Can't believe I missed this in January - a must-try for next festive season!
This New Orleans-style cake, a cousin of Hungary's Dobos torte, came to the United States in the 1930s and was transformed into doberge (pronounced DOH-bash) cake. Many countries now associate this bake with Epiphany in January, the end of the Christmas season.
It's an American recipe, so dig out your measuring cups for this recipe (serves 12-14). There's a lot of ingredients, and it takes a while to make, but it's worth it.
For the Chocolate Filling, Lemon Curd, and German Buttercream
1 1⁄4 cups plus 2 tbsp sugar, divided
2 tbsp. plus 2 1⁄2 tsp. constarch, divided
1 tbsp. cocoa powder
1 1⁄2 tsp. kosher salt, divided
5 large eggs, divided, plus 5 large egg yolks, divided
3⁄4 cup heavy cream
1 3⁄4 cups whole milk, divided
1 vanilla bean, halved, each half split and seeds scraped
4 oz. (70 percent) dark chocolate, finely chopped
6 tbsp. unsalted butter, divided, cubed, plus 1 lb. (4 sticks) softened
1⁄4 cup lemon zest
1⁄2 cup lemon juice
For the Cake, Simple Syrup, and Chocolate Ganache
3 1⁄2 cups (1 lb. 1⁄4 oz.) cake flour
2 tbsp. baking powder
1 cup buttermilk
1 tbsp. sour cream
1 tsp. vanilla extract
3 cups sugar, divided
12 tbsp. unsalted butter, softened
1 1⁄4 tsp. kosher salt, divided
1 tsp. finely grated lemon zest
4 large eggs, separated
12 oz. (70 percent) dark chocolate, finely chopped
1 1⁄2 cups heavy cream
Make the chocolate filling: In a medium heavy-bottomed saucepan, whisk 1⁄4 cup sugar with 1 tbsp. plus 1 tsp. cornstarch, cocoa powder, and 1 tsp. salt.
Whisk in 1 egg until smooth, then whisk in the cream, 3⁄4 cup milk, and seeds from 1⁄2 the vanilla bean. Place the pan over medium heat and cook, stirring constantly, until the filling thickens to the consistency of loose pudding, 8 to 10 minutes.
Remove the pan from the heat and stir in the chocolate and 2 tbsp. cubed butter until smooth. Scrape the filling through a fine sieve into a bowl. Press a sheet of plastic wrap directly onto the surface of the filling and refrigerate until chilled and thickened, at least 4 hours.
Make the lemon curd filling: In a medium heavy-bottomed saucepan, whisk 1⁄2 cup sugar with 1⁄2 tsp. salt, 3 whole eggs, and 4 egg yolks until smooth, then whisk in the lemon zest and juice. Place the pan over medium heat and cook, stirring constantly, until the filling thickens to the consistency of loose pudding, about 5 minutes.
Remove the pan from the heat and stir in 4 tbsp. cubed butter until smooth. Scrape the filling through a fine sieve into a bowl. Press a sheet of plastic wrap directly onto the surface of the filling and refrigerate until chilled and thickened, at least 4 hours.
Make the German buttercream: In a small heavy-bottomed saucepan, whisk 1⁄2 cup plus 2 tbsp. sugar with 1 tbsp. plus 1 1⁄2 tsp. cornstarch, 1 whole egg and 1 egg yolk, and remaining vanilla seeds until smooth, then whisk in the milk. Place the pan over medium heat and cook, stirring constantly, until the mixture thickens to the consistency of loose pudding, 6 to 8 minutes.
Remove the pan from the heat and scrape the pudding through a fine sieve into a bowl. Press a sheet of plastic wrap directly onto the surface of the pudding and refrigerate until chilled and thickened, at least 2 hours.
Scrape the vanilla pudding into the bowl of a stand mixer fitted with a paddle and turn the mixer on to medium speed. Add 1 tablespoon of the softened butter and let the butter disappear into the pudding before adding another tablespoon. Repeat adding butter in this manner until the buttercream is smooth, pale, and fluffy, about 8 minutes from start to finish. (The buttercream will look curdled at first, but will smooth out by the time the last of the softened butter is added.)
Scrape the buttercream into a bowl and cover with plastic wrap. If not using right away, refrigerate the buttercream for up to 5 days. Allow it to return to room temperature and beat it again in the stand mixer until fluffy before using.
Make the cake layers: Heat the oven to 180°. Line three 8-inch round cake pans with parchment paper circles and spray with nonstick baking spray. Sift the cake flour into a large bowl, then whisk in the baking powder. In a liquid measuring cup, whisk the buttermilk with the sour cream and vanilla until smooth. In the bowl of a stand mixer fitted with a paddle, cream 2 cups sugar with the butter and 3⁄4 tsp. salt on medium speed until pale and fluffy, about 3 minutes.
