Red velvet cake is a red cake with delicate chocolate favor. The buttermilk, vanilla, vinegar and cocoa give this delicious cake it's distinctive flavor.
Lightly grease and flour two 9 inch cake pans. Set them aside.
In large mixing bowl, cream shortening and sugar together well. Beat in eggs until light and fluffy. Add salt. Beat in cake flour alternately with buttermilk. Make a paste of red food coloring and cocoa. Add it to the batter and beat well. Mix vanilla, baking soda and vinegar in a small bowl. Sprinkle over the batter, then stir in.
Pour into the prepared pans. Bake for 30 to 35 minutes or until done when inserted with a toothpick. Cool in pans for 10 minutes. Turn out on to wire racks and let cool completely.
To prepare the vanilla frosting, combine the flour and milk in a small saucepan. Beat with a whisk until the mixture is smooth. Stir constantly over low heat until thickened. Cool. In medium bowl, cream sugar and butter or margarine. Add vanilla. Beat in cooled flour/milk mixture until frosting is fluffy and resembles whipped cream.
Frost between layers of the cooled cake, then frost the side and top of the cake.
