This peanut butter cookie with Reese's pieces recipe delivers the perfect balance of rich peanut butter flavor and sweet, crunchy Reese’s bursts in every bite.

Store them in an airtight container for up to a week, though they rarely last that long in my house.
For extra indulgence, drizzle melted chocolate over the cooled cookies or press additional Reese’s pieces into the tops. These are perfect for holiday gifts, potlucks, or satisfying that 3 PM sweet tooth. Let’s get baking—your taste buds will thank you.
Ingredients for peanut butter cookie with reese's pieces
Just 12 ingredients for cookies that taste like childhood nostalgia.
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 cup | Natural, unsweetened preferred |
| Brown Sugar 🍚 | 1 cup | Packed firmly for accuracy |
| Granulated Sugar 🍚 | ½ cup | For balanced sweetness |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Unsalted Butter 🧈 | ½ cup | Cubed and softened |
| Vanilla Extract 🌿 | 1 tbsp | Pure, not imitation |
| All-Purpose Flour 🌾 | 1 ½ cups | Spooning and leveling for precision |
| Baking Soda 🧂 | ½ tsp | For lift and tenderness |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Reese's Pieces 🍫 | 1 ½ cups | Original flavor, not miniatures |
| Semisweet Chocolate Chips 🍫 | 1 cup | High-quality for extra flavor |
| Milk 🥛 | 2 tbsp | Any variety works fine |
The peanut butter makes or breaks these cookies. Natural, unsweetened is ideal—it’s richer and less processed than the sweetened kind. If you’re using a jarred brand, Jif or Skippy are reliable, but store brands work too. Pro tip: scoop the peanut butter straight from the jar with a spoon—no need to measure it separately. The brown sugar should be packed firmly, not just dumped loosely. For the Reese’s pieces, stick to the classic white candy coating—the miniatures melt differently and can make the dough too soft. Buy extra if you’re sharing; they disappear fast.
No creamy peanut butter? Crunchy works in a pinch, but the texture will be slightly different. Running short on Reese’s? M&M’s or white chocolate chips add a similar crunch, though the flavor won’t be identical. The chocolate chips are non-negotiable for binding the dough—skip them and the cookies won’t hold together as well. If you’re worried about the dough being too sticky, add 1 extra tablespoon of flour. And trust me on the milk: it’s worth the extra step to dissolve the peanut butter properly before mixing.
The dough keeps for 3 days in the fridge, wrapped tightly in plastic. For longer storage, freeze portions for up to 3 months. Once baked, let the cookies cool completely before storing in an airtight container—they’ll stay fresh for 5-7 days. Pro move: bake half the dough, then freeze the remaining dough balls on a tray before transferring to a bag. That way, you can bake fresh cookies whenever the craving hits without dealing with melted dough.

Step-by-step instructions for peanut butter cookies with Reese's pieces
Here's how to make cookies with that perfect peanut butter flavor and gooey Reese's surprises in every bite.
Cream Peanut Butter and Sugars Together
In a large mixing bowl, combine the 1 cup creamy peanut butter, 1 cup packed brown sugar, and 0.5 cup granulated sugar. Using a hand mixer or stand mixer with the paddle attachment, beat on medium speed for 3-4 minutes until the mixture is smooth and light in color. You'll notice it nearly doubles in volume and becomes fluffy—this is what creates that classic peanut butter cookie texture.
I like to scrape down the sides of the bowl with a rubber spatula every 30 seconds to ensure everything gets evenly incorporated. This step is crucial because it fully blends the peanut butter's rich flavor with the sugars, creating the perfect base for your cookies. If your peanut butter is particularly thick, you might need to mix for an extra minute to achieve that silky consistency.
Add Eggs, Butter, and Vanilla
Add the 2 whole large eggs, 0.5 cup softened unsalted butter, 1 tablespoon vanilla extract, and 2 tablespoons milk to the peanut butter mixture. Beat on medium speed for 2-3 minutes until everything is fully combined and the mixture looks smooth and homogenous. The butter should be fully incorporated, leaving no visible lumps.
This is where the magic happens—the eggs bind everything together while the butter adds richness. I always use room-temperature eggs for even mixing, and I've found that adding the milk at this stage helps create a smoother dough. If the mixture seems too thick, add just 1 more tablespoon of milk to help it come together properly.
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 dry mixture to the peanut butter mixture, mixing on low speed just until combined. Be careful not to overmix—you should still see some flour streaks when you're done.
Remove the bowl from the mixer and gently fold in the 1.5 cups Reese's Pieces and 1 cup semisweet chocolate chips using a silicone spatula. I like to distribute them evenly throughout the dough so every bite has those delicious surprises. If you're worried about the chocolate melting, don't be—the dough will hold its shape until it hits the oven.
Chill the Dough for Perfect Cookies
Cover the mixing bowl with plastic wrap and refrigerate for at least 30 minutes, or up to 24 hours if you have time. Chilling the dough is essential—it prevents the cookies from spreading too much in the oven and helps the flavors meld together. When you're ready to bake, take the dough out and let it sit at room temperature for 10-15 minutes to make it easier to scoop.