Add the lemon zest followed by the egg yolks, adding one at a time, beating well after each addition until smooth. Reduce the mixer speed to low and alternately add the dry ingredients in 3 batches and the wet ingredients in 2 batches, beginning and ending with the dry ingredients, and beat until the batter just comes together.
Using a rubber spatula, stir the batter again until smooth then scrape it into a large bowl. Clean and dry the bowl, return to the stand mixer, and fit with a whisk. Add the egg whites to the bowl and beat on medium-high speed until soft peaks form. Scrape the egg whites into the cake batter and gently fold until combined and smooth.
Divide the cake batter among the prepared cake pans and, using a small offset spatula, spread the batter evenly in each pan. Bake the cakes, rotating the pans halfway through cooking, until lightly browned and a toothpick inserted in the middle of each comes out clean, 20 to 22 minutes. Transfer the pans to a rack and let the cakes cool completely, then invert the cakes onto the rack and remove the parchment paper.
Once the cakes are completely cooled, use a serrated knife to halve each horizontally to produce 6 cake layers total. While the cakes cool, make the simple syrup: In a small saucepan, combine the remaining 1 cup sugar with 1 cup water and bring to a boil, stirring to dissolve the sugar. Boil the syrup for 5 minutes, then remove from the heat and let cool completely.
Assemble the cake: Using a pastry brush, brush each cake layer with some of the simple syrup, discarding any leftover syrup. Using a small offset spatula, spread 3 cake layers each with one-third of the chocolate filling. Spread 2 cake layers each with half the lemon filling.
Place 1 chocolate-covered cake layer on a cake stand, then quickly stack the remaining cake layers, alternating the lemon and chocolate fillings, and ending with the final, plain cake layer. Refrigerate the stacked cakes for 30 minutes. Using a small offset spatula spread the top and sides with the German buttercream until smooth. Place the cake in the freezer for 30 minutes.
While the cake is in the freezer, make the ganache: Place the chocolate in a medium bowl. In a small saucepan, heat the cream and 1⁄2 tsp. salt over medium until it begins to bubble at the edges.
Remove the pan from the heat, pour the hot cream over the chocolate, and let stand, undisturbed, for 1 minute. Whisk the chocolate and cream from the center until the ganache is smooth and shiny.
Remove the cake from the freezer and slowly pour the ganache over the top of the cake, using the offset spatula to guide and spread it over the side, until the cake is completely coated in the ganache. (You can also let the ganache drip down the side of the cake and set naturally, if you like.)
Let the cake stand for about 10 minutes to allow the ganache to set before serving. Store the cake, wrapped in plastic wrap, in the refrigerator for up to 1 week (allow it to return to room temperature before serving).

We're becoming experts in sugar free baking, so we thought you'd like to hear our top tips for trying it at home!
· Use raw cacao nibs and raw cacao powder instead of chocolate. Surprisingly, even dark 70% cocoa chocolate may contain sugar, as can cocoa powder. Raw cacao has a rich flavour and is a good source of minerals (e.g. like iron)
· Use fruit purées instead of syrups, treacle or honey. Syrups add a gooey texture to traybakes, cookies and tarts which is hard to recreate... However, fruit purées supply sweetness and moisture and can make a useful alternative.
· Use wholemeal flour instead of refined white flour, or go totally gluten free. Although it may not be a sugar itself, refined white flour is digested really quickly, which may aggravate blood sugar levels. Use wholemeal flour to slow the rate at which your body absorbs all forms of sugar. The best cake flours for gluten free purposes are almond flour coconut flour (the cheaper of the two), or a mix.
· Use vanilla pods instead of vanilla extract. They're relatively small in terms of their sugar contribution in cakes, but they're still a processed sugar you may choose to avoid. You can make the pricey pod go a little further but removing the seeds and infuse the pods in yoghurt or cream.
· Use homemade fruit jams instead of store-bought jam, compotes or conserves. Even jams and conserves with no added sugar are still a concentrated source due to their high fruit content. You have greater control over the sugar content when you make it yourself, and there are zero sugar recipes if you search online.
· Use lighter toppings in place of icing, buttercream and frosting - these little extras can more than double the calories per portion. Instead, sprinkle your cake lightly with cacao powder, cinnamon or ground ginger. Use cream cheese topping flavoured with citrus zest, or a fresh cream filling with some seasonal fruit.
And if it all gets too much, we deliver!
