Easy Giant Christmas Skillet Cookie
The Ultimate Holiday Dessert: No Chilling, No Rolling, Just One Giant Cookie
The holiday season is filled with endless baking projects, and while there is a time and place for intricately decorated cut-out cookies, sometimes you just want something incredibly warm, gooey, and effortless. Enter the giant Christmas skillet cookie. If you have ever felt exhausted by the prospect of chilling dough, rolling it out, and swapping baking sheets in and out of the oven, this cast iron dessert is about to become your new best friend.
Often referred to as a “pizookie” (a pizza cookie), this massive, shareable treat offers the absolute best texture you could ever want in a baked good. Because it is baked directly in a hot cast iron skillet, the edges become beautifully golden, buttery, and crispy, while the center remains incredibly soft, warm, and fudge-like. Every single bite is loaded with melty chocolate chips and festive red and green M&Ms, making it a stunning centerpiece for your dessert table.
This is the kind of dessert that brings people together. You can serve it straight out of the warm pan, plop a few scoops of vanilla ice cream right in the middle, and hand everyone a spoon. It takes only ten minutes to throw the dough together, requires zero chilling time, and bakes up into a show-stopping treat that your family will be fighting over.
Why You’ll Love This Recipe
- Zero chilling required: Unlike traditional chocolate chip cookies, you do not have to wait for this dough to chill. It goes straight from the mixing bowl into the oven.
- No rolling or scooping: You completely skip the tedious process of portioning out individual cookies and baking in multiple batches.
- The perfect texture: The cast iron pan creates irresistible crispy, caramelized edges while keeping the center incredibly soft and gooey.
- Festive and fun: The red and green holiday candies make it instantly festive, perfect for Christmas Eve movie nights or holiday parties.
- Quick cleanup: You only need one mixing bowl and one skillet, which means you won’t be washing a mountain of dishes afterwards.
Ingredients
- Unsalted butter: Melted and slightly cooled. Using melted butter is the secret to a chewy, brownie-like texture rather than a cakey one.
- Light brown sugar: Packed tightly. The molasses in the brown sugar provides deep flavor and incredible moisture.
- Granulated sugar: Adds just the right amount of sweetness and helps create those coveted crispy edges.
- Large egg + egg yolk: You need one whole egg for structure, plus an extra egg yolk to make the cookie center extra rich and fudgy. Ensure they are at room temperature.
- Vanilla extract: A generous splash enhances the butter and chocolate flavors perfectly.
- All-purpose flour: Gives the cookie its structure. Be sure to spoon and level your flour so the dough isn’t too dry.
- Baking soda: The leavening agent that gives the cookie a slight lift so it doesn’t become too dense.
- Salt: A necessary addition to cut through the sweetness and elevate the flavors.
- Semi-sweet chocolate chips: The classic choice for a rich, melty chocolate profile that isn’t overly sweet.
- Red and green M&Ms: Adds a wonderful candy crunch and that signature holiday cheer.
Step-by-Step Instructions
Step 1: Prep the Oven and Skillet
Start by preheating your oven to 350°F (175°C). Grab your trusty 10-inch cast iron skillet and lightly grease the inside with a little bit of butter or non-stick baking spray. Even though cast iron is naturally non-stick when well-seasoned, a little extra insurance guarantees your cookie will slice cleanly later.
Step 2: Whisk the Wet Ingredients
In a large mixing bowl, pour in your melted (and slightly cooled) unsalted butter, the packed light brown sugar, and the granulated sugar. Use a whisk to vigorously beat them together until the mixture looks smooth, glossy, and well-combined. There should be no lumps of brown sugar remaining.
Step 3: Add the Eggs and Vanilla
To your sugar and butter mixture, add the whole room-temperature egg, the extra egg yolk, and the vanilla extract. Whisk everything together for about a minute. The batter will lighten slightly in color and become beautifully smooth.

Step 4: Mix in the Dry Ingredients
Put your whisk away and grab a rubber spatula. Sprinkle the all-purpose flour, baking soda, and salt directly over the wet ingredients. Gently fold the dry ingredients into the wet mixture. Stop mixing the very second you no longer see any dry streaks of white flour. Overmixing at this stage will overwork the gluten and result in a tough cookie.
Step 5: Fold in the Chocolate and Candies
Pour the semi-sweet chocolate chips and the festive red and green M&Ms into the cookie dough, making sure to reserve a small handful of both to decorate the top later. Gently fold the candies and chocolate into the dough until they are evenly distributed.

