An IMPRESSIVE 16-Layer Brazilian Chocolate Cake Roll filled and frosted with chocolate ganache and garnished with berries. A modern version of the classic seventeenth century “Bolo de Rolo” from my home state of Pernambuco.

About Bolo de Rolo

This 16-Layer Brazilian Chocolate Cake Roll, known in Brazil as “Bolo de Rolo de Chocolate,” is an unique delicacy from the northeastern Brazilian state of Pernambuco.

It is a jelly roll-like cake with some distinctive characteristics: its numerous and fine layers made up of thin sheets of chocolate cake… alternating with a rich chocolate ganache filling.

Our Brazilian Chocolate Cake Roll is one of the modern variations on the classic centuries-old “Bolo de Rolo tradicional (a white cake roll filled with melted guava paste and sprinkled on top with a dusting of granulated sugar).

In fact, “bolo de rolo” is so important to the culture and gastronomy of Brazil that in 2008 Pernambuco passed a law to officially designate it as a cultural legacy of the state… a frequent highlight on the menus of most cafés, bakeries, some restaurants, and even food venues at the airport.

Our version is prepared with the same ingredients used for the classic, except for the addition of cocoa powder to the cake batter… as well as a rich chocolate ganache that replaces the traditional melted guava paste for the filling.

The chocolate cake roll is so popular that has been imported by special order to many different countries around the world such as Portugal, England, France, Saudi Arabia, and Japan.

In Brazil, one can encounter “bolo de rolo” with various different fillings (chocolate, dulce de leche, sweet prune paste, coconut, passion fruit, and so on).

But the only two things that never change are: the thinness and the large number of its many layers.

Finally, our 16-Layer Brazilian Chocolate Cake Roll can either be served as a dessert or snack all by itself, or warmed up and served with ice cream.

It also happens to be the perfect companion for cafezinho (a small cup of strong coffee). 😉

How To Make 16-Layer Brazilian Chocolate Cake Roll (Bolo de Rolo de Chocolate)

Preheat the oven to 350° F.

Prepare the cake batter: In the bowl of a mixer fitted with the paddle attachment, beat butter at medium speed for about 2 minutes.

At a slow speed, gradually add the sugar, then beat for 3 to 5 minutes or until mixture is homogeneous and creamy.

Add the yolks one by one, beating at low speed after each addition until just incorporated.

Then, at low speed, gradually add flour and cocoa powder until you have a homogeneous cake batter, scraping down the batter from the sides of the bowl a few times.

Beat the egg whites until stiff. Using a spatula, gently fold in the egg whites (do not beat).

Grease and flour 8 (10 x 15-inch) jelly roll pans and pour about 1 cup of batter into each. Spread the batter into a very thin and uniform layer covering the bottom of each sheet pan using an offset icing spatula.

Bake the first layer of cake for 3 1/2 to 4 minutes (but do not let the cake brown) and reserve the others.

MEANWHILE, prepare the cake filling. Heat heavy cream in the microwave to just before the boiling point.

Pour into a bowl with chocolate chips and stir well until chocolate has completely melted and is smooth. Reserve close to a warm place so that the chocolate ganache won’t harden.

Remove cake from the oven and place baking sheet on a counter lined with a clean kitchen linen or towel.

Since this cake is thin and delicate, here is a great technique to release it from the pan without breaking the layer: Gently run a butter knife around the edges to loosen the cake from pan, making it easier to unmold.

Next, spread a kitchen towel on top or parchment paper. Then place an empty and larger baking sheet pan on top of this, right side up, to sandwich the cake and towel between the two pans.

Finally, flip the whole assemblage over in order to release the cake from the pan in which it was baked.

Remove what is now the top baking sheet pan, and then gently slide the bottom pan from beneath the cake and towel.

Working quickly, spread a thin layer of chocolate ganache on top of the cake and then roll: Starting from one end, pull up the two adjacent corners along the short length of the towel to initiate rolling of the edge of the cake.

Continue supporting/pushing the rolling edge of the cake with the towel beneath as needed until the cake layer is completely rolled.

The cake rolls more easily while still warm. Reserve rolled cake layer covered with towel so that it won’t dry.

Bake the next cake and then so on. Each rolled cake is then rolled into the next subsequent sheet of cake that has been spread with the chocolate ganache.

If any breaks appear in cake, press break with fingers to seal while it is still warm.

Slice the 2 edges of the cake to remove rough, imperfect ends. If desired, either use the remaining chocolate ganache as a topping or sprinkle cake with granulated sugar.

Serve Brazilian chocolate cake roll sliced into thin slices by itself, along with a cup of coffee, or slightly warmed and accompanied by a scoop of vanilla or coconut ice cream.

How to store chocolate cake roll

Store in an airtight container in the fridge for up to 7 days, or covered at room temp for up to 3 days. Freeze for up to 1 month. For this, wrap cake roll (without ganache) with parchment paper and then plastic wrap before freezing.

Let thaw before slicing!
