Is a rainbow cake normally covered in fondant or buttercream ?

I don't think there is a normal. It's up to the chef to decide what they want to do and the flavors that will go with it. Either would work well, you just have to decide how you want the look of the cake to be on the outside. I once made a neapolitan cake but frosted it with a vanilla buttercream. It looked kind of plain, but was very cool when it was cut. With the cake you are making I think the the awesomeness will be once it cut.

The nicest one that I have had was from Harrods, and was covered in cream cheese frosting My mouth is watering just thinking about it!!

Sounds absolutely yummy. Was it a slice or whole and may I ask how much it cost?

I bought it by the slice, £4..95 - but its a huge slice and has 5 layers They sold it as a whole cake too, think it was £44, which isn't too steep for Harrods!
Everytime we go down I buy a few slices, it takes two of us to finish one!

Thank you. I couldn't find it on their website. I will definitely go for a slice of rainbow cake.

OT, other than the appearance, what distinguishes a rainbow cake from a red velvet cake? Perhaps the thickness of each layer?

It isn't on their website, just available in the food hall

A rainbow cake has several thin layers of differently coloured sponge and looks like an ordinary cake from the outside. When it is cut, all the different layers are revealed.

So a red velvet cake becomes a rainbow cake if you use a different colour for each layer of cake?

Yes, pretty much.

I have seen so many demos on how to make various types of rainbow cake, but have yet to make one. I love the one with many thin individual layers of colours, but I think I will attempt the one with two 8 ins sandwiched together, with circles of colour (the easy method).

Please show your final cake and with a slice taken out, Andy, I would love to see it.

Oh, and to answer the question…personally I would prefer a buttercream covered cake, but I appreciate the fondant cover will look cleaner and neater and more flawless.

What does the OP do with all his cakes ? surely he doesn't eat them

OMG..I want some of that http://www.bbcgoodfood.com/recipes/3028705/rainbow-cake

No, I don't eat them all myself
I teach Karate twice a week. If I make a lot of cupcakes, I give a box of six to my friend who gives me a lift to Karate, and I take a box of 12 to the Karate club - hopefully to get orders for cupcakes / cakes, but I've had no orders ( ), so I'm thinking of not taking any more into the club.

Andy, may I ask which of your cakes would you say are your best creations?

awww that's nice you could just make them and take them in, spoil yourselves

i have a habit lately of buying biscuits for work, and taking them in ..they do go quick, and i always hope there some left for when i go in next day

I don't really know, I love them all !
