What Ingredients You Will Need

This peanut butter cup s’mores skillet cookie recipe keeps things simple but packs a punch with every ingredient. Most of these are basic pantry finds, plus a few special additions for that iconic s’mores flavor. Here’s what you’ll need:

• For the Cookie Dough:
  • 1/2 cup (113g) unsalted butter, softened (adds richness and that classic cookie flavor)
  • 1/2 cup (100g) light brown sugar, packed (gives the cookie that chewy center and caramel notes)
  • 1/4 cup (50g) granulated sugar (balances the brown sugar and helps with that golden edge)
  • 1 large egg, room temperature (helps bind everything and gives lift)
  • 1 tsp vanilla extract (for warmth and depth—I use Nielsen-Massey, but any pure extract works)
  • 1 cup (120g) all-purpose flour (classic base—for gluten-free, swap with a 1:1 GF blend)
  • 1/2 cup (45g) graham cracker crumbs (crushed fine—for that true s’mores vibe; use gluten-free grahams if needed)
  • 1/2 tsp baking soda (for just the right rise)
  • 1/4 tsp salt (balances all the sweetness)
  • 3/4 cup (130g) semi-sweet chocolate chips (use mini chips for better distribution)
• For the S’mores Layers and Topping:
  • 8-10 mini peanut butter cups (such as Reese’s, unwrapped and halved; use dairy-free if needed)
  • 1 cup (40g) mini marshmallows (the star of the show—don’t skimp!)
  • 2 graham crackers, broken into pieces (adds crunch and classic flavor)

If you want to get fancy with your peanut butter cup s’mores skillet cookie, try adding a handful of chopped dark chocolate or swapping in white chocolate chips. For an allergy-friendly version, sunflower seed butter cups are a great substitute. And if you prefer a less sweet cookie, go for bittersweet chips instead of semi-sweet.

For summer, I’ll sometimes toss in a handful of fresh raspberries (seriously, try it!) for a tart twist. And don’t be afraid to use whatever chocolate you love most—milk, dark, or even caramel-filled. The beauty of this recipe is how forgiving and customizable it is. Just promise me you won’t skip the marshmallows—they’re what make this skillet cookie pure gooey magic.

Equipment Needed

• 10-inch cast iron skillet (my personal favorite for even baking and that crispy edge—Lodge and Staub are solid picks, but any oven-safe skillet will do)
• Mixing bowls (one for wet, one for dry ingredients; nothing fancy needed)
• Hand mixer or sturdy whisk (hand mixer gives a fluffier dough, but you can totally make this with a wooden spoon and elbow grease—been there!)
• Silicone spatula (for folding in chocolate and scraping every bit of dough)
• Measuring cups and spoons (accuracy matters—especially for baking)
• Oven mitts (the skillet gets super hot, so don’t skip these!)

If you don’t have a cast iron skillet, you can use any oven-safe pan or even a deep-dish pie plate. Just keep an eye on bake time—glass and ceramic can take a few minutes longer. I once tried this in a square brownie pan, and while it worked, you don’t get those crispy edges like you do with cast iron. As for cleaning, a quick soak and a gentle scrub (no harsh soap on cast iron, please!) keeps your skillet in top shape. If you’re on a budget, thrift stores are gold mines for cast iron—just season them well before using.

How to Make Peanut Butter Cup S’mores Skillet Cookie

1. Preheat the Oven and Prep the Skillet:
   
   Preheat your oven to 350°F (175°C). Lightly grease a 10-inch cast iron skillet with a thin layer of butter or neutral oil. (If your skillet is well seasoned, you can skip the butter.) This helps prevent sticking and gives you that beautiful golden crust.
2. Cream the Butter and Sugars:
   
   In a large mixing bowl, beat together 1/2 cup (113g) softened unsalted butter, 1/2 cup (100g) light brown sugar, and 1/4 cup (50g) granulated sugar until light and fluffy—about 2-3 minutes if using a mixer, or a bit longer by hand. The mixture should look pale and creamy. (If your butter isn’t quite soft, microwave it for 10 seconds. Just don’t melt it!)
3. Add the Egg and Vanilla:
   
   Crack in 1 large egg and stir in 1 tsp vanilla extract. Beat until fully combined. The dough will look smooth and glossy at this point (and will smell amazing!).
4. Mix the Dry Ingredients:
   
   In a separate bowl, whisk together 1 cup (120g) all-purpose flour, 1/2 cup (45g) graham cracker crumbs, 1/2 tsp baking soda, and 1/4 tsp salt. Gradually add the dry ingredients to the wet, mixing on low speed or by hand until just combined. Don’t overmix—stop when no streaks of flour remain.
5. Fold in the Chocolate Chips:
   
   Using a spatula, gently fold in 3/4 cup (130g) semi-sweet chocolate chips. The dough will be thick and a little sticky—a good sign!
6. Press Dough into Skillet & Layer the Goodies:
   
   Scoop about two-thirds of the cookie dough into your prepared skillet. Press it into an even layer, making sure to get all the way to the edges. Arrange half of your peanut butter cup halves and a third of the mini marshmallows over the dough. Dot with a few broken graham cracker pieces.
7. Add Remaining Dough & Top:
   
