Here, in the U.S., they are known as Swiss or jelly rolls, but in Sweden they go under the name “rulltårta” (rolled up cake) and is commonly served with coffee.

“Rulltårta” is the ultimate picnic take-along, and if you fill it with berries you have the perfect summer dessert. We found this delicious recipe on alltommat.se

pread the batter over the paper and bake in the middle of the oven for about 5 minutes.
Pour some sugar over the “cake”. Let it cool.
Beat the cream lightly, add the raspberries and beat till it’s a firmer cream and the berries are distributed evenly throughout.
Spread the raspberry cream over the cake and begin rolling it (from one long side to the other).
Roll the cake in the paper and let it rest with the “seam” down.
