New Orleans-based Willa Jean is famous for its king cake. It’s a specialty of pastry chef and owner Kelly Fields, who took home the James Beard Foundation Award for Outstanding Pastry Chef in 2019.

The bakery’s Caramel Crunch King Cake has become quite popular with customers around Mardi Gras. It’s made with a traditional cinnamon sugar filling and topped with a crunchy caramel glaze and cream cheese frosting.

Now, popular fast food restaurant chain Shake Shack is adding that king cake to its shakes. Starting Monday, February 10 and lasting through the end of the month, Shake Shack locations in the New Orleans area will offer the King Cake Concrete – a limited-edition version of its signature blended custard dessert.
