We're making cookies, but making them in one large skillet form, large enough to share... or not to share. This cookie skillet has the best types of candy and chocolate incorporated in it, that's why it's called the best kitchen sink skillet cookie. From chocolate chips to peanut butter pieces, there's deliciousness in each and every bite.
Who doesn't love cookies any time of year? This cookie skillet is great any day of the week, but it's even sweeter when celebrating birthdays, holidays, or special occasions.
This was inspired by my original, GOAT, the triple threat cookies. Packed with three different types of chocolate, I knew I had to make this similar recipe in larger form.
What ingredients do I need for this recipe?
For this cookie skillet, you'll need almost the exact same ingredients as you would for the triple threat kitchen sink cookies, the only real difference is the bake time. In the recipe below, I will offer up a few different ingredients you can swap in to make this cookie skillet even more exciting.

- Baking Soda
- Cane Sugar
- Light Brown or Dark Brown

How do I make this recipe?
Steps for making this cookie skillet is very similar to that of making cookies, only we add the entire batter to a cast iron skillet and baked for longer time.
Preheat the oven to 375º and grease a cast-iron skillet with butter or cooking spray. Set aside. In a large bowl, cream together the butter and sugar until it's light and fluffy, approximately 3-5 minutes. Crack in the eggs and whisk to combine. Pour in the vanilla and whisk again.
To the wet ingredients, pour in the flour, baking soda, and salt. Fold in with a spatula until half of the batter is formed. Crush the chocolate pretzels and add to the batter, and pour in the m&ms, and peanut butter pieces. Continue to fold in the ingredients until fully combined.
Once the batter is formed, pour into the pre-greased cast-iron skillet. Push the batter flat and around the entire surface of the cast-iron skillet, making sure there is an even distribution.
Top with extra chocolate chips and m&ms. Bake for 30 minutes. Once done, let rest for 5-10 minutes before serving.
Hint: Be sure to spread the cookie dough evenly across the greased cast iron skillet so that it bakes in an even layer.
Recipe Swaps and Substitutions
If you are looking for ways to modify this recipe and substitute specific ingredients due to dietary restrictions or allergies, here's what I would suggest:
- Flour - instead of using all purpose flour, I would suggest using a 1:1 gluten free flour here.
- Sugar - if you want to lower the amount of sugar in this recipe, you could swap for coconut sugar instead of using cane and light brown. The texture and the flavor will change a little.
- Peanut Butter - feel free to omit the peanut butter pieces entirely if you are allergic to nut butter.
While this recipe is built on making this is one large skillet with several mix-ins, here are some different ways you can vary the mix-ins as well as how you bake it!
- Mini Ramekins or Skillets - you could divide the batter into smaller ramekins for individual cookie cups or skillets to make them fun kid-sized desserts.
- Mix-Ins - if you want to change the different candies and chocolates used in this cookie skillet, you can use:
- Chocolate covered fruit
- Chocolate covered nuts
- Graham crackers
- Chocolate kises
Kitchen Equipment and Tools
Having a few trusty baking tools in your kitchen really makes a difference. Here are a few must-haves if you're looking to make this skillet every single time:
- Large cast-iron skillet
- Off-set spatula
- Hand or stand mixer - I only have a hand mixer, and I love it!
- Cookie scoop
One other kitchen tool that I rely on heavily is the use of a scale. Kitchen scales help to make sure that the recipe turns out the exact same each time. A gram is a gram, however, a cup is not the same as a cup for me and for you. Why? We all scoop flour or sugar differently, so when we measure, we are getting the same weight each time. I highly suggest investing in a quality scale, I promise you it makes a difference. Some of my favorites are listed here.
How do I store this recipe? Can I freeze it?
You can cut the cookie skillet into smaller pieces and place in a tightly sealed container and leave in the fridge for up to 3-5 days. You can also place in the freezer, which will stay for up to 2 months.
Add some flakes of sea salt on top of the cookie skillet when it's done baking for an added crunch and a bit of salty flavor. It pairs really well with chocolate!
