In pastry school there was a course called "Classic Cakes and Tortes". After having worked in the most popular bakery in my home town, I thought, "Yes! finally I'll learn how to make all those fabulous layer cakes". Not exactly—what the culinary school had in mind was to teach us the traditional French and Austrian classics, not how to assemble a malted Milky Way mousse cake. Nonetheless, in making sacher tortes, opera tortes, and all those fancy Vienna coffeehouse cakes, I gained an appreciation for the oldies but goodies.

Though not out of the school recipe books, this cake reminds me of exactly the type of classic, low-to-the-ground type torte that we'd mix up in class. Toasted and ground hazelnuts form the flourless base to this dense crumbed cake, and orange zest complements the hazelnuts well. Whipped egg whites are folded in to the batter to lighten up the texture. Bread crumbs are an unusual but common addition to these types of rich nut tortes, as they not only help to lighten up the cake but were probably a way to stretch the nuts. Instead of standard bread crumbs, I folded in a handful of light and airy Japanese Panko crumbs.

Though not gluten-free, this flourless cake is outrageously moist. So much so that it's almost squishy—but who ever complains about a moist cake? No one. And what better to enrobe it but a smooth slick of espresso flavored chocolate ganache.

Ingredients

  • 8 large eggs, separated

  • 1 cup plus 2 tablespoons (8 ounces) granulated sugar, divided

  • 1 1/2 cups (7 1/2 ounces) toasted blanched hazelnuts

  • 1 tablespoon packed zest from 1 orange

  • 12 tablespoons (6 ounces) unsalted butter, softened

  • 1/4 teaspoon salt

  • 2 teaspoons vanilla extract

  • 3/4 cup (2 ounces) panko crumbs

  • 6 ounces bittersweet chocolate, finely chopped

  • 1/2 cup plus 2 tablespoons heavy cream

  • 1/2 teaspoon instant espresso powder

Directions

  1. Adjust oven rack to middle position and preheat oven to 350°F (175°C). Butter 9-inch springform pan. In food processor, pulse 1 cup sugar with hazelnuts until finely ground.

  2. In large bowl, whisk yolks, hazelnut mixture, zest, butter, salt, and vanilla until combined; set aside.

  3. Using stand mixer fitted with whip attachment, beat whites on medium-high speed to opaque. Slowly add remaining 2 tablespoons sugar and continue to beat to soft peaks. Fold meringue into hazelnut mixture, alternating with panko crumbs.

  4. Pour into pan and bake until center is just set and toothpick inserted into the middle comes out clean (see headnote), about 40 minutes. Let cake cool in pan for 15 minutes, then remove sides of pan and let cake cool completely before glazing.

  5. In heatproof bowl, heat chocolate with cream and espresso powder over barely simmering water, stirring until chocolate is melted and the mixture is smooth. Place cake on wire rack set in a rimmed baking sheet. Pour ganache over cake. Chill to set ganache. Serve.
