King Cake Concretes Are Coming to Shake Shack for Mardi Gras

King cakes, those colorful rings of cinnamon-y brioche eaten between Twelfth Night and Fat Tuesday, are a Mardi Gras classic. Although fillings vary, they’re typically covered in glaze and showered with gold, green, and purple sprinkles, with a plastic baby figurine hidden inside to offer good luck. (It's a whole thing.) This year, New Orleans’ Willa Jean bakery and Shake Shack are putting a fresh spin on the dessert, blending it into milkshake-like form.

Enter the King Cake Concrete, a limited-edition version of Shake Shack’s signature blended custard dessert. Each includes a slice of Willa Jean’s Caramel Crunch King Cake — prepared with cinnamon sugar filling, crunchy caramel glaze, cream cheese frosting, and sprinkles — which is then mixed with vanilla custard. (The customary plastic babies won't be included, according to Willa Jean.) It's the latest collaboration between the two restaurants, who also launched a Missi-chip-pi Fudge Concrete at the newly minted Metairie Shake Shack location in December.

Those interested will find the Concrete on the menu between Monday, February 10 and Saturday, February 29, available in a single size for $4.59 or a double for $6.79. The only drawback is that sales will be limited to two New Orleans-area Shake Shacks, Canal Place and Metairie. But if you're already planning on heading down to NOLA to celebrate, it might be a worthy pitstop.

If you’re not in the New Orleans area, you can still order Willa Jean’s baked goods straight to your door thanks to a recent partnership with Goldbelly. In July 2019, the bakery joined the online food marketplace to offer its famous chocolate chip cookies—made with three types of Valrhona chocolate and sprinkled with sea salt—as well as cornbread, peanut butter chocolate chip cookies, banana bread, oatmeal dried fruit cookies, chocolate espresso cookies, and two different combo options to customers all around the country. Each order, save for the cornbread and banana bread combo, costs $59; delivery is free to all 50 states.
