Let's get started on these irresistible peanut butter cookies with Reese's pieces!

Ingredients for peanut butter cookie with reese's pieces

Peanut butter, chocolate, and butter—these three stars make magic happen in every bite.

The peanut butter is non-negotiable here—natural, no-sugar-added gives the best flavor without overpowering. Jif Natural or Smucker's are my go-tos, but any creamy variety works. For the butter, full-fat is a must—low-fat cuts the richness you're craving. The Reese's pieces? Original flavor only—the chocolate-pb combo is what we're after. Grab the big bag at Costco or Sam's Club if you're making a batch for a crowd. Pro tip: Chill your peanut butter for 10 minutes before measuring—it thickens when cold, so you'll get a more accurate cup.

No Reese's pieces? Chop up a Reese's cup bar—it's the same stuff, just in a different shape. Running low on chocolate chips? Use mini M&M's or butterscotch chips for a fun twist. The vanilla extract can be swapped for vanilla bean paste if you're feeling fancy, but regular extract works perfectly fine. For the sugars, light brown adds moisture, while white keeps things crispier. Mixing them gives you the best of both worlds. If you're gluten-free, substitute the flour for a 1:1 gluten-free blend—just don't skip sifting it first.

This dough needs at least 1 hour of chilling—don't rush it! The longer it rests, the better the flavor develops. Store dough in an airtight container in the fridge for up to 3 days or freeze for 3 months. Baked cookies keep at room temp for 5 days in an airtight container, but they won't last that long. Portion into single-serving bags for gifting—everyone will think you're a baking pro. And if you make extras? Freeze them on a tray first so they don't stick together when you pull them out later.

Step-by-step instructions for peanut butter cookies with Reese's pieces

Here's the foolproof method for chewy, nutty peanut butter cookies packed with chocolatey surprises!

In a large mixing bowl, combine the 1 cup creamy peanut butter and 1 cup softened unsalted butter using a hand mixer or stand mixer. Beat on medium speed for 2-3 minutes until completely smooth and lightened in color. You're looking for a creamy, fluffy texture that nearly doubles in volume.

This step is crucial—it ensures your cookies will have that perfect chewy texture. If you notice any lumps of peanut butter, press them against the side of the bowl with a spatula and let the mixer work them in. The mixture should be completely homogeneous before moving forward.

Add the 0.75 cup granulated sugar and 0.5 cup packed brown sugar to the peanut butter mixture. Beat on medium-high speed for 1-2 minutes until the sugars are fully incorporated and the mixture is thick and creamy. Scrape down the sides of the bowl with a rubber spatula to ensure everything gets mixed in evenly.

Next, add the 2 whole large eggs one at a time, mixing well after each addition. Then stir in the 2 teaspoons vanilla extract until fully combined. The mixture should be thick, smooth, and slightly sticky. This is your base dough—don't worry if it looks a bit too much, it will come together perfectly in the next step.

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 your peanut butter mixture, mixing on low speed just until combined. Avoid overmixing—you want to maintain a slightly thick, sticky dough.

Now for the fun part! Remove the bowl from the mixer and fold in the 1.5 cups Reese's Pieces and 1 cup chocolate chips using a silicone spatula. Make sure they're evenly distributed throughout the dough. This is where the magic happens—each bite will be packed with those iconic peanut butter cups and melty chocolate!

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes (I prefer 1 hour for best results). Chilling the dough is essential—it prevents the cookies from spreading too much in the oven and helps develop that perfect chewy texture. The dough should be firm enough to handle but still slightly sticky when you take it out.

While the dough chills, preheat your oven to 350°F and line two baking sheets with parchment paper. This gives you plenty of time to get everything ready before baking. Pro tip: Place the dough in the fridge while you're prepping your oven to keep it cold.

Using a cookie scoop or tablespoon, drop 1.5-tablespoon portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. They won't spread much, so you can place them a bit closer together than you might with regular chocolate chip cookies.

Bake for 10-12 minutes until the edges are lightly golden brown but the centers still look slightly underdone. The cookies will continue to set as they cool, so don't overbake them. You're aiming for that perfect chewy texture with just a hint of crispness around the edges.

Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This short cooling time helps maintain their chewy texture. I know it's tempting to grab one warm off the tray, but resist the urge—they'll be even better once fully cooled and set.

Once cooled, store any leftovers in an airtight container at room temperature for up to 5 days. These cookies are so good, they rarely last that long in my house! Serve them with a glass of cold milk for the ultimate peanut butter cookie experience.

Wine and beer pairings for peanut butter cookie with reese's pieces

Sweet Milk Pairings

There's nothing quite like the classic combination of warm peanut butter cookies and cold milk. I always reach for whole milk—its richness complements the peanut butter perfectly without overpowering the chocolate. For an extra special treat, try organic whole milk from local dairies in Portland.

If you prefer something lighter, vanilla almond milk adds a subtle floral note that pairs beautifully with the peanut butter's nuttiness. 🥛

Creamy Coffee Lattes

For an afternoon pick-me-up, serve these cookies with a vanilla latte made with 2% milk. The warmth of the coffee cuts through the richness of the peanut butter, creating a perfect balance.

I love using local roasts from Stumptown Coffee—their medium-dark roasts have just the right amount of bitterness to complement the sweetness. Add a dash of cinnamon to your latte for an extra cozy touch that ties into the cookie's flavors.

Chocolate Milk Fusion

Here's a fun twist I discovered when my daughter Lily was little: chocolate milk! Mix 1 cup whole milk with 2 tablespoons Hershey's cocoa powder and a touch of vanilla extract for a drink that mirrors the cookie's chocolatey elements.

The peanut butter cookie's nuttiness shines through while the chocolate milk enhances the overall chocolate experience. This pairing is especially popular with kids (and let's be honest, adults too!).

Light Iced Tea

For a refreshing alternative, try pairing these cookies with sweet iced tea. Brew a strong batch of black tea (I prefer Earl Grey for its bergamot notes) and sweeten it with honey or simple syrup.
