- Pour the batter into the prepared baking tray and spread evenly into the corners using the back of the spatula.
- Bake for about 12 minutes until a toothpick inserted into the center comes out clean.
- Take a parchment paper and sprinkle with cocoa powder. This helps the cake not stick. Flip the cake over the paper. Remove the parchment paper it was baked with.
- While still hot roll with the parchment paper inside. You will have to do it while is still hot/warm otherwise it cracks. Let cool completely.
- Prepare the filling. Place chocolate and cream in a heatproof bowl and place over a pan with simmering water. Melt over low heat.

- Unroll the cake and spread the chocolate filling evenly over the cake.
- Roll the cake back up. Refrigerate for at least 1 hour before serving.
