It’s officially winter here in Tennessee. While I’d much prefer snow, we usually get freezing rain.

Some days just call for a Peanut Butter Chocolate Cookie Skillet. One good thing about the freezing rain though, is it shuts everything down and I get to stay home and bake!

I love peanut butter! If I make a PB&J it’s mostly peanut butter with a little jam. Jamba Juice has a smoothie called Peanut Butter Moo’d which is my favorite and I get it every time. My husband even makes a mean peanut butter bacon burger with pickles that is amazing!

So when I woke up to a beautifully frozen landscape, and I knew I’d be stuck at home for the day, I needed to make a warm, gooey treat! This Peanut Butter Chocolate Cookie Skillet satisfies any peanut butter craving! If you like Peanut Butter at all like I do, you are gonna love this Peanut Butter Chocolate Cookie Skillet recipe. 

This is a recipe I grew up with.

I’m not sure where the recipe came from originally. As an adult, for years I have just been making it from a handwritten notecard.

Originally, we made these as bars in a 9×16″ glass pyrex baking dish. They come out a little thinner, but still delicious.

If you don’t own a 10″ cast iron skillet, you can still make this recipe. All that needs to be changed is your baking time. Decrease it to 18-20 minutes. I love my cast iron skillets though! They bake things so nicely! The one I’m using here is a Lodge 10.25“. Cast iron skillets last forever and only get better with time. They are a great kitchen investment for sweet or savory recipes!

This recipe for a Peanut Butter Chocolate Cookie Skillet is quick and easy.

Preheat the oven to 350 degrees and very lightly oil the cast iron skillet. I like to use coconut oil!

Just like most cookie recipes, start by creaming the butter and sugar together, and then mix in the peanut butter.

Next, add in the egg, milk, and vanilla and whip it until the batter becomes a lighter color and becomes fluffy.

Sometimes the peanut butter likes to stick to the side of the mixing bowl, so you might need to stop and scrape everything back into the center of the bowl before you continue mixing. Lastly, add in the flour and oatmeal, mix until combined, and scrape it all into the cast iron skillet. Smooth it all around evenly and bake! Because the cast iron is thick, it takes a while for these to bake. It took a full 30 minutes for mine to be done in the middle. The cookie should look golden brown, raised up all over, and if you stick a toothpick in the middle it should come out clean. 

As a kid, I used to think this next part was magic!

Immediately after you get the skillet out of the oven, evenly pour the cup of chocolate chips over the top. These need to sit for about 10 minutes before the magic can happen.

Mom always knew the exact moment it was time to spread the chocolate chips. She let me in on the secret, so I’ll share it with you too, it’s when they all look shiny! 

While the chocolate chips are melting, it’s time to make the peanut butter frosting.

If you’re making this with your kids, this is also a fun job to give them! 

In a container with a leak-proof lid, add in the powdered sugar, peanut butter, and milk. Place the lid on tightly and let them shake it up! 

The ingredients will all combine to form a super delicious peanut butter frosting that is drizzle consistency!

Finally, to finish off the Peanut Butter Chocolate Cookie Skillet, you can either drizzle the peanut butter frosting with a spoon or spread it over the melted chocolate with a butter knife.

Or, if you want to get extra fancy, scoop it all into a small ziplock bag, cut a little bit of the corner off of the bag, and pipe it over the top! No matter which method you choose, these are going to taste amazing!

You can enjoy this Peanut Butter Chocolate Cookie Skillet while it’s still warm, but it is also great after it has cooled down. The chocolate chips will set back up giving a nice contrasting snap to the soft peanut butter cookie underneath! I hope this satisfies your peanut butter cravings as it does mine! Enjoy!

Instructions

Peanut Butter Cookie

• Preheat oven to 350 degrees and very lightly grease a 10″ cast iron skillet.
• In your mixer with with paddle attachment, beat together 1/2 cup butter, 1/2 cup sugar, and 1/2 cup of brown sugar. Add in the 1/3 cup of peanut butter and whip ingredients together on medium speed until combined.
• Next, add in the egg, 1/4 cup of milk, and 1/2 tsp of vanilla, continue mixing at medium-high speed until the color of the mixture lightens and turns fluffy about 3 minutes. You may have to scrape the sides to ensure the peanut butter is getting fully incorporated.
• Finally, pour in 1 cup of oatmeal, 1 cup of all-purpose flour, and a 1/2 tsp of baking soda. Mix batter until everything is combined.
• Using a rubber spatula, scrape the mixture into the cast iron skillet and evenly spread it around the pan.
• Place on the middle rack of the oven and back for 30 minutes, or until golden brown and the sides and middle have risen. If poked in the middle with a toothpick, the toothpick should come out clean.

Cookie Topping

• Immediately after the skillet comes out of the oven, pour 1 cup of chocolate chips evenly over the top and allow them to sit for at least 10 minutes.
• While the chocolate chips are melting, in a small container with a tight-fitting lid, combine 1/4 cup powdered sugar, 3 tbsp of peanut butter, and 3 tbsp of milk. Place the lid on tight and shake the contents for a couple of minutes until they are combined.
• After 10 minutes, use a butter knife to spread the melted chocolate chips evenly around the top of the skillet cookie. 

Pour the peanut butter frosting into a small ziplock bag and cut the tip off of one corner. Evenly drizzle the peanut butter frosting over the top of the melted chocolate.

For a pretty design, use a toothpick to draw lines through the frosting.
• This skillet cookie is delicious served warm and gooey. But also has a nice chocolate snap once the topping has cooled and set!

Enjoy!
