@clerahi - So after a bit more thought because I know your granddaughter definitely has a Chocolate/Maltesers theme going on, what do you think of these?
I know the above one is a little plain, but you could add the rainbow behind the unicorn, make the board all bright rainbow colours, add flowers and things to it to jazz it up. You could even tie a Rainbow 'Bow' around the Fingers.
This is done in a similar way to the way I made my Ferrero Rocher Cake.
Here is a step by step tutorial on how to make the Ferrero Rocher Cake. First, make the cake; I made a 6-inch marble cake; however, you could make any flavour of cake you like including this chocolate cake. To make the marble cake the same as mine, follow the Chocolate cake instructions but...

Or this was the chocolate covering option. I would jazz the board up so that the cake pops on the board. (Pops = Stands out more).
It never dawned on me until last night that we could use the chocolate to cover the whole thing, and all the bright colours would literally pop against the backdrop. The thing with the top cake is that the Fingers and Maltesers would hide any imperfections with the covering, and then you can decorate it.
Thanks Angie,
Definitely a 3D topper.
Thinking this through, a chocolate cake (rather than a cake covered in chocolate) with a rainbow inside would need to be something like this where the buttercream is coloured?

Five days off after today when I can think this through and decide.
As for the rainbow effect you mention above, yes, if you didn't do the cake layers in colours, you could dye the buttercream. However, the more layers you make by cutting through the cake and the more buttercream colours you put in, the thinner the cake becomes, and you effectively destroy its structure.
If you want to do this, you need a cake leveller to make very thin layers of the cake and then fill each layer and build it up. If you had a few cakes under your belt, I would say give it a go, but because you've not made many, I need to advise you on what may go wrong. (As there will be multiple layers, they will be very thin, the problem with that is when you lift and stack them they could, sag, bow or break because they become brittle). But if you're happy to do it and think you can pull it off, then yeah, go for it.
Or, as another option to keep the rainbow effect, do something like this.
Then you wouldn't have to coat the outside of it, and then you could just put the unicorn on the top.
If you made a normal sponge rather than chocolate, there are many ways of making it colourful, but because you're looking at chocolate, you're limited to what you can do. If you're intent on the rainbow inside then, I would dye the sponges and not the buttercream. If you scroll down the below tutorial, you will see how to dye cake layers.

However, you could get the best of both worlds if you do this. (Tip 60 of
my book).
You get the bright rainbow effect she's looking for with the chocolate covering. You could then add sprinkles to the outside of it. If you covered the rest in chocolate like the below cake, you could add rainbow sprinkles to the base and place random bits on the cake as shown.
You could also take elements from each of the above cakes and make your own version. It would be best to think about what you can do, how much time you have to do it, what equipment you'll need etc. Please be aware that cakes/decorating do take a lot of time.
The good thing about your cake is you can make the decorations first and then make the cake another day.
Once you've finished at work, have a look at what I've suggested. (You may come up with something completely different).
When you have a clear picture of what you want to make, I can then advise you of the cake, sizing, models, and colours you'll need.
