To roll out cookies: lightly sprinkle flour on your surface, roll out dough to ⅛ inch thickness, and cut with a cookie cutter.
Place on an ungreased cookie sheet and bake for 8 to 10 minutes. Bake until the edges are set but not browned. Allow to cool completely before frosting.
Cool for 2 minutes on the cookie sheet before removing to wire cooling racks. Allow to cool completely before frosting.
To make the frosting: In a small bowl, stir 2 Tablespoons softened butter, 2 ounces cream cheese, powdered sugar, and a pinch of salt until well combined. Add the milk and stir until smooth. Adjust the thickness of your frosting by adding more powdered sugar if it's too thin or a little bit of milk if it's too thick.
Hint: If you want round cookies, roll dough into ping pong ball-sized balls and place on the baking sheet. Use the bottom of a glass to flatten the balls to ⅛ inch thick.
