My Dark Chocolate Rum Cupcakes with Salted Caramel Buttercream recipe was inspired by the most popular dessert on this year’s Halloween Office Party Buffet.  There sat Mark’s picture perfect rum cake, whose aroma alone was so intoxicating co-workers began to stalk the break room pre-party (secretly wondering if they could manage to sneak a piece without getting caught). There’s something sensual about the combination of rum and butter and sugar.
