How to Make It
Preheat oven to 350°. Prepare Ginger Whipped Cream as directed in Step 1 of recipe (through chilling).
Microwave chocolate morsels in a microwave-safe bowl at high 1 to 1 1/2 minutes or until melted and smooth, stirring at 30-second intervals.
Beat brown sugar and butter at medium speed with an electric mixer until well blended (about 5 minutes). Add eggs, 1 at a time, beating just until blended after each addition. Add melted chocolate, beating just until blended.
Sift together flour and next 5 ingredients. Gradually add to chocolate mixture alternately with sour cream, beginning and ending with flour mixture. Beat at low speed just until blended after each addition. Stir together hot water and next 2 ingredients. (Mixture will foam.) Gradually stir molasses mixture and vanilla into chocolate mixture just until blended. Spoon batter into 3 greased and floured 8-inch round cake pans.
Bake at 350° for 25 to 30 minutes or until a wooden pick inserted in center comes out clean. Cool in pans on wire racks 10 minutes; remove from pans to wire racks, and cool completely (about 1 hour).
Meanwhile, prepare Silky Ganache. Place 1 cake layer on a cake stand or serving plate. Spread with half of ganache; sprinkle with 1/2 cup toffee bits. Top with second cake layer; spread with remaining ganache, and sprinkle with remaining 1/2 cup toffee bits. Top with remaining cake layer. Cover and chill 2 to 8 hours.
Finish preparing Ginger Whipped Cream as directed in Step 2 of recipe. Spread top and sides of cake with whipped cream just before serving. Garnish, if desired.
The addition of hot water at the end of this recipe makes for an exceptionally moist cake.
