This was adapted from a cooks Illustrated recipe. You don't need to add the coffee. But I can't imagine why you wouldn't! This flourless chocolate cake is the ultimate treat for someone on a gluten free diet. We have used Green & Blacks dark chocolate as it is gluten free. This is not health food. Eat only one piece and then find other people to share with. haha
honestly, I thought I would make this just for the blog. The cake actually caused me a bit of pain due to the large amounts of fat and sugar. if you have IBS, just eat the tiniest slice. k?
8 large eggs, cold
1 lb. organic dark baking chocolate, chopped
1/2 pound unsalted organic butter, cut into 1/2 inch chunks
1/4 cup strong coffee
1. Adjust oven rack to lower-middle position and heat oven to 325 degrees. Line bottom of 8-inch springform pan with parchment and grease pan sides. Cover pan underneath and along sides with sheet of heavy-duty foil and set in large roasting pan. Bring Kettle of water to boil.
2. Beat eggs with mixer at med/high speed until volume doubles to approximately 1 quart, about 5 minutes.
3. Meanwhile, melt chocolate and butter (adding coffee) in large heatproof bowl set over pan of almost simmering water, until smooth and very warm (about 115 degrees on an instant-read thermometer), stirring once or twice. (For the microwave, melt chocolate at 50 percent power for 2 minutes, stir, add butter, and continue heating at 50 percent power, stirring every minute, until chocolate and butter have melted and are smooth, another 2 to 3 minutes total.) Fold ⅓ of egg foam into chocolate mixture using large rubber spatula until only a few streaks of eggs are visible; fold in half of remaining foam, then last of remaining foam, until mixture is totally homogenous.
4. Scrape batter into prepared springform pan and smooth surface with rubber spatula. Set roasting pan on oven rack and pour in enough boiling water to come about halfway up side of springform pan. Bake until cake has risen slightly, edges are just beginning to set, a thin glazed crust (like a brownie) has formed on surface, and an instant-read thermometer inserted halfway through center of cake registers at 140 degrees, 22 to 25 minutes. Remove cake pan from water bath and set on wire rack; cool to room temperature. Cover and refrigerate overnight to mellow (can be covered and refrigerated for up to 4 days).
5. About 30 minutes before serving, remove springform pan sides, invert cake on sheet of waxed paper, peel off parchment pan liner, and turn cake right side up on serving platter. Sieve light sprinkling of confectioners' sugar or unsweetened cocoa powder over cake to decorate, if desired.
