Ingredients
 
 

Chocolate Cake

Chocolate Mascarpone Frosting

  • 113 grams unsalted butter softened
  • 227 grams mascarpone cheese room temperature
  • 360 grams powdered sugar
  • 30 grams cocoa powder
  • 1 teaspoon vanilla extract

Instructions
 

Chocolate Cake

  • Preheat the oven to 350°F/180°C. Line 3 6-inch cake pans with parchment paper.
  • Whisk cocoa powder and hot coffee together in a large bowl until there are no lumps. This blooms the cocoa powder for more flavor.
    75 grams dutch processed cocoa powder, 200 grams brewed coffee
  • Add the oil, sugar, eggs, and sour cream. Whisk vigorously until combined.
    120 grams vegetable oil, 280 grams granulated sugar, 2 large eggs, 240 grams sour cream
  • Fold the flour, baking powder, baking soda, and salt into the wet ingredients with a rubber spatula until the last streak of flour disappears.
    160 grams all purpose flour, 1 ½ teaspoon baking powder, ¾ teaspoon baking soda, ½ teaspoon salt
  • Pour the cake batter evenly into the prepared pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean with a few moist crumbs.
  • Remove from the oven and let cool in the pans for 10 minutes. Loosen the sides with a butter knife and turn them over on a wire rack to cool completely for 35-40 minutes.

Chocolate Mascarpone Frosting

  • In the bowl of an electric hand mixer or stand mixer with the paddle attachment, cream unsalted butter and mascarpone cheese together on medium speed until smooth.

  • Gradually add the powdered sugar 1 cup at a time, mixing on low speed. Scrape down the sides of the bowl as needed.
    360 grams powdered sugar
  • Once fully combined, mix in the cocoa powder and vanilla on low speed. Increase the speed to medium until the frosting is smooth and creamy.
    30 grams cocoa powder, 1 teaspoon vanilla extract

Assembly

  • Place a cake layer on a cake stand or serving platter and spread ½ cup frosting on top. Repeat with a second layer.
  • Place the last layer on top with the bottom (flat side) up. Spread a thin layer of buttercream (crumb coat) on top and down the sides of the cake.
  • Place the crumb-coated cake in the refrigerator to chill for 20 minutes or until the frosting is firm and dry.
  • Apply a final coat of frosting. Decorate with piping, chocolate chunks, or a drizzle of melted chocolate. Enjoy!
