Icing
1 sick butter melted
1/3 C. cocoa
6 tsp. pet milk
1 box powered sugar
1 tsp. vanilla
Icing needs to be thin enough to be poured over cake in order to get it without messing up the marshmallow creme. Add a little extra milk if necessary. Sprinkle with chopped pecans over the top.
I made this cake yesterday and it was yummy. I used a table knife to pull the marshmellow creme to edges and spread on top; it worked well.
