As long as you are going to be wearing green this Saint Patrick's Day, why not drink something green, too? Children will appreciate the opportunity to join in the festivities with this sweet and sparkly beverage. Since it's made with milk, the punch is good for them, too.
Combine milk, ice cream or frozen yogurt, extract, ice cubes, and food coloring in a blender.
Mix until smooth. Pour into glass. Add a splash of seltzer water and top with a dollop of whipped cream.
