Preheat oven to 375 degrees Fahrenheit. Gather 2 cookie baking sheets and set aside.
In the bowl of a stand mixer, add all ingredients and mix (first on low power, proceeding gradually to medium power) for several minutes. The dough with go through several stages: first dry, then crumbly, eventually coming together in a ball, cleaning the sides of the bowl. Remove from stand mixer.
Using a medium cookie scoop, portion out dough and flatten between the palms of your hands. You should be able to fit 12 of them per cookie sheet.
Bake for 13-15 minutes, then remove from oven and let sit on baking sheet for 2 minutes before transferring to wire racks to cool completely.
Sprinkle with powdered sugar before serving, if so desired. (I chose not to.)
