Almond Cake with White Chocolate Cream Cheese Frosting, Ganache Filling and Praline and Chocolate Bark Decoration (Whew!)
Place chocolate in top of double boiler set over barely simmering water. Stir just until chocolate is melted, smooth, and just warm (do not overheat); remove from over water. Using electric mixer, beat cream cheese in large bowl until fluffy. Beat in 1 1/4 cups sugar, then warm chocolate. Beat 2 cups cream and 1 1/4 cups sugar in medium bowl until medium-firm peaks form. Fold into cream cheese mixture in 3 additions. Cover; chill. Refrigerate frosting at least 1 day and up to 4 days.
Whisk flour, baking powder, and salt in bowl. Using heavy-duty mixer, blend brown sugar and butter in large bowl. Beat in almond paste 1 piece at a time, then beat until smooth. Add eggs 1 at a time, beating well after each addition. Beat in extracts. Fold in dry ingredients. Divide batter among pans; smooth tops. Bake cakes until tester inserted into centers comes out clean, about 25 minutes. Cool cakes in pans on rack.
Line baking sheet with foil. Stir sugar and 1/4 cup water in heavy medium saucepan over medium-low heat until sugar dissolves. Increase heat; boil without stirring until deep amber, swirling pan and brushing down sides with wet pastry brush occasionally. Mix in nuts. Pour onto foil; cool. Peel foil off praline. Chop praline coarsely (you will want some smaller bits for the chocolate bark and between the cake layers).
Line baking sheet with foil. Melt chocolate in small bowl set over saucepan of simmering water. Stir until smooth. Remove from over water. Drizzle all but 1 tablespoon chocolate over foil in thick (about 1-inch-wide) zigzag lines (chocolate will pool in spots). Sprinkle 3 tablespoons praline over chocolate; chill bark until firm, about 1 hour.
Run knife around pan sides to loosen cakes. Turn cakes out; peel off paper. Place 1 cake layer on platter. Spread half of ganache over; sprinkle with 1/4 cup praline. Top with second cake layer. Spread remaining ganache over; sprinkle with 1/4 cup praline. Top with third cake layer. Spread frosting over top and sides of cake in 2 layers. The first layer is a light layer (the crumb coat). The second layer should be heavier and smooth. Chill the cake between the layers.
Press praline around bottom 2 inches of cake; sprinkle more atop. Peel foil off bark; break into pieces. Press edges into frosting atop cake. Remelt 1 tablespoon chocolate over simmering water, stirring often. Using spoon, drizzle chocolate over cake.
