Drizzle chocolate syrup into the martini glasses. Place them in the freezer while you prepare the rest of the drink.
In a shaker, combine the ingredients. Use a whisk, an immersion blender, or a frother to make sure that the sauces are broken down and well distributed.
Add ice to the shaker. Shake well until you feel the coldness through the metal shaker. Pour into the prepared martini glasses.
