Mary Ann Pan, Mary Ann Cups
A Mary Ann Pan is a cake pan with a convex bottom. After the cake is baked and turned out, you have a cake with a hollowed out top which may then be filled with fruit, cream, ice cream, etc. Also called Mary Ann Tin.
 
Mary Ann Cups are a set of nested measuring cups.
 
I do not know who Mary Ann was, or if they are both named for the same person. I welcome any stories about either of these Mary Anns

Mary Ann’s Cake Shell Pan
Something You Have Been Waiting For
A new cake.
A new way to bake it.
A doen new ways to serve it.
Mary Ann Cake Shell Pan revises all the ways of making a cake—even bakes the bottom of the cake outside the pan—bakes a shell as dainty and tender as a fresh honeycomb—bakes it with depth enough to take in a big satisfying filling of custard, berries, fruit, jelly, preserves, anything very good to eat. Topped offf with whipped cream or marshmallow, how could dessert be more enticing or appetizing? One piece of highly polished aluminum—not a seem or rough spot, washes clean like a china cup; wear forever. See it in our Housekeeping Department.
