Ganache is what Chocolatiers make, its about half double cream and half dark chocolate 70% to 80%. Warm the cream till it simmers, then pour into a bowl where you have already chopped up your chocolate. Mix it, leave it in the fridge to set, then make little balls using a teaspoon. You can roll it in chopped almonds or Green and Blacks cocoa powder, pop them in the fridge. Its a bit messy to roll but hey you get to lick your fingers.
I've made this with un sweetened desiccated coconut, they are a bit like bounty bars. I've also made them with a bit of sweetener in, but didn't like the results. 1) they were too sweet and 2) the sweetener can give you the runs.
