1.5 cups buttermilk

1 oz food coloring red
1 cup sugar
1 teaspoon vanilla extract

18.3 oz fudge marble cake mix

Directions
Combine dry cake mix, fudge marble packet and baking soda in a medium bowl; add remaining ingredients. Blend with an electric mixer on low speed until moistened. Beat on high speed for 2 minutes.
Pour batter into 2 greased and floured 9" round cake pans.
Bake at 350 for 20 to 35 minutes or until toothpick inserted into center of cake comes out clean. Cool in pans for 10 minutes; turn out onto a wire rack. Cool completely; if desired, freeze layers overnight to make cake easier to frost.
Spread vanilla frosting between layers and on top and sides of cake.
Whisk flour and milk in a saucepan over medium-low heat until smooth. Bring to a boil; cook and stir for 2 minutes or until thickened. Cover and refrigerate until chilled.
In a medium bowl, blend butter and sugar; add chilled milk mixture. Beat for 8 minutes or until fluffy; stir in vanilla.
