In an effort to challenge mediocre, overpriced fast-food cheeseburgers, Sonic today announced that it is proclaiming the Sonic Smasher the new “Smashional Cheeseburger of America” and inviting people nationwide to experience a better burger by kicking off Smasher Week, during which the first 1 million fans who order the Double Smasher through the brand’s app or website will receive an exclusive reward, allowing them to enjoy this premium cheeseburger for $1 starting April 21, 2025.
To score the $1 Double Smasher, simply open the Sonic App or website, then head to the Deals section to redeem your reward, and place your order—this offer is limited to the first 1 million customers and is only available while supplies last.
Sonic’s Double Smash Burger features two seasoned and seared Angus beef patties layered with two slices of melted American cheese, diced onions, crinkle-cut pickles, and signature Smasher sauce, all served on a soft potato bun.
The $1 Smash Burger deal is available at participating Sonic locations nationwide for a limited time, or while supplies last, from April 21 through April 27, 2025.
