Warm cookie delivery bakery Tiff’s Treats has added a new cookie flavor to its permanent menu: Double Chocolate Chip. The first new flavor on the permanent menu in five years, the chocolate cookie with semi-sweet chocolate chips is available at any Tiff’s Treats location.

“We want to continuously be innovative with our menu and add new items we know our customers will love,” says Tiffany Chen, co-founder of Tiff’s Treats. “We created our Double Chocolate Chip cookie based on the success of other chocolate-based cookies we’ve offered as flavors of the week, and we think it will become a customer favorite right away!”

Among the Tiff’s Treats menu are ten other classic cookie flavors, three brownies, the Tiffwich ice cream sandwich and the Tiffblitz frozen dessert, which features cold vanilla ice cream blended with chunks of chocolate chip cookies and fudgy brownie bites, then topped with crumbled sugar cookies.

Tiff’s Treats founders Tiffany and Leon Chen recently signed a book publishing deal with Harper Horizon to tell the story of how they took Tiff’s Treats from $20 and a college apartment kitchen to a rapidly growing brand with millions of customers and $85 million in funding. The book will be available in 2022 and will include homemade versions of some of their favorite cookie recipes.
