Beat three 8-ounce packages cream cheese and 1 stick butter (both at room temperature) with a mixer until creamy. Beat in 1 cup confectioners’ sugar, 2 teaspoons vanilla and 1/2 teaspoon salt. Divide into 3 balls (large, medium and small) and wrap each in plastic wrap. Chill 2 hours, then roll in unsweetened shredded coconut and stack the snowman. Add brown mini M&M’S for the eyes, mouth and buttons, and red and green M&M’S for the nose and scarf (attach with icing, if necessary). Add pretzel arms. Serve with fruit or cookies.
