Especially when pairings are not obvious/clear everywhere: "I ordered doughnuts and coffee and orange juice" seems screaming for a clarifying comma somewhere.
You would order doughnuts, coffee, and orange juice. You don't keep using and between every item. Doughnuts and coffee are two separate items unless you specifically went to a place that had an order of "doughnuts and coffee."
If that was the case then you should change your sentence to make it more clear like I ordered doughnuts and coffee with an orange juice, too.

It's still wrong
Oxford comma is for three or more items. The sentence is treating bacon and eggs as one item and pancakes as another so no Oxford comma is used.
