Surprise young revelers with a tower of doughnuts after dinner. Replace the centerpiece at kids' tables with this enticing display. We used chocolate, strawberry, and vanilla frostings, and mixed milk to match. If your local doughnut shop doesn't carry flavors you fancy, ask if they'll mix custom icings for you. Be sure to place flattened paper cupcake liners in between doughnuts so they won't stick together.
