Marmorized Chocolate Cake

Preheat the oven to 180°C (medium)

Grease a 24cm x 38cm baking dish with butter

Make the filling: in a large saucepan, combine all the ingredients and cook over high heat, stirring constantly until thickened

Let it cool completely, covered with plastic wrap. Reserve

Prepare the dough: using an electric mixer, beat the egg whites until stiff peaks form

Add the sugar, granulated, at intervals, until stiff peaks form

Beat in the yolks and mix until smooth

Remove from the mixer and gradually add the flour with yeast, sifted together

Divide the dough in half

Sift the cocoa powder over one portion and mix

Distribute spoonfuls of the white dough throughout the prepared baking dish

Repeat the procedure with the chocolate dough

Use a fork to spread the two doughs, making circular motions to create a marbled appearance

Place in the preheated oven until a toothpick inserted into the center comes out clean (about 35 minutes)

Remove from the oven and let cool completely

Turn onto a paper-lined surface or a cloth, and trim the edges

Distribute the reserved chocolate filling over the entire cake, leaving a 3cm border

Roll up the cake along its longest edge

Serve at room temperature
