We call this thing Towel Roll because of its shape. The trending pastry has won over young people for years, and has various fillings. I made the basic chocolate version even without Oreo, which is considered as a basic flavor nowadays to go with coco, just to practice.
The crepe is the first step. combine butter, egg, sugar, milk, coco powder, cake flour. Mix well put in fridge for 2 hours. Remember to cover the crepe mix with plastic wrap to absorb granules since the crepe needs to be super smooth.
Then choose a non-stick pan, heat up without oil on the lowest. Wait till you see little babbles. Repeat.
Lay 5 wraps together if you wanna one layer, or 3 for 2 layers. Add on whipped cream. Fold and roll. Let it cool in the fridge for 3-4 hours. Sprinkle some coco powder at the end.
Serve and enjoy!
