Add the vodka, amaretto, espresso, and simple syrup.
Shake hard for 20 to 30 seconds until very cold and frothy.
Strain quickly into the chilled coupe glass.
Garnish with three coffee beans.
Notes
Espresso: Use a freshly pulled shot, hot with crema. The crema is what creates the frothy top. Cold brew or instant won't give you the same result.
Simple syrup swap: You can replace the simple syrup with homemade non-alcoholic coffee liqueur for more coffee depth, or a coffee liqueur if you want to go full classic.
