So this is a fun idea I found somewhere - probably Family Fun (I can't remember) - and we used this for a "Hats Off" church event. You could make these cookies for a springtime party, though, or any occasion you want.
So you use those fudge stripe cookies, peanut butter cups, and colored frosting. KIDS can do this! Put a big blob of frosting on the peanut butter cup, press it down onto the cookie and let it smoosh out the sides. (smoosh is TOTALLY a word) That's your "ribbon" for the brim of the hat. Then pipe on a bow with frosting using a round cake decorating tip, and top it off with a flower blob-thing with the "star" decorating tip. Flower blobs aren't hard to do and if you were to play with the frosting on some waxed paper for a minute, you'd figure out how you want your flower to look.
You don't have to be a pro - just do enough to get by in order for your cookies to look edible! And, seriously, folks - how can you mess up a fudge cookie, peanut butter cups and FROSTING?! You just can't go wrong here.
