I used Allyson's yellow cake recipe and I used my own Chocolate frosting, in a word: AMAZING!
1 cup softened butter
4 ½ cups confectioners' sugar
1 ¼ cups baking cocoa
½ teaspoon vanilla extract
½ cup milk
1. In a large mixing bowl, cream butter. Gradually beat in confectioners' sugar, cocoa and vanilla. Add enough milk until frosting reaches spreading consistency.
After I made the frosting I coarsely chopped up Pecans, applied the frosting to the middle layer, and then sprinkled with Pecans. Then I added the top layer of cake, frosted, and topped with more pecans as well as coarsely chopped milk chocolate chips. The pecans added an amazing flavor, Sam's only request was to add more next time.
