  • 7 ounces bittersweet chocolate, finely chopped, divided
  • 1/2 cup heavy cream
  • 1/2 cup plus 2 tablespoons sour cream, divided
  • 1/3 cup hot coffee
  • 1 cup (7 ounces) granulated sugar
  • 1/3 cup canola oil
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 3/4 cup (3 3/4 ounces) all purpose flour
  • 1/2 cup cocoa
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder


  1. 1

    Adjust oven rack to middle position and preheat to 350°F. Melt 6 ounces chocolate and cream in heatproof bowl over a pan of barely simmering water, and stir until mixture is melted and smooth. Remove from heat and whisk in 2 tablespoons sour cream. Set frosting aside to thicken while cupcakes are prepared.

  2. 2

    Line cupcake pan with paper liners. Place remaining 1 ounce chocolate in large bowl and stir in hot coffee to melt. Whisk in remaining 1/2 cup sour cream, sugar, oil, egg, and vanilla until combined. Add flour, cocoa, salt, baking soda, and baking powder to the bowl and then whisk until smooth.

  3. 3

    Divide batter between cups and bake until center is just firm, about 17 minutes. Let cupcakes cool in pan for 5 minutes, then transfer to cooling rack. When completely cool, top with chocolate frosting.
