For the Whipped Cream Filling:

- 2 tablespoons powdered sugar

Instructions
- Preheat your oven to 350°F. Carefully line a 15x10-inch jelly roll pan with parchment paper, ensuring some overhang on the sides for easy cake removal.
- In a medium bowl, sift together the flour, cocoa powder, baking powder, and salt. Take your time to ensure no lumps remain.
- Using an electric mixer, beat the eggs and granulated sugar on high speed. Continue beating for about 5 minutes until the mixture becomes thick, pale, and falls in ribbons when you lift the beaters.
- Gently fold in the vanilla extract, vegetable oil, and milk. Use a spatula and be careful not to deflate the beautiful egg mixture.
- Gradually sift the dry ingredients over the wet mixture. Fold gently with a spatula, treating the batter as delicately as a soufflé.
- Pour the batter into the prepared pan, spreading it evenly. Tap the pan gently on the counter to release any trapped air bubbles.
- Bake for 10 to 12 minutes. The cake is done when it springs back when lightly touched in the center.
- While the cake bakes, prepare a clean kitchen towel by dusting it generously with powdered sugar.
- Immediately after baking, turn the cake out onto the prepared towel. Carefully peel off the parchment paper.
- Starting from a short end, roll the cake up with the towel inside. Let it cool completely on a wire rack to help it maintain its shape.
- For the filling, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
- Once the cake is completely cool, gently unroll it and spread the whipped cream evenly over the surface.
- Carefully roll the cake back up, this time without the towel.
- To make the ganache, heat the heavy cream in a small saucepan until it just begins to simmer. Pour over chocolate chips in a heatproof bowl.
- Let the chocolate and cream sit for a minute, then stir until smooth and glossy.
- Place the rolled cake on a wire rack set over a baking sheet. Pour the ganache over the cake, allowing it to drip down the sides.
