Home Bake’t Muffin?

Richard writes:

This sign was in the window of a small cafe near Fisherman’s Wharf in San Francisco. There was a sign on the sidewalk which read “Home of the World’s Famous Breakfast,” and the home bake’t muffin was part of it.

The breakfast was lousy.

I wonder if the apostrophe is signaling the omission of “r stree”, linking this muffin to Gerry Rafferty’s Baker Street? Wait, that makes no sense.
