This is a McDonald's knockoff that you can make at home - and you can make it dairy-free!
(Adapted from What's That Smell?)
2 cups VANILLA ICE CREAM
1 1/4 cups MILK or dairy alternative
1/4 teaspoon MINT EXTRACT
8 drops GREEN FOOD COLORING (if desired)
1. Mix all ingredients in a blender until smooth.
Note: For extra decadence, add chocolate syrup for a mint chocolate shake!
Makes about 2 shakes or one really big one!
