Preheat your oven to 400°F (200°C) and line a jellyroll pan with parchment paper
Using an electric mixer, beat the eggs in a bowl until they become light and fluffy, about 5 minutes.
Gradually add 1/2 cup of sugar, one tablespoon at a time, continuing to beat for another 5 minutes.
Mix in the salt, oil, and vanilla extract.
In a separate bowl, combine the flour and baking powder.
Gradually sift the dry mixture into the egg mixture, folding gently with a spatula.
Evenly spread the batter onto the prepared baking sheet.
Bake for 10 to 12 minutes, or until the cake is lightly browned.
On a flat surface, lay out a clean dish towel and sprinkle it with 2 teaspoons of sugar.
Carefully invert the baked sponge cake onto the towel, peeling off the parchment paper.
Gently roll the cake up with the towel and let it cool completely, about 1 hour.
Once cooled, carefully unroll the sponge cake.
Spread the chocolate hazelnut spread over the cake, leaving a small border around the edges.
Gently roll the cake back up, wrap it in plastic wrap, and refrigerate for 2 hours. Slice and serve.
