Piano Cake.

White and dark chocolate bars are “key” to decorating this piano cake baked from an easy mix.


Piano Cake


  • 1 box cake mix (any flavor*)
  • Water, vegetable oil and eggs called for on cake mix box
  • Tray or cardboard (15×12 inches), covered with wrapping paper and plastic food wrap or foil
  • 2 bars (3.5 oz each) white chocolate candy
  • 1 bar (1.55 oz) milk chocolate candy
  • 1 1/2 containers Rich & Creamy chocolate frosting


  1. Heat oven to 350Β°F (325Β°F for dark or nonstick pan). Make cake as directed on box for 13×9-inch pan. Cool 10 minutes. Run knife around sides of pan to loosen cake; remove from pan to cooling rack. Cool completely, about 1 hour. For easier handling, refrigerate or freeze cake 30 to 60 minutes or until firm.
  2. Use serrated knife to cut cake as shown in diagram (for piano bench, cut 4 1/2×1 1/2-inch piece; cut horizontally in half to make bench lower than piano, if desired). Place cake on tray. Place about 2 tablespoons frosting in small resealable food-storage plastic bag. Frost cake with thin layer of frosting to set crumbs. Refrigerate or freeze 30 to 60 minutes to set frosting. Frost entire cake.
  3. Cut 1 bar white chocolate into 1 3/4×1/2-inch strips. From remaining bar, cut 2 1/2×1 1/2-inch piece for music. Cut milk chocolate into 1×3/8-inch pieces. Place white and milk chocolate pieces on cake for piano keys. Cut off tiny corner of bag with frosting; pipe frosting notes on white chocolate “music.” Place above keys. Store loosely covered.
