A crackling crust of cinnamon sugar gives way to a tender, cake-like crumb that stays soft for hours. The trick is a brown sugar paste that locks in moisture without the risk of overmixing. These cinnamon sugar donuts are proof that baked can still satisfy that fairground craving, with a clean bite and no greasy residue.
Brown Sugar-Butter Paste
Most donut recipes cream butter and sugar to trap air, but that method risks overmixing, your batter gets tough, and the donuts turn dense. Here, you mash melted butter into brown sugar until it forms a thick paste. That paste disperses fat and sugar evenly throughout the batter without any extra stirring.
The result: a tender, fluffy crumb every time. You don’t need to worry about creaming times or softened butter; this shortcut delivers a lighter texture with less fuss.
The paste also keeps the batter moist, so the donuts stay soft even after cooling.
Two Leaveners for Lift and Color
Baking soda needs an acid to activate, and plain yogurt provides that hit. The two react instantly, giving the donuts a quick rise and deep browning in the oven. Baking powder works more slowly, releasing gas as the batter heats.
It lifts the donuts during the middle of baking, when the soda’s initial puff has already set. Together, they create a balanced crumb: light but sturdy enough to hold the cinnamon coating.
Skip either one, and you’ll see it in the color and texture, the donuts come out pale and flat, or they dome unevenly.
Baked, Not Fried
Air-frying these donuts instead of deep-frying cuts the oil by a lot. Without submersion in hot fat, the crumb stays tender and cake-like, never greasy.
The circulating heat still browns the outside nicely, giving you that golden crust you’d expect from a donut. It’s a lighter end result, less heavy on the stomach, but still satisfying.
You get a clean bite without oil pooling on your tongue. That’s the payoff for using an air fryer: the texture of baked goods with fried-looking color.
Butter-Glued Coating
The cinnamon sugar needs something to stick to, and water-based washes just dissolve the sugar into a soggy mess. Melted butter does the job better. Brush or dip each warm donut in butter, then roll it in the cinnamon-sugar blend.
The butter sets as it cools, trapping the sugar crystals against the surface. That coating stays crunchy for hours, it doesn’t weep into the donut or turn gummy. You taste the cinnamon immediately, and the sugar layer adds a crisp snap that contrasts with the soft interior.
This is a baked donuts recipe that delivers the same satisfaction as the fried version, but with less mess.

Ingredient Notes
Brown sugar: Use fresh, soft brown sugar; hardened sugar won’t mash into a smooth paste with the butter.
Plain yogurt or sour cream: Full fat works best. Low fat can make the crumb slightly drier and less tender.
Ground nutmeg: Freshly grated nutmeg is more aromatic, but pre ground is fine if it’s not more than a year old.
Butter for coating: Use salted or unsalted butter, whichever you have. The salt in the donut balances the sweet coating.
Granulated sugar for coating: Standard white sugar works well. Superfine sugar can clump in the cinnamon mix.
I tried whisking until smooth versus just until combined, the smooth batch turned out like hockey pucks; the lumpy one was fluffy.
How to Make Cinnamon Sugar Donuts Step by Step
Make the paste
Mash melted butter into brown sugar until it looks like wet sand with no butter streaks. If it’s too runny, you added extra melted butter, it should hold a shape when pressed.
Whisk dry ingredients
Whisk flour, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly colored. Clumps in the nutmeg can spot-burn, break them up with your fingers.
Combine wet and dry
Pour milk, yogurt, vanilla, and the butter-sugar paste into the dry mix. Stir just until no flour streaks remain, lumps are fine. Overstirring makes the donuts tough; you’ll see a tight crumb if you go too far.
Fill the pan
Spoon batter into each cavity about 2/3 full. Underfilled cavities yield flat donuts; overfilled ones bake into domes with tiny holes. You want a smooth, even surface.
Air fry the donuts
Cook at 320°F for 12 to 16 minutes. At 12 minutes, the tops should spring back when pressed. Underdone donuts look pale and feel spongy, give them two more minutes and check again.
Apply the coating
Dip each warm donut in melted butter, then roll in cinnamon sugar. The butter should sizzle slightly on contact, if the donut is too cool, the coating won’t stick. Set on a wire rack; the sugar will harden into a crisp shell.
