Help I need two similar but not matching cakes for an 18yo & a 7yo

[Katymac]

My mum will have both her grandaughters with her this year between their birthdays so we are having a big(ish) party

My Dd will be 18, my niece will be 7

DD has a fruit cake (already made) 10 inch circular, my neice will have a chocolate sponge (probably)

They both like Frozen, but I'd rather DD's 18th cake is a little more adult/less Disney

But I am stumped - any ideas at all?

I could do niece a Elsa cake with a doll - or cake with an Olaf on but what do I do for my Dd then?

NB I am not a natural cake decorator but I 'cheat' well; these are pics of DD's 16th

Could the older DD have a frozen coloured cake ie pale blue with white snowflakes etc with the younger one more character based?

I can't seem to post the pics there is one on my profile

Maybe - but she isn't really into Blue

It's tricky

I suppose they don't 'need' to match I was just being tidy

Or more spring like colours from frozen fever

That could work

How about something like this for the 18th

And then like this for the other one

What about white with white snowflakes, a whiter version of this. If DN has Elsa, with blue snowflakes of the same style, that would tie up??

Maybe I should forget the frozen idea

DDis also interested in Music/Dance/Disney...

& I don't know my niece very well as she lives abroad

Mlaybe I could do DD a carribean paradise &still do Olaf andit could be 'In Summer!'

No feeling inspired just challenged

Minnie Mouse.... Your dd do pink and white spots with a bow. On the 7 year old add ears and cover in pink , add eyes and nose bow between the ears etc
I did a similar thing but did cupcakes for the older ones.

Not Minnie Mouse - DDwould have kittens!!

Something lion king maybe?

Thanks for everyones help - I just. don't know what DD would fancy I'll keep trying out ideas and really appreciate everyone's suggestions

I quite like [[http://www.telegraph.co.uk/foodanddrink/recipes/10073362/Chocolate-flowers-cake-decoration.html

& this is gorgeous but outside my capabilities

I'd do two versions of those maltesers spilling out of a bag cake. One maltesers and all chocolately and one skittles or some thing sweetie like.

something like this is deceptively easy

I'm still dithering about chocolate decorations on a fruit cake

She spotted a white chocolate & pink version

Ah yes choc on a fruitcake maybe not. You could do one cake for both 'happy 25th birthday'?!

Now my dad would like that!

If you do M&M's spilling out you could get your DDs photo put on them.

Www.mymms.co.UK

I did that for my goddaughters 21st and it ammused her to give them to her friends

OK DD has decided on the night sky layer of the Lion King cake & that my Niece would like an actual Elsa cake

Oh bugger!
