Cream 1 cup (2 sticks) of unsalted butter or margarine with 1 tablespoon of vanilla extract. Gradually stir in the Snowball Cookie Mix until ingredients are well combined. Dust your hands with a little of the confectioners' sugar and roll the dough into 1-inch balls. Place 2 inches apart on baking sheets and bake, in a preheated oven, for 5 minutes at 325 degrees F or just until light brown. Transfer to racks to cool for 15 minutes, then roll in the confectioners' sugar.
These cookies keep well in an airtight container for up to 2 weeks. Do not freeze them.
Makes about 4 dozen cookies.
