thc butter? what the hell??? You just wasted your money on that bag, buddy. There was more thc in it before you made it into butter.
if you wanna make cookies the best way to get the thc into them and therefore into you is to melt the butter and fry the pot up in this without burning it (burnt pot...ewwww!) this is what I presume you are referring too and I don't really know but make some cookies and chuck them in the freezer and they should last as long as you can manage not to eat them!!
