Why This Is My Go-To Single-Serve Dessert
I love a full pan of healthy apple crisp, and my gluten-free apple pie is my favorite thing to make when people are coming over. But when I want something single-serve on a random Tuesday, this is my go-to. It started as a spin on my air fryer apples, which are the same warm cinnamon apples without the crumble on top.
It took me a few tries to get the topping right. Baking everything at once left the crumble soft, and the oats never really crisped. What finally worked was cooking the apples on their own first and adding the crumble about halfway through, so it hits a hot surface instead of sitting in steam.
That second stage is where I used to rush. The topping needs a good 8 to 10 minutes on its own at 360°F. Air fryers vary a lot, so use the range in the recipe card as your guide and pull it when the topping is deep golden.
This has become my favorite weeknight dessert next to my single serve banana bread, and it works with almost any apple you have sitting in the fruit bowl.

Air Fryer Apple Crisp vs Apple Crumble
The difference comes down to the topping A crisp has oats in it, which is what gives you that crunchy, golden texture. A crumble is traditionally just flour, butter, and sugar, so it bakes up softer and more like streusel.
This recipe is a crisp, since the topping is rolled oats, oat flour, and coconut sugar. If you want something closer to an air fryer apple crumble, use the grain-free version above, which swaps the oats for almond flour and gives you a finer, sandier topping.
Ingredients You'll Need
You need one apple and a handful of pantry staples. I use maple syrup and coconut sugar instead of refined sugar, and oat flour instead of white flour, which keeps this gluten-free and gives the crumble more substance than a plain streusel.
- Apple: You only need one. Honeycrisp for sweetness, Granny Smith for tartness, or a mix of both if you have them. It's the same apple I reach for in my apple pie oatmeal cookies, and whatever is in your fruit bowl will work.
- Maple syrup: My go-to natural sweetener. It keeps the filling refined-sugar-free while adding a cozy, caramel-like flavor.
- Coconut sugar: This goes in the crumble, not the filling. It gives the topping that deeper, almost brown-sugar flavor without the refined sugar.
- Cornstarch: Just a teaspoon, but it thickens the apple juices so the filling doesn't run underneath the crumble.
- Rolled oats and oat flour: The combination makes the topping crispy yet tender. It's also naturally gluten-free if you use certified oats.
- Butter or coconut oil: Butter gives the classic rich, crisp flavor, while coconut oil keeps it dairy-free and vegan. Both work beautifully.
- Cinnamon (and a pinch of ginger): Cinnamon is non-negotiable for apple crisp, and ginger adds extra warmth if you have it on hand.
- Chopped nuts (optional): Pecans or walnuts add a crunchy, toasty bite to the crumble. They crisp up in the air fryer in a way they never do in a big oven-baked pan, but the recipe works without them.
See recipe card for quantities.
Best Apples for Air Fryer Apple Crisp
The best apples for air fryer apple crisp are firm varieties like Honeycrisp and Granny Smith, which hold their shape in the air fryer's shorter, more direct heat. Softer apples break down into more of a sauce.
Honeycrisp is my pick for sweetness.
Granny Smith is the firmest and the one to reach for if you want tartness.
You only need one apple, so use whichever you prefer. Pink Lady and Fuji also work if that's what you have on hand.
How to Make Air Fryer Apple Crisp (Step-by-Step)
This cooks in two stages: the apples go in alone first, then the crumble goes on top for the second round. Full quantities are in the recipe card.
- Step 1: Prep the apple filling. In a small bowl, toss the chopped apple with maple syrup, cinnamon, ginger, cornstarch, and vanilla until every piece is coated.
- Step 2: Fill the ramekin. Spoon the apples into a greased 8 to 10 oz ramekin. Fill it right to the top, even if it looks like too much. The apples shrink as they cook.
- Step 3: Cook the apples. Place the ramekin in the air fryer and cook at 360°F for 10 to 12 minutes, until the apples soften and start releasing their juices.
- Step 4: Make the crumble. While the apples cook, stir together the melted butter, coconut sugar, oats, oat flour, cinnamon, and nuts in the same bowl you used for the filling. It should look like wet sand.
- Step 5: Add the topping. Carefully pull out the ramekin and sprinkle the crumble evenly over the apples.
- Step 6: Finish crisping. Return it to the air fryer for another 8 to 10 minutes, until the topping is deep golden and the apples are bubbling at the edges.
What to Serve with Air Fryer Apple Crisp
Let it cool for a few minutes, then eat it warm straight from the ramekin with Greek yogurt or a scoop of my high-protein cottage cheese ice cream. Leftovers are good cold the next morning too, which is how I eat it about half the time.

