Japanese Chocolate Swiss Roll Cake instructions

Preheat the oven to 350F.
Line a parchment paper.
Heat water in a large pot (ensure that your pot is big enough to place your mixing bowl in) over the stove. Remove the pot from the stove right before the water starts simmering.
Put the eggs and sugar in the mixing bowl. Place the mixing bowl over the pot and start beating it using an electric hand whisk. When the mixture reaches body temperature, remove it from the pot and continue beating the mixture until it reaches a soft peak..
Microwave the milk for 5-10 seconds to warm it up a bit.
Put the milk inside the mixture and hand whisk it until blended.
Sift half the cocoa powder and the flour into the mixing bowl and hand whisk until well combined. Repeat with the rest of the flour and cocoa powder. Make sure it's well combined..
Pour the mixture into your baking pan. If there are air bubbles in your baking mixture, drop the pan to release the bubbles. Make sure the batter is evenly spread across the pan..
Bake the cake for about 12-14 minutes. Check the cake around 10 min, make sure the bottom doesn't overcook. The top should spring back softly..
While the cake is baking, you can start making the chocolate whipped cream.
Place the cocoa powder, sugar, and heavy cream into a bowl. Whip the ingredients together with an electric hand whisk until it reaches stiff peaks. Leave it aside.
Once the cake is done, remove it and drop it once again so that the cake does not shrink. Set the cake aside to cool down a bit but not completely cool because it will be difficult to roll. You need to roll the cake while it is still warm or else it will crack..
Flip the cake while it is still warm by placing a parchment paper and a baking tray on top and then flipping it over. Gently peel off the parchment paper..
While the cake is still warm, carefully roll the cake with the parchment paper and then set aside for it to cool down to room temperature. Make sure it cools down completely before applying the whipped cream or else the cream will melt..
After the cake is cooled, spread the whipped cream on the cake. Make sure to spread the cream thinner near the end of the cake and thicker near the beginning so that the cream doesn't spill over when it gets rolled up again..
Carefully re-roll the cake with the cream tightly with parchment paper and plastic wrap..
Place the cake in the fridge for at least an hour to chill before serving.

It is made by a light and airy chocolate cake base, rolled up with light cocoa whipped cream and piped with extra cream before serve. This cake recipe is easy to make and less time consuming compared to the frosted layered cakes. You can find a variety of flavors for a Swiss roll. My method of making Swiss roll leans towards the Japanese and Asian style, although classic Japanese roll cakes are very similar to a Western Swiss roll. Some of the classic flavors are vanilla, cocoa, chocolate, tiramisu, coffee, strawberry, lemon, raspberry, and so on.
