Servings: 10-12
Start to finish: 1 hour 45 minutes (Plus at least 6 hours to chill)
12 ounces bittersweet chocolate, broken into 1-inch pieces
16 tablespoons unsalted butter
6 large eggs
1 cup (7 ounces) sugar
1/2 cup water
1 tablespoon cornstarch
1 tablespoon vanilla extract
1 teaspoon instant espresso powder
1/2 teaspoon salt
Adjust oven rack to middle position and heat oven to 275 F. Spray 9-inch springform pan with vegetable oil spray. Microwave chocolate and butter in bowl at 50 percent power, stirring occasionally, until melted, about 4 minutes. Let chocolate mixture cool for 5 minutes.
Whisk eggs, sugar, water, cornstarch, vanilla, espresso powder, and salt in large bowl until thoroughly combined, about 30 seconds. Whisk in chocolate mixture until smooth and slightly thickened, about 45 seconds. Strain batter through fine-mesh strainer into prepared pan, pressing against strainer with rubber spatula or back of ladle to help batter pass through. Gently tap pan on counter to release air bubbles; let sit on counter for 10 minutes to allow air bubbles to rise to top. Use tines of fork to gently pop any air bubbles that have risen to surface. Bake until edges are set and center jiggles slightly when cake is shaken gently, 45 to 50 minutes.
Let cake cool in pan on wire rack for 5 minutes; run thin knife around edge of pan to loosen cake. Let cake cool on rack until barely warm, about 30 minutes. Cover cake tightly with plastic wrap, poke small hole in top, and refrigerate until cold and firmly set, at least 6 hours or up to 2 days. Remove sides of pan and slide thin metal spatula between cake bottom and pan bottom to loosen, then slide cake onto platter. Let cake stand at room temperature for 30 minutes before serving.
