The Piping Gourmets, Miami, uses its certified gluten-free and dairy-free cake batter, along with a new vegan frosting to make all-natural gluten-free Whoopie Pies. The line launched in mid September in five flavors: Chocolate-Vanilla, Chocolate-Mint, Chocolate-Raspberry, Classic Vanilla and Vanilla-Lemon. Individually wrapped 2.75-oz. pies are sold in packs of four in the freezer case. Consumers simply thaw and serve.
