5Preheat oven to 375. Spray 9x13 pan (glass works better) and place slices evenly in pan. cover with sprayed plastic wrap and let rise in a warm place for about an hour (or until they double). Bake at 375 for about an hour.
6FROSTING: Melt butter and soften cream cheese in microwave safe bowl, stirring often until well mixed and creamy. Add remaining ingredients, adding powdered sugar to taste. Spread on rolls while still warm.
