The baker — and artist — created the icing-topped cake last year and shared it on her bakery's Facebook page during Sunday's blizzard.
The cupcake features two upturned trash cans, one green and the other tin, suspending a broom with a note reading, "DIBS!" The objects are all made from pliable sugar paste and food coloring, she said.
But McAtee, who hasn't participated in the practice of dibs herself, said she wasn't taking sides in the debate.
"I’m dibs-neutral," she said Wednesday of the longtime Chicago tradition of reserving shoveled parking spaces with household objects. "It’s one of my favorite urban cupcakes that I’ve done."
And she said she was willing to remake the novelty cake for anyone who wanted one.
While she doesn't have a set price for her special-order cupcakes, her website advertises in-store cupcakes for $3.50 each, and lists custom cupcakes starting at $4 apiece, with a minimum order of one dozen.
McAtee opened Maddiebird at 1445½ W. Devon Ave. last year.
