If you’ve made my viral Air Fryer Apples, you know how good warm, cinnamon-spiced fruit tastes straight from the air fryer. That recipe has been such a hit (it even ranks #1 on Google!), and this crisp is like the cozy upgrade — gooey baked apples with a crunchy oat crumble, just like my Healthy Apple Crisp, but sized down for one.
What I love about this version is that it feels indulgent while being made with everyday, better-for-you ingredients: maple syrup instead of refined sugar, rolled oats and oat flour for a boost of whole grains, and the option to keep it dairy-free or vegan. It’s everything you want in a fall dessert, ready in 20 minutes, without a big pan of leftovers.

Why You'll Love This Recipe
- Single-serve, so no leftovers: Perfectly portioned for one (or two), so you can enjoy a fresh, warm dessert anytime.
- Quick and easy: Ready in just 20 minutes in the air fryer, so no oven or long bake time required.
- Healthier twist: Sweetened naturally with maple syrup and made with oats and oat flour for wholesome, whole-grain goodness.
- Diet-friendly: Naturally gluten-free with simple dairy-free and vegan options that still taste indulgent.
- Cozy and crave-worthy: Gooey baked apples topped with a golden, crunchy oat crumble. The ultimate fall-inspired air fryer dessert!
Ingredients You'll Need
- Apple: You only need one apple for this recipe! I love using half a Honeycrisp for sweetness and Granny Smith for tartness — the same combo I use in my gluten-free apple pie. But you can just use whatever you have on hand!
- Maple syrup: My go-to natural sweetener. It keeps the filling refined-sugar-free while adding a cozy, caramel-like flavor.
- 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 provides 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: Pecans or walnuts add a crunchy, toasty bite to the crumble.
See recipe card for quantities.
Easy Substitutions & Variations
- Cornstarch substitute: Use 1 teaspoon arrowroot starch or 1 teaspoon tapioca flour as an alternative.
- Make it gluten-free: This recipe is naturally gluten-free if you use certified gluten-free oats and oat flour.
- Make it dairy-free & vegan: Swap the butter for coconut oil or vegan butter — both work perfectly.
- Make it grain-free (no oats): Replace 2 tablespoon rolled oats + 1 ½ tablespoon oat flour with 3 ½ tablespoon fine almond flour. Keep the 1 tablespoon chopped nuts (add an extra 1 tablespoon for extra crunch if you prefer). If the topping looks dry, mix in an extra ½ teaspoon melted coconut oil.
- Make it nut-free: Leave out the nuts and add sunflower seeds or pumpkin seeds for a crunchy alternative.
- Switch up the apples: Honeycrisp and Granny Smith are my favorites, but Pink Lady or Fuji also work.
- Double the recipe: Double all ingredients and bake in two 8–10 oz ramekins side by side — cook time stays the same.

How to Make a Healthy Air Fryer Apple Crisp
- Step 1: In a small bowl, mix the chopped apple with maple syrup, cinnamon, ginger, cornstarch, and vanilla until evenly coated.
- Step 2: Spoon the apples into a greased 8–10 oz ramekin. It’s okay if it’s filled to the top — the apples shrink as they cook.
- Step 3: Place the ramekin in the air fryer and cook at 360°F for 10–12 minutes, until the apples start to soften and release juices.
- Step 4: While the apples cook, stir together the melted butter, coconut sugar, oats, oat flour, cinnamon, and nuts in the same bowl.
- Step 5: Carefully remove the ramekin and sprinkle the crisp topping over the apples.
- Step 6: Return to the air fryer and cook for another 8–10 minutes, until the topping is golden brown and crisp, and the apples are bubbling at the edges.
Cool slightly, then enjoy warm — straight from the ramekin — with a scoop of vanilla ice cream or Greek yogurt!

