White Chocolate Cake with Orange Filling

White Chocolate Layer Cake with Orange Filling by Chef Vincent Troeppe

By Chef Vincent Tropepe

  • 2 1/4 cups all-purpose flour 
  • 2 1/2 teaspoons baking powder 
  • 1/4 teaspoon salt 
  • 1 1/2 sticks (6 ounces) unsalted butter, softened 
  • 1 1/2 cups sugar 
  • 4 large eggs 
  • 1 teaspoon pure vanilla extract 
  • 1 1/4 cups milk 
  • 8 ounces white chocolate, melted 
  • 2 tablespoons orange marmalade, very finely chopped if chunky 
  • 1/4 cup confectioners’ sugar 
  • White Chocolate Buttercream (recipe below)
  • 1/2 cup Candied Orange Peel, dipped in white chocolate, for garnish (optional) 


  • Step 1 Preheat the oven to 350°. Butter and flour two 9-inch round cake pans.
  • Step 2 Sift the flour with the baking powder and salt. In a large bowl, using an electric mixer, beat the butter at low speed until smooth. Add the sugar and beat until fluffy. Add the eggs, 1 at a time, beating well after each addition. Add the vanilla. At low speed, alternately beat in the dry ingredients and the milk in 2 additions. Add the melted white chocolate and beat just until incorporated. Scrape the batter into the prepared cake pans and smooth the surfaces.
  • Step 3 Bake the cakes in the center of the oven for 35 minutes, or until golden brown and a toothpick inserted into the centers comes out clean. Let the cakes cool in the pans for 10 minutes, then invert them onto a wire rack and let cool completely.
  • Step 4 In a small bowl, using a handheld electric mixer, beat the orange marmalade and the confectioners’ sugar into 1 cup of the White Chocolate Buttercream. Set 1 cake layer on a cake plate, right side up, and spread the filling on top. Cover with the second cake layer. Frost the sides and top of the cake with the remaining White Chocolate Buttercream. Garnish with the white chocolate–dipped Candied Orange Peels and serve.

The frosted cake can be refrigerated for up to 2 days.

The filling for this cake calls for orange marmalade, but you can also use seedless raspberry, apricot jam or a high quality Italian pistachio creme.
