MELT NESTLÉ® TOLL HOUSE Dark Chocolate Morsels in 30 second intervals in microwave. Dip half of each churro in chocolate and let cool completely.
ADD a scoop of your ice cream of choice, and use another cooled dipped churro to sandwich the scoop. (Cool trick: if using Dreyer’s 5.8 oz. or 14 oz. containers of ice cream, you can just cut the actual cup into slices and put in between your churros.) Roll the ice cream middle on a plate of rainbow sprinkles, covering your ice cream center. Serve immediately or freeze for later.
