Anyone know a goo sugar free chocolate sauce i can make?? Possibly one that doesnt require me using a sugar-free syrup as that doesnt exist in our town... Do you think you could use agave nectar plus unsweetened cocoa and a bit of vanilla to make it work?

I've made it with Hershey's cocoa powder, water, and splenda (or approved sweetener of choice). You cook in a saucepan over medium heat until it bubbles and reaches desired consistency.
