Levain Bakery has announced a brand-new seasonal cookie just in time for summer. Starting Tuesday, June 21, Rocky Road will be available in all Levain bakeries and online through the end of summer.

Rocky Road features dark chocolate cookie dough mixed with rich semisweet chocolate chips, marshmallows and roasted cashews. The flavor will also be available in a new summer cookie assortment in 4, 8 and 12 packs that also feature Oatmeal Raisin, Dark Chocolate Chocolate Chip, and Chocolate Chip Walnut cookies.

“We only make cookies we truly love,” says founders Pam Weekes and Connie McDonald. “It is fitting that our first seasonal cookie features chocolate and marshmallow, a classic combination we’ve loved since we were kids. As for the cashews, in our opinion, they simply don’t get as much attention as they deserve! But with a rich depth of flavor, they balance the sweetness of the chocolate and marshmallows.”

In addition to the current ten bakeries in New York, Washington, DC and Boston, Levain Bakery is expanding beyond the east coast to Chicago and Los Angeles this year.
