Root Beer Float cupcakes

I tried making a new cupcake for the Blue and Gold Banquet the other night. I know I should never do this, but I did it anyway. I made three, yes three batches of the cupcakes. I know they are heavier than regular cupcakes, but I just could not get them right. I think I saw my friend Becky has made them. Becky, what is the secret for the cupcake? The frosting turned out fabulous, but I ended up not taking them to the banquet. I just frosting the sunken treasures and we enjoyed them at home. They really were yummy. I will try and get it figured out. In the meantime, I will just make white cupcakes and frost them with the root beer frosting!
