This peanut butter cookie with Reese's pieces recipe combines my two favorite childhood indulgences into one irresistible treat. ✨ The secret lies in balancing creamy peanut butter with rich chocolate chunks, creating cookies that are perfectly fudgy with pockets of melty Reese's in every bite—just like my dad's infamous chocolate chip cookies, only better.
I developed this recipe after years of testing, ensuring the dough stays thick enough to hold those chocolatey surprises without falling apart.
The process is straightforward but requires precision: mixing the dough at room temperature prevents cracking, while baking at a precise 350°F ensures a golden exterior with a soft, gooey center.
The addition of Reese's pieces in the final dough fold guarantees they stay intact during baking, delivering that signature crunch and sweetness with every bite. This recipe yields about 24 cookies, perfect for sharing or satisfying a serious sweet tooth.
What sets these apart is the texture—thick enough to hold shape but tender enough to melt in your mouth, with just the right amount of peanut butter richness balanced by the chocolatey crunch.
The aroma of baking peanut butter fills the kitchen, and the moment those cookies emerge from the oven, still warm and fragrant, is pure comfort food magic. Trust me, once you try these, you'll never go back to store-bought again.
These cookies are ideal for holiday gifting, bake sales, or simply treating yourself after a long week. Pair them with a glass of cold milk for the full experience, or save a few to enjoy the next morning with your coffee.
The dough can even be chilled for up to 48 hours, making them perfect for meal prep. Let's get baking!
Ingredients for peanut butter cookie with reese's pieces
Peanut butter and chocolate magic—just 11 ingredients for cookies that taste like nostalgia.
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 cup | Natural, unsweetened preferred |
| Granulated Sugar 🍚 | ¾ cup | White or light brown |
| Packed Brown Sugar 🍚 | ¾ cup | Dark brown for extra flavor |
| Large Eggs 🥚 | 2 whole | Room temperature for mixing |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for easier mixing |
| Vanilla Extract 🌿 | 1 ½ tsp | Pure, high-quality extract |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Baking Soda 🧂 | ½ tsp | Freshly measured |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Reese's Pieces 🍫 | 1 ½ cups | Miniature, not regular |
| Semisweet Chocolate Chunks 🍫 | ½ cup | High-quality, 1-inch pieces |
The peanut butter is non-negotiable here. Jif Natural or Smucker's Creamy (no sugar added) work best—they stay creamy without graininess. If you grab the powdered kind, add 1 tbsp oil to compensate. The sugars are key: light brown for chewiness, white for crisp edges. I always buy Domino brand flour—it's reliable for baking. For the Reese's, miniature pieces are a must (the regular ones get too big and don't melt evenly). The chocolate chunks? Ghirardelli or Guittard make a difference—avoid the dollar-store stuff.
No peanut butter? Almond butter works in a pinch, but the flavor changes. Short on brown sugar? Substitute white sugar plus 1 tsp molasses for depth. The butter must be cold—if it melts during mixing, the dough gets greasy. For chocolate lovers, swap half the Reese's for white chocolate chunks. Fresh vanilla extract is worth the splurge—imitation smells like perfume. The dough gets thick, so don't overmix (it's okay if it looks lumpy). If your kitchen's hot, chill the dough 30 minutes before baking.
The dough keeps for 48 hours in the fridge, wrapped tightly. For extra flavor, let it rest overnight—the peanut butter develops more richness. Baked cookies stay fresh 5 days in an airtight container, but they won't last that long. Freeze portions for 3 months—just thaw at room temp. Pro tip: Underbake by 1 minute for gooey centers. These reheat beautifully in the oven at 300°F for 5 minutes—perfect for a midnight snack.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this—just a fork and your hands. Creamy peanut butter and softened butter get mashed together in seconds, then the brown sugar and egg come in to play. No electric appliances, no fuss, just dough that comes together faster than you can say "Reese’s pieces."
- Double Chocolate-Peanut Magic: That first bite? Crunchy Reese’s pockets melting into warm peanut butter dough—it’s like a hug for your taste buds. The brown sugar caramelizes just enough to balance the richness, and honestly? I’ve never met a cookie that hits this flavor combo quite right.
- Party in a Jar: These freeze like a dream, so I bake a batch on Sundays and pull them out whenever I need a quick treat. Pack them in a jar for school lunches, stash some in the freezer for last-minute guests, or just keep a stash on the counter because… well, they disappear fast.
