I used the recipe from Two Peas and Their Pod. Since it was my first time making this type of cookie, I followed the recipe almost exactly as they wrote it. The only ingredient that I adjusted was the vanilla in the frosting, which I doubled (just because I love vanilla!) . I also chilled the cookie dough a little differently because of how my dough turned out. It was too soft and sticky to form disks right away, so I chilled the dough in the bowl for about two hours before making disks to cool for longer. I will also warn you that this recipe makes a ton of dough (and cookies). My mixer had trouble handling all of the batter, so I'd recommend incorporating the last of the dry ingredients by hand (with a spoon, not your actual hands...too sticky and messy!). I loved this recipe and will use it again!
