I forgot to include this in my cupcake post and was reminded when Lynn at SCS left a very nice comment. I don't have a lot of time for cooking so I am a big fan of semi-homemade stuff ala sandra lee. I saw a show where she added a teaspoon of vanilla to a can of store bought frosting and tried it out. It was a bit better but I came up with my own recipe.
1 can of (your choice of flavor, I like the cream cheese) frosting. I like the Duncan Hines brand myself.
3 ounces marshmallow cream
1 teaspoon pure vanilla
Mix well. It is a bit more runny (and sweeter) than normal frosting but it tastes a little more homemade than directly from the can. Happy Baking!
