I made these crunchy cinnamon-sugar banana chips in my air fryer for a healthy, sweet snack that’s ready in just minutes. Cinnamon-Sugar Air Fryer Banana Chips

Why You’ll Love This Recipe

I love how simple these are—just bananas, a touch of oil or butter, sugar, and cinnamon. They satisfy my sweet cravings without guilt, and the air fryer makes them crispier than oven-baked versions. Plus, it’s a fun way to use slightly ripe bananas before they go bad.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2–3 ripe but firm bananas
1 tablespoon coconut oil or melted butter (or olive oil)
1 tablespoon granulated sugar (white or brown)
½–1 teaspoon ground cinnamon
Optional: a pinch of salt or a spray of lemon juice for brightness

Directions

I preheat my air fryer to 350 °F (175 °C).
I slice bananas thinly (about 1/8 inch) for extra crispiness.
In a bowl, I toss slices with oil (or butter), sugar, and cinnamon until every chip is lightly coated.
I arrange slices in a single layer in the air fryer basket—no overlap.
I air fry for 10–15 minutes, shaking or flipping halfway through to ensure even crisping.
Once golden and crisp, I let them cool—they’ll firm up more as they cool.

Servings and timing

Servings: Makes about 4 servings as a snack
Prep time: ~5 minutes
Cook time: 10–15 minutes
Total time: 15–20 minutes

Variations

I sometimes swap coconut oil for olive oil and add a spritz of lemon juice.
A pinch of salt or nutmeg adds warmth and depth.
For a spicy-citrus twist, I’ve sprinkled a bit of cayenne or zest on top.

storage/reheating

I store cooled chips in an airtight container at room temperature—they stay crispy for about 2–3 days. If they lose crunch, I’ll re-crisp them for 2–3 minutes in the air fryer at 300 °F.

FAQs

1. Can I use frozen bananas?

I don’t recommend frozen—once thawed, they get soggy, not crisp.

2. Can I bake these in the oven instead?

Absolutely. I bake them at 350 °F for 20 minutes, flipping halfway. They take longer but still turn out delicious.

3. How thin should I slice the bananas?

About 1/8 inch. Too thick and they won’t get crispy; too thin and they burn.

4. Can I skip the sugar?

Yes! I can make them with just cinnamon or add a drizzle of honey after baking for natural sweetness.

5. How do I prevent them from sticking?

I lightly mist the basket with cooking spray or brush with a thin coat of oil before adding the chips.

Conclusion

These cinnamon-sugar air fryer banana chips are one of my favorite go-to snacks—crunchy, sweet, easy, and healthier than store-bought. Plus, I get a warm, fragrant kitchen while they cook. If I’ve got ripe bananas, an air fryer, and a bit of patience, I love making a batch.
