These Shamrock Shake Cupcakes are great for your early morning St. Patrick's Day hangover! Their convenient straw can also be used for your St. Patty's day shots. These little leprechaun cupcakes are made with a simple cupcake mix that has been hit with a splash of green creme de menthe (a sweet mint flavored alcoholic beverage). Just like its familiar friend the Irish Car Bomb, the dessert is also topped off with a fresh white buttercream.  (Thx BakingJunkie)
