Start by gathering your shot glasses and a butter knife. Use the knife to spread a thin and even layer of white icing around the top rim of each glass.

Carefully dip the frosted rims of the glasses into a bowl filled with colorful Christmas sprinkles, ensuring even coverage without twisting the glasses.

In a cocktail shaker, combine 1 ounce each of Baileys Irish Cream, vanilla vodka, half-and-half, and amaretto. Fill with ice and shake gently for about 15 seconds.

Strain the creamy mixture evenly into each glass, filling just to the brim, showcasing the festive rim you've created.

Arrange the shot glasses on a frosted tray and consider garnishing with a small cinnamon stick or candy cane for visual appeal.
