Whip eggs and sugar until airy - about 3-4 minutes.
Carefully fold in baking powder and flour.
Spread the batter on a baking sheet lined with parchment paper, about 5-6 mm thick.
Bake for 8-9 minutes in a preheated oven at 200 degrees Celsius (392 degrees Fahrenheit) until the dough is firm and golden.
Remove and let cool.
Once cooled, sprinkle another piece of parchment paper with sugar (not included in the recipe), and flip the roulade onto it, gently pressing it into the sugar.
Whip the cream to soft peaks and fold in the skyr and vanilla sugar.
First spread strawberry jam and then the vanilla cream on the roulade base.
Sprinkle with finely chopped strawberries and chocolate.
Roll up the roulade.
Spread any leftover vanilla cream on the outside of the roulade and garnish with thin slices of strawberry - serve.
