1 pkg. cake mix with pudding in the mix
1 c. water
3 eggs
1 c. light mayonnaise

Grease and flour 2 (9") layer cake pans, or make into sheet cake. In large bowl mix at low speed, all ingredients for 30 seconds. At medium speed, mix for 2 minutes or 300 strokes by hand. Pour into prepared pan or pans. Bake at 350 degrees for 30 to 35 minutes or until cake springs back when lightly touched in center. Cool in pan for 10 minutes. Remove; cool on wire racks. Frost as desired. This is especially good with a chocolate cake mix, with fudge frosting.

If using a cake mix without the pudding in the mix, reduce mayonnaise to 1/2 cup and increase water to 1 1/3 cups.
