I'm not really a cake decorater at all, but i do like to dabble in fun baking. I mostly stick to simple, easy things and leave the beautiful creations to the experts!

As always, the recipe is just a guideline, if your cake recipe is better, or if you're just more comfortable with it, use that! This is just a guide on the basic idea.

[the pictures in here are brought in from several different 'batches' of cake making - in case you spot any inconsistencies! i kept forgetting to photograph a step!]

So. Rainbow cayke!

I’ve made this in normal versions and in a vegan version and it works pretty well in both. It’s based on the normal sponge-cake recipe. As well as the normal cake ingredients you will need red, blue and yellow food colourings [green and black are optional, as are related flavourings: make the orange slice taste orangey, the yellow slice taste lemony etc.] and perhaps some jam to bind the slices.

Normal Recipe:
200g self-raising flour [or plain flour with bicarbonate of soda]
200g sugar
200g butter
4 eggs
2 tsp vanilla [or whatever flavour you want]

Cream the flour and sugar.
Beat in the eggs and add the vanilla.
Slowly fold in the flour. Use flour or milk to adjust consistency.
Bake at 180 degrees C for 10 - 15 minutes or until done!

Vegan Recipe:
250g of self raising flour
1 teaspoon of bicarbonate of soda [don't forget it! self-raising flour doesn't have enough really]
150g of sugar
200ml of sunflower oil, or vegetable oil, or corn oil... you get the idea.
200-300ml of Soya milk [roughly, you need to add it slowly until you've reached the right consistency]
2 teaspoons of vanilla essence or extract [for flavour]
Pinch of salt.

Put sugar and oil and half the milk and the vanilla together and mix.
Mix the flour, bicarb and salt and slowly add, beating in well to get rid of any lumps.
Adjust with flour or milk to get the right consistency.
Bake at 150 degrees C for 15 - 25 minutes or until done!

Okay. So now you can make a basic sponge cake mixture.

But to make rainbow cake you need to make six or seven or them, each with a different colour. Use about four generous teaspoons of colouring in the mixture. You want the colour fairly strong. Mix them just like paints, so get orange by mixing red and yellow; green can be bought on its own or made from yellow and blue; purple is blue and red, indigo is blue and black - yes, you can get black food colouring!

So add your colourings and mix it in, this is the orange one:

Then bake in a SWISS ROLL TIN or flat baking tin. I’ve also made a round version of this by baking a small amount in a round sandwich tin, but rectangles are easier later. This is the red layer:

Repeat this with all the other colours until you end up with six or seven cakes all lined up:

Let them cool and then start layering them, using warm jam or butter icing to bind them:

Until you have a huge stack of cake!

Now trim the edges:

And cut the entire thing into three or four slices. Put each slice on its end so the layers run vertically [yes, you'll end up with three or four separate cakes, but if you wrap them up in a double layer of cling film they freeze wonderfully to be used later]

As you can see, I’d started to ice that one. The icing is basic butter icing [butter/margarine and icing sugar, with a bit of vanilla to flavour. if you use vegetable-oil-based margarine the icing will be vegan too.]
This cake has coloured icing, but it also works wonderfully with plain or solid-colour icing. You bring out a plain cake, and then cut it open to reveal the rainbow inside!
It’s easiest to make one big batch of icing, and then separate it into six or seven bowls to add the colours. Remember that you'll need much more of the end colours than the others!

Then use a piping bag [or a freezer bag with the corner snipped!] to ice the colour onto the cake, it's a bit tricky not to mix the colours! I recommend starting with the middle colours and working outwards.

And there you go! Rainbow cake!

hope that's okay! *waves to comm*