Cinnamon Sugar Donuts – Soft, Sweet & Baked
Ingredients
Donuts
- 1/3 cup brown sugar 67g
- 2 tablespoons butter, melted 28g
- 1 cup all-purpose flour 125g
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 teaspoon ground nutmeg
- 1 teaspoon ground cinnamon
- 1 cup milk 240ml
- 1/4 cup plain yogurt or sour cream 60g
- 1 teaspoon vanilla extract
Cinnamon Sugar Coating
- 1 cup granulated sugar 200g
- 2 teaspoons ground cinnamon
- 4 tablespoons butter, melted 56g
Instructions
Donuts
Mix butter and sugar:
Combine the melted butter and brown sugar in a small bowl; this step ensures the donuts turn out fluffy.Whisk dry ingredients:
In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.Combine wet and dry:
Pour the milk, yogurt, vanilla extract, and the brown sugar-butter mixture into the dry ingredients. Stir thoroughly, scraping the bowl sides to integrate all dry bits.Grease donut pan:
Lightly coat a donut pan with olive oil spray.Fill pan cavities:
Spoon the batter into each cavity of the donut pan.Air fry donuts:
Put the filled pan into the air fryer. Cook at 320°F (160°C) for 12-16 minutes.Cool donuts slightly:
Allow the donuts to cool a bit before applying the coating.
Cinnamon Sugar Coating
Coat with cinnamon sugar:
In a separate bowl, mix together granulated sugar and 2 teaspoons cinnamon. Dip each donut first into the melted butter, then into the cinnamon-sugar blend. Set on a wire rack to dry.
What to Swap and What to Keep
Yogurt or sour cream: Buttermilk. Use the same volume. Buttermilk provides the same acidity to activate the baking soda.
The donuts will be slightly more tender and a bit tangier, but the texture holds up.
Nutmeg: Allspice. Use the same amount.
Allspice mimics nutmeg’s warmth with a hint of clove. The donuts will taste spiced but noticeably different, nutmeg is more floral, allspice more peppery.
All-purpose flour: Whole wheat flour (substitute half). Replace up to half the all-purpose with whole wheat.
The donuts will be denser and less fluffy, with a nuttier flavor. The crumb tightens because whole wheat absorbs more moisture, don’t add extra liquid or you’ll get a gummy interior.
Butter (in donut batter): Coconut oil (melted). Use the same weight (28g).
The donuts will be slightly less tender and carry a faint coconut flavor. The paste won’t form as smoothly, oil doesn’t clump with sugar like butter does, so the batter may be slightly looser.
The coating butter should stay dairy for best adhesion.
Tips
- If your donut pan has small cavities, reduce the batter to 1 1/2 tablespoons per cavity to prevent overflow and ensure even baking.
Storage and Serving
These donuts are best eaten within a few hours of coating, while the sugar crust stays crisp. If you have leftovers, store them in an airtight container at room temperature for up to 2 days. The coating will soften over time, but you can restore some crunch by reheating in the air fryer at 300°F for 2 minutes.
Don’t refrigerate them: the fridge draws moisture, making the coating sticky and the crumb dry. For longer storage, freeze the uncoated donuts in a zip-top bag for up to a month. Thaw at room temperature, then dip in fresh melted butter and cinnamon sugar just before serving.
The coating doesn’t survive freezing well, so always apply it after thawing. If you coat the donuts first and freeze, the sugar will weep and turn gummy.
Serve within an hour of coating for the best texture.
Frequently Asked Questions
Can I make these donuts ahead of time?
Yes, but freeze the uncoated donuts for up to a month. Thaw at room temperature, then dip in fresh melted butter and cinnamon sugar just before serving. The coating doesn’t survive freezing well, apply it after thawing for the best texture.
Don’t refrigerate: it makes the coating sticky and the crumb dry.
Why did my donuts turn out dense instead of fluffy?
Most likely you overstirred the batter after adding the wet ingredients. Stir just until no flour streaks remain, lumps are fine, overmixing develops gluten and tightens the crumb. Another possibility: your baking soda or powder is old.
Check they’re within date, the combo of two leaveners is key for lift.
How do these baked donuts compare to traditional fried ones?
They’re tender and cake-like, never greasy, with a clean bite. The air fryer still gives a golden, browned crust from circulating heat, but the interior stays lighter than fried donuts. You get the same cinnamon sugar crunch without oil pooling on your tongue.
Can I use a regular oven instead of an air fryer?
Yes, but the texture and browning will differ. Bake at 350°F for 10 to 12 minutes in a donut pan; the donuts will be slightly less crisp on the outside because oven air doesn’t circulate as forcefully. Check doneness the same way: tops spring back when pressed.
