Make this when you want an impressive yet approachable dessert for gatherings, cozy movie nights, or when you simply need a little luxury on an ordinary evening.

Finishing
Instructions
- Preheat and prep the pan
Preheat your oven to 375°F (190°C). Line a 10 by 15 inch rimmed baking sheet with parchment paper and lightly grease the paper to help the sponge release easily after baking.
- Whip eggs to ribbon stage
In a heatproof bowl, whisk the eggs, granulated sugar, and vanilla extract. Set the bowl over a pot of simmering water (double boiler) and whisk constantly until the sugar dissolves and the mixture feels warm. Transfer to the stand mixer and beat on high until the batter forms thick ribbons that fall slowly and hold for a few seconds.
- Fold dry ingredients gently
Whisk the flour, cocoa powder, salt, and baking powder together. Add the dry ingredients to the egg mixture in three additions, folding gently after each until just combined to avoid deflating the batter.
- Bake and cool for rolling
Pour the batter into the prepared pan and spread it gently to the edges. Bake for 12 minutes, or until the top is set and springs back lightly. Immediately turn onto a clean kitchen towel dusted with powdered sugar, peel off the parchment, and roll the cake up gently but firmly, including the towel. Let it cool completely before unrolling.
- Make chocolate buttercream
Beat the softened butter until smooth. Add powdered sugar, cocoa powder, salt, and vanilla on low speed to avoid dust, then increase speed and mix until fluffy. Add heavy cream a little at a time until you reach a spreadable, pipeable consistency.
- Whip the cream
In a chilled bowl, whip the heavy cream and granulated sugar until stiff peaks form. This will sit on top of the buttercream for contrast in texture.
- Assemble the roll
Unroll the cooled cake and spread a thin layer of chocolate buttercream over the surface, leaving a small border along one short edge. Dollop with whipped cream and gently roll the cake back up, using the parchment to guide it into a tight log.
- Chill and set
Wrap the roll tightly in plastic wrap and chill for at least 30 minutes, or up to overnight, so the flavors meld and the slice holds its shape.
- Serve and garnish
Trim the ends if desired, slice with a sharp knife, and garnish each slice with a drizzle of chocolate buttercream and a sprinkle of dark chocolate chips or shaved chocolate.
Substitutions and variations
- Use gluten-free all-purpose flour blend in place of regular flour for a gluten-free version, and add 1/4 teaspoon xanthan gum if not included in the blend.
- Swap cocoa powder for instant espresso powder for a mocha twist that deepens the chocolate flavor without adding more liquid.
- Replace heavy cream in the whipped cream with coconut cream (chilled overnight) for a dairy free option.
- If you do not have a kitchen scale, you can use 1 cup all purpose flour plus 2 tablespoons cocoa powder, but weighing is more precise.
Chloe's tips
- Measure flour correctly by spooning it into the cup and leveling off; this prevents a dense cake.
- Do not skip the cooling step before unrolling, or the cake may tear.
- If the buttercream stiffens in the fridge, warm the bowl slightly and stir for a smoother texture.
- For extra flavor, brush the cake with a light syrup of coffee and sugar before adding buttercream.
How to store it
- Store the wrapped roll in the refrigerator for up to 3 days. Bring to room temperature for 20 to 30 minutes before serving for the best texture.
- Keep leftover slices in an airtight container in the fridge for up to 2 days; freeze for up to one month if needed.
Serving suggestions
Serve these elegant slices on a simple platter with fresh berries and a dusting of cocoa for a showstopping yet easy dessert.
- Place one rolled slice on a small plate.
- Add a dollop of whipped cream and a few fresh raspberries on the side.
- Finish with a drizzle of melted chocolate and cocoa dust.
Frequently asked questions
Why did my cake crack when rolling?
The cake may have been too warm or over-baked. Let it cool fully on the towel and roll gently while still slightly warm for flexibility.
Can I make the buttercream ahead of time?
Yes, you can make the buttercream 2 to 3 days in advance and store it in the refrigerator. Bring it to room temperature and re whip before using.
What if I do not have a stand mixer?
You can whip the eggs and sugar with a handheld electric mixer and fold the dry ingredients by hand; it will take a little more effort but still works well.
Can I add nuts or chocolate chunks to the batter?
It is best to avoid adding nuts or large mix-ins, as they can interfere with the even rise and make rolling difficult.
