Chocolate Mayonnaise Cake

I know this sounds gross, but it's actually really good and VERY moist. My great grandmother used to use mayo in her cakes as well. You don't even get the "mayo" taste.

Ingredients:
1 cup mayonnaise
1 cup white sugar
3/4 cup water
2 cups all-purpose flour
1 1/2 teaspoons baking soda
4 tablespoons unsweetened cocoa powder
1/2 teaspoon salt
2 teaspoons vanilla extract

Directions:
1) Preheat oven to 350 degrees.
2) Grease and flour two 8 or 9 inch round cake pans.
3) Sift all-purpose flour, salt, baking soda, and cocoa together.
4) Whip mayonnaise, white sugar, cold water, and vanilla together until mixed thoroughly.
5) Add flour mixture slowly and beat at medium speed of an electric mixer for 2 minutes.
6)Pour batter into cake pan.
7) Bake at 350 degrees for 20 to 25 minutes. Frost with your favorite frosting.
