1/3 Cup crème de noyaux (also called crème de almond)
1/3 Cup white crème de cacao (plus extra for rimming glasses, if desired)
2/3 Cup vanilla ice cream
Maraschino cherries, for garnish (optional)
Colored sugar or sprinkles, for rimming glasses (optional)
If rimming glasses, moisten edges of rims with liquor or simple syrup, then dip into the sugar or sprinkles. Set glasses aside.
Add both liqueurs and the ice cream to a blender and process until smooth.
Pour into two large martini glasses and serve immediately.
