Place melted butter in a large mixing bowl and add each remaining ingredient as listed, beating well after each addition to achieve a smooth dough. Let dough stand uncovered 10 minutes.
Make golf-ball-sized shapes of the dough and insert a flat, wooden popsicle stick (purchased wherever craft supplies are sold) into one side of each ball. Carefully flatten each ball of dough to a 1/2 inch thick patty.
Place 3 inches apart on greased baking sheets. Bake at 400°F for 6-8 minutes or til just browned around the edges, but still white on tops of cookies.
Remove from the oven and smear the top of each cookie generously with heated, canned, ready-to-spread frosting (flavor of your choice). Frostings may be tinted with few drops food coloring once it has been heated. Let cookies cool on baking sheet 10 minutes before carefully removing to paper towels.
