Ingredients
  

  • All-purpose flour – The backbone of the dough; provides structure.
  • Granulated sugar – Sweetens and helps with browning.
  • Baking powder – Main leavener for lift.
  • Baking soda – Reacts with the sour cream for extra tenderness.
  • Kosher salt – Balances sweetness and sharpens flavors.
  • Freshly grated nutmeg (optional but classic) – Gives that unmistakable old-fashioned donut note.
  • Unsalted butter – Adds richness and a delicate crumb.
  • Large eggs – Bind the dough and contribute to texture.
  • Vanilla extract – Rounds out the flavor.
  • Full-fat sour cream – The star; adds moisture, tang, and tenderness.
  • Neutral oil for frying (like canola or peanut) – Clean flavor and high smoke point.
  • Powdered sugar
  • Milk or cream
  • Vanilla extract
  • Pinch of salt

Instructions
 

  • Mix the dry ingredients. In a bowl, whisk 3 1/2 cups all-purpose flour, 1 cup sugar, 2 teaspoons baking powder, 1/2 teaspoon baking soda, 1 teaspoon kosher salt, and 1/2 to 3/4 teaspoon freshly grated nutmeg.
  • Cream the butter and eggs. In a separate large bowl, beat 4 tablespoons softened butter with 2 large eggs and 2 teaspoons vanilla until smooth. It won’t get fluffy like cake batter—that’s fine.
  • Add the sour cream. Fold in 1 cup full-fat sour cream until fully combined. The mixture should look thick and creamy.
  • Bring it together. Add the dry ingredients to the wet mixture in two additions. Stir gently until no dry spots remain. The dough will be soft and slightly sticky.
  • Chill. Scrape the dough onto a lightly floured sheet of parchment. Pat into a 1/2-inch-thick slab, cover, and chill for at least 1 hour (or up to overnight). Chilling helps the donuts keep their shape and fry evenly.
  • Heat the oil. In a heavy pot, heat 2–3 inches of oil to 350–360°F (175–182°C). Use a thermometer for accuracy.
  • Cut the donuts. Flour your surface and a rolling pin. Roll the chilled dough to about 1/2 inch thick. Cut with a 3-inch donut cutter (or use a 3-inch and 1-inch round cutter). Reroll scraps once if needed.
  • Fry in batches. Carefully slide donuts into the hot oil, 3–4 at a time. Fry about 1–1 1/2 minutes per side, until deep golden with a crisp edge. Keep oil between 350–360°F; adjust heat as needed.
  • Drain. Use a slotted spoon to transfer donuts to a wire rack set over a sheet pan. Let cool 5–10 minutes before glazing.
  • Make the glaze. Whisk 2 cups powdered sugar, 3–4 tablespoons milk or cream, 1 teaspoon vanilla, and a small pinch of salt until smooth and pourable. Adjust with more milk or sugar as needed.
  • Glaze. Dip each warm donut top into the glaze, let excess drip off, then return to the rack. For a classic finish, dip twice, letting the first coat set slightly before the second.
  • Optional: Bake instead of fry. For a lighter take, pipe the dough into greased donut pans and bake at 350°F (175°C) for 12–15 minutes, until set and lightly golden. Texture will be more cakey and less crisp.
