RED VELVET CAKE WITH MASCARPONE FROSTING

SERVES 8-10

CAKE

1¾ cups all-purpose flour

¼ cup cocoa powder

1 teaspoon kosher salt

1 teaspoon baking soda

½ cup butter, plus more for greasing cake pans

1 cup sugar

2 large eggs

2 teaspoons vanilla extract

2 tablespoons red food coloring

½ cup buttermilk

¼ cup sour cream

1 tablespoon white wine vinegar

FROSTING

8 ounces mascarpone

1 cup heavy cream

¼ cup sugar

One 6-ounce box blueberries

One 6-ounce box raspberries

FOR THE CAKE

PREHEAT the oven to 350°F. Prepare two 9-inch round cake pans by buttering lightly. In a large bowl, sift flour, cocoa powder, salt, and baking soda together and set aside. In a mixer on medium-high, beat butter and sugar with the paddle attachment until light and fluffy, 3–5 minutes. Add the eggs one at a time until they are well mixed. Beat in vanilla and red food coloring until incorporated. In a medium bowl with a wire whisk, beat together buttermilk, sour cream, and vinegar. Alternating in two stages, add the flour mix and the buttermilk mix until just incorporated. Don’t overmix. Divide batter equally between the two pans and bake for around 20 minutes, or until a toothpick inserted in the center of the cake comes out clean. Transfer to a wire rack to cool completely before frosting.

FOR THE FROSTING

IN a mixer on a low-high speed with the paddle attachment, beat the marscapone, cream, and sugar until smooth, around 1 minute. Turn up to medium-high and beat until stiff peaks form, around 1 more minute. Don’t overbeat or frosting will go grainy.

TO ASSEMBLE

PLACE one cake on a serving plate. Add half the frosting and use a small spatula to spread it evenly. Scatter half the blueberries and raspberries. Top with the second cake and smooth the rest of the frosting evenly over the top. Finish with the remaining berries.
