How To Make Lump Of Coal Cookies
Melt the butter in a pot over medium heat.
Add the marshmallows and stir until they are melted and the mixture is smooth.




Take the pot off the burner and mix in the crushed cookies until well combined.
Drop tablespoon scoops of the mixture onto a prepared sheet pan.
Leave the cookies at room temperature until they are set and cooled.





Storage
Once the cookies have set at room temperature, transfer them to an airtight container. They will keep at room temperature for up to two to three days. The less air they are exposed to, the better!
Freezer: Lump of coal cookies should freeze just fine. Once they are cooled store them in a freezer container and they will keep for up to two months. Thaw them at room temperature before serving.
Pro Tips
- Make sure your mini marshmallows are very soft and fresh. If they are even a little bit stale, your cookies won’t be as soft and chewy.
- Once you’ve added the marshmallows to the melted butter stir just until they’ve melted. You don’t need to cook them further.
- Use a small cookie scoop to make it easy to form even-sized cookies. If you don’t have one, a tablespoon will work.

My neighbor doesn’t like Oreo cookies. What else can I use instead ?
Oreos are going to give you that classic dark color like coal. I’m not sure how to get that color without using Oreos. My only thought is to try a chocolate cereal so they are like a Rice Krispies treat.
Use any cookies add a little black food coloring paste
Thank you Melissa!
I’m sure you can crush up chocolate chip cookies, or a chocolate cookie to make it like coal. Or just use chocolate pebbles cereal
Thanks for your ideas Mandie!
will not last long enough for Christmas gifts. they might be a day or two before eating not a good idea
These are best enjoyed fresh, but will keep for 1-2 days in a airtight container at room temperature.
