Chocolate cake is great. But, what happens when you are out of eggs? This is what happens.
Mayonnaise replaces the eggs and butter and makes a moist delicious cake.

Preheat your oven to 350 degrees Fahrenheit.
You will need a 9″x13″ baking pan. Grease and flour it.


1/3 cup cocoa powder
1 cup boiling water
1 teaspoon vanilla extract
3/4 cup mayonnaise
2 cups cake flour
1 cup sugar
2 teaspoons baking soda
1/2 teaspoon salt

In a medium bowl, whisk together the cocoa powder and water. Cool to room temperature.
Whisk in the vanilla extract and the mayonnaise. Set aside.
In a large mixing bowl, blend the flour, sugar, baking soda, and salt.
Add the cocoa mixture. Mix with a mixer on low speed until everything is moistened. Increase the speed to medium and beat for 1 minute. Use high speed with a hand mixer.
The batter may seem thin. That is OK.
Pour the batter into the baking pan.
Bake for 40-45 minutes or til a toothpick comes out clean when poked into the center of the cake.
Cool on a wire rack.
Frost as desired.

If you want to you can use all-purpose flour. If you do only use 1-3/4 cup all-purpose flour instead of the 2 cups cake flour.
