Ingredients
Method
Preparation
- Preheat your oven to 350°F (175°C). Line a jelly roll pan (10x15 inches) with parchment and lightly grease it.
Making the batter
- Beat the eggs and sugar until lighter and thicker. Stir in vanilla.
- In another bowl, whisk together the flour, cocoa, baking powder, and salt.
- Fold the dry mix into the egg mixture gently, then drizzle in oil or melted butter and fold until combined.
Baking the cake
- Spread the batter evenly into the prepared pan and bake for 10 to 12 minutes, until it springs back when tapped.
Rolling it
- Dust a clean kitchen towel with cocoa or powdered sugar. Flip the warm cake onto the towel, peel off the parchment, and roll it up gently with the towel inside.
- Let it cool rolled up.
Filling and serving
- Once cool, unroll the cake carefully. Spread the chocolate Swiss meringue buttercream filling evenly over the sponge, leaving a small border at the edges.
- Reroll without the towel, wrap, and chill for at least 30 minutes before slicing.
Notes
For best results, use room temperature eggs and avoid overmixing the batter to prevent a tough sponge. If you have any cracks in the cake, simply place the cracked side down when finished rolling.
