Combine warm milk and instant coffee together and mix until the coffee has dissolved completely.
Now, add butter, sugar and flour. Whisk until a smooth is achieved.
Heat the waffle cone maker on medium flame and pour 1-2 tbsp of batter onto it. Close the maker and cook it from both the sides by flipping the cone maker.
Remove carefully and shape it into a wafer roll using chopsticks. Be careful as it may still be hot, but shape it quickly before it hardens.
For coffee ganache, mix warm cream and instant coffee together. Pour it over chopped dark chocolate and let it sit for a minute. Whisk it until smooth ganache is achieved.
Pipe the coffee ganache in the wafer rolls and enjoy!
