Frost the top of your milkshake glasses with the Funfetti Frosting (1/2 cup) and stick the Lucky Charms® Cereal (1 cup) to it. Set aside.
Add Mint Chocolate Chip Ice Cream (2 pint), Milk (1/4 cup), Vanilla Extract (to taste), and Vanilla Vodka (3 fluid ounce) to your blender. Blend until smooth.
Pour your milkshake into the glasses, keeping a little room at the top. Top off your milkshake with Whipped Cream (to taste).
Add additional Lucky Charms marshmallows, Mini Colored Marshmallows (1 cup), and Sprinkles (3 tablespoon). Place a few mini marshmallows and your Large Marshmallows (3) on a skewer and add as a final touch.
