Equipment at a Glance
To whip up this delicious skillet cookie, you will need:
- Oven-safe skillet: A cast iron or non-stick skillet works best.
- Mixing bowl: For combining your wet and dry ingredients.
- Spatula: To mix your batter and spread it evenly in the skillet.
- Measuring cups and spoons: For accurate ingredient measurements.
- O Organics Canola Oil Cooking Spray: To ensure your cookie doesn’t stick to the skillet.
Mastering Chocolate Chip Marshmallow Skillet Cookie: How-To

Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your cookie bakes evenly and achieves that golden-brown perfection.
Step 2: Prepare Your Skillet
Spray your oven-safe skillet generously with O Organics Canola Oil Cooking Spray to prevent sticking. Set it aside while you prepare the cookie batter.
Step 3: Mix Wet Ingredients
In a large mixing bowl, whisk together the melted unsalted butter, granulated sugar, light brown sugar, and the large egg until smooth. Add in the O Organics Madagascar Vanilla Extract and mix well.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the O Organics All-Purpose Flour, baking soda, and salt. Gradually add this dry mixture to your wet ingredients, stirring until just combined.
Step 5: Fold in the Goodies
Gently fold in the mini marshmallows and 3/4 cup of chocolate chips into the cookie dough. If you’re using nuts, add them here too!
Step 6: Transfer to the Skillet
Spoon the cookie dough into your prepared skillet, spreading it out evenly using a spatula. Sprinkle the remaining 1/4 cup of chocolate chips on top for that extra chocolaty goodness.
Step 7: Bake
Place the skillet in your preheated oven and bake for 25-30 minutes, or until the edges are golden brown and the center is set but still slightly gooey.
Step 8: Serve and Enjoy
Remove the skillet from the oven and let it cool for a few minutes. Serve warm, ideally with a scoop of ice cream on top, allowing it to melt into the cookie for a delightful treat.
Flavor-Forward Alternatives

Feel free to get creative with your Chocolate Chip Marshmallow Skillet Cookie. Here are some alternatives to consider:
- Nut Variations: Swap out walnuts for pecans, or leave them out entirely for a nut-free version.
- Chocolate Choices: Experiment with milk chocolate, dark chocolate, or even white chocolate chips.
- Flavor Enhancements: Add a sprinkle of cinnamon or a dash of espresso powder for an extra flavor kick.
- Mix-In Additions: Try adding crushed graham crackers for a s’mores flair or dried fruit for a chewy texture.
What Could Go Wrong
While this recipe is straightforward, here are a few common pitfalls to avoid:
- Not measuring ingredients accurately can affect the texture of your cookie.
- Overmixing the batter may result in a tough cookie instead of a chewy one.
- Not using enough cooking spray can lead to the cookie sticking to the skillet.
- Underbaking might leave you with a raw center; ensure the edges are set and slightly golden.
Leftovers & Meal Prep
If you happen to have leftovers (which is rare!), here’s how to store and enjoy them later:
Allow the cookie to cool completely in the skillet before covering it with plastic wrap or transferring it to an airtight container. It can be stored at room temperature for up to 3 days. For longer storage, consider slicing the cookie and freezing individual pieces. Just reheat in the microwave for a few seconds when you have a craving!
FAQ
Can I use coconut oil instead of butter?
Yes, you can substitute melted coconut oil for the unsalted butter. It will impart a subtle coconut flavor that pairs well with chocolate.
What if I don’t have a skillet?
If you don’t have an oven-safe skillet, you can use a regular baking dish or a cake pan. Just make sure to adjust the baking time as needed.
Can I make this cookie gluten-free?
Absolutely! Just replace the all-purpose flour with a gluten-free flour blend that measures 1:1 for best results.
How can I make the cookie chewier?
For a chewier texture, try using more brown sugar than granulated sugar, and avoid overbaking it.
