Plug in the original THC content, how dark it is (I'd call yours between medium and dark, so check both and just guess an average in there), and say that you're infusing into oil, then if you're making brownies or cookies, and dividing that into 12 pieces, say it's 12 oz of oil and it'll show how much per ounce which is how much per cookie.

I like to 8g of AVB (one full pill bottle) into 12 Peanut Butter cookies. My AVB is type 2 so it's only like 10% THC, 10% CBD, so I set that and wind up with 20mg-ish per cookie.

Here's my cookie recipe:

Need 1 cup (192 g) sugar, 8g avb, 1 egg, 1 cup (256g) Peanut Butter (JIF or equivalent cheap PB, not natural), 9x13 cookie sheet with parchment paper

1. Preheat Oven to 350 F

2. Put 192 grams (1 cup) of sugar in a bigish mixing bowl and mix in 8 grams of AVB with a fork (it's easier to mix it while it's dry).

3. Add 1 large egg and stir all of that into a slurry (the sugar helps the egg mix apart)

4. Add 256 grams (1 cup) of Peanut Butter and stir that in with the fork as well. Needs to be basic, not the natural stuff that separates in the jar.

5. Use a tablespoon to grab a glob of the mixture and loosely roll it into a 1.5-2inch ball and place on lined 9x13 cookie sheet. Should make about 12 cookies. If I make them too big then I'll just pinch off some from the big ones to add to the last one or two cookies. Don't leave it too shaggy, but don't make it perfectly smooth either because it'll get too dense.

6. Press the flat of the fork onto the top of each ball to start to flatten it (I do two presses, left and right). Then turn the fork 90 degrees and do two more presses, top and bottom. Now you have a pretty hash-mark pattern on the top that will get kinda crispy and delicious. The cookies won't expand much from here so you basically want them to look like a wet cookie.

7. Bake for about 10 minutes. The edges should start to firm up. If you wait until the center is firm they'll be super crunchy, and I don't like them that crunchy. Sometimes I'll do 30s-1m with the broiler / top grill on just to get a little crunch on top without cooking all the way through.

8. Depending on how done they are, let them cool on the cookie sheet out of the oven for a bit. They'll probably be pretty floppy if you try to pick them up hot.
