Prepare the Glass:

Drizzle chocolate syrup around the inside of a martini glass.

Place the glass in the freezer to chill while you prepare the drink.

Mix the Drink:

In a shaker, combine the vodka, coffee liqueur, espresso, and chocolate syrup.

Fill the shaker with ice, ensuring there's enough to chill the liquid thoroughly.

Shake:

Secure the lid on the shaker and shake vigorously for about 15 seconds. The goal is to chill the mixture quickly while slightly diluting it with the melted ice, improving the drink's texture.

Serve:

Strain the mixture into your chilled martini glass. The drink should have a nice froth on top from the shaking.

Garnish:

If you like, float three coffee beans on the froth for a classic espresso martini garnish. A swirl of chocolate syrup can also add an extra touch of elegance.
