and then possibly reheat before serving. I would refrigerate it, mainly because of the sour cream in the recipe.

Just cover it with a sheet of wax paper and let it rest in the fridge.

CAN APPLE CRISP BE FROZEN?

Yes, it can. Just be sure to store it in an airtight container so it doesn't get freezer burn.

And allow plenty of time to thaw in the fridge before re-heating.

ALTERNATIVE INGREDIENTS AND SUBSTITUTIONS

There are a few things you can do to switch this recipe up.

• Add pecans, walnuts or almonds, adding the chopped nuts into the topping.
• If you'd rather not make it a gluten-free fruit crisp, switch out the gluten-free flour for regular all-purpose flour instead. And use regular rolled oats instead of gluten-free oats.
• When your crisp has somewhat cooled, pipe or zigzag a bit of powdered sugar icing on top.
