KANSAS CITY — Dill pickle, cake batter and cereal milk are among trending flavors inspiring recent restaurant menu innovation.

Sonic Drive-In is introducing the Big Dill Cheeseburger, with crispy pickle fries, crinkle-cut pickle slices and a creamy dill-infused ranch sauce, plus a beef patty, lettuce and American cheese on a toasted brioche bun. The restaurant chain also is serving pickle fries, which are dill pickle spears that are fried and served with a side of ranch sauce for dipping.

“Our Sonic guests know that they’ll be able to find something new, unexpected, and totally craveable every time they visit their local drive-in,” said Mackenzie Gibson, vice president of culinary and menu innovation at Sonic. “As we roll into summer, we wanted to make pickles the star of the show with these two new items that provide the ultimate pickle experience.”

Dunkin’ is debuting a slate of new menu items ahead of the summer season, including the Cake Batter Signature Latte, topped with whipped cream, a mocha drizzle and rainbow sprinkles.

Krispy Kreme, Inc. is partnering with General Mills, Inc. cereal brand Cinnamon Toast Crunch to launch three donut flavors in a new Cinnamon Milk Glazed product line. The new items include a cinnamon milk glazed donut, a cinnamon milk glazed donut topped with cream cheese icing and cereal pieces, and a cinnamon milk glazed donut topped with dulce de leche and cereal pieces. The cream cheese and dulce de leche flavors also feature a sprinkling of cinnamon sugar on top.
