Homemade Overnight Cinnamon Rolls
Add the confectioners' sugar, cream/milk, and vanilla. Beat on low speed for 30 seconds, then switch to high speed and beat for 1 minute. Spread the icing over the warm rolls and serve immediately. Cover leftover frosted or unfrosted rolls tightly and store at room temperature for up to 2 days or in the refrigerator for up to 5 days.
