When the cake is about half-way through cooking, prepare the frosting.
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.
Enjoy!
