Instructions
Preheat oven to 350°. Grease and flour two deep 8-inch pans for a taller cake. If using the extra cake mix option mentioned above and in the notes, use the two 9-inch round cake pans.
Beat cake mix, mayonnaise, water, and eggs until mixed, then beat with an electric mixer for 4 minutes.
Bake 25-30 minutes or until toothpick inserted in centers comes out clean.
Let cool on a wire rack 10 minutes. Remove cakes from pans and cool completely.
Frost the cake with canned Betty Crocker chocolate frosting.
Notes
Best Foods mayonnaise, sold in the Western USA, is basically the same as Hellman's and also works well.
The box of cake mix is now a smaller size at 13.25 oz. To keep the cake pretty much the same, use 3 medium to large eggs (no larger), 1 cup ice cold water, and only ¾ cup of mayonnaise. Bake cakes in 8x2 inch round pans.
Alternatively, buy a second box of cake mix and add ⅔ cup (3 oz weight) to the recipe, keeping the 3 eggs, 1 full cup of mayonnaise and 1 cup of ice water. This will give you a big, fluffy, 9-inch cake. Also, the extra 3 oz weight of cake mix = 16.25 oz cake mix not 15.25, so there's a little higher ratio of cake mix now, but it worked well for me.
