After announcing that it was releasing the Caramel Brownie McFlurry in early April, McDonald’s (MCD) is now letting everyone try it for free.

The burger chain is offering a free regular-size version of the creamy treat on Sunday at participating McDonald’s restaurants.

To get the free Caramel Brownie McFlurry, customers must scan the offer code in the McDonald’s app and pick up the sweet menu item at a nearby location. But no purchase is necessary to take advantage of the deal, McDonald’s said.

For those customers who would rather enjoy the Caramel Brownie McFlurry at home, McDonald’s is offering a similar promotion through McDelivery with UberEats from Saturday to May 9. Anyone that makes a minimum purchase of $15 through McDelivery can get a regular-size Caramel Brownie McFlurry for free delivered right to their home with their order.

The Caramel Brownie McFlurry will make its debut at McDonald’s restaurants on Saturday. The creamy concoction features vanilla soft serve made with real dairy, brownie pieces, and caramel topping that is blended throughout.

The offer from McDonald’s is valid one time on Sunday and cannot be combined with other offers, the chain said.

McDonald’s has recently introduced a flurry of new menu items. One of its latest releases to come in May is the K-pop band BTS combo meal that will launch in the U.S. on May 26, followed by a global release shortly after.

The BTS combo meal consists of 10-piece Chicken McNuggets, medium fries, medium Coke, and Sweet Chili and Cajun dipping sauces.

McDonald’s has promised more surprises to come with its partnership with BTS as it looks to capitalize on the star power of the South Korean boy band to attract a younger generation of customers. The band has a massive following on social media, with 34.5 million fans on Twitter and 40 million followers on Instagram.

Shares of McDonald's were trading at $234.11 as of 9:39 a.m. EDT, down 87 cents or 0.37%.
