Recipe at a Glance
- Bake Level: If you've ever made cookies before, this is even EASIER than that! Cookie dough baked in a cast iron skillet, it's too easy.
- Bake Time: This skillet cookie bakes for just 30 minutes.
- Taste: The premise of a kitchen sink skillet cookie is having all sorts of flavors in it. Salty, sweet, crunchy, chocolatey, and buttery.
- Swaps and Subs: You can virtually sub in any type of ingredient you want such as potato chips, peanut butter cups, pecans, walnuts. Swap out the flour for 1:1 gluten free, and use dairy free butter instead of regular butter.
- Best Served With: Serve this up a la mode with a heaping scoop (or scoops) of chocolate, accompanied with a classic Italian tiramisu, a batch of soft lemon sugar cookies, or my classic chocolate covered strawberries.
Trusted Tips and Tricks
- Sprinkle of Salt: Add flaky sea salt after baking for the best flavor burst!
- Use Quality Ingredients: Premium chocolate and fresh pretzels make a world of difference.
- Switch to a Spatula: Use a sturdy spatula to fold in the ingredients rather that a whisk or hand mixer. It helps to keep the batter from getting too dense and over-mixed.
- Don't Over-bake: The cookie should be slightly underdone in the center when you pull it from the oven. It will continue to bake as it cools.

The Ingredient List
- All-Purpose Flour: The backbone of any great cookie. I like using a classic all purpose flour for baking. It's versatile and very reliable.
- Butter: Room temperature butter creates that perfect balance of crispy edges and a soft, gooey center.
- Light Brown Sugar: Adds depth and richness while keeping the cookie irresistibly chewy.
- White Sugar: Balances the molasses notes from the brown sugar for a well-rounded sweetness.
- Vanilla Extract: A splash of vanilla ties all the flavors together. Trust me, it's the secret to any easy cookie recipe.
- Chocolate-Covered Salty Pretzels: These bring the salty crunch that contrasts beautifully with the sweet elements.
- Peanut Butter Pieces: No one says no to peanut butter in a cookie. We use those classic peanut butter pieces in this cookie skillet.
- M&M's: The colorful, gooey chocolate addition makes this cookie next-level.

Step by Step Instructions

Mix the Wet Ingredients
Preheat your oven to 375º and grease your cast iron skillet with butter or cooking spray. This ensures your cookie doesn't stick and slides out like a dream.
Combine light brown sugar and white sugar with butter until it's fluffy and pale. This step is crucial for that soft texture. Mix in eggs and vanilla extract. Whisk until smooth to avoid any lumps.

Combine the Dry Ingredients & Chocolate
Slowly fold in all-purpose flour, baking powder, baking soda, and salt. Overmixing can toughen your cookie, so mix until just combined.
Toss in the pretzel pieces, M&M's, and peanut butter chip mix-ins. Stir gently to distribute evenly.

Press into the Skillet
Pour the cookie dough into your skillet, press it into an even layer, and sprinkle extra goodies on top of the cookie.

Bake, Cool, and Serve
Bake until golden brown and slightly underdone in the center-it'll continue cooking as it cools.
Let your cookie rest for 5-10 minutes before digging in. For those with a sweet tooth, top it with a scoop of vanilla ice cream.

Frequently Asked Questions
Can I use a different type of skillet?
Absolutely! While a cast iron skillet gives the best texture, an oven-safe non-stick pan works too.
How do I store leftovers?
Cover your skillet with foil or plastic wrap and store at room temperature for up to 3 days. Reheat in the oven for a fresh-out-of-the-oven experience.
Can I freeze the dough?
Yes! Shape the dough into a disc, wrap it tightly in a freezer bag, and freeze for up to 2 months. Bring the dough to room temperature before adding to the oven to bake.
