Devil's Food Cake with Chocolate Fudge Frosting

Ingredients
1/2 cup butter, softened
2-1/4 cups packed brown sugar
3 eggs
1-1/2 teaspoons vanilla extract
3 ounces unsweetened chocolate, melted and cooled slightly
2-1/4 cups cake flour
1 teaspoon baking soda
1/2 teaspoon salt
1/2 teaspoon baking powder
1 cup (8 ounces) sour cream
1 cup water

FROSTING:
1/2 cup butter, cubed
4 ounces unsweetened chocolate, chopped
3-3/4 cups confectioners' sugar
1/2 cup whole milk
2 teaspoons vanilla extract

Directions

1. Preheat oven to 350°. Line bottoms of two greased 9-in. round baking pans with parchment paper; grease paper.
2. In a large bowl, cream butter and brown sugar until fluffy. Add eggs, one at a time, beating well after each addition. Beat in vanilla and cooled chocolate. In another bowl, whisk flour, baking soda, salt and baking powder; add to creamed mixture alternately with sour cream and water, beating well after each addition.
3. Transfer batter to prepared pans. Bake 25-30 minutes or until a toothpick inserted in center comes out clean. Cool in pans 10 minutes before removing to wire racks; remove paper. Cool completely.
4. For frosting, in a small heavy saucepan, melt butter and chocolate over low heat. Remove from heat; cool 5 minutes. In a large bowl, beat confectioners' sugar, milk and vanilla until smooth. Gradually add chocolate mixture, beating until light and fluffy. Spread between layers and over top and sides of cake.
