(KTVX) – It was once just an April Fool’s Joke. Now, it is becoming a reality for just one day.

Meet the CurderBurger, described as “one big Wisconsin Cheese Curd under a lightly buttered, toasted bun.” It was also the 2021 April Fook’s Joke for Wisconsin fast-food chain Culver’s.

On October 15, National Cheese Curd Day, Culver’s restaurants nationwide will serve up a real CurderBurger.

And if you are one of the few who get to enjoy the “VERY limited” CurderBurger, Culver’s wants you to enter their sweepstakes.

If you purchase a CurderBurger on Oct. 15 or while supplies last through Oct. 22, and upload your receipt at Culvers.com/Curderburger, you have a chance to be one of 200 winners selected to receive a limited-edition T-shirt.

The CurderBurger is a ButterBurger topped with a “crown of golden fried cheese,” according to Culver’s.
