The SONIC Quarter Pound Double Stack Cheeseburger is full of flavor and bursting with melty shredded cheddar cheese and a warm cheddar cheese sauce layered between two 100-percent pure beef patties. The cheesy, savory combination is served on a soft, lightly toasted brioche bun and topped with mustard, creamy mayo, crisp crinkle-cut dill pickles and grilled onions.

"Sometimes a little something extra goes a long way, especially when it comes to a flavor profile that is extra savory, juicy, and melty," said Scott Uehlein, vice president of product innovation and development for SONIC. "We took a classic cheeseburger and elevated what makes it great – adding double the cheese in the middle, a second juicy patty and amped-up burger toppings – to create a new SONIC experience that is truly irresistible."

Starting at just $2.99, guests can order the new SONIC Quarter Pound Double Stack Cheeseburger with medium Tots while supplies last^*.
