Preparation

Step 1

Heat oven to 350 degrees F. Coat 4 (4- to 4 1/2-inch) nonstick individual springform pans with baking spray. In a bowl, mix flour, sugar, cocoa powder, baking soda, and salt. In a second bowl, whisk sour cream, oil, egg, vinegar, and vanilla; stir in flour mixture. Spread in prepared pans. Bake 28 minutes. Let cool in pans on wire rack 5 minutes. Invert cakes onto wire rack; remove sides and bottoms of pans. Cool completely.
Sprinkle gelatin over water in a small saucepan; let stand 1 minute to soften. Gently heat over low heat, stirring, until gelatin dissolves and is clear. Add white chocolate; stir until melted and mixture is smooth. Stir mixture into heavy cream in a medium bowl; chill 15 minutes. Beat with a handheld mixer on high until stiff peaks form. Transfer filling to a pastry bag fitted with a 1/2-inch plain tip.
With a knife, slice cakes open from sides, as if to cut into 2 even layers but stopping three quarters of the way. Pipe some filling into the middle of each cake. Press cakes together; place on a wire rack set over a jelly-roll pan.
Put bittersweet chocolate in a small bowl. Bring cream and corn syrup to a boil in a 2-cup glass measure in the microwave. Pour over chocolate. Let stand 2 minutes; whisk until smooth. Spoon the glaze over cakes, letting excess run off into the jelly-roll pan. Refrigerate to set glaze.
Decoration: Put white chocolate into a 1-quart resealable food-storage bag; seal bag. Place bag in a bowl of very hot tap water. Let stand 5 minutes until melted. Snip off one corner of the bag; drizzle melted chocolate over top of cakes. Refrigerate to set.
