Preheat the oven to 350°F (175°C). Grease a 10×15-inch baking pan and line it with parchment paper.

In a large mixing bowl, beat the eggs with the granulated sugar using an electric mixer on medium speed until the mixture doubles in volume and becomes thick and pale, about 8-10 minutes.

Carefully sift the all-purpose flour and salt into the egg mixture a little at a time, gently folding with a spatula until just combined.

In a small bowl, combine the melted butter and vanilla extract. Slowly pour this mixture into the batter while gently folding it in until smooth.

Pour the batter into the prepared baking pan, smoothing it into an even layer.

Bake in the preheated oven for 12-15 minutes, or until the cake is golden brown and springs back when lightly touched.

Let it cool in the pan for 5 minutes before inverting onto a clean kitchen towel dusted with powdered sugar. Roll the cake with the towel while it's still warm and allow it to cool completely.

Once cooled, gently unroll the cake, spread your favorite filling over the surface, and carefully reroll it. Slice and serve.
