HEAVENLY CANDY BAR CAKE

Steps:

• Melt candy bars and butter in a heavy saucepan over low heat about 5 minutes, stirring until smooth. Set aside.
• Beat sugar and shortening at medium speed with an electric mixer about 3 minutes or until well blended. Add eggs, 1 at a time, beating just until blended after each addition.
• Combine flour and salt. Stir together buttermilk and baking soda. Gradually add flour mixture to sugar mixture, alternately with buttermilk mixture, beginning and ending with flour mixture. Beat at low speed just until blended after each addition. Stir in melted candy bar mixture and vanilla. Spoon batter into 3 greased and floured 9-inch cakepans.
• Bake at 350° for 30 minutes or until a wooden pick comes out clean. Cool in pans on a wire rack 10 minutes; remove cakes from pans, and let cool completely on wire rack. Spread half of Chocolate-Marshmallow Frosting evenly between cake layers. Spread remaining frosting evenly over top and sides of cake. Garnish, if desired.
• For chocolate marshmallow frosting: Melt first 4 ingredients in a 2 quart saucepan over medium low heat, stirring constantly, until mixture is melted and smooth.
• Transfer chocolate mixture to a large bowl. Place bowl into a larger bowl filled with ice and water. Gradually add powdered sugar alternately with 4 tablespoons milk, beating at low speed with an electric mixer until blended after each addition. Increase speed to medium high, and beat 5 minutes or until frosting is cool, thick, and spreadable, adding up to 2 tablespoons additional milk, if necessary, for desired consistency. Stir in vanilla. Use immediately.
