A cozy little snack that’s sweet, crispy, and almost too easy to make

Bananas and cinnamon are one of those simple pairings that just work. When the bananas hit the air fryer, their natural sweetness deepens and the edges turn lightly crisp, while the cinnamon adds that cozy, bakery-like aroma that fills the kitchen.

These cinnamon sugar air fryer banana chips are wonderfully easy to make and perfect when you want a quick homemade snack without turning on the oven. Just slice a couple bananas, toss them with a little oil and cinnamon, and let the air fryer do the rest.

After a short cook and a few minutes to cool, you’ll have golden banana chips that are lightly crisp, naturally sweet, and perfect for nibbling straight from the bowl.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 25–28 minutes
• Cooling Time: 5–10 minutes
• Total Time: About 40 minutes
• Yield: About 2 cups banana chips

Ingredients

Simple pantry ingredients—that’s all we need here.

• 2 bananas (green or slightly yellow, not ripe)
• 2 teaspoons avocado oil or olive oil
• ¼ teaspoon ground cinnamon

Optional for extra sweetness (if you like a dessert-style chip):

• 1–2 teaspoons coconut sugar or granulated sugar

Bananas that are still a little firm work best because they hold their shape and crisp nicely in the air fryer. Very ripe bananas tend to get soft and burn more easily.

Kitchen Tools You’ll Need

Nothing fancy here—just a few everyday tools.

• Air fryer
• Sharp knife (or mandoline slicer for perfect slices)
• Cutting board
• Small bowl
• Large mixing bowl
• Spoon or silicone spatula

Uniform slices make a big difference, so if you have a mandoline slicer, it’s a helpful little shortcut.

Step-by-Step Instructions

1. Preheat the Air Fryer

Start by preheating your air fryer to 300°F (150°C) for about 5 minutes. This helps the banana slices begin crisping right away.

2. Slice the Bananas

Peel the bananas and slice them into ¼-inch rounds. Try to keep the slices even so they cook at the same speed.

If some are thinner than others, just keep an eye on them during cooking so they don’t overbrown.

3. Mix the Cinnamon Oil

In a small bowl, stir together:

• 2 teaspoons oil
• ¼ teaspoon cinnamon

This little mixture helps the cinnamon coat every slice evenly.

4. Coat the Banana Slices

Place the banana slices in a large bowl.

Drizzle the cinnamon oil over the slices and gently toss until they’re lightly coated.

Be gentle here—banana slices can be delicate.

5. Arrange in the Air Fryer

Place the slices in the air fryer basket in a single layer.

Try not to overlap them. If needed, cook in batches so the air can circulate properly.

6. Air Fry

Cook at 300°F (150°C) for 25–28 minutes.

Halfway through cooking:

• Flip the slices
• Check for browning

During the last few minutes, keep an eye on them so they don’t burn.

7. Let Them Cool

When they come out of the air fryer, they may still feel slightly soft.

Let them cool 5–10 minutes, and they’ll crisp up beautifully as they rest.

8. Serve and Enjoy

Now comes the fun part—grab a handful and enjoy!

Helpful Kitchen Tips

Choose the Right Bananas

Slightly green or yellow bananas are best. They’re firmer and hold their shape during cooking.

Slice Evenly

Aim for slices about ¼ inch thick. If some are too thin they may burn, while thicker slices stay chewy.

Don’t Crowd the Basket

Air fryers rely on circulating air. If the slices overlap, they won’t crisp evenly.

Cooling Is Important

This is the secret step! The chips firm up as they cool.

Flavor Variations

Once you’ve made these once, it’s fun to experiment.

Coconut Cinnamon Chips
Use coconut oil instead of olive oil.

Spiced Banana Chips
Add a pinch of nutmeg or cardamom.

Sweet Dessert Chips
Sprinkle lightly with coconut sugar after cooking.

Chocolate Banana Chips
Drizzle with melted dark chocolate once cooled.

How to Make Them Vegan

Good news—this recipe is already naturally vegan.

Just be sure to use plant-based ingredients like:

• Olive oil
• Avocado oil
• Coconut oil

If adding sweetness, use maple sugar or coconut sugar instead of honey.

Serving Ideas

These banana chips are surprisingly versatile.

Try them:

• Sprinkled over oatmeal
• Mixed into trail mix
• Crushed over smoothie bowls
• Dipped into nut butter
• Served alongside fruit and yogurt

They’re also a great little lunchbox snack.

Storage Tips

If you manage not to eat them all immediately:

• Store in an airtight container
• Keep at room temperature
• Best enjoyed within about 1 week

Avoid refrigerating—they’ll absorb moisture and lose their crunch.

How to Re-Crisp Them

If they soften after a few days:

1. Place them back in the air fryer
2. Heat at 300°F for 2–3 minutes
3. Let them cool again

They’ll crisp right back up.

Frequently Asked Questions

Can I use ripe bananas?

Not recommended. Ripe bananas contain more sugar and become soft or burn more easily.

Why aren’t my banana chips crispy?

Usually one of these things happened:

• Slices were too thick
• Air fryer basket was overcrowded
• They weren’t cooled long enough

Can I make them without oil?

Yes, but they won’t crisp as nicely. Oil helps with both texture and flavor.

Can I use plantains instead?

Absolutely! Green plantains make wonderfully crispy chips with a slightly different flavor.

Can I double the recipe?

Yes—just cook in separate batches so the slices stay in a single layer.

Can I use other fruits?

You can try:

• Apples
• Pears
• Sweet potatoes

Cooking time may vary.

A Little Final Kitchen Note

This is one of those recipes that proves simple ingredients can still feel special. With just a couple bananas and a sprinkle of cinnamon, you get a snack that’s crispy, naturally sweet, and completely homemade.

And honestly, there’s something extra satisfying about making your own chips instead of opening a bag.
