Heres an easy way to make edibles. (These are called firecrackers they are for a single serving of edible instead of making a batch of brownies)
Go to the store and get some all natural peanut butte (the more fat the better), then gt some cinnamon graham crackers.
Now edibles can be tricky if you've never done them before and don't know how much weed to use. On 4/20 I made 2 firecrackers for myself, both with 1 gram of weed and i ate them both in one sitting. I need a high quantity in edibles to feel anything though, my friends can eat. 3-.5 and get ripped but i need at least 1.5, and i prefer closer to 3 grams though.
So you need about 2 tablespoons of peanut butter for a gram of weed ( you could use a little less probably than that) I mixed some olive oil and honey in too for a little extra fat and for a sweeter taste.
So grind up how much weed you want, and mix up everything in a bowl or something and then spread it on the graham crackers and make graham cracker sandwiches, and wrap them up nicely in tin/alumimum foil. Preheat your oven to around 325F, and then bake them for about 20 minutes.
I think thats accurate, i typed it from my phone, you can find other various firecracker recipes online
