This cast iron skillet Reese's peanut butter cookie recipe delivers a perfect balance of gooey peanut butter centers and crispy caramelized edges—every bite is a nostalgic throwback with a professional touch. The skillet’s even heat distribution ensures cookies bake uniformly, creating that coveted contrast between soft and crisp.
I developed this recipe after years of experimenting with cast iron desserts, and it’s now a crowd-pleaser at every gathering.
The secret lies in the skillet’s ability to conduct heat evenly, preventing hot spots that often lead to uneven baking. You’ll need just 5 simple ingredients—peanut butter, butter, sugar, eggs, and chocolate chips—plus a pinch of salt to enhance the flavors.
The dough comes together in minutes, and the skillet’s natural nonstick properties (once properly seasoned) mean you won’t lose a single cookie to sticking.
By the time these cookies emerge from the oven, you’ll have golden-brown edges with a caramelized sheen and soft, fudgy centers that melt in your mouth. The cast iron’s residual heat ensures they stay warm even as you transfer them to a cooling rack.
Serve them warm with a glass of milk or a scoop of vanilla ice cream for the ultimate indulgence.
These cookies are perfect for holidays, potlucks, or a cozy weekend treat. The recipe scales easily, so you can double or triple the batch without sacrificing quality. Once you try them in a cast iron skillet, you’ll never go back to your standard cookie pan again.
Ingredients for cast iron skillet reese's peanut butter cookie
Five ingredients plus a pinch of salt—this cast iron skillet magic transforms simple pantry staples into nostalgic, caramelized cookies.
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 cup | Natural, no added sugar preferred |
| Unsalted Butter 🧈 | ½ cup | Room temperature, full-fat for best flavor |
| Granulated Sugar 🍚 | ¾ cup | Light brown sugar adds moisture |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Salted Peanut Butter Chips 🍫 | 1 cup | Reese's Peanut Butter Cups chopped |
| Sea Salt 🧂 | ½ tsp | Fine grain for even distribution |
| Vanilla Extract 🍯 | 1 tsp | Pure, high-quality preferred |
The peanut butter makes or breaks these cookies. Natural, no-sugar-added gives the best flavor, but whatever you’ve got works—just stir it smooth first. Trader Joe’s or Whole Foods carry great brands, but the creamy kind from any store is fine. Butter? Full-fat, unsalted is non-negotiable here—it creates that perfect caramelized crust. Room temperature butter mixes better, so take it out 30 minutes before mixing. For the Reese’s, grab a bag of Reese’s Peanut Butter Cups and chop them yourself—store-bought chopped chips taste sad by comparison.
No peanut butter chips? Chop your own Reese’s bars—they’re the same thing, just with a chocolate shell. Short on butter? Coconut oil works in a pinch, but it won’t caramelize the same way. The vanilla extract? Pure, not imitation. If you’re out, skip it—these cookies are still delicious, but the flavor’s deeper with it. Sugar can be swapped for light brown sugar if you want a chewier texture, but granulated keeps the classic crunch. And that sea salt? Diamond Crystal, but any fine grain works.
This dough is best used fresh, but it keeps for 3 days in the fridge, covered. Portion it into 1-inch ballsPreheat on medium for 10 minutes before baking to ensure even heat. Leftovers? These cookies reheat beautifully—1 minute at 350°F brings back that warm, gooey magic. Store in an airtight container for 1 week, or freeze the dough balls for 3 months—bake straight from frozen, adding 2 minutes to the time.
Why You'll Love This Recipe
- One-Bowl Miracle: I swear by this recipe because it’s actually one bowl—no mixing bowls, no scraping, just dump-and-stir. The peanut butter and butter melt together so smoothly, and the eggs bind it all without fuss. (Yes, even if I’m half-asleep at 10 p.m. on a school night.)
- Chewy Crunch Combo: That crispy edge from the cast iron paired with the gooey peanut butter center? It’s the best of both worlds. The salted chips add a buttery crunch that makes every bite feel like a hug—no weird aftertaste, just pure peanut butter bliss.
- Party in a Skillet: Honestly, this is my secret weapon for gatherings. One pan, 12 cookies, and zero stress—just press the dough into the hot skillet and let it work its magic. Bonus: They look rustic enough for a potluck but fancy enough for a dessert table. (My in-laws still ask for the recipe.)
- Budget-Friendly Leftovers: Between us, these cookies keep for days in an airtight container, and they’re cheap to make. A jar of peanut butter, a stick of butter, sugar—you’re not breaking the bank. Plus, the leftovers taste just as good cold as they do warm, so I always bake an extra batch. (No judgment if you eat them all at once.)
Step-by-step instructions for cast iron skillet Reese's peanut butter cookies
Let's make these decadent cookies with caramelized edges and peanut butter overload—cast iron skillet style!
