making a 2 year old birthday cake tomorrow, rainbow cake, can you help???

[030213babytime]

ive seen threads on here about the rainbow cake, it looks delicous so ive promised to make a cake for my nephews birthday, can you help me out?

its just basic sponge then food colouring for the colours, that looks easy enough, i just dont know how to put it all together.

what to i use to "glue" the sponges together?

what do i cover the cake in? i would like to decorate it and write happy 2nd birthday. what should i use? i dont have that much cake experiance.

i want the cake to both taste and look delicous, and the 2 year old has to like it too so no coffee/nuts.

thank you for your help :)

Join it all together with a buttercream (google for recipe), you could add flavours to this (lemon or vanilla?).

To ice the cake overall, you could use a buttercream also, or use buttercream plus the fondant style icing which you roll out this, and then add to cake which is covered in buttercream. Then decorate it.

Fondant is smooth. Buttecream will have more texture - look at google images for ideas.

Re the rainbow layers, you will not get strong colours using normal food colouring. The supermarket colours (liquid or gels) are just not intense enough to go beyond pastel colours. You will need to buy proper gel paste intense colours from cake suppliers or from amazon.

I have brought Dr Oetaka gel food colouring from Sainsburys - it's not great. No better than the liquid colouring options.

There are some really good walkthroughs on blogs, so have a google.
Also possible, without all the buttercream (way too rich for 2yos) is a cake by the blogger 'Not Martha Stewart'- it's her leprechaun gold trap cake (so sorry, can't link, am on phone) but it is amazing, and I think far easier than all the stacking, if you leave out all the dotted icing, and just swirl it over instead. She uses a bundt tin (like a big ring) but there's no need to. It looks awesome.
