Necessity is the mother of invention. So is running out of an ingredient halfway through making a dish. The end result was worth keeping. This is one of the best chocolate frostings I've ever made. Try it out for yourself.
Luscious Chocolate Marshmallow Frosting
1/2 c. butter, softened
2 c. powdered sugar
1/3 c. cocoa powder
1 7 oz jar marshmallow creme
1/2 t. vanilla
2-4 T. milk
pinch of salt
Cream butter until fluffy. Add powdered sugar and cocoa powder. Stir on low speed until mixed. Add the marshmallow creme, vanilla, salt, and 2 T. of milk. Beat on low until blended, then turn speed to high. If the frosting is too dry, add more milk a teaspoon or two at a time. You want a soft, fluffy frosting that doesn't drip. If you get it too runny, add a little more powdered sugar.
Whip on high speed for at least 3 minutes.
