I am thinking of making a carrot cake with a cream cheese filling. As I want to put fondant on the top, I would like to create the smooth edges as when you use ganache (so you don't get the dip between the 2 layers). My question is, will white chicolate ganache go with the taste of the carrot cake and cream cheese? Also, I have heard that you use a different ratio to cream and white choc to the ratio that you would use with dark choc as its got less coco solids. Can someone give me the ratio?

Sure you can use white chocolate ganache and it will go well with the carrot cake and cream cheese filling. I've also tried white chocolate sourcream ganache (just replaced heavy cream with sourcream). It was nice and tangy, a good complement to carrot cake.

The ratio for a setting ganache to use under fondant is 3:1 white chocolate to cream by weight. But I always end up using a tad more white choco since it've very hot and humid where I live.

Thanks, it won't be too sickly sweet will it with too much white choc?

No. Not sickly sweet at all, to my taste. But everyone's different so I wouldn't know how you'll find it. Best to just try. Oh and use real white chocolate, not choco melts, in the ganache. It'll definitely be less sweet and more delicious