My Top Recipe Tips
- Air fry in two steps: Cooking the apples first, then adding the topping, makes all the difference! This way, the apples turn soft and gooey while the crumble gets perfectly golden without burning.
- Cut the apples into the same size: about ½-inch pieces work best. Smaller cubes cook faster, bigger chunks need a little extra time.
- Watch, don’t just time: Every air fryer is a little different. I’ve tested this in three different air fryers, and they all heat a little differently.
- Fill the ramekin to the top: The apples shrink as they cook, so don’t be afraid to overfill the ramekin slightly — it ensures a full, cozy crisp.
What to Serve with Air Fryer Apple Crisp
This single-serve apple crisp is delicious on its own, but here are my favorite ways to serve it:
- With vanilla ice cream: The classic warm-and-cold pairing that makes every bite extra cozy. I'm obsessed with this healthier, high-protein cottage cheese ice cream.
- With Greek yogurt: A healthier twist — add a dollop of vanilla Greek yogurt or coconut yogurt for creaminess and protein.
- With whipped cream: A spoonful of whipped cream (or coconut whipped cream) keeps it light but indulgent.
- As breakfast: It’s wholesome enough for the morning! Pair with Greek yogurt or a drizzle of nut butter for a cozy fall breakfast.
- With nut butter drizzle: Warm almond butter or peanut butter on top is amazing — try it with my peanut butter baked oatmeal bars.
- With a fall drink: Pair it with tea, chai latte, oat milk hot chocolate, or hot apple cider for the ultimate fall dessert moment.
Frequently Asked Questions
Yes! For a grain-free version, replace the 2 tablespoons rolled oats and 1 ½ tablespoons oat flour with 3 ½ tablespoons fine almond flour. Keep the nuts for crunch, or add an extra tablespoon of chopped nuts if you like. If the topping seems dry, mix in an extra ½ teaspoon of melted coconut oil.
Yes! Place the ramekin in a preheated oven at 350°F and bake for about 25–30 minutes. Bake the apple filling for 15 minutes, then add the topping and continue baking until golden brown and bubbling.
Honeycrisp and Granny Smith are my go-to apples, the same ones I use in my Apple Pie Oatmeal Cookies. Honeycrisp adds natural sweetness while Granny Smith brings a tart bite. Fuji and Pink Lady also work well if you like a softer, sweeter filling.
Cooking the apples on their own for 10–12 minutes softens them and makes them gooey (just like an apple pie filling). Then, adding the topping lets it crisp up without burning.
Definitely, just divide the ingredients between two 8 - 10-oz ramekins and cook them side by side. The cook time stays the same.
It’s naturally gluten-free if you use certified gluten-free oats and oat flour. For a vegan version, just swap the butter with coconut oil or vegan butter.
Storage, Freezing & Reheating
This crisp is best enjoyed fresh, straight from the air fryer, while the topping is golden and crunchy. Since it’s a single-serve recipe, you probably won’t 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.
- Microwave: Heat for 30 seconds if you’re short on time (the topping will be softer); I personally use the air fryer method.
I do not recommend freezing; the texture of the apples and crumble will change.

📖 Recipe
Air Fryer Apple Crisp (Single-Serve)
Ingredients
Apple Pie Filling:
- 1 medium apple, Honeycrisp, Granny Smith, or a mix, peeled & chopped
- ½ tablespoon maple syrup
- ½ teaspoon ground cinnamon
- ⅛ teaspoon ground ginger, optional but adds warmth
- 1 teaspoon cornstarch
- ¼ teaspoon vanilla extract
Oat Crumble Topping
- 1 tablespoon butter or coconut oil, melted
- 2 tablespoon coconut sugar, or brown sugar
- 2 tablespoon rolled oats
- 1 ½ tablespoon oat flour
- ¼ - ½ teaspoon ground cinnamon
- 1 tablespoon chopped nuts, pecans or walnuts work great
Instructions
- Preheat: Heat your air fryer to 360°F (182°C).
- Mix the filling: In a small bowl, toss the chopped apple with maple syrup, cinnamon, ginger, cornstarch, and vanilla until well coated.
- Cook apples: Spoon the apples into a single-serve ramekin (8–10 oz). It’s fine if it’s slightly overfilled—the apples will shrink as they cook. Place ramekin in the air fryer and cook for 10–12 minutes, until the apples start to soften.
- Make the topping: While the apples cook, combine the melted butter, coconut sugar, oats, oat flour, cinnamon, and nuts in the same bowl. Mix until it resembles wet sand.
- Add topping: Carefully remove the ramekin from the air fryer and sprinkle the crisp topping evenly over the apples.
- Finish baking: Return to the air fryer and cook for another 8–10 minutes, until the topping is golden brown and crisp.
- Cool & serve: Let cool for 5–10 minutes (it will be very hot). Enjoy warm, straight from the ramekin, with a scoop of vanilla ice cream or Greek yogurt if you’d like.

Notes
- Ramekin size: Use an 8–10 oz ramekin (1 to 1 ¼ cups capacity) for the perfect single serve.
- Best served fresh: The topping is crispiest right after cooking.
- Nutrition info: Calculated for the entire recipe without nuts.
- With walnuts: Adding 1 tablespoon chopped walnuts brings the total calories to ~470.

Tati Chermayeff says
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 🙂
