Melt Dark Chocolate (100 gram) in a bowl big enough to dip your martini glasses.
Gently dip the martini glasses so that the rim is covered in chocolate. Once coated, leave the glasses in the freezer for about 5 minutes to chill.
In the blender, add Vanilla Ice Cream (2 cup), Milk (1 1/2 cup), Bailey's® Irish Cream (1/2 cup), Kahlua (1/2 cup), and the leftover dark chocolate. Blend until combined.
Pour the mixture in prepared glasses and garnish with Chocolate (to taste).
Serve immediately and enjoy!
