How to Make Cast Iron Skillet Chocolate Chip Cookie 

1. Preheat oven to 350 and spray a 9 inch cast iron skillet with non-stick spray.
2. Combine flour, baking soda, salt, and oats together in a medium bowl and whisk together, set aside.
3. In a large bowl, using a mixer, cream together butter and sugars until light and fluffy.
4. Add in peanut butter, egg, and vanilla and mix together until well combined.
5. Add dry ingredients and chocolate chips to wet ingredients and mix until just combined.
6. Press cookie dough into your prepared skillet, but leave a ½ inch space between dough and skillet edge to allow the dough to spread out.
7. Press peanut butter cups into dough, as many as you like, but don't press them down deep, the cookie dough will rise, so you don't want them sunken into the cookie.
8. Bake 25-35 minutes until an inserted toothpick comes out clean and golden brown. The last 10 minutes you might opt to place tin foil on top of your cookie, if it looks like it's browning too quickly.
9. Transfer from oven and serve warm, with vanilla ice cream and chocolate syrup.

Cookie Tips

• Make sure after your press your cookie dough in the skillet, that it is not taller than the skillet, as it will rise while baking.
• The deep dish baking skillets are really nice. See below what I'm using!
• You can substitute flour for your favorite gluten-free flour as well.

Iron Skillet Options & Tips

If you want to see what skillet I used, I used this Lodge Logic L5SK3 Pre-Seasoned Cast-Iron 8-Inch Skillet.  I liked it because it was deep-dish. I was impressed how the cookie baked so evenly and it was easy to clean.  (You need to hand-wash and then oil your pan to season it, so it doesn't rust and get all nasty and no dishwasher use.)

If you want a thinner cookie, you might like this wider Lodge LCS3 Cast Iron Chef's Skillet, Pre-Seasoned, 10-inch.

Here is a silicone handle that is an afterthought.  Remember these pans will sizzle your paws! So use caution when handling transferring while hot, using heavy mitts or towels.

You can find the handle here: Lodge ASHH11 Silicone Hot Handle Holder, Black and guess what I found out?  There is also a pan with a silicone handle too.  Who knew, but it's brilliant!  Lodge Cast Iron Skillet with Red Mini Silicone Hot Handle Holder, 8-inch.

I may add to my collection, this is my first cast iron skillet and I'm having fun! 🙂  You may making these Raspberry White Chocolate Pull-Apart Rolls in your new skillet!  I see more chocolate chip skillet cookies and brownies in my very near future.  Stay tuned!

If you’re looking for the perfect dessert to make that includes oats, peanut butter and chocolate to share with your family and friends, this Peanut Butter Cup Oatmeal Chocolate Chip Skillet Cookie is a must! Not only is it a crowd-pleaser, but it also requires minimal effort which makes it a total win-win.
