For the Chocolate Sheet Cake Frosting

  • Add milk, cocoa and butter to a saucepan. Bring mixture to a boil. 
  • Once 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. 
  • Pour 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.


You can store any extra cake covered, in an air-tight container for 2-3 days.
