This cinnamon-sugar air fryer banana chips recipe transforms ordinary bananas into delightfully crispy, sweet snacks with minimal effort. I stumbled upon this technique when looking for healthy alternatives to store-bought chips, and the results were so impressive that it quickly became my go-to solution for using up bananas before they overripen.
I originally created these banana chips when my toddler was going through a picky eating phase. What started as a desperate attempt to incorporate more fruit into her diet has evolved into our favorite weekend snack that the whole family eagerly anticipates.
Ingredients
- Ripe but firm bananas: The perfect balance ensures they slice easily without being too soft
- Coconut oil or melted butter: Creates that essential crispy exterior while adding subtle flavor
- Granulated sugar or coconut sugar: Provides sweetness and helps with caramelization
- Ground cinnamon: Adds warmth and complements the natural sweetness of bananas
Step-by-Step Instructions
- Prepare the Bananas:
- Start with bananas that have just a few brown spots for the ideal balance of sweetness and structure. Slice them into uniform rounds approximately ⅛-inch thick using a sharp knife. Keeping the slices consistent ensures they cook evenly. Too thick and they will remain soft in the center, too thin and they may burn before crisping properly.
- Coat with Cinnamon-Sugar:
- Combine your sugar and cinnamon in a small bowl, stirring until evenly mixed. Gently toss the banana slices in melted coconut oil or butter until each piece is lightly coated. This fat is crucial for achieving crispiness. Sprinkle the cinnamon-sugar mixture over the bananas, turning them to ensure even coverage on both sides. The sugar will caramelize during cooking, creating that wonderful crispy texture.
- Preheat the Air Fryer:
- Always take time to properly preheat your air fryer to 350°F. This usually takes 3 to 5 minutes depending on your model. Preheating ensures the bananas start cooking immediately when placed inside, which helps achieve even crispness rather than steaming the fruit.
- Air Fry the Chips:
- Arrange the banana slices in a single layer in your air fryer basket, being careful not to overlap them. Overcrowding prevents proper air circulation and results in uneven cooking. Cook for 8 to 10 minutes total, but stop halfway through to flip each slice. The edges should turn golden brown and begin to crisp up. Depending on your air fryer model and the thickness of your slices, you might need to adjust cooking time slightly.
- Cool and Serve:
- Transfer the chips to a wire cooling rack immediately after cooking. This crucial step allows air to circulate around the chips as they cool, preventing sogginess from trapped steam. The chips will continue to crisp as they cool, so resist the temptation to eat them immediately. They should snap rather than bend when properly cooled.

My favorite aspect of this recipe is experimenting with different spice combinations. During autumn, I often add a pinch of nutmeg and clove to the cinnamon-sugar mixture, creating a warming fall flavor that pairs beautifully with afternoon tea. The aroma that fills my kitchen takes me back to childhood visits to my grandmother's house, where spiced banana bread was always cooling on the counter.
Storage Tips
These banana chips are best stored in an airtight container with a paper towel to absorb any excess moisture. They will maintain their crispness for about 2 days at room temperature. If they begin to soften, you can refresh them with a quick 1-minute blast in the air fryer at 300°F. I learned through much trial and error that refrigeration is the enemy of crispness with these chips, so always store them at room temperature.
Flavor Variations
While the classic cinnamon-sugar combination is delicious, these banana chips are incredibly versatile. Try sprinkling with cardamom and a touch of vanilla extract for a chai-inspired flavor. For a tropical twist, dust with lime zest and a pinch of chili powder after cooking. My personal favorite variation includes a light dusting of cocoa powder mixed with the cinnamon-sugar for a chocolate-covered banana vibe without all the extra calories.
Kid-Friendly Cooking Project
This recipe makes an excellent cooking activity for children. My six-year-old loves measuring the spices and sugar, while my eight-year-old has mastered the art of evenly slicing bananas with a child-safe knife. The short cooking time means they stay engaged throughout the process, and the reward comes quickly. I find it opens conversations about healthy snacking and how we can transform simple ingredients into something special. Just be prepared for some cinnamon-sugar to end up on countertops and little fingers.

The beauty of these air fryer banana chips lies in their simplicity. What began as a way to prevent food waste in my kitchen has transformed into a beloved family ritual. There's something magical about watching my children's eyes light up as they bite into a chip they helped create, proving once again that the best recipes are often the simplest ones shared around our kitchen table.
Frequently Asked Questions
- → Can I use very ripe bananas?
It’s best to use ripe but firm bananas. Overripe bananas are too soft and will not hold their shape or crisp properly in the air fryer.
- → Can I skip the sugar for a healthier version?
Yes! You can skip the sugar or use a sugar substitute like monk fruit or stevia for a naturally sweet, low-sugar version.
- → How do I make the chips extra crispy?
Slice the bananas very thin and let them cool completely on a wire rack. They continue to crisp as they cool.
- → Can I store these banana chips?
Yes, store completely cooled chips in an airtight container at room temperature for up to 2 days. They’re best enjoyed fresh.
- → Can I use an oven instead of an air fryer?
Yes. Bake at 200°C (400°F) for 12–15 minutes, flipping once. Watch closely as oven temperatures may vary.
