Boater Cookies

at some point my sister gave me a whoppie pie pan.
i have never made whoopie pies.
but i do, occasionally, use the pan for baking normal cookies.
the result, (if you over-stuff each little "compartment") is a sort of muffin top cookie.
they are rounder, more even, and thicker, and have a crisp little ledge around the edge.
the kind of look like little boater hats.
