What to do with 1 cup of leftover chocolae ganache?

it is great with sugar cookies. if you want to add some flavor, put some peppermint extract in it

Peppermint Truffles in a Mug!

Hot chocolate?

over vanilla ice cream?

There's a recipe for espresso bean shortbread kicking around on the Internet... I've made it a couple of times (probably Martha Stewart) you use a wooden spoon to get the line down the middle of the biscuit... two little bean shaped shortbreads filled with some chocolate ganache would be very tasty! I'd also consider an almond or coconut macaroon, or a fancy macaron!

Send it to me!

Warm it up (thin it if necessary) and voila! Fondue!

It freezes beautifully.

make truffles!!!

Dip half of your cookie in it! Or make macaroons and use the ganache as filling.