- Budget-Friendly Indulgence: Peanut butter and sugar are pantry staples, and Reese’s pieces stretch further than fancy chocolate chunks. A single batch makes 24 cookies, and I’ve never once regretted the cost—especially when my kids (or my husband) "accidentally" eat the leftovers before I can. Worth every penny.
Step-by-step instructions for peanut butter cookies with Reese's pieces
Here's how to make these decadent cookies with a perfect fudgy texture and gooey Reese's surprises.
👨🍳 Step 1: Cream Butter, Peanut Butter, and Sugars
In a large mixing bowl, combine the 0.75 cup unsalted butter (cold and cubed), 1 cup creamy peanut butter, 0.75 cup granulated sugar, and 0.75 cup packed brown sugar. Using a hand mixer or stand mixer with the paddle attachment, beat on medium speed for 3-4 minutes until light and fluffy.
You'll know it's ready when the mixture nearly doubles in volume and leaves faint streaks on the bowl. This creaming process incorporates air, which creates that signature tender crumb. If your peanut butter is too thick, microwave it for 10-15 seconds first to make mixing easier.
👨🍳 Step 2: Add Eggs and Vanilla
Add the 2 whole large eggs one at a time, mixing well after each addition. Then add the 1.5 teaspoons vanilla extract and mix for another 30 seconds until fully combined. The mixture should be smooth and slightly thickened.
Here's the thing—don't overmix after adding the eggs or the cookies will be tough. You're just looking to incorporate everything completely. If the mixture looks curdled, don't worry—it will come together when you add the dry ingredients.
👨🍳 Step 3: Fold in Dry Ingredients and Chocolate
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 0.5 teaspoon baking soda, and 0.5 teaspoon salt. Gradually add this mixture to the wet ingredients, mixing on low speed just until combined. Avoid overmixing—you should still see a few flour streaks.
Remove the bowl from the mixer and gently fold in the 1.5 cups Reese's Pieces and 0.5 cup semisweet chocolate chunks using a silicone spatula. Make sure they're evenly distributed throughout the dough. The chocolate chunks will melt slightly during baking, creating pockets of gooey goodness.
⏰ Step 4: Chill the Dough (This Makes All the Difference)
Cover the bowl with plastic wrap and refrigerate for at least 1 hour (I prefer 2 hours or even overnight). Chilling is crucial—it prevents the cookies from spreading too much in the oven and helps develop those rich peanut butter flavors.
Cold dough also means the cookies hold their shape better and develop that perfect fudgy center. If you're short on time, place the dough in the freezer for 30 minutes, but refrigerating gives the best results. Don't skip this step—I learned the hard way that warm dough leads to flat, cakey cookies.
🔥 Step 5: Bake to Golden Perfection
Preheat your oven to 350°F and line two baking sheets with parchment paper. Using a cookie scoop or tablespoon, drop the chilled dough onto the prepared sheets, spacing them 2 inches apart. They won't spread much, but you want room for them to grow.
Bake for 12-14 minutes until the edges are golden brown but the centers still look slightly underdone. The tops should be crackly, and you should see some caramelization around the edges. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Real talk: these cookies are best served warm. The Reese's Pieces and chocolate chunks stay gooey when fresh from the oven, and that's when they're at their best. Enjoy them with a glass of cold milk for the ultimate peanut butter cookie experience!
Pro Tips For Making Peanut Butter Cookie With Reese'S Pieces
- Chill the Dough: After mixing everything, pop the dough in the fridge for at least 30 minutes—yes, even if you’re eager to bake. I used to skip this and ended up with cookies that spread like pancakes and stayed doughy in the center. Cold dough holds its shape and develops better flavor.
- Pack the Brown Sugar: Use a kitchen scale or the "rice method" (scoop brown sugar into a measuring cup, level it, then press it down firmly with a spoon). Packed brown sugar is non-negotiable here—it keeps the cookies chewy and prevents them from tasting dry. Trust me, your taste buds will notice the difference.
- Underbake Slightly: Pull the cookies out when the edges are just set but the centers still look soft—about 10-12 minutes total, depending on your oven. Reese’s pieces melt fast, and overbaking turns them into sad, crumbly messes. Let them cool on the sheet for 5 minutes before moving them.
