"Corked" Breton Galettes

Breton galettes, from Dories Cookies, are thick, round buttery cookies.  The dough is shaped into a roll, chilled, sliced, and baked in a muffin tin. The recipe instructs us to press a cork or the end of a wooden spoon into the cookies when they come out of the oven.  I added jam to the holes, and can see it will be fun to experiment with other fillings.
