I do it without the nuts.

Melt some coconut oil in a pan, mix in some sweetner and cocoa. then shreded, unsweetened coconut. spread out in a pan, thin if you can and refridgerate.

The best oil and unsweetened coconut I've found is from wildernessfamily naturals. Their coconut has a drying process that makes it taste just like candy
