Preheat the oven to 375°F (190°C). Grease a 15×10 inch jelly roll pan and line it with parchment paper.

In a large bowl, whisk together eggs and granulated sugar until pale and fluffy (about 5 minutes).

Sift together flour, baking powder, and salt in another bowl. Gently fold into the egg mixture until just combined.

Fold in melted butter and vanilla extract.

Pour batter into the prepared pan and bake for 12-15 minutes or until golden brown.

While cooling, whip heavy cream with powdered sugar until stiff peaks form.

Once the cake cools slightly, invert it onto a powdered-sugar-dusted towel, spread whipped cream over the surface, and roll tightly using the towel.
