My son wanted a car for his 16th birthday. He also wanted a guitar. I was cheap so he got the guitar. He also got a matching cake to go with it. This cake is modeled after the Kona KES1 Series Double Cutaway Red Electric Guitar. Of course, you can make any kind of guitar cake you want, but the instructions are written for this cake - exactly as you see it pictured here.

I’ve been making birthday cakes for my family for years. I search online for inspiration, tips, and (because I can be quite lazy at times) shortcuts are always welcome. I am definitely an amateur but I enjoy decorating cakes and want to show people that they too can make beautiful cakes with just a few materials and some patience.

This was my first time creating a cake with fondant. I had previously avoided fondant like the plague but I knew this cake would look so much better with fondant.

To avoid the bland, undesirable taste of store-bought fondant, I decided to try making marshmallow fondant. I could make it fairly quickly and flavor it as I wished. I used a great recipe that can be found at What's Cooking America. It turned out beautifully and I have been using the same recipe ever since.

This cake looks big - especially stretched across a board 2  feet long, but it is made from a modest 9" x 13" cake so you can bake the cake right at home and shouldn't have to worry about too many leftovers.

Step 1: Materials and Template

To make this cake, I first had to create the template. I traced a guitar. It took 4 sheets of 8x11 paper. I scanned the tracings, put them together and shrunk the body of the guitar to fit on one 8x11 sheet of paper.

I also traced the head of the guitar and shrunk it down to be (somewhat) proportional to the base. Both the head and the body templates I used are attached below. You'll need to print them both and cut them out before placing them on your cake and carving.


1 baked and cooled 9x13 cake
Guitar template (you can get it below)
Small Knife
Pizza Cutter
Dental Floss (optional)
1 container icing (any flavor) – I used vanilla just in case some icing just in case I had any icing to show through the fondant on the finished cake. It didn’t.
Spatula – for icing the cake
1 full batch of marshmallow fondant – (recipe from What's Cooking America) I did not color the fondant but I did flavor it with almond flavoring. You could use purchased fondant instead of making it. I would guess you would need to buy a couple pounds to be on the safe side – It can be white. The cake is painted later.
Rolling Pin

Large Cake Board - the one you see pictured is a 14" x 21" silver colored cardboard cake board that usually costs under $3 at a party store or craft store. *
Red food coloring gel - I used Wilton’s no-taste red gel
Black food coloring gel
Almond or clear vanilla flavoring - don’t use regular vanilla unless you are making a brown or black guitar. The brown in the vanilla will discolor your colors
Wilton Silver "Pearl Dust"
Wilton Gold "Pearl Dust"
(optional) - just a small amount of this was used to paint text on the headstock of the guitar
3 Small Paint Brushes (or you could just use the same one over and over)
3 Small Bowls – for mixing your “paint”
Silver Dragees - these little silver balls can be really hard to find nowdays. It might be best to get them somewhere online.
Metallic Silver Embroidery Floss - this is for the "strings".  I tried wire. It didn't work.
Toothpicks - lots

*If you don't want to buy a large cake board, you could cover a large sheet of wrapping paper (front and back) with clear contact paper. It's washable and easily rolled up for storing. AND you can match it to any birthday party. If you ever need to move your cake while using this method, slide a large flat baking sheet under the paper and lift your cake.

Im cheap too lol. That and I've noticed when trying to add color to fondant I always get a marbeling effect, which doesnt work unless you're wanting camo lol. How did you make the gold bridge? And Thank you so very much for getting back to me so quickly.
It's just a fat fondant rectangle with strips of fondant across the top. Then I used a dab of water to &quot;glue&quot; them all together. It was &quot;painted&quot; and dried before being placed on the cake (because it actually went on top of the strings).<br><br>I used Wilton Pearl Dust to paint it along with all the other metallic looking parts. You need to add quite a bit of the pearl dust to just a few drops of water/alcohol/extract but a little goes a long way. If the mixture is too thin, the metallic color won't show.<br><br>I've also tried using the Pearl Dust dry but it was VERY faint. You couldn't even tell any had been applied. I opt to paint it on every time.
I am making an electric guitar cake for Friday. I love your easy to follow instructions. I have some questions though. All I own is gel colors...would I still paint the same way? <br> <br>And...I have used MMF for years now. I Love it for decorations, but I cant stand it when having to cover a cake. I go to roll it out and it always seems to be &quot;too&quot; elastic, if that makes sense. Just when I think I have the right size, its like it retracts a bit. It seems to be more like modeling clay then fondant. Plus I have found, also that if I dont sift my powdered sugar, I tend to have little sugar balls everywhere. So not pretty. What am I doing wrong? Please help me. Totally frustrated! And i just figured I would ask an expert ;)
Oh, I am NOT an expert. I found that I always have to sift my sugar and the longer I knead, the more pliable the fondant. Humidity also changes the results. If you still have trouble, ice the cake instead and make the rest out of fondant.<br><br>The gel colors will be fine for painting (that's what I use - concentrated gel). I just prefer to paint on colors because I get a brighter color and I can be sure I have enough fondant to cover everything. I'm so cheap, I don't want to make too much of one color and not enough of another.
Wow, this is beautiful! You have amazing attention to detail. <br />I wouldn't want to damage the decoration with candles either, much less eat it. :)
Thank you! We had no problem eating it :)
One of the awesomest cakes I've ever seen ! <br>You got my vote + 5 star rating !
Wow! Thank you so much!
That is an amazing cake! I'm not really a guitarist, but I would still love to have/eat this cake!
Thanks! I leave the guitar playing to other people, but I definitely partake in the guitar cake eating :)
Well done!!
Love that High-Five! Thank you!
Cars rust. They are temporary. The music will last a lifetime. You are an awesome mom!
Awww...Thanks! He was actually quite pleased when his friends thought he had the &quot;coolest birthday cake ever&quot; and then started jamming on their guitars :)
Great job!
Thank you!
omg! it reminds me of the one i saw at michaels! :D but you did a really cool spin on it! :D http://www.michaels.com/Duff-Guitar-Cake-Kit/bk0737,default,pd.html
Wow, is that from a cake pan? It sure would have come in handy. The only cake mold I had seen before was the Wilton acoustic guitar pan and that one was just NOT going to work
lol! no, i believe it came with templates. they just clearanced them out, too. :)
Wow, what a stunning cake. Clearly you put a lot of time and thought into each aspect of the cake's design. Very clear and detailed instructions, too. You certainly have my vote for the cake decorating contest!
Thank you! It took a lot of time but was well worth it. I certainly appreciate your vote!
