Ingredients

Instructions

  • Preheat the oven to 350 degrees F.
  • Combine the butter, brown sugar and granulated sugar in a large bowl, then use a hand mixer on medium speed to blend ingredients together. Whisk on medium until the mixture is fluffy.
  • Next, add the eggs and vanilla to the bowl, and use the hand mixer on medium speed to whisk until combined.
  • Combine the flour, baking soda and salt in a separate medium-sized bowl. Mix by hand until combined.
  • Add the dry ingredients to the wet ingredients in the bowl you mixed earlier. Mix this on low speed with the hand mixer until well combined.
  • Toss the chocolate chips, peanut butter chips, and the peanuts into the bowl and mix by hand so you don't crush this ingredients. Mix by hand until combined.
  • Grab your 10-inch or 12-inch cast iron skillet (you can also use mini cast iron pan, use two 6-inch skillet if choosing this option) and either spray with non-stick spray, or grease with some butter or shortening.
  • Next, carefully spoon the cookie mixture into your skillet, or mini skillets. Smooth out the top with a spoon or offset spatula.
  • Place the skillet, or mini skillets, in the preheated oven and bake for about 25 to 35 minutes.
    You can use a toothpick inserted in the middle to test for doneness. If it slides out clean the cookie is done. That said, I like to underbake mine just slightly so I tend to pull it out a tad early.
  • Carefully remove skillet, or mini skillets, from the oven. Place on a cooling rack or board to allow it to cool slightly.
  • You can eat the skillet cookie on its own, or you can top it with ice cream, whipped cream, or both if desired. Cut cookie into slices, or serve in skillet and let everyone dig in.
    Personally, I think this dessert is best served warm.
  • Serve warm or cooled.
