So for my margarita cupcakes I took the traditional route as well. They have a pinch more salt than the average cupcake, just to help kick up the maragarita flavor, and they're made with Bacardi Margarita mix. I top them with a light green lime meringue butter cream, a jelly lime slice, and a dusting of glitter sugar (it didn't show up well on the pictures).
I promise you one bite and you are on the beach with your Margarita in hand. Don't be surprised if you have sand in your shoes, by the time you finish your cupcake!
BTW- These are minis!
