This moist cake gets even better when served with vanilla ice cream or a dollop of whipped cream.

We have this on Christmas Eve. French recipe

This recipe must be prepared with natural cocoa powder. Dutch-processed cocoa will not yield the proper color or rise.

MAKES ONE 9-INCH CAKE, SERVING 12 TO 16

We recommend using either Callebaut Intense Dark L-60-40NV or Ghirardelli Bittersweet Chocolate Baking Bar, but any high-quality bittersweet or semisweet chocolate will work. If you’re refrigerating the cake for more than 1 hour in step 6, let it stand at room temperature for about 30 minutes before serving.

WHY THIS RECIPE WORKS:
Using ground nuts in place of some of the flour gave our rich, fudgy, flourless chocolate cake a sturdy enough texture to serve as the base of our chocolate-raspberry torte recipe. We combined raspberry jam with lightly mashed fresh raspberries for a tangy-sweet mixture that clung to the cake. And for the glaze, melting bittersweet chocolate with heavy cream created a rich-tasting, glossy ganache that poured smoothly over the cake and made the perfect topping to our chocolate-raspberry torte.

Serves 10 to 12

Do not use all-purpose flour. Our tasters unflatteringly compared a cake made with it to Wonder Bread. If your angel food cake pan does not have a removable bottom, line the bottom of the pan with parchment paper. In either case, do not grease the pan (or the paper).
