Cinnamon-Sugar Air Fryer Banana Chips

If you’re craving a sweet and crunchy snack but want to keep things on the healthier side, these cinnamon-sugar air fryer banana chips are a must-try.

They’re naturally sweet, lightly spiced, and made with just a handful of simple ingredients. Plus, thanks to the air fryer, you can get them crispy without deep frying or added preservatives.

These banana chips are perfect for snacking, packing in lunchboxes, or topping off a smoothie bowl. Once you try them, you might never go back to store-bought again.

Ingredients

• 2 ripe but firm bananas
  
• 1 tablespoon lemon juice
  
• 1 tablespoon coconut oil or melted butter
  
• 1 tablespoon sugar (white or brown)
  
• ½ teaspoon ground cinnamon
  
• Optional: pinch of salt

Instructions

1. Slice the bananas

Start by peeling your bananas and slicing them into thin, even rounds—about 1/8 inch thick. Try your best to keep the slices the same size. The first time I made these, I sliced some a little too thick thinking they’d be more “chip-like,” but they didn’t crisp up well and ended up more chewy than crunchy. Lesson learned: thinner is better for that perfect crisp.

2. Toss with lemon juice

Once sliced, place the banana rounds into a bowl and gently toss them with lemon juice. This step might seem skippable, but trust me—it helps prevent them from turning brown while cooking. The first time I skipped this part thinking it wouldn’t matter, and my chips came out looking a little sad and dull. A quick lemon rinse keeps them looking fresh and golden.

3. Mix the cinnamon-sugar coating

In a small bowl, stir together the coconut oil (or melted butter), sugar, and cinnamon. Then pour it over the banana slices and toss gently to coat them. The first time I tried this, I dumped the coating in all at once and stirred too hard, which made the banana slices break apart. Go gently here—just enough to coat them without mashing them. If you want to balance the sweetness, you can add a tiny pinch of salt too.

4. Air fry the banana chips

Preheat your air fryer to 350°F. This part’s important—I forgot to preheat the first time and the chips took way longer to cook and didn’t get evenly crispy.

Arrange the banana slices in a single layer in the air fryer basket. Don’t overlap them, or they’ll just steam and stick together instead of crisping up. If you have a smaller air fryer like I do, you’ll probably need to do this in batches.

Air fry for about 10 to 15 minutes, flipping the slices halfway through. Keep a close eye on them during the last few minutes—some thinner pieces can brown really quickly. 

5. Let them cool and crisp

Once they’re done, carefully remove the chips from the basket and transfer them to a wire rack or a plate lined with parchment. They’ll be slightly soft when hot but will crisp up beautifully as they cool. Initially, it would look like  they aren’t done because they weren’t super crunchy right away—but after about 10 minutes, they had the perfect texture.

Tips and Substitutions

• Use firm bananas, not overripe ones, for best results.
  
• You can swap coconut oil for olive oil or melted butter.
  
• If you prefer a sugar-free version, skip the sugar and just use cinnamon.
  
• For extra crispy chips, slice bananas thinner and cook a bit longer at a lower temperature.
  

Frequently Asked Questions

Can I use overripe bananas?

Overripe bananas are too soft and won’t hold up well in the air fryer. They’ll likely become mushy rather than crispy. Stick to firm, yellow bananas with minimal browning.

How do I store banana chips?

Once they’re fully cooled, store them in an airtight container at room temperature. They’ll stay crisp for up to five days. If they start to soften, just pop them back into the air fryer for a few minutes.

Can I make them without oil?

Yes, but the chips might not turn out as crispy. A little oil helps with texture and gives a better finish.

Can I bake them in the oven instead?

Absolutely. Bake at 225 degrees Fahrenheit for 1.5 to 2 hours, flipping halfway through. Watch them closely at the end to avoid overbaking.

Why aren’t my banana chips crispy?

They may be sliced too thick or need more time in the air fryer. Also, remember that banana chips crisp up more as they cool. Be patient before deciding they’re undercooked.

These cinnamon-sugar banana chips are a fun and easy way to satisfy your sweet tooth without going overboard. Once you get the hang of them, you can experiment with different flavors too—think nutmeg, vanilla, or even a little chili powder for a sweet and spicy twist.
