Sugar Cookie Cupcakes

1 large Sugar Cookie Dough package
2 1/2 sticks (10 ounces) unsalted butter, at room temperature
5 cups confectioners' sugar
1 tablespoon pure vanilla extract
1 to 2 tablespoons milk

Roll the cookie dough into small balls and mold into mini muffin tray cups. Bake until golden and let cool.

In the meantime... In a large bowl, using a mixer, beat the butter on medium speed until creamy, about 1 minute. Add the confectioners' sugar, 1 cup at a time, beating until smooth after each addition. Add the vanilla and 1 tablespoon milk. Beat at high speed until fluffy, adding an additional 1 tablespoon milk if necessary. Decorate with frosting and sprinkles.
