This classic dessert showcases Italian ingenuity at its most delicious. This Chocolaty Tiramisu boasts everything you love about the iconic Italian dessert—layers of moist, espresso-soaked ladyfingers sandwiched with rich, airy mascarpone cream—but with an added layer of luscious chocolate ganache. Whipping egg whites to stiff peaks before gently folding them into a whipped mixture of sugar, egg yolks, and mascarpone gave the classic, mildly sweet cheese filling a heavenly lightness. Briefly rolling the ladyfingers (rather than submerging them) in a potent mixture of coffee, espresso powder, and dark rum ensured that they turned perfectly tender and cake-like rather than soggy and were exceptionally flavorful. Using a 1:1 ratio of cream to chocolate for the ganache resulted in a soft, creamy texture even after chilling. This twist is sure to please tiramisu purists and chocolate lovers alike.
You can use pasteurized eggs here, but you may need to increase the whipping time in step 2 in order to get stiff peaks. Be sure to use the crisp, firm ladyfingers found in the supermarket cookie or international aisle, not the fresh, cake-like ladyfingers found in the bakery department. Twenty-four ladyfingers will weigh about 7 ounces. Do not use Whole Foods brand mascarpone for this tiramisu; the filling will be soupy. For a version without alcohol, you can substitute more coffee for the rum. Orange zest adds a pleasant floral brightness to this tiramisu; if you prefer a more traditional rendition, you can omit it. We call for an 8-inch square baking dish, but this tiramisu can also be made in eight 12-ounce serving glasses.
