Why This Recipe Works
This recipe balances structure and indulgence by using egg whites for lift and melted bittersweet chocolate for depth. I’ve tested multiple fillings—guinness or coffee-based ganache—but the silky chocolate buttercream here delivers the creamiest texture without overpowering the sponge. The key is proper egg white aeration and precise rolling techniques.

Step-by-Step Instructions
-
Prepare Cake Batter
Beat egg yolks, butter, 1/3 cup sugar, and vanilla in a bowl until light. Set aside.
-
Whip Egg Whites
In a clean bowl, whip egg whites and cream of tartar until soft peaks form. Gradually add 1 cup sugar and continue beating until stiff, glossy peaks.
-
Combine and Bake
Gently fold 1/3 of egg whites into yolk mixture. Sift flour, cocoa, baking powder, and salt into the bowl. Add remaining egg whites in batches, folding until no streaks remain.
-
Roll Cake
Transfer batter to a parchment-lined jelly roll pan. Spread evenly. Bake at 350°F (175°C) for 10-12 minutes until surface cracks. Let cool 5 minutes before carefully peeling parchment and rolling cake in the pan to prevent collapse.
-
Make Filling
Beat butter, confectioners sugar, heavy cream, and chopped chocolate in a bowl until smooth. Transfer in piping bag with an open star tip.
-
Assemble and Frost
Unroll cake on silicone mat or parchment. Spread filling evenly to 1/2 inch from edges. Carefully re-roll and refrigerate 20 minutes before slicing diagonally.
Chef Tips for Perfect Results
- Use room-temperature butter for smoother aeration during filling preparation
- For optimal rise, whip egg whites in a smear-free bowl with no trace of grease
- Measure flour using spoon-and-level method to avoid overpacking
- Let cake cool partially (5 minutes) before rolling to maintain structure
- Use finely chopped chocolate in filling for even melting and distribution
Common Mistakes to Avoid
- Overmixing batter: This deflates egg whites, resulting in dense cake. Use gentle folding technique.
- Skipping parchment paper: The cake will stick and tear during rolling. Always line the pan.
- Underbaking cake: Check doneness at 10 minutes—edges should recede from pan.
- Liquid filling: Pipe filling immediately after making to prevent seeping into cake.
- Overfilling cake: Spread just 1/2 inch from edges when piping to avoid leakage during rolling.

Frequently Asked Questions
Can I use dairy-free alternatives?
Yes. Substitute heavy cream with coconut cream and butter with vegan alternative. Ensure dark chocolate has no dairy content.
How to tell if cake is done baking?
The surface will crack andbounce back when lightly touched. Insert a toothpicknear edge—it should exit clean with just crumbs.
The cake cracks when rolling. Why?
Underbaking or overfilling are usual causes. Bake until surface cracks naturally and fill only 1/2 inch from edges to prevent uneven weight distribution.
Can I make this cake ahead of time?
Yes. Freeze fully assembled cake for up to 3 months. Thaw overnight in refrigerator, then bring to room temperature for 1 hour.
What’s the best way to cut slices?
Use a sharp knife dipped in hot water and patted dry. Make diagonal cuts for better presentation and portion control.
