Air Fryer Cinnamon Sugar Donuts
I remember the first time I made these—warm, pillowy rings dusted in cinnamon sugar in under 15 minutes. Air fryer cinnamon sugar donuts are a quick, cozy treat that feels like a bakery pick-me-up without the fuss. They’re perfect for a weekend brunch, an after-school snack kids love, or a last-minute dessert when guests pop by.

Why you’ll love this dish
These donuts hit a sweet spot: minimal hands-on time, no deep frying, and a soft interior with a lightly crisp exterior from the air fryer. They’re budget-friendly (basic pantry ingredients), kid-approved, and elegant enough to serve for a casual brunch. Because they bake rather than fry, they’re less greasy but still indulgent thanks to the butter and cinnamon-sugar coating.
“My family declared these better than the store-bought donuts—fluffy, warm, and gone in minutes.” — a satisfied home baker
Benefits at a glance:

Step-by-step overview
- Whisk dry ingredients (flour, sugar, leaveners, salt, cinnamon).
- Combine wet ingredients (buttermilk, egg, melted butter).
- Fold wet into dry gently to avoid a dense crumb.
- Spoon batter into a greased donut pan and air-fry until golden.
- Toss warm donuts in cinnamon-sugar for that classic finish.
This short roadmap helps you scan the process before you get into the details.
What you’ll need
Key ingredients
- 1 cup all-purpose flour
- 1/2 cup granulated sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 cup buttermilk
- 1 large egg
- 2 tablespoons melted butter
- 1/4 cup granulated sugar (for coating)
- 1 tablespoon ground cinnamon (for coating)
Notes and substitutions:
- Buttermilk: if you don’t have it, stir 1/2 cup milk with 1/2 tablespoon lemon juice or vinegar and let sit 5 minutes.
- Butter: use melted coconut oil for a dairy-free touch (texture will be slightly different).
- Flour: for a denser, nuttier donut try half whole-wheat pastry flour (not a 1:1 swap for all recipes).
Step-by-step instructions
- Preheat the air fryer to 350°F (175°C). Greasing the donut pan prevents sticking.
- In a large bowl, whisk together the flour, 1/2 cup granulated sugar, baking powder, baking soda, salt, and 1 teaspoon cinnamon.
- In a separate bowl, whisk the buttermilk, egg, and melted butter until blended.
- Pour the wet mixture into the dry ingredients. Stir gently until just combined — small lumps are fine; overmixing makes dense donuts.
- Spoon the batter into a greased donut pan, filling each cavity about halfway. This allows room for the donuts to rise without spilling.
- Place the pan in the air fryer basket. Cook at 350°F for 5–7 minutes, or until the donuts are golden brown and a toothpick inserted into the center comes out clean. Check at 5 minutes — air fryer models vary.
- While the donuts cook, mix the coating: combine 1/4 cup granulated sugar and 1 tablespoon cinnamon in a shallow bowl.
- Transfer donuts to a wire rack to cool just until they’re easy to handle (a minute or two). Dip each donut into the cinnamon-sugar and gently shake off excess. For a lighter coating, dust instead of dipping.
- Serve warm. These are best the day they’re made but can be stored for later.
Best ways to enjoy it
Serve these donuts warm with coffee, hot chocolate, or a spiced latte. For a brunch spread, plate them alongside fresh fruit, yogurt, and savory items like scrambled eggs or bacon. For a fun twist, stack a couple on a plate and drizzle a simple glaze (powdered sugar + milk) over the top. If you like a crunchy contrast, pair them with cinnamon-sugar air fryer banana chips for a snack board: https://mixmirth.com/cinnamon-sugar-air-fryer-banana-chips-sweet-snack/
Presentation ideas:
- Dust with extra cinnamon sugar right before serving.
- Offer a small bowl of warmed caramel or chocolate sauce for dipping.
- Serve on a parchment-lined tray for easy sharing at gatherings.
Storage and reheating tips
Short-term storage:
- Room temperature: keep donuts in an airtight container for up to 24 hours to maintain crisp edges and a soft center.
- Refrigerator: if your kitchen is very warm, refrigerate in an airtight container for up to 3 days (texture will firm up).
Freezing:
- Freeze cooled, uncoated donuts in a single layer on a baking sheet. Once firm, transfer to a freezer bag for up to 2 months. Thaw at room temperature.
Reheating:
- Best method: reheat in the air fryer at 300°F for 2–3 minutes to refresh the exterior without drying the inside.
- Oven: 300°F for 5–7 minutes wrapped loosely in foil.
- Microwave (quick): 10–12 seconds, but note the exterior won’t crisp.
Food safety: Donuts with dairy and eggs should not sit at room temperature longer than 2 hours.
Helpful cooking tips
- Don’t overmix: folding until just combined keeps the crumb tender.
- Fill the pan halfway: overfilling leads to misshapen donuts and spillover.
- Check early: air fryer models vary; start checking at 5 minutes.
- Grease well: use nonstick spray or melted butter on the donut cavities, especially if your pan isn’t nonstick.
- Coat while warm: donuts pick up the cinnamon-sugar best when slightly warm; if too hot they can become soggy, if too cool the coating won’t adhere as well.
- Make a test donut: cook one first to confirm timing, then adjust for the rest.
If you’re experimenting with flavors, I used a small twist in the coating once—adding a pinch of nutmeg—and it brightened the flavor beautifully.

Creative twists
- Glazed: swap the cinnamon-sugar for a classic powdered sugar glaze (1 cup powdered sugar + 1–2 tbsp milk).
- Chocolate-dipped: dip half in melted chocolate and chill until set.
- Apple-cinnamon: fold 1/4 cup finely diced apple into the batter and add 1/4 teaspoon nutmeg.
- Vegan version: use a flax “egg” (1 tbsp ground flax + 2.5 tbsp water), dairy-free milk + 1 tsp vinegar for buttermilk, and coconut oil for butter.
- Gluten-free: use a 1:1 gluten-free flour blend formulated for baking; texture may be slightly different.
Your questions answered
Q: How long does it take to make these donuts from start to finish?
A: About 15–20 minutes including heating the air fryer — prep is quick and cook time per batch is 5–7 minutes.
Q: Can I make these without a donut pan?
A: Yes. Pipe or spoon batter into silicone muffin liners and press a small well in the center with the back of a spoon after cooking to mimic a donut hole. Timing may vary slightly.
Q: What’s a good substitute for buttermilk?
A: Stir 1/2 tablespoon lemon juice or white vinegar into 1/2 cup milk. Let sit 3–5 minutes; it will thicken and work as sour buttermilk.
Q: Can I double the recipe?
A: Yes — batter scales easily. Cook in batches; don’t overcrowd the air fryer basket.
Q: Why are my donuts dense?
A: Likely overmixing the batter or using too much flour. Fold gently and measure flour by spooning into the cup and leveling.
