Everyone will be impressed with this luscious fruit-filled four-layer dessert. The filling in the recipe combines cranberries, orange peel, lemon juice, and spices, making a striking Christmas presentation.
In a medium saucepan, combine cranberries, the 1-1/4 cups granulated sugar, the cranberry juice, orange peel, lemon juice, cinnamon, ginger, and cloves. Bring to boiling; reduce heat. Simmer, uncovered, about 10 minutes or until thickened. Transfer filling to a medium bowl. Cover and chill for 2 hours. Transfer to a blender or food processor. Cover and blend or process until smooth.
Meanwhile, preheat oven to 350 degrees F. Grease the bottoms of two 9x1 1/2-inch round cake pans. Line bottoms of pans with waxed paper; grease and lightly flour pans. Set aside.
In a medium saucepan, cook and stir the 8 ounces white chocolate over low heat until melted. In a medium bowl, combine flour, baking powder, and salt. Set aside. In a large bowl, beat the 10 tablespoons butter with an electric mixer on medium to high speed for 30 seconds. Gradually add the 1-1/3 cups granulated sugar, beating until combined. Add eggs one at a time, beating after each addition. Beat in the 1-1/2 teaspoons vanilla. Alternately add flour mixture and milk to butter mixture, beating on low speed after each addition just until combined. Beat in melted white chocolate just until combined. Spread batter in the prepared cake pans.
Bake about 30 minutes or until a toothpick inserted in the centers comes out clean. Cool cake layers in pans on wire racks for 10 minutes. Remove layers from pans. Peel off waxed paper. Cool completely on wire racks.

Top with the second layer; spread with one-third of the filling. Top with the third layer; spread with the remaining filling. Top with the fourth layer, cut side down.