   Gently dollop the remaining cookie dough on top and spread it out (it’s okay if some marshmallows and peanut butter cups peek through). Scatter the rest of the peanut butter cups, mini marshmallows, and more graham cracker pieces over the top.
8. Bake:
   
   Bake at 350°F (175°C) for 20-25 minutes, or until the edges are golden and the center looks just set. The cookie will puff up slightly and the marshmallows will start to toast. (If you like a gooier center, bake closer to 20 minutes; for a firmer cookie, go for 25.) If desired, turn on the broiler for 1-2 minutes at the end to get those marshmallows extra toasty—but watch closely!
9. Cool Briefly & Serve:
   
   Let the skillet cookie cool for 5-10 minutes. The center will finish setting and everything will be perfectly gooey. Grab some spoons and dig in while it’s still warm—or, if you have more patience than I do, slice into wedges and serve with ice cream.

Troubleshooting Tips: If your cookie seems greasy, double-check your butter measurement and be sure you’re not using melted butter. If the edges brown too quickly, tent the skillet with foil for the last 5 minutes. And don’t panic if the marshmallows puff up a lot—they’ll settle as the cookie cools.

Personal tip: I always sneak a few extra peanut butter cups on top in the last five minutes of baking. They get perfectly melt-y and look so tempting!

Cooking Tips & Techniques

• Don’t Overmix: Once you add the dry ingredients, mix just until combined. Overworking the dough can make it tough instead of soft and chewy.
• Watch the Marshmallows: Under the broiler, marshmallows can go from golden to burnt in a flash. Keep the door cracked and don’t walk away!
• Temperature Matters: Let your egg come to room temperature before mixing. Cold eggs can seize up the butter and affect the final texture.
• Customize the Gooey Factor: If you like a softer, more molten center, pull the skillet cookie out right as the edges set. For a sliceable cookie, bake a couple minutes longer.
• Serve Warm: The cookie is at its absolute best warm from the oven. If you need to reheat, pop it back in the oven for 5-7 minutes at 300°F (150°C) to revive the gooey magic.

One mistake I made early on was using too many marshmallows in the middle—they melted away and left a gap! Sprinkling them on top gives you that perfect toasted look and keeps the center intact. I’ve also learned that a light layer of butter in the skillet gives you the best crust and helps with cleanup later.

Multitasking tip: While the cookie bakes, set up your movie and prep your favorite snacks. That way, everything’s ready when dessert comes out of the oven (and you can eat it while it’s still warm and gooey!).

Variations & Adaptations

• Gluten-Free: Swap the all-purpose flour and graham crackers for your favorite 1:1 gluten-free blend and gluten-free grahams. I’ve made it this way for friends, and it’s always a hit.
• Vegan Option: Use plant-based butter, a flax egg (1 tbsp ground flax + 2.5 tbsp water), dairy-free chocolate chips, vegan marshmallows, and vegan peanut butter cups. It turns out just as gooey and delicious!
• Flavor Twists: Try almond butter cups, add a handful of chopped walnuts, or mix in butterscotch chips for something unexpected. For a fruity spin, scatter a handful of raspberries on top before baking.

To make this peanut butter cup s’mores skillet cookie in individual portions, scoop dough into 6-8 mini skillets or ramekins and bake for 12-15 minutes. It’s a fun way to give everyone their own personal treat (and no sharing required!).

Personally, I love making a “dark chocolate lovers” version with 70% cacao chips and extra dark peanut butter cups. The bittersweet chocolate balances the marshmallows perfectly, and it’s a little less sweet for grown-up taste buds.

Serving & Storage Suggestions

Serve your peanut butter cup s’mores skillet cookie warm, straight from the skillet—you can dig in with spoons, family-style, or slice into wedges for more formal occasions. Top with a scoop of vanilla ice cream or a drizzle of chocolate sauce if you really want to go all out. I love pairing it with strong coffee or a cold glass of milk (classic, right?).

Got leftovers? Cover the cooled skillet tightly with foil or transfer slices to an airtight container. Store at room temperature for 2 days, or in the fridge for up to 5 days. For longer storage, wrap portions and freeze for up to 2 months. To reheat, pop slices in a 300°F (150°C) oven for 5-7 minutes, or microwave individual wedges for 10-15 seconds (just until warm!).

The flavors actually deepen and meld overnight, making leftovers almost as irresistible as the first day. If you somehow resist eating it all at once, you’ll be rewarded with a perfectly chewy, slightly fudgy cookie the next day.

Nutritional Information & Benefits

Each serving (about 1/8th of the skillet) is estimated at 350-400 calories, with 5-6g protein, 18g fat, and 35g carbs. The peanut butter cups add protein and healthy fat, while dark chocolate chips offer antioxidants. If you use whole wheat or a gluten-free flour, you’ll get a bit more fiber.

Be mindful—this recipe contains peanuts, wheat, eggs, and dairy. For those with allergies, the swaps above will keep it safe and just as tasty. I personally find this dessert so satisfying that a small portion hits the spot, and it’s less processed than many store-bought treats.

While it’s definitely an indulgence, the homemade aspect means you control the ingredients. And honestly, a little joy now and then is its own kind of wellness!

Conclusion
