Anyone made rainbow cake?

[zenie]

I want to make a cake like this....

But I keep finding recipes using a packet (spit) mix

 

[sheothebudworths]

Couldn't you just do a normal mix, split the batter up into as many bowls as you wanted colours, add food colouring then when they're mixed in, put the individually coloured blobs of batter into the tin next to each other? That's what it seems has been done up there?

 

[zenie]

Yes I've realised that now

I need to do a disco cake so am thinking this might be a good idea for it?

 

[sheothebudworths]

I was a bit confused by your confusion, tbf imagining you going 'OMG! How the FUCK did they do THAT?!? ' 'Errrrrrrrrrr....zenie..... '

PERFECT for a disco cake, YEAH! You could get some of those silver ball things to stick on top too (y'know the ones that feel like they'll break your teeth )?

 

[sheothebudworths]

Or they do all that edible glitter business now, too (not cheap though).

 

[boohoo]

Aqua did a similar cake but with horizontal stripes. So you make separate layers in different colours and then glue together with icing.

NB: I haven't made on like that, but this is how I'd attempt it.
First get your food colouring - red, yellow and blue (green is optional because it can be mixed), a large mixing bowl, your cake tin (or 2 sandwich tins), your favourite plain cake recipe (victoria sponge?), and 7 small bowls.
Preheat the oven and prepare your cake tin as your prefer (lined/greased/greased and floured).
Mix your plain cake recipe and divide it as evenly as you can between the 7 bowls. The mixture in these will be coloured and then added to the tin(s), beginning with the red and working inwards (I think) with as little swirling as possible:
Colouring more or less as follows (increase as required):
2 parts red
1 red, 1 yellow
2 yellow
1 yellow, 1 blue
2 blue
3 blue (indigo should be darker than blue)
1 red 1 blue
Bake as usual. If it comes out wrong, turn it into a trifle or cover with custard.

Search for rainbow cake images on Pinterest. You will see some of the most beautiful pictures of your LIFE. Oh yes.

Or maybe I just like cake too much. But, hello.

Do you get tinkly shits?

 

[sheothebudworths]

I don't know....it was too pricey for me to justify buying it when I saw it

 

[Dooby]

These are sooo beautiful *goes into happy trance*

 

[kittyP]

They are fucking brilliant!

Or if you're feeling particularly adventurous - try this "Mid-night"cake

Black as night and crunchy as tar

 

[bi0boy]

Someone should make a rainbow UV fluorescent cake.

 

[nagapie]

I'm pretty sure aqua's made something that type of fancy.

get colouringz with e numbers in them, the ones that they sell as natural colourings can break down in heat

If the cake's being made to share and you use chemical colouring FFS make sure that it's clearly labelled and (if poss) that it's not going to exclude anyone. At least make sure there'll be other equally appealing options. Being unable to share the cake (or other food) with everyone else can be deeply unpleasant.

if zenie wants a coloured cake, it needs to be done with chemical colours.

People don't actually make those ^^^^ cakes for eating? Do they?

What do you think? Put enough icing on it and somebody's going to want to eat it. FWIW food colouring concentrates used by professional cake decorators produce very strong shades indeed (proper scarlet instead of washed out dark pink).

If you only had a small helping and don't have an allergy (or other health problem) triggered by those colourings, you'd be fine.

I was hoping for a layered cake - sponge with cream and fruits of the various colours. One layer each of Strawberries, Oranges, Pineapples, Kiwi Fruit or Grapes, Blueberries, Blackcurrants, and Mulberries, all with cream.

And chocolate on top.

 

[red rose]

I've made rainbow cake and I recommend the gel colouring, it stays bright when cooked.

I just made regular cake batter, split it into six bowls and mixed in the colourings.

This was mine, it looks a little wonky because I'm really not a very good cook but it did the job.

 

[Looby]

Aqua definitely made one too, think it was for pickles birthday.

Those swirly ones look amazing but I know I'd completely cock it up. : D

 

[Callie]

I have a friend (well several actually!) that bakes crazy cakes and she has said you have to use the gel/paste colourings rather than plain old food colouring as the colour comes out better and brighter after baking.

A few rainbow cakes I have seen seem to be quite tall affairs like red roses.

 

[zenie]

Ooh thanks for the replies...I had seen the layered one on here but they produce a really tall cake, and are more hassle having to ice between the layers ( lazy ) if I was doing a massive cake and had huge sandwich tins it'd be alright though, as it wouldn't look so tall.

I think I'll do a tester with the Dr Oetker colourings I have, otherwise I'll get some gels. The red works fine for red velvet, though I guess the cocoa in the recipe might help tint it too

 

[zoooo]

Holy shit.

 

[aqua]

Holy shit.

that's superb

yes I made one like red rose for pickles first birthday - it's really not hard to do neither is one where it's one layer all smooshed together

I made chocolate and banana cake once (similar idea). You'd think the layers would run into each other but they don't really. It was freaking delicious.
