Using the cookie scoop of your choosing (baking times may vary) scoop balls of dough onto a baking sheet, leaving approximately 2-in space between them. Flatten each dough ball slightly. Bake until set and cookies are slightly golden, approximately 12 to 15 minutes.
Cool cookies and transfer to a wire rack to cool completely. Store cookies in an airtight container.
