McDonald’s offers two iconic burgers worldwide: the Big Mac and the Double Quarter Pounder, each with distinct characteristics. The Big Mac features smaller, flash-frozen patties and a special sauce, totaling 580 calories, while the Double Quarter Pounder boasts larger, fresh patties, two slices of cheese, and a higher calorie count of 740, but lacks the Big Mac’s middle bun and sauce. For a unique twist, the Denali Mac combines elements of both, available primarily in Alaska but customizable at other locations.
