The trick with these air fryer greek yogurt donuts is knowing when to stop stirring, push the batter a few turns too many and you’ll lose the tender crumb that makes them work. That thick, lumpy batter you’re tempted to smooth out?
It’s exactly what you want. Skip the deep fryer, and you still get a golden crust and a soft middle that feels rich, not lean.
My first batch came out like hockey pucks, dense and rubbery. I had stirred the batter until smooth, not knowing that was the problem.
Yogurt gives cakey crumb without oil
Greek yogurt packs moisture and fat into the batter, which is what normally comes from absorbing frying oil. The acidity in yogurt reacts with baking powder to produce a light, fluffy crumb that mimics a fried donut’s interior.
You end up with a tender, cakey texture but far fewer calories because there’s no deep fryer involved. The donuts feel rich on the tongue, not lean or dry, even though they’re baked in hot air.
Stop stirring once flour disappears
Overmixing develops gluten strands, and those make homemade donuts dense and rubbery instead of tender. Stir the wet into the dry just until the flour is moistened; lumps are fine. Now I stop stirring the moment the flour disappears, even if there are a few lumps, and my donuts come out light and tender.
A thick, lumpy batter is what you want, smooth batter is a sign you’ve gone too far.
Hot air gives golden crust, soft middle
An air fryer circulates hot air evenly around each donut, creating a golden-brown crust without any oil bath. Baking at 320°F lets the center cook through before the outside darkens too much. The donut pan shape leaves room for airflow, so every donut browns consistently.
You get a crisp exterior that gives way to a soft, cakey interior, a result that feels fried but isn’t.

Yogurt is the secret to tender, low-fat donuts
Greek yogurt: Use full fat or 2% plain; nonfat can make the crumb dry and less tender.
All-purpose flour: Standard AP flour works; don’t substitute self rising or whole wheat without adjusting leavening.
Baking powder: Make sure it’s fresh; stale powder won’t give the rise these donuts need.
Granulated sugar: Standard white sugar; superfine or caster works too but don’t use brown or liquid.
Egg: One large egg at room temperature blends more evenly into the thick batter.
Mix the batter until it just comes together
Combine dry ingredients
Whisk flour, baking powder, sugar, and salt in a bowl until evenly distributed. You want a uniform mix to avoid pockets of baking powder that cause bitter spots.
Blend wet ingredients
Stir yogurt, egg, and vanilla until smooth. The yogurt should be thick and not watery; if it’s thin, your donuts will spread and turn dense.
Mix wet into dry
Pour the wet mixture into the dry and fold gently with a spatula. Stop as soon as no dry flour remains, lumps are fine. A smooth batter means overmixing, which makes donuts tough.
Fill the donut pan
Grease the pan well, then spoon batter into each mold, filling about 3/4 full. The batter is thick and sticky; that’s correct. If it runs smooth, you’ve overmixed, next time stop sooner.
Air fry the donuts
Set the pan in the air fryer basket and cook at 320°F for 8 to 10 minutes. Check at 8 minutes: the donuts should be golden and spring back when pressed. If they feel soft and leave a dent, give them another minute.
Cool and finish
Remove the pan from the air fryer and let the donuts cool in the pan for 2 minutes, then transfer to a rack. While still warm, dust with powdered sugar or cinnamon-sugar. The coating sticks best when the surface is slightly tacky.
