Oatmeal M&M Skillet Cookie

Oatmeal M&M Skillet Cookie is a fun way to make a cookie, they are made in a cast iron skillet,  baked until they are lightly browned, and are so easy to make.

This oatmeal M&M skillet cookie is one of my new favorite skillet recipes. I love cutting a slice of the cookie when they are still warm and eating them with a scoop of vanilla ice cream. Probably the next best thing to heaven.

I have been having fun making all kinds of recipes in my cast iron skillet. I purchased it in the last year and never did I dream that I would be making so many different recipes in it. I have made anything from bread to Mexican rice. And you know what? I can’t wait to see what will be coming in the future.

The last time I made this oatmeal M&M skillet cookie some of the kids were at home. They all gave it a big thumbs up. I am not sure who would not love to have a piece of this cookie. Really, it is chock-full of M&M, oatmeal, and peanuts.

Do you have to make these in a cast iron skillet?

To tell the truth, I have always made these in a cast iron skillet, but I am sure if you have an oven-proof skillet you could use that. But keep in mind that the cooking time will probably vary.

Do you have to use M&M in this recipe?

No, if you don’t like M&M or you would like to change them out you can use chocolate chips or whatever flavor of baking chips you like.
