1.Preheat the oven to 180 C or 356 F.

2.Line your rectangular or guitar cake tin with baking paper, then grease with butter over the top. This will stop your cake from sticking to the tray when you remove it from the oven.

3.Add the caster sugar and butter into the large bowl and beat together with the wooden spoon until it forms a soft mixture, and the butter has melted. Alternatively, this can be achieved quickly by using an electric mixer.

4.Add the eggs, flour and baking powder into the bowl and mix well until you have a smooth but fairly thick mixture, with no lumps.

5.Carefully pour the mixture into your cake tin and smooth with a spatula if uneven.

6.Bake your cake in the oven for about 45 minutes, until it is golden brown on the outside and light and fluffy on the inside.

7.Make a large quantity of vanilla or chocolate butter icing. You can make the buttercream chocolate flavoured by adding cocoa powder to the mix, and skipping the juice.

8.Leave your cake to cool in the tray for about 15 minutes, then move it to the cooling rack, and leave for about 25 minutes. Then place on a cake board.

9.If using a guitar tin, skip step 9. If using a paper template, place it on the cake and use a knife to carve your cake into a guitar shape.

Don't worry if your template is too long for your cake; simply leave one long edge of the cake to fashion the guitar's neck, and stick it on with some butter icing or jam later on.

10. Slice the cake in half, so there is a top and a bottom layer.

You could use a cake knife, or even some floss for this step, for a particularly sharp finish. Spread your butter cream liberally in the middle of the cake, then carefully place the top layer back on top. Ice the sides and top of the cake too.

Alternative: You could always leave the butter icing as the final icing on your cake, and start the decorating process from this step, if you don't fancy fondant icing.

11.Sprinkle flour on your surface then roll out your fondant sheets. Place the first fondant sheer over the guitar's main section, then gently press it down from the middle of the cake to the edges for a clean, sleek finish.

Use a spatula to remove any excess fondant at the edges. Repeat this step for the guitar's head and neck.

12.Once your guitar birthday cake is covered in fondant, its time to decorate! You could draw on the guitar's details using shop-bought tube icing, or design it using fondant shapes. This is a great simple method for beginners, or for younger kids who want to help with the baking:

a) Acoustic Guitar Cake:

You could ice around the edges of the cake using a shop-bought tube of icing and use a jam jar lid to create the outline of the sound hole and then fill it in.

You could use white icing to pipe horizontal lines across the guitar's neck, for the frets and then vertical lines for the strings. More experienced cake makers could also cut out the different parts of the guitar's face using any remaining fondant icing, and a printed out template.

For fondant strings, simply roll out some long, thin pieces of white fondant and press gently down the guitar's neck.

b) Electric Guitar Cake:

You can use icing in a tube or fondant cut to the shape of a template to decorate electric guitar cakes, too. Fondant icing works especially well.

For especially experienced bakers you could use silver thread for the strings, attaching each string to a toothpick on both sides and pressing down into the cake. The face, frets and pickups are fairly simple to make, though - just roll your fondant into whichever shape you need, based on a template or diagram of an electric guitar.

Top Tip: Chocolate chips or silver dragées are great decoration ideas for the tuning keys! Just line up three on each side of the top of the guitar's head.

c) Pop-Star Guitar Cake:

Why not add an extra special touch to your child's birthday cake by including their favourite pop star or band? For younger kids you could buy or use some dolls you already have and style them so they look like the singer or band.

Stand them up on the cake using icing to stick them down, or have them sitting on the edge of the cake.

You could also use fondant or piped icing to recreate a band logo, which is a great option for kids of all ages. This will make for an especially cool addition to your cake.

Extra Tips And Information

If you want a chocolate flavoured cake, simply add 8 teaspoons of hot chocolate powder and 8 teaspoons of cocoa to the mix.

This cake will keep for 5 days in an airtight container. If you want to get ahead of the game, you can freeze it for up to 3 months.

Kids of all ages can help make this yummy cake, although some of the more complex parts of the decoration such as making the guitar's strings out of thread are best left to adults and children over the age of 10.

Children of any age can eat the cake, although silver dragées should not be given to children below the age of 10.
