Pour the heavy whipping cream in a bowl and mix until it becomes stiff. Takes about 8 minutes. Start with the mixer on low and slowly increase the speed as it becomes like the consistency of whipped cream.
In a separate bowl, combine the instant coffee, sugar, and hot water and mix until it becomes stiff. Takes about 3 minutes. Stop when soft peaks form.
Combine the whipped coffee into the whipped cream and stir.
Serve with lady fingers and top with powdered sugar.
