Instructions

1. Scoop vanilla ice cream into a blender. Use about 2 cups of ice cream for every two shamrock shakes you plan to make.

2. Pour in low-fat milk. Add about 1 /12 cups of milk for every 2 cups of ice cream.

3. Add mint extract and green food coloring to the milk and ice cream in the blender. Add approximately 1/4 teaspoon of extract and about 8 drops of food coloring for every 2 cups of ice cream.

4. Fit the blender's lid securely into place. Turn on to high speed. Blend the shake ingredients until smooth, stopping and stirring the mixture occasionally with a spoon, if needed.

5. Serve the shamrock shakes with straws in tall glasses, each topped with whipped cream and a maraschino cherry, if desired.
