To make the cookie dough, start by creaming the butter. Then gradually add sugar and flour. Beat until light and fluffy.
Divide dough in half, center each portion into its own gallon-sized plastic food storage bag, and roll to ⅛-inch thickness. Chill dough anywhere from 20 minutes to several days.
Preheat oven to 350°F. Cut dough into stars with a 3-inch star shaped cutter.
Bake at 350°F for 10 minutes or until edges are slightly browned. Remove from oven and allow cookies to cool.
Blend together 2 tablespoons of Challenge Butter, 4 ounces of cream cheese and ⅓ cup powdered sugar (have ingredients at room temperature).
Spread baked cookies with cream cheese topping and arrange thin slices of strawberries and a few whole blueberries on top.
