August Daring Bakers: Dobos Torte

The August 2009 Daring Bakers' challenge was hosted by Angela of A Spoonful of Sugar and Lorraine of Not Quite Nigella. They chose the spectacular Dobos Torte based on a recipe from Rick Rodgers' cookbook Kaffeehaus: Exquisite Desserts from the Classic Caff├ęs of Vienna, Budapest, and Prague.

Dear Fellow Daring Bakers,
i was so thrilled this month that we were doing an actual cake. Further, i had an actual event to offload said cake. i'm thinking, tho, based on the recipe and activity on the boards that i could've gotten away with halving this recipe and making miniatures instead, and it would've come out fine. as it was, because i was attending a company lunch and feeding whoever was in attendance that day, i decided to double the cake recipe (to offset any flubbing of the layers as well). i knew the amount of butter cream was going to be enough, because i hate having extra. (i'm not an icing kinda girl...)

had i planned correctly, i would've done this challenge over two nights but as it was, one of the nights was date night and so my 4 hours after work the day before the picnic was spent sweating my ass off in the kitchen as Baltimore went thru a killer heat wave. in addition, Top Chef premiered that night and i had to watch because there were 3 local contestants, one of them being Bryan Voltaggio of VOLT. thru two degrees of separation, i had to cheer him on, plus i'm headed there for lunch this weekend. :)

my first layers looked ugly and the subsequent ones came out a tad thicker than i would've liked but still rather pretty. i flubbed majorly doing the caramel topping and even tho i liked the pix of other bakers' on the boards, i thought it was too cumbersome on top. the commute into work that morning with the cake in the passenger seat was dire for some reason. i decided to just break off the caramel pieces that weren't effed and stick them randomly on top. how's that for cumbersome?
my coworkers were rather impressed with the cake. i flecked the sides of the cake with some almonds. my account rep Steve said the cake was "rather spongey" and my office girlfriend Courtney preferred the cake cold. (in regards to that, i had left the cake out at room temp on day of picnic and there were some pieces leftover, which was put in the fridge. the next day, Courtney had a piece and it was firmer and the icing not as soft.)

Equipment
2 baking sheets
9” (23cm) spring form tin and 8” cake tin, for templates
mixing bowls (1 medium, 1 large)
a sieve
a double boiler (a large saucepan plus a large heat-proof mixing bowl which fits snugly over the top of the pan)
a small saucepan
a whisk (you could use a balloon whisk for the entire cake, but an electric hand whisk or stand mixer will make life much easier)
metal offset spatula
sharp knife
a 7 1/2” cardboard cake round, or just build cake on the base of a springfrom tin.
piping bag and tip, optional

Prep times

Sponge layers 20 mins prep, 40 mins cooking total if baking each layer individually.
Buttercream: 20 mins cooking. Cooling time for butter cream: about 1 hour plus 10 minutes after this to beat and divide.
Caramel layer: 10-15 minutes.
Assembly of whole cake: 20 minutes

Sponge cake layers
6 large eggs, separated, at room temperature
1 1/3 cups (162g) confectioner's (icing) sugar, divided
1 teaspoon (5ml) vanilla extract
1 cup plus 2 tablespoons (112g) sifted cake flour (SUBSTITUTE 95g plain flour + 17g cornflour (cornstarch) sifted together)
pinch of salt

Chocolate Butter cream
4 large eggs, at room temperature
1 cup (200g) caster (ultra fine or superfine white) sugar
4oz (110g) bakers chocolate or your favourite dark chocolate, finely chopped
2 sticks plus 2 tablespoons (250g) unsalted butter, at room temperature.

Caramel topping
1 cup (200g) caster (superfine or ultra fine white) sugar
12 tablespoons (180 ml) water
8 teaspoons (40 ml) lemon juice
1 tablespoon neutral oil (e.g. grape seed, rice bran, sunflower)

Finishing touches
a 7” cardboard round
12 whole hazelnuts, peeled and toasted
½ cup (50g) peeled and finely chopped hazelnuts
Directions for the sponge layers:

NB. The sponge layers can be prepared in advance and stored interleaved with parchment and well-wrapped in the fridge overnight.

