Preheat the oven to 350F and line a baking sheet with parchment to prevent sticking (optional)
Add all the ingredients from the base recipe to one mixing bowl. Stir in your preferred additions (see below) and mix until combined
Roll the dough into balls using your hands, to form 15-18 cookies. Place each on the prepared baking sheet with some space inbetween each
Bake for 10-12 minutes. Let cool 5 minutes, then roll the cookies in powdered sugar or cacao then place them on a cooling rack to cool completely (they will become more firm as they cool)
Store at room temperature or refrigerated for up to 5 days, or in the freezer for up to 3 months
