3.9 from 11 reviews

These Chocolate Old-Fashioned Donuts offer a rich, moist cake donut experience infused with black cocoa powder for intense chocolaty flavor. Unlike typical yeast donuts, these old-fashioned style donuts are dense and cakey, fried to golden perfection, then dipped in a smooth powdered sugar glaze that hardens to a perfect crust. Best enjoyed the next day as the glaze soaks into the donuts, enhancing moisture and flavor.

Ingredients

Donut Dough

  • 1/2 cup granulated sugar (100g)
  • 3 tablespoons butter, room temperature
  • 2 large egg yolks
  • 2 cups cake flour (226g)
  • 1/2 cup black cocoa powder (40g)
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • 1 cup sour cream (230g)
  • Canola or peanut oil (for frying)

Glaze

  • 3 1/2 cups powdered sugar (350g)
  • 1/3 cup hot water (78g)
  • 1 1/2 teaspoons corn syrup
  • 1/2 teaspoon vanilla extract
  • 1/4 teaspoon kosher salt

Instructions

  1. Do Ahead: These donuts improve after sitting for a day as the glaze hardens and moisture from the glaze soaks in, keeping the donuts moist. They can be made a couple of days in advance.
  2. Prepare Butter: Bring the butter to room temperature for easy mixing.
  3. Prepare Parchment Squares: Cut parchment paper into 4-inch squares and place them on baking sheets for placing cut donuts before frying.
  4. Set up Draining Station: Arrange a large baking sheet with layers of paper towels and a wire rack on top to drain donuts after frying.
  5. Make Donut Dough: In a stand mixer bowl or large bowl, beat granulated sugar and butter until sandy in texture. Add egg yolks and beat until mixture is lighter in color and thicker. In a separate bowl, whisk together cake flour, black cocoa powder, baking powder, and kosher salt. Add dry ingredients to wet in three parts, alternating with sour cream, finishing with the dry ingredients. The dough will be sticky.
  6. Chill Dough: Optionally, grease a large bowl and line it with plastic wrap pieces arranged crosswise and greased. Place the sticky dough in the bowl, cover gently with overhanging plastic wrap, and chill for at least 1 hour or up to overnight.
  7. Roll and Cut Donuts: Generously flour a clean countertop. Unwrap chilled dough and transfer onto floured surface. Flour the top and rolling pin, then roll dough to approximately 1/2 inch thick. Using a 3-inch round cutter and a 1 1/4-inch cutter for the hole, cut out donuts, flouring cutters between uses. Re-roll scraps as needed.
  8. Place Donuts on Parchment: Arrange the cut donuts and donut holes on prepared parchment squares placed on sheet pans. Each parchment square can hold 4-5 holes.
  9. Heat Oil for Frying: In a heavy-bottomed pot or Dutch oven, fill with two inches of canola or peanut oil. Heat to between 325°F and 340°F. Keep a thermometer handy as temperature may fluctuate with added donuts.
  10. Fry Donuts: Lift donuts by the parchment square and gently lower them into the hot oil. Fry a few donuts at a time without overcrowding. Fry the donuts for 2 minutes on the first side, flip, and fry 1 minute 30 seconds on the second side. Remove and place on prepared draining rack. Fry donut holes for 1 minute per side.
  11. Make the Glaze: In a large bowl, whisk together powdered sugar, hot water, corn syrup, vanilla extract, and kosher salt until smooth.
  12. Glaze the Donuts: Dunk fried donuts into the glaze, use chopsticks or fork to turn and drain excess glaze, then place on wire rack to allow glaze to harden completely.

Notes

  • Donuts taste better the next day after the glaze hardens and moisture soaks into the cake.
  • Butter should be softened to room temperature for easier mixing.
  • Carefully monitor oil temperature between 325°F and 340°F for optimal frying.
  • Do not overcrowd the frying pot to ensure even cooking and proper oil temperature.
  • Use canola or peanut oil for frying as they have high smoke points and neutral flavor.
  • Greasing and lining a bowl with plastic wrap helps when chilling the sticky dough.
