- If you boil the butter/cocoa/milk mixture too long or too hard the frosting will be hard and yucky.
- If you fail to keep the cake properly covered after you frost it the frosting will get hard and crack when you cut it.
- The frosting sets up REALLY fast (that's a good thing because it keeps it from running off the cake altogether) so you can't use sprinkles or anything like that. Just frost it and leave it alone.
CHOCOLATE FROSTING
1 cube butter
4 Tbsp. cocoa
1/3 cup evaporated milk
4 cups powdered sugar
Melt butter over LOW heat. Whisk in cocoa and milk. Bring mixture JUST to a boil over low heat, stirring constantly. Remove from heat at the first sign of bubbles. Beat in sugar until thick and smooth. Pour warm frosting over warm cake for best results. (And it tastes the best when the cake is still warm too...yum!)
NOTE: I haven't tried this recipe with margarine so I don't know how it might turn out.
