White Cake

This is my best friend's recipe for white cake. It's the BEST!! I can, by no way, take credit for it, but really need to keep track of the recipe!!

Ingredients
1 box white cake mix
1 cup flour
1 cup sugar
3/4 tsp salt
1 1/3 cup water
1/8 cup oil
1 teaspoon vanilla
1 teaspoon almond extract
1 cup (8 oz) sour cream
4 large egg whites

Directions
Place all dry ingredients in a large mixing bowl and stir together with a whisk. Add the remaining ingredients and beat on a low speed for 2 minutes. Bake at 325 until cake is done -- use box for idea.