1.Position the racks in the top and centre thirds of the oven and heat to 400F (200C).
2.Cut six pieces of parchment paper to fit the baking sheets. Using the bottom of a 9" (23cm) spring form tin as a template and a dark pencil or a pen, trace a circle on each of the papers, and turn them over (the circle should be visible from the other side, so that the graphite or ink doesn't touch the cake batter.)
3.Beat the egg yolks, 2/3 cup (81g) of the confectioner's (icing) sugar, and the vanilla in a medium bowl with a mixer on high speed until the mixture is thick, pale yellow and forms a thick ribbon when the beaters are lifted a few inches above the batter, about 3 minutes. (You can do this step with a balloon whisk if you don't have a mixer.)

4.In another bowl, using clean beaters, beat the egg whites until soft peaks form. Gradually beat in the remaining 2/3 cup (81g) of confectioner's (icing)sugar until the whites form stiff, shiny peaks. Using a large rubber spatula, stir about 1/4 of the beaten whites into the egg yolk mixture, then fold in the remainder, leaving a few wisps of white visible. Combine the flour and salt. Sift half the flour over the eggs, and fold in; repeat with the remaining flour.
5.Line one of the baking sheets with a circle-marked paper. Using a small offset spatula, spread about 3/4cup of the batter in an even layer, filling in the traced circle on one baking sheet. Bake on the top rack for 5 minutes, until the cake springs back when pressed gently in the centre and the edges are lightly browned. While this cake bakes, repeat the process on the other baking sheet, placing it on the centre rack. When the first cake is done, move the second cake to the top rack. Invert the first cake onto a flat surface and carefully peel off the paper. Slide the cake layer back onto the paper and let stand until cool. Rinse the baking sheet under cold running water to cool, and dry it before lining with another parchment. Continue with the remaining papers and batter to make a total of six layers. Completely cool the layers. Using an 8" spring form pan bottom or plate as a template, trim each cake layer into a neat round. (A small serrated knife is best for this task.)

Directions for the chocolate butter cream:

NB. This can be prepared in advance and kept chilled until required.

1.Prepare a double-boiler: quarter-fill a large saucepan with water and bring it to a boil.
2.Meanwhile, whisk the eggs with the sugar until pale and thickened, about five minutes. You can use a balloon whisk or electric hand mixer for this.
3.Fit bowl over the boiling water in the saucepan (water should not touch bowl) and lower the heat to a brisk simmer. Cook the egg mixture, whisking constantly, for 2-3 minutes until you see it starting to thicken a bit. Whisk in the finely chopped chocolate and cook, stirring, for a further 2-3 minutes.
4.Scrape the chocolate mixture into a medium bowl and leave to cool to room temperature. It should be quite thick and sticky in consistency.
5.When cool, beat in the soft butter, a small piece (about 2 tablespoons/30g) at a time. An electric hand mixer is great here, but it is possible to beat the butter in with a spatula if it is soft enough. You should end up with a thick, velvety chocolate butter cream. Chill while you make the caramel topping.

Lorraine's note: If you're in Winter just now your butter might not soften enough at room temperature, which leads to lumps forming in the butter cream. Male sure the butter is of a very soft texture I.e. running a knife through it will provide little resistance, before you try to beat it into the chocolate mixture. Also, if you beat the butter in while the chocolate mixture is hot you'll end up with more of a ganache than a butter cream!

