Due to the awesomeness of my rainbow cake, I've had a few people ask me how to make one. So, here's a step by step guide in making your own rainbow cake! This is a really fun and easy cake to make which will impress everyone, perfect for a birthday or special occasion.

This is actually the procedure to make just the bottom of the cake, so it's not a sandwich, but if you want to make it look exactly like my final cake, just double the ingrediants and do everything twice, with two cake tins.
The actual cake recipe I used was terrible. Here's the one I used, though, honestly any sponge cake recipe will work. I recommend using one that actually includes margarine, as this cake was chewy and not very tasty!
3 Eggs, beaten
100g Caster Sugar
100g Self Raising Flour
Red, blue and yellow Food Colouring
Betty Crocker Buttercream Style Icing, Vanilla flavour
Loads of Smarties
5 bowls and 5 tablespoons
A cake tin, about 25" wide, 2" deep
1. Preheat the oven to Gas Mark 5 / 190°C
2. Grease your cake tin
3. In a mixing bowl, mix the eggs and the caster sugar together until fluffy,
4. Fold in the flour, mix until it's soft and not lumpy
5. Seperate equal amounts the mixture into five bowls.
6. Stir in one tablespoon of red food colouring into one bowl, one tablespoon of blue into another, one tablespoon of yellow into a third bowl. You need to use seperate spoons each time or the colours will run!

7. Next, use half a tablespoon of blue and half a tablespoon of red into the fourth bowl to make purple. Red is quite a strong colour so you might want to use less red and more blue or it'll look like a very reddy purple. Do the same thing with blue and yellow in the fifth bowl. You might ask "What about orange?" but I found that, because the red was quite strong, it wasn't very orange at all and in fact looked exactly like the red! So I left out the orange. Now you should have five very colourful bowls!

8. Ok, now you've got your seperate colours, get your cake tin and pour in your first bowl. Make sure the mixture covers the entire bottom of the tin. You're going to pour in each colour into the very center of the bowl and it's going to spread right out! I probably should have made a video, but here's a few pictures to give you the idea:


Carry on until you use all of the bowls and you should have a colourful goo in your cake tin!

9. Pop your cake into the oven on the middle shelf for 20 minutes, or until the center of the cake is soft and cake-like when you push on it. Go do the washing up or something!
10. Take the cake out and leave it to cool on a wire rack. It should look something like this:

11. Skip this step unless you're making a sandwich cake. When the cake is cooled, smother buttercream all over the top of the bottom layer. Make sure you get the cream right up to the edge. Then put the top half of the cake on top of it.
12. When the cake is cooled, get the buttercream mix and smother every inch of the cake with it! You'll want to cover every part of this up, because it's gonna be a real suprise to everyone else when you cut into it to reveal it's awesome innards.
13. Add smarties to every possible area.
14. Leave to cool for a couple of hours in the fridge.
15 Serve and enjoy!

If you make your own rainbow cake, I'd love to see any photos of it! Or send me your variations!
My instant camera WORKS! I was contimplating not going all meta and taking a photo of the photo I took, but excitment got the better of me. I promise I won't take a photograph of every photo I take with it (unless it's a paticulary arty one) but oh gosh it works and it came out better than I thought it was going to. The film only has 8 shots, (which means I only have 7 left) so I have to think about what I'm going to take a photo of first, I'm mainly going to be taking a photo of friends really until I can think of more interesting things to take photos of. But, the most exciting part of all is, I get to cross a thing off my life list "Owning a polaroid instant camera" (I waited until now, in case the camera didn't work)
Now I need to go and take photos of awesome things all over the place!
