Start by cutting marshmallows in half with a scissors set them gooey side up on a plate.
Unwrap and break apart chocolate.
So you whip up some peanut butter cookies and scoop them onto cookies sheets.
Set your timer for a minute or two less than the recipe calls for. Bake.
Pull one sheet of cookies out when the timer goes and top each cookie with half of a marshmallow. Put the tray back in the oven for another minute or two until lightly browned on the top. Get them out and top with chocolate.
They need to cool. I often stick the tray in the fridge after a few minutes to get the chocolate good and hard again.
They are kind of amazing.
