It depends on what kind of effect you need and what strain of weed you have. First hit your bowl or role a cannabis only joint to test your weed. You will soon find out it's 'constitution'. Then get baking...
Put some Bob Marley on, make sure the subwoofer is on, then;
put about 15g good buds per 2 cups flower in any baking recipe should work well. You would be able to fill up a tin with 24 small/mini muffins. Half of one of these size should give good even flow to the experience. A whole might be a bit overwhelming an effect, much stronger than your bowl/joint earlier and of course longer lasting ride through the effects on your conscious mind.
1. Grind/chop your weed finely into the bowl with; Butter, oil or other fat source
2. add rest of [FONT="] ingredients[/FONT]
Bake at lowest temperature that with still bake OK =>160C
We don't want heat all the complex Canabinoids, the oil/fat in the recipe will do the extraction for us.
