Instructions

1. 1

   Prepare your baking sheets

   Heat your oven to 200°C (390°F). Line two baking sheets with parchment paper and draw a 24cm circle on each using a cake tin as a template. Flip the parchment so the pencil mark faces down but remains visible. Lightly butter and flour the parchment inside the circles. You'll bake two or three layers at a time, depending on your oven, and reuse these sheets for each batch. Five layers total. One extra for the caramel top, so six layers to bake.

   If you only have one oven rack, bake one layer at a time. These sponges take six to eight minutes each. It feels slow, but each layer bakes so quickly that you'll find a rhythm.

   Whip the egg whites

   In a large, spotlessly clean bowl, beat the six egg whites with a pinch of salt until they hold soft peaks. Add half the sugar gradually, a tablespoon at a time, beating continuously. The meringue should be glossy and hold firm peaks that bend slightly at the tip. If the peaks flop over, keep going. If they look grainy and dry, you've gone too far. Glossy and firm, that's where you stop.

   Build the sponge batter

   In a separate bowl, whisk the six egg yolks with the remaining sugar and the Vanillezucker until thick, pale, and ribbon-like. When you lift the whisk, the batter should fall in a thick ribbon that holds its shape on the surface for a few seconds before dissolving. This takes three to four minutes with a hand mixer. Fold one third of the whipped whites into the yolk mixture to lighten it. Then sift the flour over the top and fold it in gently, adding the remaining whites in two additions as you go. Work quickly and lightly. Every unnecessary fold costs you air, and air is the only leavening this sponge has.

   Bake the sponge layers

   Spread a thin, even layer of batter inside each drawn circle, using an offset spatula. Thin means thin. About three to four millimeters. The batter should barely cover the parchment. You'll feel like it's not enough. It is. Bake for six to eight minutes until the sponge is golden and springs back when you touch the center. Remove immediately and slide the parchment onto a cooling rack. Repeat until you have six layers. Work quickly between batches because the batter will deflate as it sits.

   The layers don't need to be identical, but they should be as close to the same thickness as you can manage. Uneven layers mean uneven slicing later, and Dobostorte is a cake that shows every flaw when you cut it. That's part of its beauty and its challenge.
5. 5

   Trim the layers

   While the sponges are still slightly warm, use your 24cm cake tin as a guide and trim each layer into a clean circle with a sharp knife. Warm sponge trims cleanly. Cold sponge crumbles. Save the trimmings. You'll crush them later for the sides of the finished cake. Set aside the best-looking, most even layer for the caramel top. That layer needs to be flat and smooth because it will be on display.

6. 6

   Make the chocolate buttercream

   Melt the chopped dark chocolate in a heatproof bowl set over barely simmering water. Stir until smooth, then remove from the heat and let it cool to room temperature. It should be liquid but not warm to the touch. In a large bowl, beat the softened butter with the sifted powdered sugar and Vanillezucker until pale and fluffy, about four minutes. Add the two egg yolks one at a time, beating well after each. Pour in the cooled espresso. Then add the melted chocolate in a steady stream while beating on medium speed. The buttercream should be smooth, glossy, and hold its shape on a spoon.

   If the chocolate is too warm when it hits the butter, the buttercream will be soupy and thin. If it's too cold, it will seize into lumps. Room temperature, truly room temperature, is the secret. Touch the bowl. It should feel neutral against your skin, neither warm nor cool.
7. 7

   Make the caramel top

   This is the step that separates Dobostorte from every other layered cake. Place your reserved sponge layer on a sheet of lightly oiled parchment. Oil a large knife or offset spatula. Put the 150g sugar in a heavy saucepan over medium heat. Do not stir. Let the sugar melt from the edges inward, swirling the pan gently to distribute the heat. Watch the color. It will go from clear to pale gold to deep amber. The moment it reaches a rich amber, about the color of dark honey, add the tablespoon of butter, swirl once, and immediately pour the caramel over the reserved sponge layer. Spread it quickly with your oiled spatula into a thin, even sheet. You have about thirty seconds before it sets. While it's still slightly pliable, score the surface into twelve even wedges with your oiled knife, pressing firmly but not cutting all the way through. Once the caramel hardens completely, you won't be able to cut it without shattering.

   Gretel always said caramel rewards confidence and punishes hesitation. Have everything ready before you start: the oiled spatula, the oiled knife, the sponge layer in position. Once the sugar hits amber, there is no pause button.

   Assemble the Torte

   Place the first sponge layer on your serving plate or cake board. Spread a thin, even layer of chocolate buttercream over it, about three millimeters thick. Place the second sponge layer on top and press down gently. Repeat with buttercream and sponge layers until all five bottom layers are stacked. Don't rush the spreading. Each layer of cream should be smooth and uniform in thickness. This is Konditorei work: precision is the point.

   Coat the sides and finish

   Spread a thin layer of buttercream over the top and sides of the assembled cake. Crush the reserved sponge trimmings into fine crumbs with your hands or a rolling pin. Press the crumbs gently into the buttercream coating on the sides of the Torte, covering them completely. This gives the finished cake its traditional appearance: the clean caramel top, the layered cross-section visible only when you slice, and the crumb-coated sides holding everything together. Carefully set the scored caramel layer on top. Refrigerate the assembled Torte for at least one hour before serving. The buttercream needs to firm up so the layers hold together when you cut.

    Slice and serve

    Remove the Torte from the fridge twenty minutes before serving. Use a sharp knife dipped in hot water and wiped dry to cut along the scored caramel lines. Each slice should show five distinct sponge layers separated by four even bands of dark chocolate buttercream, crowned by that sheet of amber caramel. Clean the knife between every cut. Serve at cool room temperature. Mahlzeit!

Chef Tips

• •Use good dark chocolate with at least 70% cocoa solids. The buttercream depends on it. Cheap chocolate with too much sugar will make the filling cloying, and after five layers of it, that sweetness compounds fast. You want bitterness in the cream to balance the caramel on top.
• •Bake the sponge layers thin. Thinner than you think is right. Three to four millimeters of batter on the parchment before it goes into the oven. The finished layers should be flexible and almost delicate. If they're thick and cakey, the proportions of the whole Torte fall apart and you end up with too much sponge and not enough cream.
• •Score the caramel while it's still pliable. This is the moment everyone worries about, and the solution is simple: have everything ready before you cook the sugar. The sponge layer in position, the knife oiled, the spatula oiled. Confidence and preparation. Hesitate and you'll be trying to cut through glass.
• •Let the assembled Torte rest in the fridge for at least an hour, ideally two or three. The buttercream firms up and binds the layers together. Without this rest, cutting produces a mess instead of clean cross-sections.
• •A knife dipped in hot water and wiped dry will cut through the caramel top without shattering it. Clean the blade between every slice. This is the difference between serving a Torte and serving a pile of beautiful rubble.

Advance Preparation

• •The sponge layers can be baked one day ahead. Stack them between sheets of parchment, wrap tightly in cling film, and store at room temperature. They'll be slightly more pliable the next day, which makes assembly easier.
• •The chocolate buttercream can be made one day ahead and refrigerated. Bring it to room temperature and beat it briefly before using. It should be spreadable, not stiff.
• •The caramel top must be made and scored on the day of assembly. Caramel absorbs moisture from the air, so the longer it sits, the stickier it becomes. Assemble the morning you plan to serve.
• •The fully assembled Torte keeps in the fridge for up to three days, though the caramel may soften slightly. Remove twenty minutes before serving.
