This skillet peanut butter cookie is aย slightly under baked, gooey dessert that is easy to make in 20 minutes!

The gooey peanut butter oatmeal cookie is studded with peanut butter chips and chocolate chips and baked until it’s just set.

This is my go-to dessert when I want to make a quick and easy treat for our family. We all enjoy it with some homemade vanilla ice cream or a dollop of homemade whipped cream.

Making this dreamy dessert is really simple, but I have a few tips and tricks to help make it even easier! Don’t forget to watch the video.

No skillet? No problem. If you don’t have a 10″ cast iron skillet feel free to use a 9 or 10″ round pie dish or cake pan. I have had success with both.

Begin this recipe by combining the dry ingredients, then set them aside.

Next, melt together the peanut butter and coconut oil (or butter). If you overheat them you run the risk of cooking the eggs as you add them to the mixture.

Once the peanut butter mixture is smooth, add the coconut sugar, honey and almond milk and stir until combined.

Then add the eggs and vanilla and mix well.

Pour dry ingredients into the wet peanut butter mixture and mix until combined.

Add chocolate and/or peanut butter chips and stir until evenly distributed.

Spread the dough in the prepared skillet and bake in the preheated oven for 15-20 minutes or until the edges are just barely browned and the center is set but still a little “wiggly” when shaken.

The cookie will be a little โ€œjigglyโ€ when you remove it from the oven. It will continue to cook and setup in the cast iron skillet as it cools.

Do not over bake!ย The cookie will not look done when it is, in fact, done. Plus, it will cook more in the skillet once it’s removed from the oven. Over baking will ruin the cookie and turn it from a gooey dream to a dry cakey mess!

Serve

Serve this peanut butter skillet cookie warm with a scoop of your favorite ice cream (chocolate ice cream or vanilla). We also like to add a dollop of homemade whipped cream and a drizzle of chocolate sauce or melted peanut butter.

You can serve it on individual plates, or just give each family member a spoon and dive right into the skillet!

Store/Freeze

Store leftovers in an airtight container in the refrigerator for up to 1 week or in the freezer for up to 2 months. Reheat in the oven set to warm or in the microwave to restore the gooey taste and texture.

Can I use a different pan than a cast iron skillet?

Yes, use a 9″ round cake pan or 9×9″ baking pan.

Can I double this recipe?

Yes, double it and bake it in 2 skillets, 2 pie dishes or a large 9×13″ pan.

    We have had never-ending snow days, which makes me want to bake! I made this Teo days ago, and we loved it so much, I am making it again tonight. It is so soft and so delicous!

  2. I’m looking for Keto cookies that are low on sugars for my son. Will omitting the marshmallows and chips reduce the carb intake on the sugar side? They look delicious and I’m saving this recipe…

  3. 5 stars
    Those are amazing! Tonight’s is the second time i am making them. I am a vegan so I easily substituted the 2 eggs with 2 tablespoons of ground flaxseed and mixed it with 6 tablespoons of water to make up for the eggs and they turned out wonderfully. Thank you for the yummy and easy recipe.

  4. Oh man! This looks absolutely amazinnnggg. Perfect way to use my giant cast iron skillet – and so happy they’re gluten-free and dairy-free!

  5. oh, sister. i fully support your pregnancy cravings with this one… this looks just like my love language too. and i have all of this in my pantry right now. watch out.

  6. 5 stars
    I made this today for guests and it was amazing. I used the gluten free all purpose flour and maple syrup options and it turned out insanely delicious. Perfect amount of peanut butter and chocolate while still tasting like a cookie that many people would enjoy. Super easy to make. Everyone loved it. Highly recommend!
