Ingredients - Here's What You'll Need

Steps to Make Thick and Chewy Peanut Butter Chocolate Chip Cookies
- Beat room temperature butter with an electric hand mixer in a large bowl. Then add dark brown and white sugars and beat for about 3 minutes, or until light and fluffy.

- Then, beat in two large eggs, one egg yolk, and vanilla extract.

- Next, beat in crunchy peanut butter.

- Then, add about half of the flour and the baking soda, and beat until just combined. Add remaining flour, beating until just combined.

- Add 6 ounces mini semisweet chocolate chips and one package of Reese's Peanut Butter Cups Minis Unwrapped.

- Stir them into the dough to combine.

- Line a half sheet pan with parchment paper. I used my half sheet pan with a lid. Then, use a 2-oz ice cream scoop to portion the dough into 24 balls.

- Roll the dough balls between gloved hands and flatten slightly.

- Place three Reese's Peanut Butter Cups Minis Unwrapped and about 10 mini semisweet chocolate chips on top of each dough ball. Cover the pan and refrigerate for at least 12 hours, or overnight. If you don't have a half sheet pan with a lid, place a piece of parchment on top of the dough and cover the entire pan with plastic wrap.

- When you're ready to bake the cookies, preheat your oven to 350°F. Line three half-sheet pans with parchment paper. Place eight refrigerated dough disks, about two inches apart, onto one of the prepared pans. Then, bake for 15-18 minutes. Repeat with the other two pans and the rest of the dough, baking the pans one at a time and leaving the unused dough in the refrigerator between bakes.

- Remove the pan from the oven and allow the cookies to cool for 15 minutes on the pan.

- Transfer the cookies to a wire cooling rack to cool completely. Store in an airtight container for up to a week.

Frequently Asked Questions
Chilling the dough is an essential step for this recipe! It solidifies the fats in the cookie dough, which prevents the cookies from spreading too rapidly and flattening out in the oven. This ensures your cookies bake up beautifully thick, robust, and satisfyingly chewy. If you bake the dough while it is warm, the cookies will spread thin, lose their signature density, and become crispy rather than thick and chewy. If you are short on time, you can speed up the process slightly by placing the dough in the freezer for about an hour.
Using salted European-style butter is the ultimate secret to achieving a thick, dense texture and a rich flavor profile. Because European butter has a higher butterfat content and less water than standard American butter, it creates less steam in the oven, preventing the cookies from spreading flat and ensuring a heavy, substantial chew. Additionally, the cultured richness and built-in salt perfectly amplify the savory notes of the peanut butter, cutting through the sweetness for a flawless sweet-and-salty balance.
Using crunchy peanut butter elevates the texture of these cookies without altering the base recipe. While creamy peanut butter completely melts into the dough, crunchy peanut butter contains real fragments of chopped peanuts that hold their integrity during the baking process. This injects a distinct, rustic contrast against the dense, soft dough, giving every single bite a satisfying crunch. Additionally, those pockets of real peanuts deliver bursts of intact, roasted, salty flavor, which help break up the cookie's heavy sweetness and bring out a more authentic, deep peanut aroma.
Absolutely! This dough freezes beautifully. Scoop and prepare the dough for refrigeration, and place the balls on a baking sheet to freeze solid. Once frozen, transfer the balls to a zippered freezer bag for up to 3 months. When you are ready to bake, you can bake them straight from the freezer-just add an extra minute or two to the total baking time.

Recipe Tips and Tricks
- Do Not Over-Bake for the Perfect Chew: Pull the cookies out of the oven when the edges are just set and golden brown, even if the centers still look a little soft. They will continue to firm up into a perfectly dense, substantial bite as they cool on the baking sheet.
- The White Bread Storing Trick: To keep your baked cookies soft and chewy for up to 5 days, store them in an airtight container with a single slice of plain white bread. The cookies will absorb the moisture from the bread, keeping them from drying out or getting crumbly.
- Keep the Mix-Ins Small: Using mini chocolate chips and small peanut butter cup pieces ensures that every single bite gets an even distribution of chocolate and peanut butter flavor, without heavy, oversized chunks breaking up the cookie's structure.
- Try the "Cookie Scoot" Trick: For perfectly round, picture-perfect cookies, grab a round cookie cutter (or a wide glass/mug) slightly larger than the cookie immediately after taking the baking sheet out of the oven. Place it over the hot, pliable cookie and gently swirl it in a circular motion. This pulls in any stray edges, making the cookie perfectly circular, thick, and uniform.
