1Heat oven to 350°F. Spray cookie sheet with cooking spray. Remove dough from wrapper; press or roll on cookie sheet into rectangle shape. Bake 10 to 12 minutes or until lightly browned. Immediately cut with 2- to 2 1/2-inch foot- or slipper-shaped cookie cutter (or cut freehand with knife); cool. Gently remove cookies from cookie sheet.
2In small bowl, mix cheese and powdered sugar to form dough-like paste (if too thick, add a little milk, and if too thin, add more powdered sugar). Shape tablespoonfuls of dough into rounded mounds for top of slipper. Place 1 mound on each cookie.
3Set aside 1/2 cup of the chopped white chocolate. Place cooling rack on sheet of waxed paper.
4In microwavable bowl, microwave remaining white chocolate and the coconut oil uncovered on High in 30-second increments, stirring until smooth. Gently dip top of each slipper cookie into melted white chocolate, letting excess drip off. Sprinkle mounded portion of slipper with reserved chopped white chocolate. Place on rack; let stand until set.
