I made these for Cinco de Mayo this year. They were absolutely delicious! I used Sauza Margarita Mix with the tequila already in it. It was only $9 for a box, which is equal to a 1.75 L. Very tasty! I also added some lime juice for extra zing! For the frosting, I mixed in a little bit of margarita mix with the cream cheese frosting and added some lime juice. I put it in a ziploc bag so that I could pipe the frosting easily. Be creative and add a little straw, umbrella, or a sugared lime! These are sure to be a hit at any party!
