This Christmas my parents wanted me to bake a light and "easy" cake for our Swedish Christmas dinner so we thought of a chocolate filled rulltårta. Rulltårta, or roll cake in Swedish, is known in the US as Swiss roll, while we do not have such a cake in Switzerland. Maybe another Swiss-Swedish confusion :-p
So rulltårta is basically a very thin sponge cake filled with either (whipped) cream and berries or with chocolate cream. Here I went for chocolate cream. It was a totally new experiment and turned out to be a great dessert, for Christmas or any time of the year with coffee in the afternoon.
The recipe is short and the chocolate filling easy to make. The only tricky part is 1) making sure the cake does not overbake, else it will crack when rolled, and 2) flipping the cake upside down on parchment paper, but if you don't hesitate it will be fine ! So try it and enjoy :-D
Recipe for a chocolate filled rulltårta:
2 dl sugar
2 dl flour
2 tsp baking powder
0.5 dl milk
Beat sugar and eggs until white. Mix flour and baking powder, then carefully add it to the batter and mix. Add milk last and mix gently. Pour the batter on a sheet pan covered with parchment paper (it's the flat pan that you have in your oven). Bake 4.5-5 min at 250 C. Spread sugar on the cake and flip it upside down on parchment paper covered with sugar. Detach the parchment paper very carefully so as not to break the cake: you can spread some water on the paper, it will help the cake detach from it.
2.25 dl light cream (15% fat)
3 tbsp sugar
3-4 tbsp cocoa
2.25 tbsp maizena
23 g butter
