11. 11Add milk, cocoa and butter to a saucepan. Bring mixture to a boil.
12. 12Once boiling, remove it from the heat and stir in powdered sugar. I like to beat the mixture with my hand-held mixer to get rid of any lumps.
13. 13Pour hot icing over hot cake. Use a spatula to spread it evenly over the cake. Allow frosting to set for about 10 minutes before eating.
