Well, dude, first off, 4 grams in one cookie or brownie isn't exactly something you can just do. If you know a box of brownie mix or a cookie recipe for making just one brownie or cookie, good. But that doesn't matter, if you really wanna bake something, which is gonna take a lot longer to do, you get your box of bretty crocker or whatever brownie mix and use a double boiler (one pan with water and one with butter on top of the one with water) and cook the weed in the butter for about an hour and you drain the weed out from the butter and add it to the mix. Bake. Eat and "baked." Simple.
