Chocolate Chip-Peanut Butter Oatmeal Skillet Cookie

A cookie goes from ordinary to extraordinary when baked in a skillet. This Chocolate Chip-Peanut Butter Oatmeal Skillet Cookie is best eaten gooey and warm right out of the oven with a scoop of vanilla ice cream. And maybe even a little drizzle of hot fudge sauce.

Seriously. This skillet cookie is so indulgent, you might as well go all the way with it.

Make a skillet cookie and you may never want a regular cookie again. They are so amazing.

The best part is the middle stays really soft and gooey, but the cast iron pan gives a wonderful chewiness and crispiness to the edges.

Use a Cast Iron Pan

And that’s the secret to a great skillet cookie- a cast iron pan. If you don’t have one already, a cast iron pan is probably the best kitchen investment you can make. You can use it for just about anything and if you take care of it, it will last you forever.

The combination of oats, peanut butter, and chocolate chips in this skillet cookie just can’t be beat. So much flavor and so much gooeyness!

Chocolate Chip-Peanut Butter Oatmeal Skillet Cookie Recipe Tips

Milk chocolate chips can be used instead of semi-sweet or you can use peanut butter chips if you only want peanut butter flavor.

I use salted butter, but you can use unsalted and add a pinch of salt.
