Dark Chocolate-Raspberry Cakes
- Let butter and eggs stand at room temperature for 30 minutes. Meanwhile, preheat oven to 350 degrees F. Lightly coat twenty-four 2-1/2-inch muffin cups with nonstick cooking spray; set aside.
- In a medium bowl, stir together flour, cocoa powder, baking soda, baking powder, and salt. In a small bowl, combine granulated sugar and brown sugar. Set aside.
- In a large bowl, beat butter with an electric mixer on medium to high speed for 30 seconds. Gradually add sugar mixture, about 1/4 cup at a time, beating on medium speed about 5 minutes or until light and fluffy, scraping side of bowl occasionally. Add eggs one at a time, beating well after each addition. Beat in vanilla.
- Alternately add flour mixture and buttermilk to butter mixture, beating on low speed after each addition just until combined. Beat on medium to high speed for 20 seconds more.
- Divide half of the batter among the prepared muffin cups. Divide the 2 cups raspberries among muffin cups, adding 3 or 4 berries to the center of each cup. Spoon the remaining batter over berries in muffin cups.
- Bake for 18 to 20 minutes or until a toothpick inserted near the centers comes out clean. Cool in pans on wire racks for 5 minutes. Remove cupcakes from pans; cool completely on wire racks.
- Prepare Chocolate Truffle Icing. To glaze cupcakes, invert one cake at a time onto a slotted spoon. Hold the cake over the bowl of icing and spoon icing over cake, allowing excess to drip down side. Place glazed cakes on a wire rack set on a parchment-lined baking sheet. Chill about 20 minutes or until icing is set. If desired, garnish cakes with additional raspberries. Makes 24 cupcakes.
