I have not made these into the icicle shapes but I have made this recipe into less time consuming shapes and still used the glaze and glitter (you can order the glitter online from King Arthur Flour). Very yummy and pretty no matter what shape you choose. I put 24 cookies but that depends on how big you make them and I can't say how long it will take to make the icicles as I've not done that, so don't go by that it says below. I just had to put something in. Prep time includes 4 hrs of chill time.
