Make the whipped cream first by combining 1 teaspoon of the sugar and the heavy cream
Use a handheld mixer, whisk, or milk frother to whip the cream, and set aside.
Combine the espresso, vodka, chocolate liqueur, and sugar or simple syrup in a cocktail shaker with ice
Shake vigorously for at least 30 seconds
Divide the mixture between 2 martini glasses (pouring through a strainer to keep the ice out of the glass)
Add a dollop of your homemade whipped cream and some chocolate shavings to garnish
Notes
You can take this drink to the next level by dipping your martini glass into melted dark chocolate and then sprinkling with a little cocoa powder before adding the beverage.
