Sift sugar and cocoa together into a large bowl. In another bowl, combine 1 cup of sugar mixture with butter and 1 tablespoon cream, beating until smooth.
Add another cup of sugar and another tablespoon of cream, beating well. Continue until all ingredients are combined and the frosting is fluffy. Beat in vanilla.
Spread frosting on top of one round. Place the second layer on top and completely cover the top and sides with frosting.
