White and dark chocolate bars are "key" to decorating this piano cake baked from an easy mix.
Updated Oct 10, 2022

Ingredients

Steps

  • 1
    Heat oven to 350°F (325°F for dark or nonstick pan). Make cake as directed on box for 13x9-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. (See link below for diagram.) For piano bench, cut 4 1/2x1 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 3/4x1/2-inch strips. From remaining bar, cut 2 1/2x1 1/2-inch piece for music. Cut milk chocolate into 1x3/8-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.

Tips from the Betty Crocker Kitchens

  • tip 1
    *For all chocolate and devil's food cake mixes, use only 1 cup of the water.
  • tip 2
    To make it easier to cut chocolate bars, have chocolate at room temperature. Heat a sharp knife in hot water and dry before cutting chocolate.
  • tip 3
    Pick up an extra white chocolate candy bar in case one breaks.
  • tip 4
    Create an attractive display by covering a piece of sturdy cardboard with wrapping paper, then plastic food wrap. Stretch and secure with tape. Or cover cardboard with foil or cooking parchment paper.
