Ingredients

Makes 12

• 3/4 cup unsweetened cocoa powder
• 3/4 cup all-purpose flour
• 1/2 teaspoon baking powder
• 1/4 teaspoon salt
• 3/4 cup (1 1/2 sticks) unsalted butter, room temperature
• 1 cup sugar
• 3 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup sour cream
• Easy White Icing
• Sprinkles (optional)

Directions

1. Preheat oven to 350 degrees. Line 12-cup standard muffin tin with paper liners.
2. Into a medium bowl, sift together cocoa, flour, baking powder, and salt; set aside. In a mixing bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each, then beat in vanilla. With mixer on low speed, add flour mixture in two batches, alternating with sour cream and beginning and ending with flour.
3. Pour batter into cups, filling each 3/4 full. Bake until a toothpick inserted in centers comes out clean, 20 to 25 minutes.
4. Cool in pan 5 minutes; transfer to a wire rack to cool completely, then spread with Easy White Icing using a table knife or small offset spatula. Decorate with sprinkles, if desired.

Frosting:

Ingredients

Makes 5 cups

• 4 large egg whites
• 1 1/4 cups sugar
• 1 1/2 cups (3 sticks) unsalted butter, room temperature, cut into tablespoons
• 1 teaspoon pure vanilla extract
• 1 1/2 cups (12 ounces) strawberry jam, pureed in a food processor

Directions

1. In the heatproof bowl of an electric mixer set over a saucepan of simmering water, combine egg whites and sugar. Cook, whisking constantly, until sugar has dissolved and mixture is warm to the touch (about 160 degrees).
2. Attach the bowl to the mixer fitted with the whisk attachment. Beat the egg-white mixture on high speed until it holds stiff (but not dry) peaks. Continue beating until the mixture is fluffy and cooled, about 6 minutes.
3. Switch to the paddle attachment. With mixer on medium-low speed, add butter several tablespoons at a time, beating well after each addition. (If frosting appears to separate after all the butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Beat on lowest speed to eliminate any air bubbles, about 2 minutes. Stir in strawberry jam with a rubber spatula until frosting is smooth.
