Add instant coffee and sugar to a large bowl. Add hot water and stir to combine. Use a hand mixer or whisk to vigorously mix coffee mixture until mixture turns fluffy, shiny, and foamy. It should take about 2 to 3 minutes using a hand mixer, or 7 to 8 minutes using a whisk.
Add ice to a large jar along with whiskey, Irish cream liqueur and hemp milk. Stir well to combine. Strain mixture into 2 glasses, filling each about 3/4 full. Top with whipped coffee mixture and shaved chocolate, to garnish. Enjoy immediately!
