If you love a flaky croissant and the sweet bite of a donut, these air fryer croissant donuts (aka cronuts) bring the best of both in a faster, friendlier way. Theyâre light, layered, and golden with a tender centerâno deep frying needed. You only need a few simple ingredients and about 20 minutes of hands-on time.
The air fryer keeps things crisp without the mess, and the results feel bakery-level. Make them plain with sugar, glaze them, or fill themâeither way, theyâre a crowd-pleaser.

What Makes This Special
Classic cronuts are usually deep fried, which can be messy and heavy. This version uses the air fryer for a lighter, cleaner finish that still delivers that flaky crunch.
Using store-bought croissant dough or puff pastry keeps things doable on a weekday without compromising on texture. Youâll get a golden exterior and soft, buttery layers inside. Plus, you can customize the coating, glaze, or filling to match your mood.
Ingredients
- 1 can refrigerated croissant (crescent) dough or 1 sheet puff pastry, thawed but still cold
- 2 tablespoons melted butter (optional, for richer flavor)
- 1/3 cup granulated sugar, for coating
- 1 teaspoon ground cinnamon (optional)
- Nonstick spray or a little neutral oil for the air fryer basket
- Optional glazes and fillings:
- Vanilla glaze: 1 cup powdered sugar, 2â3 tablespoons milk, 1/2 teaspoon vanilla
- Chocolate glaze: 1/2 cup chocolate chips, 1 tablespoon butter, 1â2 tablespoons milk
- Fillings: pastry cream, lemon curd, strawberry jam, or Nutella
How to Make It
- Preheat and prep. Preheat your air fryer to 350°F (175°C) for 3â5 minutes.
Lightly mist the basket with nonstick spray or brush with oil.
- Shape the dough. If using croissant (crescent) dough, unroll it and press seams together to form a flat sheet. If using puff pastry, lightly flour your surface and roll it to about 1/4 inch thick.
- Layer for flakiness. For extra lift, fold the dough in thirds like a letter, then roll it back out to roughly 1/2 inch thick. This creates more layers and a taller donut.
- Cut the donuts. Use a 3-inch round cutter or the rim of a glass to cut circles.
Use a 1-inch cutter (or bottle cap) for the centers. Gently re-roll scraps as needed. You should get 6â8 donuts plus holes.
- Brush with butter. Lightly brush the tops with melted butter for color and flavor.
This is optional but helps them brown beautifully.
- Air fry. Arrange donuts in a single layer with space between them. Air fry at 350°F (175°C) for 5â7 minutes, flip, then cook 3â5 minutes more until puffed and deep golden. Donut holes take less timeâcheck at 4â5 minutes total.
- Coat or glaze. While still warm, toss in a mix of sugar and cinnamon.
Or let cool slightly and dip in vanilla or chocolate glaze. If filling, cool fully, then pipe filling into the sides using a pastry bag and small tip.
- Serve. Enjoy warm for the best texture. The layers are crisp outside and tender insideâexactly what you want.
Keeping It Fresh
These are best the day you make them.
If you have leftovers, store them loosely covered at room temperature for up to 24 hours. To crisp them back up, reheat in the air fryer at 300°F (150°C) for 2â3 minutes. If theyâre glazed or filled, refrigerate in a container and reheat briefly without melting the filling, or enjoy cold.
Health Benefits
- Less oil, less mess: Air frying cuts down on added fats compared to deep frying, while still giving that crispy exterior.
- Portion control: Making them at home lets you keep sizes modest and choose lighter coatings like cinnamon sugar instead of heavy frostings.
- Flexible ingredients: You can opt for reduced-sugar glazes or fruit-based fillings to balance sweetness.
Common Mistakes to Avoid
- Overcrowding the basket: If donuts touch, they steam instead of crisp.
Cook in batches for even browning and rise.
- Warm, sticky dough: Soft dough loses its shape. Keep it chilled until cutting and air frying for clean layers.
- Skipping the flip: Flipping halfway ensures even color and prevents pale bottoms.
- Overcooking: Puff pastry and croissant dough brown quickly. Start checking early to avoid a dry interior.
- Glazing too hot: If you glaze while piping hot, it slides off.
Let them cool a few minutes before dipping.
Recipe Variations
- Maple-Glazed: Mix powdered sugar with maple syrup and a splash of milk. Top with crushed toasted pecans.
- Lemon Sugar: Toss warm donuts in sugar mixed with fine lemon zest and a pinch of salt for brightness.
- Chocolate Hazelnut: Fill with Nutella and drizzle with melted dark chocolate. Sprinkle with chopped hazelnuts.
- Boston Cream Style: Pipe in vanilla pastry cream and top with a shiny chocolate glaze.
- Berry Jam-Filled: Use strawberry or raspberry jam and finish with a light dusting of powdered sugar.
- Cinnamon Roll Twist: Brush raw dough with butter and cinnamon sugar before cutting.
After frying, glaze with vanilla icing.
FAQ
Can I use canned biscuit dough instead of croissant dough?
Yes, but the texture will be more like a fluffy donut than a flaky cronut. Croissant or puff pastry gives the signature layers. Biscuit dough still tastes great and cooks in roughly the same time.
How do I know when theyâre done?
They should be deeply golden with visible puffed layers.
The donuts feel light when lifted with tongs. If the centers look doughy after cutting one open, give them another 1â2 minutes.
Do I need to proof the dough?
No. Store-bought croissant or puff pastry is ready to cook once shaped.
Just keep it cold for best lift.
What air fryer temperature works best?
350°F (175°C) is a sweet spot for browning without burning. If your air fryer runs hot, try 330â340°F and add a minute or two.
Can I make them ahead?
You can cut and shape the donuts, then chill them on a tray for up to 4 hours before cooking. Cook just before serving for the best texture.
How do I fill them without making a mess?
Use a piping bag fitted with a small round tip.
Insert it into the side of the donut and gently squeeze until you feel a little resistance. Rotate and add a second pocket if needed for even filling.
Are they safe to freeze?
Yes. Freeze unglazed, cooked donuts in a single layer, then transfer to a bag.
Reheat in the air fryer at 300°F (150°C) for 4â6 minutes, then glaze or sugar.
Why did mine deflate?
Warm dough, overcrowding, or opening the air fryer too often can cause deflation. Keep the dough cold, give them space, and minimize peeking.
Wrapping Up
Air fryer croissant donuts bring bakery-style layers to your kitchen with less effort and no deep fryer. Theyâre crisp, buttery, and endlessly customizableâperfect for weekend treats or last-minute guests.
Keep the dough cold, donât crowd the basket, and finish with a simple sugar coat or your favorite glaze. Once you try them, youâll have a new go-to for fast, flaky sweetness.
