Everyone loves the Whoopie Pies at One Girl Cookies, so I was surprised to see a Whoopie making class offered at the shop on a warm September evening. The secret it turns out, is all about the piping. Once you master the pastry bag you can make as many Whoopie Pies as your heart desires. Francina, the cake master, demonstrated the two flavors of batter, pumpkin and chocolate, as well as the sweet cream cheese and mocha fillings. There was plenty of time to work on your piping technique and in the end take home a nice batch of fresh made goodies. Whoppie!!! I’ve shared how it’s done but you’ll need the One Girl Cookies Cookbook for the not so secret recipe.
