Easy Red Velvet Cake

This is made from a cake mix and my mother says it is very good and hard to tell it isn't made from scratch.

Ingredients:

1 pkg fudge marble cake mix
1 tsp baking soda
2 eggs
1 1/2 cups buttermilk
1 bottle (1 ounce) red food coloring
1 tsp vanilla

Directions:

1. In mixing bowl, combine cake mix and baking soda.
2. Add eggs, buttermilk, food coloring, and vanilla and blend on low until moistened,
3. Beat on high for 2 minutes.
4. Bake in 2 greased and floured (9 inch) cake pans at 350 for 30-35 minutes.
