Just make hash man and mix it in the brownies man..

Take a mason jar, put a little less that half the jars amount of 100% rubbing alcohol in it, put your ground up weed in.

put the lid back on

shake shake shake shake shake for like 15 or 20 minutes

Put all of it in a coffee strainer paper thing that goes in the coffee maker, twist up the end and squeeze the living shit out of the bad into a small sauce pot

Once you did that, heat the contents of the sauce man until almost all the alcohol evaporates off.

Once theres hardly any left, take a grill lighter and light the rest of the alcohol in the pot on fire. it will burn off and leave you with hash at the bottom of the pot.

after you did that, you can just mix it in your brownie mix and cook.
