This guitar cake was a last minute request from a very close friend who had bought her daughter a guitar for her birthday and wanted a cake to match and so a challenge I couldn't resist. I'm new to cake decorating and this was my first carved cake.
I made a basic sponge cake mix and froze it. The next day after a little defrosting I was able to slice and fill with buttercream before carving using a paper template I had prepared previously. I covered the whole thing in buttercream and chilled whilst I prepared the fondant I would need. When chilled I covered the body of the guitar with a light brown (Sugarflair autumn leaf colouring) then covered the neck of the guitar with black ready made fondant (I always use ready made black as I find it difficult to get pure black when mixing myself). I measured the depth of the cake and cut 2 long strips of fondant out of a dark brown fondant (sugarflair - chestnut). I rolled these up to help make it easier to apply them to the edge of the cake. A little water around the edges of the cake made it easier for this to stick.
Now for the fun bit. I used royal icing to add the struts of the guitar and used the gold wire I usually use for adding shooting stars or butterflies to cakes as makeshift strings. Other details I had previously made out of sugarpaste. Final details were added on using a fine paintbrush and sugarflair colours.
The cake was as like as the bought one as I could do. My friend was really chuffed - I hope you like it too.
I did this Guitar Birthday Cake for my daughter's 10th birthday. I looked around for templates and found one on the internet which I enlarged and cut out. Then I carved the cake and assembled it. (I started with a 1/2 sheet cake made with two store-bought cake mixes and iced with buttercream icing.)
I iced the guitar body in white and freehanded the inside border, also in white. Then I used the spray food coloring in blue and sprayed the outer part of the cake, giving an airbrushed look. Then I used a gum drop which I had sliced thinly as the buttons.
The tuning buttons on the top of the guitar are marshmallows and the strings are licorice. If I ever do another guitar cake, I am going to look around ahead of time for the pull-apart licorice that comes in black.
Since it was Easter time, I could find the multi-colored licorice but only in the little snack size. So I rolled several out to be thinner snakes and pressed them together to form one long string. However, if you do this, they will eventually shrink and break apart. I do not recommend this. Instead, it would be better to use the larger licorice, even if you can only find it in red. That was the case with me and I didn't want red because it wouldn't match the cake, but in hindsight, it would have been better to have red in one piece than the color I wanted in several pieces.
