Buttery is aptly named. The Madison vanilla cupcake, which shares it name with the bakery owners' dog, is topped off with a buttercream concoction that is easily the butteriest, creamiest icing this cupcake connoisseur has ever had the privilege of devouring. The icing rivals the size of the cake itself and emphasizes richness, not sweetness, which can be overpowering in treats crafted with less subtle hands. Buttery's other classic cupcake varieties, Harriet (carrot cake) and Simon (chocolate), are also pooch-inspired and equally well-made.
