The Little Mac is similar to a McDonald’s single cheeseburger: It’s a single patty with a dollop of Special Sauce. It costs $2.29.
The Double Big Mac, which costs $5.49, has four burger patties. It has 720 calories and 43 grams of fat.
By comparison, a regular-sized Big Mac, which has two patties, costs $3.99. It has 540 calories and 30 grams of fat.
McDonald’s has sold different versions of the Big Mac in the past. In 2017 and 2018, it sold the Grand Mac and the Mac Jr. The Grand Mac used only two patties, but they were larger than a typical piece of meat used on a regular Big Mac. It also had a larger bun.
This promotion could help McDonald’s restaurants create buzzy “new” menu items without the burden of ordering new ingredients or training staff on how to make them.
