Dip your martini glass rim into the frosting and slightly twist covering the rim with the frosting.

Roll the rim into the sprinkles and set aside.

In a cocktail shaker filled with ice, combine the vodka, white chocolate liqueur and half and half.

If you want to have a colorful pastel drink, add 2-4 drops of food coloring of your choice.

Shake and strain your Birthday Cake Martini into your prepared martini glass.
