01 - In a chilled bowl, whip the heavy cream with powdered sugar using a hand mixer or whisk until soft peaks form. Refrigerate until ready to use.
02 - Combine vanilla ice cream, milk, peppermint extract, and green food coloring in a blender. Blend on high speed until completely smooth and creamy, approximately 30-45 seconds.
03 - Add mini chocolate chips to the blender and pulse 2-3 times to distribute evenly while maintaining small chunky pieces throughout the mixture.
04 - Pour the milkshake evenly into two tall glasses, leaving about 1 inch of space at the top for toppings.
05 - Top each glass with a generous dollop of the prepared whipped cream, creating a peaked mound on the surface.
06 - Sprinkle additional chocolate chips or chocolate shavings over the whipped cream and garnish with fresh mint leaves if desired. Serve immediately with straws while cold.
