These Beer Mug Cupcakes with Baileys® Filling are a fun treat for any party. They're so good, your guests will toast to their deliciousness! Each triple chocolate cake is filled with decadent Baileys® Irish Cream chocolate ganache, then wrapped in white modeling chocolate decorated to look like a beer mug, and topped with a frothy whipped cream foam. These festive cakes can be served for many occasions including: St. Patrick's Day, 21st birthday parties, game day gatherings, and even backyard barbecues. I used triple chocolate cake mix and half-pint Mason jars to bake the cupcakes. The Mason jars make taller cupcakes that mimic a beer mug shape. Before you do anything though, grab some non-stick cooking spray (preferably the kind with flour) and give each of your jars a really good spray. Do not skip this step or your cakes will stick – and that would be a bummer. Cake crumbs don't make good beer mugs. When removing the center of the cupcakes to fill with ganache, use a cupcake plunger/corer, apple corer or a knife. I used a cupcake corer first, then a knife to cut out some more from each cake. You'll have lots of scraps leftover, so enjoy a little snack before making your modeling chocolate wrappers. Cheers! Or should I say, bon apetit? Either way, it's delicious!