Directions for the caramel topping:
1.Choose the best-looking cake layer for the caramel top. To make the caramel topping: Line a jellyroll pan with parchment paper and butter the paper. Place the reserved cake layer on the paper. Score the cake into 12 equal wedges. Lightly oil a thin, sharp knife and an offset metal spatula.
2.Stir the sugar, water and lemon juice in a small saucepan. Bring to a boil over a medium heat, stirring often to dissolve the sugar. Once dissolved into a smooth syrup, turn the heat up to high and boil without stirring, swirling the pan by the handle occasionally and washing down any sugar crystals on the sides of the pan with a wet brush until the syrup has turned into an amber-coloured caramel.
3.The top layer is perhaps the hardest part of the whole cake so make sure you have a oiled, hot offset spatula ready. I also find it helps if the cake layer hasn't just been taken out of the refrigerator. I made mine ahead of time and the cake layer was cold and the toffee set very, very quickly—too quickly for me to spread it. Immediately pour all of the hot caramel over the cake layer. You will have some leftover most probably but more is better than less and you can always make nice toffee pattern using the extra to decorate. Using the offset spatula, quickly spread the caramel evenly to the edge of the cake layer. Let cool until beginning to set, about 30 seconds. Using the tip of the hot oiled knife (keep re-oiling this with a pastry brush between cutting), cut through the scored marks to divide the caramel layer into 12 equal wedges. Cool another minute or so, then use the edge of the knife to completely cut and separate the wedges using one firm slice movement (rather than rocking back and forth which may produce toffee strands). Cool completely.

Angela's note: I recommend cutting, rather than scoring, the cake layer into wedges before covering in caramel (reform them into a round). If you have an 8” silicon round form, then I highly recommend placing the wedges in that for easy removal later and it also ensures that the caramel stays on the cake layer. Once set, use a very sharp knife to separate the wedges.

Assembling the Dobos
1.Divide the butter cream into six equal parts.
2.Place a dab of chocolate butter cream on the middle of a 7 1/2” cardboard round and top with one cake layer. Spread the layer with one part of the chocolate icing. Repeat with 4 more cake layers. Spread the remaining icing on the sides of the cake.
3.Optional: press the finely chopped hazelnuts onto the sides of the cake.
4.Propping a hazelnut under each wedge so that it sits at an angle, arrange the wedges on top of the cake in a spoke pattern. If you have any leftover butter cream, you can pipe rosettes under each hazelnut or a large rosette in the centre of the cake. Refrigerate the cake under a cake dome until the icing is set, about 2 hours. Let slices come to room temperature for the best possible flavour.

Storage
I (Angela) am quite happy to store this cake at room temperature under a glass dome, but your mileage may vary. If you do decide to chill it, then I would advise also using a glass dome if you have done. I should also note that the cake will cut more cleanly when chilled.

Variations
Shape: The traditional shape of a Dobos Torta is a circular cake, but you can vary the shape and size if you want. Sherry Yard in Desserts By The Yard makes a skyscraper Dobos by cutting a full-size cake into four wedges and stacking them to create a tall, sail-shaped cake. Mini Dobos would be very cute, and you could perch a little disc of caramel on top.

Flavour: While we both love the dark chocolate butter cream and this is traditional, we think it would be fun to see what fun butter creams you all come up with! So, go wild! Or, you could brush each layer with a flavoured syrup if you just want a hint of a second flavour. Cointreau syrup would be divine!

Nuts: These are optional for decoration, so no worries if you're allergic to them. If you don't like hazelnuts, then substitute for another variety that you like.

  3. Cakes are difficult even with normal weather, but for sure even harder when it's hot! That said, I am impressed you made a double batch. It came out really well!

  5. I actually kinda like the random caramel chunks it adds a quirky quality to it. It would have been a killer to make this on such a hot day, but you did superb because it looks delicious.

  6. Hey, it looks really good, and I do like the "spiky" look of the caramel :). Oh, I so hate driving with cake in the passenger seat, very nerve wracking!

  11. HAHAHAHHAHA I can just imagine how difficult it would be to commutede to work with a cake on the passenger seat. I agree with your co-worker regarding the cake being better if colder. I found that mine was too soft when served at room temperature as well.

  12. My eyes just had an orgasm.

    That's a seriously gooey looking cake. Gooey cake is a much-neglected art.

    Too many cakes these days, especially sponge-based ones, are simply too dry. Particularly the mass-produced, prepacked varieties, although that's not surprising. But many cakes should goo wildly in all directions, but don't. This apparently does. Applause.
