Prepare the Frosting Rim

1. Use a butter knife or offset spatula to spread vanilla frosting around the rim of a martini glass. For a quicker method, dip the rim directly into a small bowl of frosting.

Add the Festive Sprinkle Rim

1. Pour colorful sprinkles onto a small plate or shallow dish. Gently dip the frosting-coated rim of the glass into the sprinkles, ensuring they stick evenly. Set the decorated glass aside.

Mix the Cocktail

1. In a cocktail shaker, combine vanilla vodka, Bailey’s Irish Cream, whole milk, amaretto, powdered sugar, and ice. Secure the lid tightly.

Shake it Up

1. Vigorously shake the cocktail shaker for at least 15 seconds. This step chills and blends the ingredients while creating a smooth, creamy texture.

Pour and Serve

1. Strain the cocktail into the prepared glass, taking care not to disturb the sprinkle rim. Serve immediately and enjoy your festive creation!
