How to Make a Guitar Shaped Cake

Make Your Own Cake

A guitar shaped cake is a fun idea for a guitar or music themed party, a western party, or a Cinco de Mayo celebration! This article is about how to make your own guitar cake using a shaped cake pan and two methods of decorating: fondant or starring in with buttercream icing. I've also included pictures and videos showing how to achieve each method.

My grandson, Scott, wanted a guitar and music note themed 16th birthday party. So, his cousin had fun making him this awesome electric guitar cake.

Ashley used a Wilton guitar shaped pan (like the one below) to bake the cake. Since the pan is for an acoustic, she used a template for an electric guitar and cut out the design in fondant to lay on top of the cake. Keep reading for all of the details.

The Wilton shaped cake pans are of made of heavy aluminum so they heat evenly. Each pan includes instructions. You can alter this acoustic guitar to look like an electric. I've used the Wilton brand for years and they are the best when it comes to cake making supplies.


So Much Easier!

A shaped pan is much easier than baking sheet cakes and cutting out the design yourself.

Scott's cake was made with the Wilton guitar shaped pan. An electric guitar template was used to cut out the design in fondant. Isn't it awesome?

Decorating Methods

1. Fondant roll-out icing

2. Star-in with buttercream icing

Fondant Method

How to Use Fondant to Decorate a Guitar Shaped Cake

Ashley used fondant roll-out icing to decorate the guitar cake. If you're not familiar with fondant, it is a very smooth icing that is firm enough to roll out, much like pie crust dough. You can make your own fondant, but it's much easier to buy it already made, either in a ball or already rolled out. It's available in a variety of colors, or you can color it yourself if you want an unusual color. It's great for making decorations for cakes, and you can also cover the entire cake with fondant, rather than icing. Ashley iced her cake in buttercream, and used fondant for the decorations.

Step by Step Instructions:

  1. First, she iced the entire cake in white buttercream icing, getting it very smooth on the top and sides. (You can use whatever color you like, or use chocolate icing.) Note: You can also choose to cover the entire cake with fondant first, rather than icing. See the video below.
  2. She colored white fondant herself in the blue shade she wanted.
  3. She used a template of an electric guitar she found online to cut out the fondant for the blue top and lay that on the cake.
  4. Also using a template, she cut out the black sections (pick guard, fret board, knobs) of the guitar and placed those on the cake. She used fondant that was bought already colored for the black parts. To make the pieces stick, you need to wet the icing just a little bit with your spatula or fingertips.
  5. Added the frets and tuning keys using black icing and a round tip.
  6. Last of all, she rolled out the guitar strings using the black fondant and placed those on top. It was tricky getting them all straight. You might want to just use black icing and the round tip for this. In any case, it's probably the hardest part.

Note: These are directions for an electric guitar, but you can adapt them for an acoustic.

Watch the videos below if you're unsure how to use fondant to ice or decorate a cake.

You can find templates online for all types of guitars. Just do a search for: guitar templates for a cake.

Star-In Method

How to Use the Star-In Method with Buttercream Icing to Decorate a Guitar Cake

I've decorated many cakes, using different methods. For a shaped cake, I usually use the star-in method. It's very easy, even for the beginner. In some cases you can ice the sides of the cake with a spatula first and only use stars for the top of the cake. The guitar cake can be done that way, but for some designs it won't work. If you've never done this before, I suggest watching the video below to get the idea. Here's the quick version:

You will need:

  • Wilton decorating icing bags (disposable bags are fine)
  • Wilton #18 star tip (and coupler if needed)
  • Wilton #5 round tip
  • Spatula
  • Buttercream icing (You can make your own or buy it ready made.)
  • Food coloring to color the icing

Note: Wilton products can be purchased at your local craft store, Wal-Mart, or Amazon.

Note: Disposable icing bags do not need a coupler. Cut the end to fit the tip and put the tip directly in bag.

Directions for icing your cake:

  • Ice the whole cake in a thin layer of icing.
  • Color the icing you'll need for the cake.
  • If you only want to star in the top, go ahead and ice the sides with a spatula and smooth out.
  • Ice the headstock and fret board also. I recommend smoothing the icing on these parts rather than starring.
  • Draw on the sound hole and saddle (if acoustic)
  • Use the Star-in method to ice the cake using your #18 star tip.
  • Add the frets and guitar strings by using the #5 round tip in your decorating bag and white buttercream icing.

How to star-in:

  • Place the star tip on the end of your icing bag by using the coupler.
  • Fill your icing bag with a colored icing. Don't put in too much; about half full is good.
  • Look at the design on your cake and decide where you want to start. There will be indentations in your cake from the pan mold to show the design of the pick guard. The directions with your pan will show you which colors go where, or you can choose your own colors.
  • With the icing bag in an upright position and close to the cake, gently squeeze the bag and you will see a star appear! Stop squeezing and then make another star next to the first one, and then on and on until you have the area filled in with stars. Try to make all of the stars the same size.
  • Next, do the same thing with a different color until all of the areas are filled in. Your hand will get a little tired before you're finished.

I recommend watching the video below to see how to ice a cake using the star method.

This Wilton kit has everything you need to decorate, with 10 disposable icing bags and 10 basic metal tips. Tips include the #18 star tip and #5 round tip that you'll need for the guitar cake.


Stages of Starring-In a Guitar Cake

Below are the different stages of decorating using the star-in method. Starting with the cake just turned out the pan with no icing to a completely finished guitar cake.

Stage 1: No icing Stage 2: Sides, headstock, and fret board iced. Stage 3: Sound hole and saddle added. Stage 4: Cake is completely starred in and strings added.

This is another example of a guitar cake with smooth sides and star-in icing top. I like the different colors and black pick guard and fret board.

Video: How to Use the Star Tip

The video below shows you how easy it is to completely ice a cake using the star tip, and how to make a star border. Now you can make your own cakes and impress everyone! I've done this many times, and it's not hard at all. I know you can do it, too!

Which Method is the Easiest?

Fondant or Star-In?

I think the roll-out fondant method would be the easiest. Years ago the only method available for this type of cake was star-in, but these days with fondant already made and ready to use, it's the way to go. Also, I think it looks much nicer and realistic.


To summarize, this article shows how to make and decorate your own guitar cake. I gave instructions for using a guitar shaped pan and either using fondant or star-in buttercream icing to decorate it. I hope you'll have fun with your cake!

      My son would love a guitar shaped cake. Although he would probably love a guitar shaped ice-cream cake better!
