Unwrap Milk Snack bars and apply frosting to the side on one, then place a second along side. Press together gently to "attach" them to each other.
Using a football shaped cookie cutter, press down on milk snacks to create the football shaped treat. If your cookie cutter is larger than the two bars, add another bar or two to fit. Repeat for all bars.
After cutting, add icing using a decorator's bag with a small, narrow decorator's tip. Draw a long center line down the football, then add smaller perpendicular lines to create the laces.
Chill to set for about an hour, then serve when ready. Refrigerate any leftovers.
