This idea I got from Pinterest. It blew my mind, just as much as the cake and soda thing. Sorry there aren’t more pictures, this was kind of a fast process and, well, I forget. You ever forget? It happened to me.
So you take an entire pack of Oreos (double stuf of course) and grind them to smithereens in the food processor. I hope that’s how you spell smithereens. Fun word.

This process is fast, so you want to have your pan ready to go. Take a sheet of wax paper and shove it in a 8×8 pan. (I guess you could use 9×9 but they’ll be a little thinner.) The paper won’t stay, but that’s okay for now. Rub butter all over it so that your treats won’t stick. Trust me, wax paper doesn’t taste so good.
Then in a large microwave-safe bowl, you take 5 cups of marshmallows – I used the minis (and yes this is how I measure a “cup” or marshmallows), and melt it with 4 tablespoons of butter (half a stick) until the marshmallows get puffy and the butter is melted (takes about 2 minutes, at 30 sec intervals).

After it comes out of the microwave, stir in 1/2 teaspoon of peppermint extract. You can leave this out if you want, but I tried it both ways and with peppermint was much tastier!
Dump in the Oreo crumbles and mix mix mix until you can’t mix any more… It gets very hard, so have a strong man handy if possible to do your stirring. Once it’s good and mixed up, scoop it all into your pan and press it in as hard and as flat as possible. Make sure you get it good in the corners and everything. You want your coal to be pretty, right?
Now comes the hardest part. You have to wait. I did this in the evening and waited until the following evening to cut it. I’m guessing a couple hours would do it though.
Once the waiting is over, pull up the wax paper and pop out the massive chunk of coal and cut up into little squares. There you have it, Chrsitmas Coal!

The texture is kind of like a tootsie roll. Chewy, soft, just a slight minty flavor… and come on – you can’t go wrong with something created from Oreos!

I suspect kids would love this recipe, and it’s something they could definitely help with. Plus, it’s fast and easy, and doesn’t take much planning. I hope you will try it!
