The Mc10:35 is a secret menu item sold by McDonald's. As its name suggests, it can only be ordered during a certain time window, specifically from 10:30 a.m. to 11:00 a.m. The burger consists of an Egg McMuffin with extra McDouble patties.
How to orderEdit
Wait until at least 10:30 a.m. Ask for a McDouble and an Egg McMuffin. Put the McDouble patties within the Egg McMuffin and there you go.
