Ingredients

butter

black cocoa

Cake:

2 cups flour

1/3 cup unsweetened cocoa

1/3 cup black cocoa [available from specialty retailers]

1 1/4 teaspoons baking soda

1/4 teaspoon baking powder

3 eggs

1 2/3 cups sugar

1 teaspoon vanilla

1 cup Hellmann’s/Best Foods mayonnaise

1 1/3 cups fresh cold water

Buttercream frosting:

2 cups butter, softened

1 cup heavy whipping cream

1 cup confectioners’ sugar

1/3 cup black cocoa

1/4 cup dutch process cocoa

In a large bowl, Whip the butter on high speed, occasionally scraping down the sides of the bowl.

Whip until double in volume. This takes a very long time, approximately 10 minutes.

While still whipping, drizzle in the heavy cream.

Continue whipping until the mixture is stiff, approximately 2 to 4 minutes.

In a medium bowl, carefully combine, with a whisk, the confectioners’ sugar, the black cocoa,

and the dutch process cocoa. Add 1/2 of the confectioners’ sugar mixture to the butter and cream mixture and whip until smooth. At this point, you can taste the frosting and determine

if you would like to add more of the sugar mixture to sweeten to taste.
