Isabelle's Curly Cakes

Isabelle's Curly Cakes in Boston, Massachusetts serves up oversized cupcakes, sure to satisfy even the sweetest sweet tooth without weighing you down. Their signature Italian buttercream frosting starts with a meringue, adding in soft butter for a light, mousse-like finish. Try it on the Chocolate and Peanut Butter Cup, a decadent chocolate cake filled with Reese's peanut butter ganache, topped with a chocolate peanut butter buttercream, and finished with chopped Reese's candies. — Marilyn He, 11/8/2012
