KANSAS CITY — Sweet treats are trending on restaurant menus, and a number of chains are joining forces with confectionery makers to craft new mashups.

Dairy Queen has partnered with The Hershey Co. to launch two new Blizzard Treats inspired by limited-edition Reese’s Peanut Butter Lovers and Reese’s Chocolate Lovers Cups.

The Reese’s Peanut Butter Lovers Blizzard Treat contains bits of Reese’s peanut butter cups blended with creamy peanut butter and vanilla soft serve, while the Reese’s Chocolate Lovers Blizzard Treat includes chunks of Reese’s peanut butter cups, cocoa fudge and vanilla soft serve.

“The limited-edition Reese’s Lovers Cups are flying off store shelves, making DQ restaurants a go-to destination to get a special Reese’s Lovers experience,” said Maria Hokanson, executive vice-president of marketing for American Dairy Queen. “Whether you’re a chocolate fan or more of a peanut butter fan, the only question left to answer is, which Blizzard Treat will you try first?”

Also introducing a Reese’s-themed treat is Cold Stone Creamery. The new Reese’s Peanut Butter Ice Cream Cup features a chocolate cup filled with layers of Reese’s peanut butter sauce and chocolate ice cream topped with fudge ganache, sea salt and a Reese’s peanut butter cup.

“We’re pleased as peanut butter to partner with Reese’s on this new product line,” said Sara Schmillen, vice-president of marketing at Cold Stone’s parent company Kahala Brands. “Peanut butter and chocolate have always been a dreamy flavor combination; add in ice cream and sea salt and it’s more decadent than ever. The new Reese’s Peanut Butter Ice Cream Cups are made fresh in every store and hand-crafted in small batches to ensure the best quality and taste in every cup.”

At Steak ‘N Shake, a new milkshake is inspired by the recently released Reese’s Outrageous Bar. The new Reese’s Outrageous Milkshake features a blend of vanilla ice cream, Reese’s peanut butter sauce and chocolate syrup topped with hot caramel sauce, Reese’s Pieces candies, whipped cream and a maraschino cherry.

Burger King and Mars, Inc. collaborated to craft the new Vanilla Shake Made with Twix Pieces. The treat contains a blend of vanilla soft serve, Twix candy bar pieces and vanilla syrup all topped with a sweet whipped topping.
