Devil's Food Cupcakes with Orange Flavored Frosting

Martha Stewart Cupcakes with Ina Garten Frosting.

Ingredients:
Cupcakes:
3 ounces unsweetened chocolate, chopped
1 teaspoon baking soda
1/2 cup boiling water
1 cup (2 sticks) unsalted butter, room temperature
2 cups sugar
5 large eggs
3 cups all-purpose flour
3/4 cup buttermilk
1 teaspoon pure vanilla extract

Frosting:
8 ounces cream cheese, at room temperature:
1/4 pound (1 stick) unsalted butter, at room temperature:
1/2 teaspoon orange zest:
1/2 teaspoon pure vanilla extract:
1/2 pound confectioners' sugar, sieved:
Orange food coloring (or red and yellow), optional

Directions:

Heat the oven to 350 degrees. Line the bottom of two 12-cup muffin tins with paper liners.

Melt chocolate in a double boiler over simmering water. In a bowl, stir baking soda into the boiling water; stir this mixture into chocolate. Set aside to cool slightly.

Using an electric mixer, cream butter and sugar until the mixture is light and pale yellow in color. Add eggs, one at a time, and continue to mix until thoroughly incorporated. Add flour and buttermilk, alternating between small amounts of each, and blend well.

Add the melted chocolate and vanilla to the batter, and stir well. Pour the batter into the paper cups, and bake until a cake tester comes out clean when inserted into the center of a cupcake, about 30 minutes. Remove cupcakes from the oven, and allow them to cool briefly in the muffin tin before removing them to a wire rack to cool completely. 

For the frosting, mix the cream cheese, butter, orange zest and vanilla in the bowl of an electric mixer fitted with the paddle attachment until just combined. Add the sugar and mix until smooth.
When the cupcakes are cool, frost them generously.