Air Fryer Greek Yogurt Donuts
Ingredients
- 1 1/2 cups all-purpose flour 188 g
- 2 teaspoons baking powder
- 1/2 cup granulated sugar 100 g
- 1/4 teaspoon salt
- 3/4 cup plain Greek yogurt 170 g
- 1 large egg
- 1 teaspoon vanilla extract
- 2 teaspoons optional toppings (powdered sugar or cinnamon-sugar mix for finishing)
Instructions
Mix dry and wet ingredients:
In a large bowl, combine flour, baking powder, sugar, and salt with a whisk. Separately, blend yogurt, egg, and vanilla. Pour the wet mixture into the dry and stir until barely combined; avoid overworking the batter.Fill donut pan:
Grease a donut pan (silicone or metal) that fits inside your air fryer. Fill each mold about 3/4 full with batter using a spoon.Air fry donuts:
Set the pan in the air fryer basket. Cook at 320°F (160°C) for 8–10 minutes, until the donuts are golden and bounce back when gently pressed.Cool and add toppings:
Take the pan out of the air fryer, allow donuts to cool a bit, then finish with optional toppings like glaze, powdered sugar, or cinnamon-sugar.
Swap the yogurt, but keep the acid
Greek yogurt: Sour cream or buttermilk. Same moisture and acidity, so the crumb stays tender.
Buttermilk is thinner, reduce liquid elsewhere or expect a slightly looser batter. Sour cream gives identical texture, sometimes a tiny tang.
All-purpose flour: Gluten-free 1:1 baking blend. Donuts will be more delicate and less springy. Use a blend with xanthan gum.
Don’t overmix, gluten-free batter thickens faster, and lumps still fine.
Greek yogurt: Nonfat plain Greek yogurt. You get a drier, less tender crumb.
The fat in full-fat or 2% yogurt keeps these donuts moist since there’s no oil in the batter. Nonfat works but the texture suffers noticeably.
Tips
- Fill a piping bag with the thick batter, snip a 1/2-inch opening, and pipe into the greased molds. This avoids drips and gives even portions, so all donuts cook at the same rate.
- If you don’t have a piping bag, use a zip-top bag with a corner snipped off. The thick batter won’t flow easily from a spoon, and the bag lets you control the fill without smearing batter on the pan.
Storage and Serving
These donuts are best within an hour of finishing. The coating (powdered sugar or cinnamon-sugar) goes on while the donuts are still warm, so the surface is slightly tacky and the topping sticks. Once cooled, the exterior softens.
To keep the coating crisp, apply it just before serving, not ahead. Store leftovers in an airtight container at room temperature for up to 2 days. The texture shifts: day one they’re tender, day two they become denser and more cake-like.
They won’t go stale quickly, but the yogurt moisture means they’ll turn gummy if sealed too long. You can gently refresh them in the air fryer at 300°F for 2 minutes, but skip the reheating if they’re glazed; the sugar will burn.
Freezing isn’t recommended. The yogurt batter loses its spring after thawing, and the coating dissolves.
If you must freeze, do it without any topping; thaw at room temperature for 30 minutes, then add fresh coating.
Frequently Asked Questions
Can I make these donuts ahead of time and reheat them?
These donuts are best within an hour of finishing, but you can make them a day ahead. Store leftovers in an airtight container at room temperature for up to 2 days; the texture becomes denser and more cake-like on day two.
To reheat, gently refresh them in the air fryer at 300°F for 2 minutes, but skip this if they’re glazed, the sugar will burn. Freezing isn’t recommended because the yogurt batter loses its spring after thawing.
Why did my donuts turn out dense and not fluffy?
The most likely culprit is overmixing the batter. Stir the wet into the dry just until the flour disappears; a few lumps are fine, and a smooth batter means you’ve gone too far, developing gluten that makes donuts tough. Another cause could be stale baking powder, check that it’s fresh, because it loses power over time.
Finally, if your yogurt was thin or watery, the batter spreads and turns dense; use thick, full-fat or 2% Greek yogurt.
How are these different from traditional fried donuts in taste and texture?
These air-fried donuts have a golden-brown crust and a soft, cakey interior that mimics a fried donut’s crumb, but they’re lighter because there’s no oil absorbed. The exterior is crisp, not greasy, and the yogurt gives a tender richness without the heaviness of deep frying. You miss the distinct fried oil flavor, but the cinnamon-sugar or powdered sugar topping adds sweetness and crunch that feels similar to a classic donut.
