Chocolate Mayonnaise Cake

2 cups flour

2/3 cup unsweetened cocoa powder

1 ¼ tsp baking soda

¼ tsp baking powder

3 large eggs

1 2/3 cup sugar

1 tsp vanilla

1 cup mayonnaise

1 1/3 cup cold water

Heat oven to 350.  Butter and flour two 9-inch round pans.  Sift dry ingredients together.  In a large bowl with electric mixer, beat eggs, sugar and vanilla for 3 minutes, reduce speed and add mayonnaise.  Using wooden spoon stir in dry ingredients one-third at a time alternating with water, beginning and ending with flour mixture.  Divide the batter evenly into the two pans, bake for about 30 minutes.  Cool cake on rack. 

Note:  I use my chocolate icing recipe for this cake.
