The Big Game is in the Big Easy and Cardi B is teaming up with a famous booze brand to make history … in the form of a 350-gallon daiquiri the world has never seen.

Fat Tuesday and Cardi B’s Whipshots are getting the party started in New Orleans for Super Bowl LIX with the world’s biggest daiquiri … a monstrosity of a cocktail that was six months in the making.

A marvel of engineering, the 350-gallon cocktail lives within a 22-foot tall container made from solid steel. The drink features a Fat Tuesday frozen mix and it’s topped off with Whipshots, Cardi’s vodka-infused whipped cream.

Jeff Beacher — the showman behind the famed Beacher’s Madhouse — is the guy pulling all the strings here … we’re told he invested over $250,000 to pull this off, with six months of engineering needed to bring this idea to life.

The massive drink was poured Friday morning at Fat Tuesday on Bourbon Street … but it’s too big for revelers to consume. Instead, it’s serving as a prop for photo ops.

Fat Tuesday will be serving smaller versions of the world’s largest daiquiri all night at its pre-Super Bowl party … 18-oz yards filled with strawberry margarita made from Don Julio 1942 tequila.

The drinks are called the Royal Rita, in honor of Cardi.
