Shape the Cookies: Roll the dough into balls and place them on a baking sheet lined with parchment paper. You can also flatten them slightly.
Bake: Bake in a preheated oven at 375°F (190°C) for 8-10 minutes, or until the edges are lightly golden brown.
Cool and Decorate (Optional): Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Decorate with melted white chocolate, sprinkles, or any other toppings you like.
