HELP please, making pot oil/brownies

im making some special brownies the mixture calls for oil so my questions are is corn oil ok? and how long and in what do i cook it?

Well Butter would be better, but oil just grind material up in a coffee grinder, not too much and put in crock pot and add however much oil recipe callls for, then cook on low for 4 hrs. strain and use. Material will get dry and thc will be one with oil.

Youtube that shit. Good recipes on there

couldnt you just simmer the oil/weed in a pan? and in the crockpot,, would you add waterwith the oil like the butter recipe calls for?
