Thank you so much for your advice. I'm waiting to hear back and hopefully I'll get a clearer picture soon of what she wants.
Oh and Becky I'll definitely do a taste test soon to see how they taste.
And ChesterV, wouldn't the white chocolate melt out in the sun? I love the idea but I'm afraid it might get soft or melt.
No, there is hard white chocolate you can use, it will not melt in the sun, only over high heat. You have to work with it very quickly though on the cake before it sets up. And of course you would have to do three or four coats if you use it thinly.
If you can find some videos of the bakery Choccywoccydoodah, all they use is white chocolate. And they put it on pretty thick too.
You just have to have a very sharp knife to slice through the chocolate so it doesn't break apart.
Although, I guess if its out in the sun, it should be supple enough to cut with any knife.
The chocolate also works as a "hold barrier", as its stiff enough to take a hard ride in a delivery vehicle without the cake possibly sliding around or off.
