Step 1:Position rack in center of oven and preheat to 350°F. Butter three 8-inch-diameter nonstick cake pans with 1 1/2-inch-high sides. Place devil\’s food cake mix, 1 cup water, 1/3 cup vegetable oil, eggs, vanilla extract and 1/4 cup sour cream in large bowl. Using electric mixer, beat batter 2 minutes. Stir in 1 cup semisweet chocolate chips.

Step 2:Divide batter among prepared pans (about 1 3/4 cups batter for each). Bake until tester inserted into center of cake layers comes out clean, about 25 minutes. Cool cake layers in pans on racks 15 minutes. Run small sharp knife between pan sides and cake layers to loosen. Turn out onto racks; cool completely. Bring 1/2 cup raspberry jam and 3 tablespoons unsalted butter to simmer in heavy large saucepan over medium heat, stirring often. Remove from heat. Add remaining 3 cups semisweet chocolate chips and stir until melted. Add remaining 3/4 cup sour cream and 2 cups powdered sugar. Using electric mixer, beat frosting in pan until smooth and thick, about 2 minutes.

Step 3:Place 1 cake layer on platter. Spread 3/4 cup frosting over. Top with second cake layer. Spread 3/4 cup frosting over. Top with third cake layer. Chill cake until frosting sets slightly, about 15 minutes. Spread remaining frosting in swirls over top and sides of cake. (Can be prepared 1 day ahead. Cover with cake dome and let stand at room temperature.)

Step 1:(CRUST) Butter the sides only (not the bottom) of a 9-inch spring-form pan (2 1/2-3 inches deep). Grind the Amaretti very fine in a food processor or blender. Mix with sugar in a mixing bowl. Melt the chocolate and butter in the top of a double boiler, stirring occasionally. Add the melted mixture to the Amaretti crumbs and sugar and mix thoroughly. (Don’t wash the double boiler; you’ll be using it again in a minute.) Turn the mixture into the prepared pan. With your fingers, distribute it evenly over the bottom and press it down into a very firm, compact layer. Refrigerate while you prepare the filling.

Step 2:(FILLING) Adjust rack 1/3 up from the bottom of the oven and preheat to 350 deg. F. Partially melt chocolate in the top of a double boiler, then uncover and stir until completely melted. Remove the top of the double boiler and set aside to cool. Break the Amaretti coarsely into a bowl and set aside. Cut the almond paste into small pieces, and beat on low speed with an electric mixer, while gradually adding the Amaretto liqueur. Beat until thoroughly mixed, and set aside.

Step 3:the cream cheese with an electric mixer until smooth. Add the sugar and beat until smooth again. Add the almond paste-Amaretto mixture and beat until thoroughly mixed. Add the melted chocolate and beat well again. Add the eggs one at a time, beating at low speed until they are incorporated after each addition. Add the heavy cream and beat until smooth. Add the coarsely broken Amaretti and stir gently only to mix. Turn into the prepared pan, pouring the mixture over the bottom crust. Rotate the pan gently to level the batter. (Don’t worry if the mixture comes almost to the top; it won’t run over.) Bake 45 minutes. It will seem soft and not done, but don’t bake any more; it will become firm when chilled.

Step 4:NOTES Amaretti are Italian almond-flavored wafer cookies. They are usually sold in metal tins with the wafers wrapped in packages of two inside the tin. You can also buy Amarettini, which are the same flavor but much smaller and not individually wrapped. Since you’re going to grind some of the wafers and break the others into chunks, it doesn’t matter which size you start with.