How Long to Cook Apple Crisp in an Air Fryer
Air fryer apple crisp takes about 20 minutes total at 360°F, split into two stages. The apples cook on their own for 10 to 12 minutes, then the crumble goes on for another 8 to 10 minutes.
- Stage one, apples only: 10 to 12 minutes at 360°F. You want them softened and starting to release their juices, not fully collapsed.
- Stage two, with the crumble: 8 to 10 minutes at 360°F. The topping looks pale for most of this and goes deep golden in the last couple of minutes.
If you're doubling into two ramekins, start checking a few minutes early. Two ramekins in the basket restrict airflow, so the timing shifts.
My Top Recipe Tips
- Don't add the oat crumble during the first cook: When I baked it all at once, the topping just sat there steaming on top of the fruit and the oats never crisped. The apples need those first 10 to 12 minutes on their own.
- Cut the apple into half-inch pieces: Anything bigger and I've found the middles stay firm even when the topping is done. It's the thing that goes wrong most often with this recipe.
- Give the topping the full 8 to 10 minutes: It looks pale and undone for most of that time, which is when I used to pull it. It goes deep golden in the last two minutes, so wait for that.
Substitutions and Variations
- Make it grain-free (no oats): Replace 2 tablespoon rolled oats and 1 ½ tablespoon oat flour with 3 ½ tablespoon fine almond flour. Keep the 1 tablespoon chopped nuts, or add an extra tablespoon for more crunch. If the topping looks dry, mix in an extra ½ teaspoon melted coconut oil.
- Make it dairy-free and vegan: Swap the butter for coconut oil or vegan butter. Both work perfectly.
- Make it gluten-free: This recipe is naturally gluten-free if you use certified gluten-free oats and oat flour.
- Make it nut-free: Leave out the nuts and add sunflower seeds or pumpkin seeds for a crunchy alternative.
- Cornstarch substitute: Use 1 teaspoon arrowroot starch or 1 teaspoon tapioca flour.
- Double the recipe: Double everything and cook in two 8 to 10 oz ramekins side by side. Start checking a few minutes early, since two ramekins in the basket restrict airflow a little.
Storage, Freezing and Reheating
This crisp is best straight from the air fryer, while the topping is still crunchy. It's a single-serve recipe so you may not have leftovers, but if you do:
- Fridge: Cover and refrigerate for up to 2 days.
- Reheat in the air fryer: Warm at 320°F for 3 minutes to crisp the topping again. This is what I do.
- Microwave: 30 seconds if you're short on time, though the topping comes out softer.
- Freezing: I wouldn't. The apples go watery and the crumble loses its texture completely.
Air Fryer Apple Crisp FAQs
Yes. Bake the apple filling in a preheated 350°F oven for about 15 minutes, then add the topping and bake another 10 to 15 minutes, until golden and bubbling.
I peel mine, since the skin can go a little tough and chewy in the air fryer's short, direct heat. If you like the skin or want the extra fiber, leave it on and cut the pieces a bit smaller.
Usually it came out too early. The crumble looks pale and undone for most of the second stage, then turns deep golden in the last couple of minutes. The other cause is adding the topping at the start, which steams it on top of the fruit instead of crisping it.
Yes. Pears work almost identically, and blueberries or a pear and cranberry mix are both good. Softer fruit releases more liquid, so keep the cornstarch in the filling.
Yes. Divide the ingredients between two 8 to 10 oz ramekins and cook them side by side. Start checking a few minutes early, since two ramekins in the basket restrict airflow a little.

Honestly, my new favorite healthy dessert recipe! I love that it is single serve because that means no storing extras or lots of clean up. The oat crumble is super crispy and the apples melt in your mouth 🙂
