Margarita Cupcakes

After making the swiss buttercream a few weekends ago, I thought I would try to make some margarita cupcakes.  Basically it's just a white cake with lime zest and lime juice.  The frosting was similar to the buttercream but with lime and tequila.  I fear I did not use enough tequila and it turned out to be more like a key lime cupcake.
Also, I purchased some pastry bags and tips for decorating.  I also bought super cute cupcake wrappers.  I had just a tiny bit of fun with it.  Next time,  I think I may practice with dyed frosting.  I have some ideas!
