01 - Combine vanilla ice cream, whole milk, peppermint extract, and green food coloring in a blender. Blend on high speed until completely smooth and creamy, approximately 30-45 seconds.
02 - Add chopped semisweet chocolate chips to the blender. Pulse 2-3 times for 1-2 seconds each to distribute the chips evenly throughout the mixture while maintaining visible chunks.
03 - Pour the finished milkshake evenly into two tall glasses, leaving approximately 1 inch of space at the top for toppings.
04 - Generously mound whipped cream on top of each milkshake, creating a swirling peak.
05 - Sprinkle chocolate chips or chocolate shavings over the whipped cream. Add fresh mint leaves as a finishing touch. Serve immediately with tall spoons.
