Merry Christmas – Chocolate Log Cake

“You may end up with extra butter cream for this recipe. Store the extra in the refrigerator and use it to frost cupcakes!” Jasline


Chocolate Swiss Roll:

½ cup plain flour

5 tablespoon good-quality cocoa powder

4 eggs

½ cup caster/granulated sugar

3 tablespoon hot, melted butter

Peanut Butter Frosting:

6 tablespoons icing sugar

5 tablespoons unsalted butter, at room temperature

5 tablespoons smooth, creamy peanut butter, at room temperature

Chocolate Meringue Butter cream:

½ cup dark chocolate

½ cup egg whites, room temperature

5 tablespoon granulated sugar

½ cup unsalted butter, diced and chilled


Chocolate Swiss Roll:

Grease a 9×15 inch sheet pan (0.5 inch in height), and line the bottom and the sides with 
parchment paper.

Preheat the oven to 375°F.

Sift the flour and cocoa powder together thrice. Set aside.

Place the eggs in a metal pot.

Whisk in the sugar until combined.

Set the pot over gentle heat and whisk constantly, until the mixture is foamy and the temperature 
is warm, that of baby’s milk.

Remove from heat and transfer the mixture into a mixing bowl.

Whip the mixture with an electric mixer on high speed until the mixture is no longer foaming and 
the bubbles disappeared.

Whip until the mixture has tripled in volume and is thick and rich.

Switch to the lowest speed and whip for 1 minute, until the mixture leaves a trail for a short 
while, before merging with the mixture.

Sift the flour mixture over the egg mixture in three parts, gently folding the flour into the egg 
mixture until thoroughly combined.

There shouldn't be any flour pockets visible and do not over-mix.

Pour a couple tablespoonfuls of cake batter into the hot, melted butter and fold until the butter 
has been incorporated into the cake batter.

Pour the mixture back into the cake batter and fold it in gently.

Transfer the cake batter into the sheet pan.

Tilt the sheet pan so the batter spreads out evenly and drop it several times on the counter top 
to burst the uneven air bubbles.

Bake in the middle rack for 10 to 15 minutes until the cake springs back when touched gently 
and a skewer inserted into the center of the cake comes out dry.

While the cake is baking, sprinkle a clean tea towel with granulated / caster sugar.

When the cake is done, remove it from the oven and set it aside for 1 minute.

Turn the sponge out onto the tea towel with sugar.

Roll up the cake firmly from the shorter end and set it aside to cool completely.

Peanut Butter Frosting:

In a medium bowl, use an electric mixer and beat the icing sugar, butter and peanut butter until 
smooth and creamy.

Set it aside.

Chocolate Meringue Butter cream

Place the dark chocolate in a heatproof bowl.

Place the heatproof bowl over a pan of simmering water, ensuring that the water do not touch 
the bottom of the heatproof bowl.

Stir the chocolate occasionally until all the chocolate has melted.

Alternatively, microwave the chocolate on medium-high, checking the chocolate every 30 
seconds, until the chocolate looks shiny.

Stir the chocolate until all has melted, heating it if needed.

Leave the bowl of chocolate aside to cool to room temperature, stirring occasionally.

Place the egg whites in a different heatproof bowl.

Place the bowl over a pan of simmering water, again ensuring that the water do not touch the 
bottom of the bowl.

Use a whisk and whisk the egg whites, adding the sugar in 3 batches.

Whisk the egg whites + sugar mixture until the mixture is warm like baby’s milk and that all the 
sugar has dissolved.

Test it by dipping your fingers into the egg whites and rubbing it against your fingers to ensure 
all sugar has dissolved.

Remove the egg whites mixture from the heat.

Using an electric beater now, beat the egg whites mixture on high speed until the egg whites 
had cooled down completely and the mixture is thick and glossy (stiff peaks).

The egg whites will not slide even when the bowl is overturned.

Beat in the unsalted butter cube by cube.

The mixture will become very watery and seems like the butter cream has failed.

But fret not!

After adding all of the butter, the mixture will gradually come together and become a creamy 
and smooth butter cream.

Add in the cooled, melted chocolate (hot, melted chocolate may end up cooking the eggs, so 
make sure it’s completely cooled!).

Beat with the electric mixer on low speed until fully incorporated.


Unroll the cooled Swiss roll.

Spread an even layer of Peanut Butter cream on the Swiss roll and roll it up to form a log.

Cut out a short section of the Swiss roll at a diagonal to from the branch.

Spread some Chocolate Meringue Butter cream on one end of the branch and join it to the 
remaining section of the Swiss roll.

Spread a thin layer of Chocolate Meringue Butter cream all over the log cake.

Refrigerate it for 10 minutes.

Spread an even layer of the remaining Chocolate Meringue Butter cream all over the log cake.

Refrigerate for 30 minutes.

Using a fork, draw lines all over the log cake and use a skewer to draw a spiral on the ends of 
the log cake.

Decorate with Christmas decorations.

Refrigerate until ready to serve.
