Classic Red Velvet Cake

Directions

1. Preheat oven to 350°. In a large bowl, cream shortening and sugar until light fluffy. Add eggs, one at a time, beating well after each addition. Beat in the food coloring, vinegar, butter flavoring and vanilla. Combine the flour, cocoa, baking soda and salt; add to creamed mixture alternately with buttermilk, beating well after each addition.
2. Pour into three greased and floured 9-in. round baking pans. Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
3. In a large bowl, combine frosting ingredients; beat until smooth and creamy. Spread between layers and over top and sides of cake.
