I honestly haven't tried them yet. I started them last night, but was running a low grade fever so put the cupcakes away to frost today. I made the icing today while making dinner (meatloaf, yum) and then had to rush my son to Boy Scouts. I will try tonight!
10/29/08 - 9:20 a.m.: I had put these in Tupperware in the fridge last night. After scouts, Jimmy and I tried them. They were delicious!
1 stick of butter, softened
1 T vanilla
1 3/4 cup powdered sugar
1/8 cup whipping cream
Whip butter until fluffy. Mix in vanilla. Alternate mixing in powdered sugar and whipping cream until the icing is fluffy and smooth - this could take several minutes. Use an icing bag top pipe icing into cupcakes.
