Cake: 1) Beat sugar and eggs with electric mixer in a large bowl until it reaches the top of the bowl. 2) Blend in flour with a spatula. 3) Line round cake pans with waxed paper and pour batter into each - just enough batter to cover the bottom. It should be very thin. 4) Bake each cake just a few minutes, until cooked, in a 350 degree oven. Repeat until there are 7 layers. Icing: 1) Mix the butter, powdered sugar, cocoa powder, and coffee until spreadable. 2) Add milk if it's too thick. 3) Spread icing between each layer of cake and around the outside.
