This was my first time making a Grand Piano Cake! I have played the piano for 34 years. When I found a vintage Wilton piano cake set on Etsy, I purchased it. But I didn’t make the cake for several years. I was too busy making birthday cakes for my family! And then, my daughter said she would like a piano cake for her birthday! I was so excited…. : ).

My Plan

  • Use Wilton grand piano cake pans or cut cakes to same shape.

  • Make chocolate keyboard in advance. First add dark chocolate to mold, then white chocolate. Make two keyboards.

Make the bench using a chocolate mold.

Assemble the bench and “glue” it together with melted white chocolate.

Make frosting flowers ahead of time (more details at the end of this post). It’s okay if they harden a little. Set them aside until ready to use.

Squeeze pink colored chocolate over wax paper in the shape of the music holder. It helps to have a plastic or printed music holder under the wax paper to trace!

Grand piano cake… finished! It’s actually easier than you might expect! If you have 3 pillars to use for the legs, use them. If you don’t– you could make the cake another layer higher so the bench looks right.