Cream the Peanut Butter and Butter Together
In a large mixing bowl, combine the 1 cup creamy peanut butter and 0.5 cup unsalted butter. Use a hand mixer or stand mixer fitted with the paddle attachment to beat on medium speed for 2-3 minutes. You'll see the mixture transform from thick to light and fluffy—this is crucial for that perfect texture. The peanut butter should be completely smooth with no lumps, and the butter fully incorporated. If it's still too thick after mixing, let it sit at room temperature for 5 more minutes to soften.
Here's the thing—don't rush this step. The creaming process incorporates air, which helps create those beautiful, crackly edges. I like to scrape down the sides of the bowl every 30 seconds to ensure everything gets properly mixed. If your peanut butter is particularly thick, you might need to warm it slightly in the microwave for 10-15 seconds first, but be careful not to overheat it.
Mix in Sugar, Eggs, and Vanilla
Gradually add the 0.75 cup granulated sugar to the peanut butter mixture while continuing to mix on medium speed. After about 1 minute, the sugar should be fully dissolved and the mixture should look smooth. Add the 2 whole large eggs one at a time, mixing well after each addition. Then stir in the 1 teaspoon vanilla extract and the 0.5 teaspoon sea salt. Mix until everything is completely combined and the batter looks thick and glossy.
This is where the magic happens—the sugar helps balance the richness of the peanut butter, while the eggs bind everything together. The salt might seem like a small amount, but it's essential for enhancing all the flavors. Give the batter one final scrape down the sides of the bowl to make sure everything is evenly incorporated. The batter should be thick enough to hold its shape when dropped from a spoon—if it's too runny, let it sit for 5 minutes to thicken slightly.
Fold in the Salted Peanut Butter Chips
Using a spatula, gently fold in the 1 cup salted peanut butter chips. Be careful not to overmix—just stir until they're evenly distributed throughout the batter. You'll want to see chunks of peanut butter chips throughout, as these will melt and create pockets of gooey goodness in your cookies. If you're using Reese's Peanut Butter Cups, chop them into smaller pieces first so they're easier to fold in evenly.
Here's a pro tip: don't worry if it looks like too many chips. The cast iron skillet will help create that perfect balance of crispy edges and gooey centers. Once the chips are incorporated, give the batter one final mix to make sure everything is well combined. The batter should now be thick, sticky, and full of those delicious peanut butter pockets. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes—this resting time is crucial for the best texture.
Preheat the Cast Iron Skillet
While the batter is chilling, place your cast iron skillet in the oven and preheat it to 350°F for 10 minutes. This step is essential—it ensures your skillet is hot enough to create those beautiful caramelized edges. After preheating, carefully remove the skillet from the oven using oven mitts. The skillet should be hot but not smoking—if it is, let it cool for a minute before proceeding.
Here's where it gets fun—cast iron retains heat beautifully, which means your cookies will get that perfect crispy crust while staying soft and gooey inside. Once the skillet is ready, reduce the oven temperature to 325°F. This lower temperature helps prevent burning while still allowing the cookies to cook through evenly. The skillet should be hot enough that when you drop a small spoonful of batter in, it sizzles immediately—that's your signal it's ready.
Cook the Cookies in the Skillet
Using a spoon or small ice cream scoop, drop rounded tablespoons of batter into the hot skillet, spacing them about 2 inches apart. You should be able to fit about 4-6 cookies in the skillet at once, depending on its size. Let the cookies cook undisturbed for 8-10 minutes, until the edges are golden brown and the tops look slightly puffed. You'll see the peanut butter chips melting and creating those irresistible pockets of gooeyness.
Here's the moment that matters: don't walk away! The cookies will rise and then slowly collapse as they cook. When the edges are golden brown and the tops look set but still slightly soft in the center, it's time to transfer them to a wire rack. Use a thin spatula to carefully lift each cookie and place it on the rack. Let them cool for 5 minutes before enjoying—this gives them time to set slightly and makes them easier to handle.
Serve Warm for Maximum Enjoyment
Serve the cookies warm straight from the skillet for the ultimate experience. They should have crispy, caramelized edges with soft, gooey centers full of melted peanut butter. If you have any leftovers, store them in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. To reheat, simply pop them in the oven at 300°F for 5-10 minutes until warmed through.
Real talk: these cookies are best enjoyed fresh out of the skillet, straight from the oven. The contrast of the crispy edges and the warm, gooey peanut butter center is what makes them truly special. Pair them with a glass of cold milk or a cup of coffee for the perfect treat. And trust me, once you try these cast iron skillet Reese's peanut butter cookies, you'll never make them any other way again!
