The cookie features crunchy buttery toffee bits and brown sugar and is available now, while supplies last. It joins a cookie selection that also includes Oatmeal Chocolate Chip, Chocolate Brownie, and Sugar Cookies.
Potbelly bakes its cookies at each location daily.
"Butter Brickle" appears to refer to one of two things: chocolate-covered toffee (like Heath candy bars) and toffee pieces for adding to ice cream (there are quite a few butter brickle ice creams out there). Since there's no chocolate involved here, Potbelly's name for the cookie seems to reference the latter usage.
