Milk Stout Cake with Bourbon Caramel Icing

This cake pulls on the flavors from an old barroom classic – ever tried an Irish Car Bomb? We used the deep caramelly flavors from a milk stout to add dimension to chocolate cake, and we punched it up with a bourbon caramel buttercream. If you like, salty mini pretzels will balance the sweetness of this cake and add an unexpected twist.
