Zingerman’s BAKE!, the six-year-old hands-on teaching bakery located next to Zingerman’s Bakehouse in Pittsfield Township, recently doubled its class offerings in an expansion.

Bakehouse owners Frank Carollo and Amy Emberling converted space in their building — which is located in the Airport Plaza business park in Pittsfield Township — into a second teaching kitchen to offer more classes.

BAKE!’s more than 50 different classes range from “Bakin’ with Bacon” to “Pie Fillings” and “American Cookies,” and they are offered six days a week. The classes have a 12-person maximum.

To staff the new kitchen and keep up with increasing class demand, the company also hired three additional employees, according to a news release.

Zingerman’s is also looking to convert a vacant 6,400-square-foot space in the same industrial park into a permanent training facility for its ZingTrain division, which provides consulting and teaching on Zingerman’s business techniques to clients. The company signed a lease for the space earlier this year.

Five Zingerman’s divisions are located in the business park: the Bakehouse and Bakeshop, Creamery, Coffee Company, Candy Manufactory and Zingerman’s Service Network.
