Firstly, mix the coffee powder and sugar in the water. Next, separate the bourbon, dip each slice in the black coffee mixture and line a glass bowl with these bourbons.
Now take the fresh cream in a bowl and fold in the powdered sugar. See that the cream is thick and not watery.
Subsequently, pour the cream over the layer of bourbons. Place the bowl in the refrigerator for 30 mins.
Finally, dust the cocoa powder over the set cream. Garnish with the bourbons.
Place in the refrigerator and serve cool. You can garnish with chocolate chunks too or walnuts.