- Swirl the Peanut Butter: Instead of folding in Reese’s pieces at the end, mix them into the dough in two batches: half after the initial mix, half right before scooping. This ensures every bite has that gooey peanut butter-chocolate contrast without clumping. (And yes, you can skip the extra step of rolling dough balls in chopped pieces—this works just as well.)
Regional styles of peanut butter cookie with reese's pieces
Southern Style
In the South, peanut butter cookies often get a buttery, cake-like texture with a touch of cinnamon. For this regional twist, add 1 teaspoon ground cinnamon to the dry ingredients and replace ¼ cup of the granulated sugar with corn syrup for extra moisture.
Southern bakers also love topping these with a drizzle of peanut butter glaze (mix ½ cup powdered sugar with 1 tbsp peanut butter and 1 tsp milk). I first tried this version at a Georgia bakery where they called them "Peanut Butter Hugs." 🌶️
Pacific Northwest Twist
Here in Portland, we love adding local ingredients with a modern touch. Swap the Reese's Pieces for local dark chocolate chunks (like Pacific Chocolate from Portland) and fold in ¼ cup crushed hazelnuts for texture.
A sprinkle of flaky sea salt (I use Maldon) before baking adds a sophisticated contrast. The hazelnut gives it a nutty depth that pairs perfectly with the peanut butter. Pickles would approve of this version—she’s a big fan of nuts. 🌿
Midwest Classic
Back in Cincinnati, where I grew up, peanut butter cookies were all about simplicity and nostalgia. The classic version here skips extra mix-ins and focuses on the peanut butter flavor. Use 100% natural peanut butter (no sugar added) and add ½ teaspoon cinnamon to the dough.
Bake them slightly longer (14-16 minutes) for a thicker, chewier texture. My neighbor Mrs. Henderson always served these with a tall glass of milk—pure comfort food. 🥛
Gluten-Free Adaptation
For those avoiding gluten, swap the all-purpose flour with a 1:1 gluten-free baking flour (like Bob’s Red Mill 1-to-1) and add ½ teaspoon xanthan gum. Reduce the baking soda to ¼ teaspoon since gluten-free flours often need less leavening.
Chill the dough for 2 hours to help it hold together better. These still turn out tender, just with a slightly denser texture. I’ve tested this version at Portland’s New Seasons Market baking classes, and it’s a hit! 🌱
Vegan Version
To make these vegan, replace the butter with ½ cup vegan butter (like Miyoko’s) or coconut oil, and use flax eggs (mix 2 tbsp ground flaxseed with 6 tbsp water). Swap the honey for maple syrup in the peanut butter glaze.
The dough will be slightly softer, so bake for 10-12 minutes. This version is just as rich and satisfying—my daughter Lily loves these for school bake sales. 💚

Frequently asked questions
Why do your peanut butter cookies need to chill?
Chilling the dough for at least 1 hour (or up to 48 hours) prevents excessive spreading and helps develop deeper peanut butter flavor. Cold dough also ensures those Reese's pieces stay intact during baking, giving you perfect pockets of gooey chocolate in every bite. Skipping this step often results in flat, cakey cookies that lose their signature texture.
Can I substitute regular Reese's cups for the miniature pieces?
Regular Reese's cups are too large and won't melt evenly during baking. The miniature pieces are specifically chosen because they create those perfect surprise pockets of melty chocolate. For a similar effect, chop regular cups into ½-inch pieces before adding them to the dough.
How do I prevent my cookies from cracking?
Cracking usually happens when the dough is too warm or when baking at too high a temperature. Make sure your butter and peanut butter are at room temperature (not melted) and chill the dough thoroughly. Bake at 350°F for 12-14 minutes—any hotter and the tops will crack. Also, avoid opening the oven door during baking.
Can I make these cookies ahead of time?
The dough keeps well in the fridge for 48 hours and can be frozen for 3 months. Baked cookies stay fresh for 5 days in an airtight container, though they're best enjoyed fresh from the oven. For extra flavor, let the dough rest overnight in the fridge before baking.
What's the best way to reheat these cookies?
For warm, gooey cookies, place them on a baking sheet and heat at 300°F for 3-5 minutes. Microwaving can make them rubbery. The reheated cookies will have slightly softer chocolate centers—perfect for a cozy snack. Pro tip: Pair with a glass of cold milk for the full experience.