Step 6: Press into the Skillet
Transfer the thick cookie dough directly into your prepared cast iron skillet. Use your hands or your rubber spatula to press the dough out into an even layer, making sure it reaches all the edges of the pan. Take your reserved chocolate chips and M&Ms and gently press them into the top of the dough so it looks picture-perfect when it comes out of the oven.
Step 7: Bake and Rest
Place the skillet in the center of your preheated oven and bake for 25 to 30 minutes. You want the edges to be deeply golden brown and pulling away slightly from the sides of the pan. The center should look just barely set—it might even look a tiny bit undercooked. This is exactly what you want! The heavy cast iron retains a massive amount of heat, so the cookie will continue to bake as it rests. Let it cool in the pan for at least 15 minutes before serving so it sets up enough to slice or scoop.

Expert Cooking Tips
- Use the extra egg yolk: Do not skip the extra yolk! Because we are using melted butter instead of creamed butter, the extra fat from the egg yolk binds the dough and guarantees a dense, gooey, chewy center.
- Cool the melted butter: If your melted butter is piping hot when you add the sugars and eggs, it can scramble the eggs or melt your chocolate chips too early. Let it sit for 5-10 minutes after melting.
- Do not overbake: To achieve that iconic “pizookie” texture, pull the skillet from the oven while the center still looks slightly soft. It will firm up beautifully as it rests on the counter.
- Serve it warm: Skillet cookies are meant to be enjoyed warm! The 15-minute resting period is crucial so you don’t burn your mouth, but it allows the chocolate to remain perfectly molten.
Variations to Try
- Peppermint Crunch: Swap the holiday M&Ms for crushed candy canes or peppermint crunch baking chips for a festive, minty twist.
- Peanut Butter Lovers: Swirl half a cup of creamy peanut butter into the dough right before pressing it into the skillet, and use Reese’s Pieces instead of M&Ms.
- White Chocolate Macadamia: Skip the semi-sweet chips and use white chocolate chips and toasted macadamia nuts for a richer flavor profile.
- Salted Caramel: Drizzle the warm, freshly baked skillet cookie with high-quality salted caramel sauce and a sprinkle of flaky sea salt right before serving.
What to Serve With a Giant Christmas Skillet Cookie
This massive, warm cookie is essentially begging for toppings. For the ultimate dessert experience, serve it straight from the pan with:
- Several generous scoops of premium vanilla bean or peppermint ice cream.
- A heavy drizzle of hot fudge or warm chocolate ganache.
- Freshly whipped cream.
- A tall, ice-cold glass of milk or a mug of rich hot cocoa.
Storage & Reheating
Refrigerator
If you happen to have leftovers, tightly wrap the fully cooled skillet cookie (or transfer the slices to an airtight container) and store it in the refrigerator for up to 4 days.
Freezer
You can slice the baked, cooled skillet cookie into wedges and freeze them in a freezer-safe zip-top bag for up to 2 months. You can also freeze the raw cookie dough tightly wrapped in plastic; simply let it thaw overnight in the fridge before pressing it into your skillet.
Reheating
To bring back that fresh-from-the-oven warmth, microwave individual slices for about 15-20 seconds. If you want to reheat the entire skillet, place it in a 300°F (150°C) oven for about 5-8 minutes until warmed through.
Frequently Asked Questions
Can I make this if I don’t have a cast iron skillet?
Yes! While cast iron yields the best crispy edges, you can bake this in a standard 9×9-inch square baking dish or a 9-inch round cake pan. If using a lighter metal or glass pan, keep a close eye on the baking time, as it may bake slightly faster and the edges won’t be quite as crispy.
Why do I have to use melted butter instead of softened butter?
Melted butter is the key to creating a chewy, brownie-like texture. Creaming softened butter incorporates air into the dough, which would result in a cake-like, puffy skillet cookie. Melting the butter keeps the dough dense and rich.
Can I prepare the dough ahead of time?
Absolutely. You can mix the dough completely, press it into your cast iron skillet, cover it tightly with plastic wrap, and leave it in the refrigerator for up to 2 days before baking. If baking straight from the fridge, you may need to add 2-3 extra minutes to the baking time.
Why did my cookie sink in the middle?
A slight dip in the center is actually normal and desired for a skillet cookie—it means the center is fudgy! However, if it sank drastically, you may have underbaked it slightly too much, or your baking soda might be expired.
How do I clean my cast iron skillet after making this?
Once the skillet is empty and mostly cooled, wash it with warm water and a gentle sponge. Avoid harsh soaps. Dry it completely on the stovetop over low heat, then rub a very light layer of cooking oil into the pan to protect the seasoning before putting it away.

Notes
The secret to chewiness: Don't skip the extra egg yolk or swap the melted butter for softened butter; these are the keys to a dense, chewy center. Don't overbake: The center will look slightly soft when you pull it out at 25-30 minutes, but the residual heat from the cast iron will finish baking it on the counter. Make Ahead: You can press the dough into the skillet, cover it, and keep it in the fridge for up to 2 days before baking. Pan Substitute: If you don't have a cast iron skillet, a 9-inch round baking pan or 9x9 square dish will work, though the edges may not get as crispy.
