Bud brownies are cakes (brownies) with marijuana in them. Variations on this include hash cookies, pot-cakes etc. All work on the same basic recipie and they can be easily made by using the following "recipie":

Take the instructions off the back of the box for the muffins or brownies and follow it, to plan except for one difference...When you get to the butter part, take the instructed amount of butter out, put it in a saucepan, once the butter starts melting put around 3 grams (you may as well put a half q in but its okay if you use less) of your bud in. Now before you put it in chop it up, and you're going to want to chop it pretty fine so you dont have to chew on any buds when you are eating your brownies. Put the chop into the saucepan of butter and stir it around for a few minutes being careful not to burn the mixture. This does two things,
1)Binds the marijuana to the butter
2)Heats the marijuana in order to release THC
You can do this a few times if you please but it should all soak in the first time. Most of the pieces of bud will disappear and the butter will turn green, so when this has happened pour the butter out into a container and put it into the fridge to set it, then use it as normal butter in the recipie. Bake the brownies in the oven as usual and voila, you have bud brownies!
