These chocolate glazed cake donuts are baked, soft, and rich with cocoa flavor. Made with buttermilk, sour cream, and a touch of cornstarch for ultimate tenderness, they're dipped in a thin glaze that sets beautifully. A homemade treat that's simple, satisfying, and bakery-worthy.

Ingredients

For the donuts:

  • 5 tbsp salted butter melted
  • 1 cup granulated sugar
  • 2 tsp vanilla extract
  • ½ cup buttermilk room temperature
  • cup full-fat sour cream
  • 1 egg + 1 egg yolk room temperature
  • 1 ½ cups all-purpose flour
  • 1 tbsp corn starch
  • cup unsweetened natural cocoa powder
  • 1 ½ tsp baking powder
  • ½ tsp kosher salt
  • 3 tbsp whole milk room temperature

For the glaze:

  • 2 cups powdered sugar
  • 3-5 tbsp whole milk
  • 1 tsp vanilla extract
  • 1 tbsp melted butter optional but adds shine

Instructions

For the donuts:

  • Preheat oven to 350°F (175°C) and lightly grease a donut pan. In a large bowl, whisk together melted butter, sugar, vanilla, buttermilk, sour cream, egg, egg yolk, and milk until smooth and fully combined.
  • In a separate bowl, sift together flour, cornstarch, cocoa powder, baking powder, and salt. Add the dry ingredients to the wet ingredients and stir until just combined—don’t over mix.
  • Pipe or spoon the batter into the donut pan, filling each cavity about ¾ full. Bake for 12–14 minutes, or until a toothpick inserted into the center comes out clean. Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before glazing.

For the glaze:

  • In a medium bowl, whisk together powdered sugar, milk, vanilla, and melted butter until smooth. Dip each cooled donut into the glaze, or pour over with a pan underneath, then return to the wire rack to set for 15–20 minutes.
    Optional: Add sprinkles, mini chocolate chips, or flaky sea salt while the glaze is still wet.
