Starting Monday, the fast food chain Culver’s, originating from Wisconsin, is introducing three new concrete mixers that incorporate classic breakfast cereals.

The limited-time lineup — a collaboration with General Mills — includes Lucky Charms, Cocoa Puffs, and Cinnamon Toast Crunch.

“Cocoa Puffs offer a chocolaty crunch, Cinnamon Toast Crunch provides a bold burst of flavor, and Lucky Charms marshmallows add a touch of sweetness to each spoonful,” explained Kasey McDonald, Culver’s head of culinary, in a statement. “By blending these with our frozen custard, we evoke a sense of nostalgia, reminiscent of watching Saturday morning cartoons from childhood.”

If you’re eager to sample all three varieties, participating locations now feature cereal concrete mixer flights, enabling you to enjoy three mini concrete mixers while only paying for two.

Moreover, Culver’s has included these cereals as mix-ins for a customizable concrete mixer. This allows you to blend them with over two dozen other toppings available on the menu.

The cereal add-ins themselves, however, will only be available “while supplies last,” Culver’s said.
