Create Dough: Add all of the ingredients to a large bowl and mix well.
Chill Dough: Cover the bowl and chill the dough in the fridge for at least 1 hr and up to 2 days. For the best results, chill overnight, or at least 6 hrs. *If using store-bought cake mix, 1 hr is plenty.
Preheat Oven: Once ready to bake, preheat oven to 350℉ and line baking trays with parchment paper or silicone baking mats. Add confectioner's sugar to a shallow, wide bowl.
Shape Cookies: Remove dough from the fridge. Shape about 2 tablespoons of dough in your hand into a ball, but then continue to shape it into more of a cylindrical shape so that they're a bit taller than wide.
Coat with Sugar: Roll the dough in the confectioner's sugar and then place on a lined baking tray, 2 inches apart, and with the cylindrical shape up so they're just a little bit taller than wider.
Bake: Add tray to the middle rack and bake for 12-13 minutes.
Cool: Remove from oven and let cool on the baking tray for 1-2 minutes before transferring to a cooling rack.
Enjoy!
