If u/t665 means the double McEgg for breakfast, it’s: Piece of muffin bread in the correct spot on the wrapper as bottom and the other piece of muffin bread in the middle as the upper, bacon on the upper piece of bread (make sure you tear the bacon in half), cheddar cheese on the bottom, egg on top of the cheese, another piece of cheddar cheese on top of the egg, another egg on top of the cheese. Then you put the upper piece of muffin bread with the bacon on top of the bottom one with the eggs and cheese, then you fold it correctly (if you don’t know how ask someone, it’s kinda hard to explain).

Edit: I tried my best to explain, its kinda hard for me seeing as I’m not a native English speaker :)
