McDonald’s is adding a new McFlurry to its lineup, hoping an enticing summer treat can keep customers loyal as prices keep creeping higher.

Beginning May 25 for a limited time, McDonald’s will start selling a Chocolatey Pretzel McFlurry that mixes vanilla soft serve ice cream with chocolate-covered pretzel bits, topped with a caramel swirl. It’s a “perfect combination of salty and sweet,” the company said in a statement.
