Ingredients You’ll Need

For the Donuts

2 ½ cups all-purpose flour (plus more for dusting)
2 tsp baking powder
½ tsp baking soda
½ tsp salt
1 tsp cinnamon
¼ tsp nutmeg
½ cup granulated sugar
2 large eggs
½ cup sour cream
½ cup buttermilk
¼ cup unsalted butter, melted
2 tsp vanilla extract
Neutral oil for frying (vegetable or canola)

Crumble Topping

⅓ cup all-purpose flour
⅓ cup light brown sugar
½ tsp cinnamon
3 tbsp cold unsalted butter, cubed

Cinnamon Sugar Coating

½ cup granulated sugar
1 ½ tsp cinnamon
4 tbsp melted butter (for brushing)

Vanilla Glaze

1 cup powdered sugar
2–3 tbsp milk or cream
1 tsp vanilla extract
Pinch of salt

Step-by-Step Instructions

1. Make the Crumble Topping

Start by mixing the crumble so it’s ready to go when your donuts are done. In a small bowl, stir together the flour, brown sugar, and cinnamon. Cut in the cold butter using your fingers or a fork until the mixture looks crumbly, like wet sand with a few small clumps of butter.

Spread the crumble on a parchment-lined baking sheet and bake at 350°F (177°C) for about 8–10 minutes, or until lightly golden and crisp. Let it cool completely; it will firm up as it cools.

Tip: Make extra crumble and store it in a jar, it’s delicious sprinkled over ice cream, yogurt, or muffins.

2. Make the Donut Dough

In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.

In another bowl, whisk the eggs, sugar, sour cream, buttermilk, melted butter, and vanilla until smooth.

Pour the wet ingredients into the dry mixture and stir until just combined. The dough will be soft and slightly sticky, but it should hold its shape.

If it feels too sticky, add a tablespoon of flour at a time until it’s easy to handle, just don’t overmix or your donuts can turn dense.

3. Roll and Cut the Dough

Lightly flour your surface and rolling pin. Roll the dough out to about ½-inch thickness.

Use a donut cutter (or two round cutters) to cut out your donuts, gathering and re-rolling the scraps as needed.

Tip: If you don’t have a donut cutter, use a wide-mouth glass for the donut and a small bottle cap for the hole.

4. Heat the Oil

Fill a heavy-bottomed pot or Dutch oven with about 2 inches of oil and heat it to 350°F (177°C). Use a kitchen thermometer to keep the temperature steady, this ensures the donuts cook evenly and don’t absorb too much oil.

5. Fry the Donuts

Working in batches of 2–3 donuts at a time, carefully lower them into the hot oil using a slotted spoon or spider. Fry for 1–2 minutes per side, until they’re golden brown and puffed.

Transfer to a paper towel–lined tray to drain and cool slightly.

Don’t forget the donut holes, they take just 30–45 seconds per side and are perfect for snacking while you finish the batch.

6. Coat in Cinnamon Sugar

While the donuts are still warm, brush them with melted butter, then dip each side in the cinnamon sugar mixture.

This step adds that iconic sparkle and crunch while also helping the glaze stick later.

The smell at this point is amazing, buttery, cinnamon-sweet, and cozy enough to make the whole kitchen feel like fall.

7. Make the Vanilla Glaze

In a small bowl, whisk together powdered sugar, milk, vanilla, and a pinch of salt until smooth and pourable.

If the glaze is too thick, add a few drops of milk. Too thin? Add a spoonful of powdered sugar. You want it to slowly drizzle off a spoon, not runny but not stiff.

8. Glaze and Add the Crumble

Once the donuts are coated in cinnamon sugar, dip or drizzle the tops with the vanilla glaze.While the glaze is still wet, sprinkle on the crumble topping so it sticks perfectly. Let the donuts sit for 5–10 minutes so the glaze can set slightly before serving.

Tips for Perfect Homemade Donuts

Keep the dough soft: A slightly sticky dough makes fluffier donuts.
Use a thermometer: Oil that’s too hot or cold can ruin texture, 350°F is the sweet spot.
Fry in batches: It helps the oil stay at the right temperature and prevents overcrowding.
Don’t skip the butter brush: It’s what makes the cinnamon sugar stick beautifully.
Serve fresh: These are at their best the same day, especially within a few hours of frying.

How to Serve Them

These donuts are at their absolute best when served warm, while the glaze is still a little soft and the crumble has that irresistible crunch.

Set them on a cake stand lined with parchment or a linen napkin for a simple but beautiful presentation. Pair them with apple cider, chai lattes, or spiced coffee for the ultimate fall morning moment.

If you’re hosting brunch or a weekend breakfast, they make the sweetest centerpiece, a little messy, a lot delicious, and sure to make everyone smile.

Make It Your Own

These Cinnamon Sugar Donuts are easy to personalize!

Add a hint of maple extract to the glaze for a maple-cinnamon twist.
Swap the cinnamon sugar coating for pumpkin spice sugar in October.
Mix in crushed pecans or toffee bits with the crumble for added crunch.
Or skip the crumble and drizzle with extra glaze for a simpler version.

You can even make mini versions for a dessert board or brunch spread, smaller donuts are adorable and bite-sized perfection.

Storing and Reheating

Homemade donuts are best enjoyed fresh, but if you have leftovers:

Store in an airtight container at room temperature for up to 1 day.
Reheat briefly in a warm oven (about 300°F for 5 minutes) to restore that just-fried softness.

Avoid microwaving, it can make the glaze melt and the crumble lose its crunch.
