Grind the biscuits to a powder.
Add coffee powder, chocolate syrup and half the butter to it. Mix it well. If needed use little milk to make a dough. Keep it aside.
Mix the coconut, castor sugar, butter and cardamom powder together.
Grease a parchment paper with a little butter.
Take a ball of the dough, put it on the parchment paper and roll it.
Put the coconut filling over it, spread it evenly.
Now, slowly holding the parchment paper at one end, roll it into a cylindrical roll, put it in the parchment paper and refrigerate it for four to five hours.
Later, remove the parchment paper and cut into discs.
No bake swiss roll is ready to serve.
