I think what I really need is a good chocolate glaze, but I'm wondering if there might be a chocolate ganache out there that sets. I have a request for cupcakes that are going to be schlepped.

I'm trying to replicate the Boston Cream Cupcake, and I know that where they are going there will be no refrigerator space; hence the need for the non-dairy pastry cream as well.

I looked at Alton Brown's Chocolate Glaze for Doughnuts but since I haven't tried it maybe someone else might have a better suggestion?
