To begin, place your knife blade on a hot surface such as an oven burner or a small flame and heat the knife just slightly. Peel back foil on chocolate easter bunny and carefully cut the ears off and discard.
Next, combine vodka, coffee liqueur, espresso, cinnamon and ice in a cocktail shaker. Shake vigorously for 30 seconds until the shaker feels ice cold. Strain into a measuring glass with a pouring lip, then carefully pour into the chocolate bunny. Serve with a colorful straw and any festive garnishes you have.
