Full Ingredients

Old-Fashioned Sour-Cream Donut Dough

• 2 2/3 cups (320 g) cake flour
• 2 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp fine sea salt
• 1/2 tsp freshly grated nutmeg (or 1/4 tsp ground)
• 3/4 cup (150 g) granulated sugar
• 3 large egg yolks (about 54 g)
• 1 cup (240 g) full‑fat sour cream, at room temperature
• 4 tbsp (57 g) unsalted butter, melted and cooled
• 2 tsp pure vanilla extract

Vanilla Glaze

• 3 cups (360 g) powdered sugar, sifted
• 6–8 tbsp (90–120 ml) whole milk, plus more as needed
• 2 tsp pure vanilla extract
• Pinch fine sea salt

For Frying

• Neutral oil (canola, peanut, or vegetable), about 2 quarts (1.9 L), enough for 2–3 inches depth

Step-by-Step Instructions

Step 1: Measure and prep

Line two sheet pans with parchment and top one with a wire rack. Set out a deep, heavy pot (5–6 qt) and a clip-on thermometer. Lightly dust a third piece of parchment (about 12×12 in) for rolling later. Bring sour cream and eggs to room temp (about 15 minutes).

Step 2: Mix the dry ingredients

In a large bowl, whisk together cake flour, baking powder, baking soda, salt, and nutmeg until well combined. This ensures even leavening and that signature craggy rise.

Step 3: Whisk the wet ingredients

In a separate bowl, vigorously whisk sugar, egg yolks, and vanilla until the mixture lightens in color, 1–2 minutes. Whisk in sour cream until smooth, then slowly whisk in the cooled melted butter.

Step 4: Make and chill the dough

Scrape the wet mixture into the dry. Using a stiff spatula, fold until no dry streaks remain; the dough will be soft and sticky but hold together. Cover the bowl and refrigerate for 1 hour to firm up. This chill is essential for clean cuts and to prevent excessive oil absorption.

Step 5: Roll and cut

Turn dough onto the floured parchment. Dust the top lightly and roll to 1/2 inch (1.3 cm) thickness. Using a 3-inch donut cutter with a 1-inch center, cut 12 donuts, dipping the cutter in flour as needed. Gather scraps gently, press together, rest 5 minutes, then re-roll and cut again. For extra cragginess, lightly score a shallow 1/8-inch ring around the top of each donut with a paring knife—do not cut through.

Step 6: Heat the oil

Pour 2–3 inches of neutral oil into the pot and heat to 325°F (163°C). Keep a steady 325–330°F during frying; adjust the burner as needed. Prepare a spider or slotted spoon and the rack-lined sheet pan for draining.

Step 7: Fry to golden-crackly

Fry 3–4 donuts at a time, taking care not to crowd. Cook 1 1/2 to 2 minutes per side until deep golden brown and the scored ring splits into craggy ridges. The holes fry in about 1–1 1/2 minutes total. Maintain oil temperature and skim any crumbs between batches. Transfer donuts to the rack to drain and cool for 5–7 minutes before glazing.

Step 8: Make the vanilla glaze and dip

Whisk powdered sugar, 6 tbsp milk, vanilla, and a pinch of salt until smooth and pourable. The glaze should ribbon off the whisk and level out in 5–7 seconds; add milk by the teaspoon if too thick or a little more powdered sugar if too thin. Dip the warm (not hot) tops of each donut, letting excess drip back into the bowl. Set on the rack to dry 15–20 minutes until the glaze is shiny and sets with a delicate crackle.

Pro Tips

• Use cake flour for the classic tender, cakey crumb. If using all-purpose, replace 2 tbsp per cup with cornstarch and whisk well.
• Keep oil at 325–330°F. Too hot and the crust darkens before the center cooks; too cool and the donuts absorb oil.
• Chill the dough fully. A firm dough cuts cleaner and fries with higher ridges.
• Score a shallow ring on top before frying to encourage those signature cracks.
• Glaze while donuts are warm so it adheres, but not hot or it will slide off.

Variations

• Maple-Brown Butter Glaze: Swap milk for 6 tbsp maple syrup; brown 2 tbsp butter and whisk in with a pinch of cinnamon.
• Chocolate Glaze: Whisk 1/3 cup Dutch cocoa into the powdered sugar; add milk to loosen and finish with 1 tsp espresso powder.
• Spiced Vanilla: Add 1/2 tsp cinnamon and 1/8 tsp cardamom to the dry ingredients for warm bakery vibes.

Storage & Make-Ahead

Best the day they’re made. Store glazed donuts uncovered at room temperature for up to 8 hours, then loosely cover for up to 24 hours. For longer storage, freeze unglazed donuts up to 2 months; thaw at room temperature, warm 5–7 minutes at 300°F (150°C), then glaze. Dough can be made, covered, and refrigerated up to 24 hours; roll, cut, and fry cold dough straight from the fridge.
