"Founded by pastry chef Christina Tosi after her tenure running David Chang’s pastry program, this bakery built a cult following with childhood‑inspired innovations like cereal‑milk soft serve, a birthday‑cake flavor, 'naked' layer cakes, and standout items such as the Compost Cookie—a dense, mix‑in cookie studded with butterscotch, chocolate, pretzel bits and potato chips. With 16 locations and a high‑profile media presence through cookbooks, TV appearances and judging on MasterChef, the brand’s techniques (from sprinkling brownies with sea salt to adding pretzels to cookies) have been widely adopted across bakeries and packaged goods. Recently it secured Series B funding from Sonoma Brands (the company behind Dang and Krave) to expand into national grocery distribution—building on past retail moves like a cookie mix at Target and a SoulFuel cookie at SoulCycle—with plans to place the Compost Cookie and a renamed signature pie in supermarkets such as Publix. Leadership describes this as a 'conscious evolution,' but the central challenge remains whether mass‑market versions will match bakery quality and preserve what made the products special." - Jaya Saxena
