Shamrock Shakes

I don't do beef brisket, corned beef and cabbage, etc. so on St. Patrick's Day, my only endeavor in the kitchen is Shamrock Shakes.

Here is how I make mine:

(To serve 2 adults & 2 children.)

4 scoops vanilla ice cream
1/4 c Creme de Menthe syrup
milk (more or less depending on how thick you like your shake)
green food coloring (the syrup alone doesn't get it very green)
garnish with whipped cream and mini chocolate chips
