Chewy peanut butter M&M cookies are always a welcome treat at our house. Baking them into a big skillet cookie makes the process even easier and gives you lots of the best chewy center parts. It is peanut butter and chocolate cookie goodness at its finest!
This post was originally from 2015. I thought it was high time to make this bad boy again.
When I pulled up the post, the pictures of Little Dude melted my heart. He was always been such a helper.
I couldn’t bare to take those pictures out. He is just too dang sweet. But I did update the pictures of the cookie itself.

I will let you read the original post and see the fun pictures of little dude from when he was an itty bitty sous chef.
I don’t know if you guys know this or not, but I have a sweet tooth. I thought I might go ahead and fess up to it!
I also love all things chocolate and peanut butter. I mean, that does go without saying right? So I just couldn’t help myself when I saw a bag of peanut butter M&Ms on sale at the store.

I had been wanting to make some cookies, but sometimes cookies take too long! You have to wait for the butter to come to room temperature, make the dough, put it back in the fridge to firm up, scoop the cookies, bake the cookies.
I am a little impatient sometimes (keep your comments to yourself, MiMi!) so I need to have a shortcut.

A skillet cookie solves some of the time issues. You can use melted butter and can bake it right away because you don’t have to worry about the cookies spreading too far.
Plus it just takes one trip to the oven, no worry about doing a sheet at a time!

The melted butter also made it much easier for Little Dude to stir as well. So it was win, win.
He has so much fun helping in the kitchen. For this project he got to crack the eggs, dump the ingredients in the bowl, and stir them up.
He also enjoyed pushing the dough into the skillet and spreading it around. But his favorite part was putting some more M&M’s on top.
Our cookie might have been missing an M&M or two, but it was still delicious.

The cookie slices best if you wait a while first. Little Dude and I couldn’t wait, so we had crumbly but delicious first slices.
My husband and a friend were installing some siding for a couple of friends, so Little Dude and I delivered some pieces to them. The extra wait time made those pieces come out much better.

We also loaded up some pieces in the wagon and walked them over to my brothers’ house. Our cookie delivery service did not get any complaints!
This cookie is everything you would want from a skillet cookie. It is thick and soft in the middle with just a little bit of crunch around the edge. But don’t take it from, try one yourself!
