Has anyone else had the problem of the coconut oil separating from the HWC? When I took mine out of the freezer there was a layer of cocobut oil on top. They still tasted pretty good though. I made a plain batch with just CO, cocoa and splenda and the splenda all sank to the bottom! I don't have any no carb sweetner and I need to use up the splenda packets I have first. Anyone have any tips or suggestions?
