Trip to Graceland So it took a while, but we've finally perfected the long awaited Elvis inspired cupcake. Much like the King himself, it's decadent, it's delicious, and it might induce shock to the system. Eat in small doses. Chunky peanut butter cake, layered with a light banana cream frosting, rolled in applewood smoked bacon, and drizzled with honey. Available June through September.
