Roll the cake while still warm with the towel inside to train it into shape, preventing cracks when adding filling.
Chill the ganache until thick before beating to achieve the right spreadable consistency.
Good to Know
Refrigerate wrapped cake roll for up to 3 days. Bring to room temperature 15 minutes before serving.
Assemble completely up to 2 days ahead. The flavors actually improve after overnight chilling.
Slice with sharp knife wiped clean between cuts. Dust with powdered sugar and cocoa just before serving.
Common Mistakes

FAQ
Can I make this without coffee?
Yes, substitute the coffee with an equal amount of water or milk. The coffee enhances chocolate flavor but isn't essential for the recipe's success.
What if my cake cracks when rolling?
Minor cracks are normal and will be hidden by the filling. If it cracks badly, press pieces together and continue - the plastic wrap will help hold it together.
How long will this keep refrigerated?
The assembled cake roll keeps for 3 days refrigerated. The texture is actually best after the first day as flavors meld and cake softens slightly.
