I used microwaveable brownies once. I was using some high quality cali shit and i just crunched it into the mix! haha
I got so fucked up! I put about 2 grams in. but it was a 6" diameter bowl of brownies.
How many brownies are you thinking of making? One? Two? I made a batch of 12 and went through an ounce and a half of Bud and trim. If you're just making a few though you should be straight with 1/4-1/2 oz.
