The burger is twice the glory of the fast food classic sandwich, at least in terms of meat. There are four patties and more Big Mac sauce, but not double the American cheese—there’s only one slice. All that heft is sandwiched between two sesame seed buns.

News of the Double Big Mac’s return comes on the heels of the chain’s tweaks to four of its classic burgers. Starting this year, the restaurant says its hamburger, cheeseburger, double cheeseburger, McDouble burger and Big Macs will all have meltier cheese and fresher tomatoes and lettuce.

The fast food chain will also add onions to burger patties while the meat is on the grill and grill six patties at a time instead of eight.