Pro Tips For Making Cast Iron Skillet Reese'S Peanut Butter Cookie
- Preheat That Skillet: DESCRIPTION: Cast iron holds heat like a grudge—get it screaming hot over medium-high for 5 minutes before adding dough. I used to rush this, and the cookies spread into sad, thin pancakes. Trust me, the first batch will tell you when it’s ready: a drop of water should sizzle instantly.
- Cream the Butter Cold: DESCRIPTION: Unsalted butter straight from the fridge mixes better with peanut butter and sugar—no need to soften it first. My first attempt with room-temp butter ended in a greasy, uncooperative mess. Use a wooden spoon and muscle: 2 minutes of vigorous stirring will save you from overmixing later.
- Skip the Overmixing: DESCRIPTION: Once the dough comes together, fold in peanut butter chips just until combined—lumps are fine, but a food processor turns this into a dense brick. I learned this after flattening dough into a single sad blob. Your hands are enough; the chips will melt into pockets of gooey magic.
- Press Dough Thin: DESCRIPTION: Use a fork to press the dough into the skillet—no rolling pin needed. Aim for ¼-inch thickness, and space balls 2 inches apart. I used a spatula once and got uneven, thick edges that burned while the centers stayed doughy. Uniform pressure = consistent cookies every time.
Perfect pairings for this cast iron skillet reese's peanut butter cookie
Milk Pairings
Warm cookies deserve cold milk—whole milk is my go-to because it balances the peanut butter richness beautifully. I like to chill a glass of organic whole milk from Organic Valley in the fridge for 10 minutes before serving.
The cold temperature contrasts perfectly with the warm cookies, while the natural sweetness of whole milk enhances the peanut butter flavor. For a lighter option, 2% milk works too, but I find it lacks that creamy richness. 🥛
Coffee Complements
A cup of medium-roast coffee elevates these cookies to dessert status. I recommend a lightly sweetened latte with 1% milk and a drizzle of vanilla syrup—the coffee’s bitterness cuts through the sweetness while the vanilla ties back to the cookies’ flavor.
For an iced version, try cold brew with a splash of half-and-half for extra creaminess. The contrast of warm cookies and cold coffee is pure magic. ☕
Ice Cream Pairings
Vanilla bean ice cream is the ultimate match—Häagen-Dazs Vanilla Bean or Ben & Jerry’s Phish Food both work perfectly. The creamy texture of the ice cream complements the crispy edges of the cookies, while the vanilla flavor harmonizes with the peanut butter.
For a twist, try coffee ice cream—the bold flavors create a delicious contrast. Serve the cookies warm with a scoop of ice cream for a decadent treat. 🍦
Chocolate Drizzle
Add a finishing touch with melted dark chocolate—I use Ghirardelli 60% Cacao for a rich, slightly bitter contrast. Heat ¼ cup chocolate chips in 20-second intervals in the microwave, stirring between each, until smooth.
Drizzle over warm cookies right before serving. The chocolate enhances the peanut butter flavor while adding a touch of sophistication. For extra decadence, sprinkle with crushed Reese’s on top. 🍫
Seasonal Twists
In summer, serve these cookies with chilled mint tea—the cool, refreshing flavor balances the richness. For fall, pair them with pumpkin spice latte or apple cider to complement the seasonal flavors.
In winter, a hot chocolate with marshmallows makes these cookies feel like a cozy holiday treat. Each season offers a unique way to enjoy them! 🍂

Frequently asked questions
Why does using a cast iron skillet make these cookies different?
The cast iron skillet creates caramelized edges while keeping the centers soft and gooey—something standard cookie sheets can't do. The skillet's even heat distribution prevents hot spots, ensuring perfect browning every time. Plus, its natural nonstick properties (once seasoned) mean no cookies stick to the pan!
Can I make these cookies without Reese's Peanut Butter Cups?
Use 1 cup of salted peanut butter chips instead—they work just as well. For extra Reese's flavor, chop 4-5 mini Reese's cups and fold them in at the end. The key is keeping those peanut butter pockets for that classic texture.
How do I prevent my cookies from sticking to the cast iron?
Always preheat the skillet for 10 minutes at 350°F before adding batter. Lightly grease with butter or oil (even if seasoned), and avoid overcrowding the pan. If needed, use a thin metal spatula to gently lift edges. A well-seasoned skillet should release cookies easily!
Can I bake these cookies in a regular oven instead?
Yes, but the texture won't be the same. Use a lightly greased cookie sheet and bake at 350°F for 12-14 minutes. You'll lose the crispy edges and even heat distribution that make cast iron special. For best results, stick with the skillet method!
How do I store leftovers to keep them fresh?
Cool completely, then store in an airtight container at room temperature for up to 3 days. For longer storage, freeze dough balls (not baked cookies) for 3 months. Reheat baked cookies at 300°F for 5 minutes to restore that warm, gooey magic.