I know it's tempting to skip this step, but trust me—chilled dough makes a world of difference. The cookies will hold their shape better, and you'll get that perfect balance of crispy edges and soft, gooey centers. Plus, the peanut butter flavor will be even more pronounced after chilling.
Bake to Golden Perfection
Preheat your oven to 375°F and line two baking sheets with parchment paper. Using a cookie scoop or tablespoon, drop 1.5-tablespoon portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each portion slightly with your palm—this helps them spread evenly in the oven.
Bake for 9-11 minutes, or until the edges are golden brown and the centers look just slightly underdone. The cookies will continue to set as they cool, so don't overbake them. I like to rotate the baking sheets halfway through for even baking. Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Enjoy your cookies warm for the best texture—they'll be soft and chewy inside with crispy edges, and every bite will have those delicious Reese's Pieces and chocolate chips. Store any leftovers in an airtight container for up to 5 days, or freeze for up to 3 months for freshly baked cookies anytime you want.
Pro Tips For Making Peanut Butter Cookie With Reese'S Pieces
- Chill the Dough: After mixing, 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 flat, greasy cookies that spread like pancakes. Cold dough holds its shape, and the Reese’s pieces stay put instead of sinking to the bottom.
- Use Room-Temp Butter: Take the butter out of the fridge 1-2 hours before mixing—it should be soft but not greasy. Cold butter creates pockets of air that make cookies spread unevenly, while overly soft butter makes them dense. My grandmother swore by this, and she was right: the texture is night and day.
- Don’t Overmix: Stop mixing the dough as soon as the peanut butter and sugars come together—usually 30-45 seconds. Overworking it heats up the butter and turns the dough tough. I learned this the hard way when my cookies turned out chewy and dry instead of soft and fudgy.
- Bake in Two Batches: Crowding the pan leads to uneven baking and flat cookies. Use half the dough per sheet, and space them 2 inches apart. Sounds tedious, but it guarantees thick, gooey centers and crisp edges—no one wants a sad, pancake-like peanut butter cookie. (Your future self will thank you.)
Health benefits of these flavors
Protein Powerhouse
These cookies pack a surprising 4 grams of protein per serving (about 2 cookies) thanks to the peanut butter base. That’s more than many store-bought cookies and helps keep you full longer.
The protein comes from peanuts themselves, which also contain healthy fats that support brain function and energy levels. 💪
Energy Boosting Carbs
The brown sugar and peanut butter provide complex carbohydrates that fuel your body with sustained energy. Unlike refined white sugar, brown sugar contains trace minerals like calcium and iron.
These cookies are perfect for a post-workout snack when paired with a glass of milk, creating a classic protein-carb combo for muscle recovery.
Chocolate Antioxidants
The Reese’s Pieces and chocolate chips add flavonoids, powerful antioxidants that protect your cells from damage. Darker chocolate contains more antioxidants, but even milk chocolate provides benefits. These antioxidants may help improve heart health by reducing inflammation and supporting blood vessel function. 💛
Happy Mood Enhancers
Peanut butter contains tryptophan, an amino acid that converts to serotonin—your body’s natural "feel-good" chemical. The combination of peanut butter, chocolate, and sugar creates a triple threat for instant mood elevation.
That’s why these cookies are my go-to when I need a quick pick-me-up after a long day of gardening with Pickles the cat.
Portion Control
While delicious, these cookies are calorie-dense at about 180 calories per serving. The good news is that the protein and fiber help balance blood sugar spikes.
I recommend enjoying them as a treat rather than a daily staple, and always store them in an airtight container to maintain freshness and portion control. The Reese’s pieces make them irresistible, but moderation is key!
Nutrition facts
Frequently asked questions
Why do your cookies need to chill before baking?
Chilling the dough for at least 30 minutes prevents excessive spreading and helps the peanut butter flavor develop fully. The cold dough also creates those perfect crisp edges while keeping the centers soft. Think of it like giving your cookies time to set their intentions before baking!
Can I substitute Reese's Pieces with something else?
Try M&M's or white chocolate chips for a similar crunch. For extra indulgence, fold in chopped peanuts or toasted coconut flakes. Just remember the Reese's pieces give that signature peanut butter-chocolate combo that makes these cookies special.
How do I tell when the cookies are done baking?
Look for golden brown edges and a slightly underbaked center - the cookies will firm up as they cool. They should pull away from the parchment paper but still look soft in the middle. Overbaking makes them dry, so err on the side of 9-10 minutes rather than pushing to 11 minutes.
Can I make these cookies gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free flour blend (like Bob's Red Mill) and add 1/4 teaspoon xanthan gum to help bind the dough. You may need to chill the dough longer (up to 1 hour) as gluten-free dough spreads more. The texture will be slightly different but still delicious.
What's the best way to store leftover cookies?
Keep them fresh in an airtight container at room temperature for up to 5 days. For longer storage, freeze the baked cookies (up to 3 months) or freeze dough balls (up to 3 months) on a tray before transferring to a bag. Reheat in the oven for 5-10 seconds to restore crispness.
