Breadcrumbs are made by using a knife on a loaf of bread.
They are an ingredient used during the Pirate Pete part of the Recipe for Disaster quest to make a raw fishcake which players learn how to make completing the mini-quest.
Breadcrumbs are also used as payment to a bellshroom plant in order to enter and exit a secluded area in the Tar Swamp on Fossil Island.
