Preheat the oven to 180-200℃, separate the egg yolks from the whites.
Beat the egg whites with a mixer for about 2-3 minutes until a stable foam, and mix the yolks with powdered sugar and beat for 1-2 minutes, combine the yolks with the whites and mix gently. Add the sifted flour in parts and gently stir the dough from bottom to top so that it does not settle.
Cover a baking tray with greased baking paper and spread the biscuit dough on it in an even layer. Place the baking sheet in the oven and bake at 180℃ until lightly browned, about 15 minutes.
When the cake is ready, remove it from the oven and immediately, while it is still hot, roll up the roll along with the parchment and leave to cool completely to reduce the risk of the sponge breaking while you are wrapping the jam in it.
After cooling, carefully unroll the roll, brush the entire surface of the sponge cake with jam and roll the roll back up.
You can serve this dessert with whipped cream or a scoop of ice cream. You can also sprinkle the roll with grated nuts or powdered sugar.
