The "Grey Stuff" is an iconic dessert served at Disneyland (specifically at Maurice’s Treats and Red Rose Taverne) inspired by the line "Try the grey stuff, it's delicious!" from the song Be Our Guest in Disney’s Beauty and the Beast. In reality, the treat is a delicious, whipped panna cotta or mousse-like substance with a distinct cookies-and-cream flavor profile. It is made by folding finely crushed chocolate sandwich cookies (like Oreos) into a mixture of vanilla pudding and whipped topping. The result is a light, airy, and slate-colored frosting that is typically piped into a spiral atop a scalloped sugar cookie or a red velvet cupcake. To finish the look, it is often adorned with tiny edible silver sugar pearls. In 2026, it remains one of the most photographed food items in the park, serving as a rare example of a "fictional" movie food that was successfully brought to life for guests to enjoy.
