A large round cookie sits on a light wooden cutting board with a smooth texture. The cookie is golden brown with a slightly darker edge and is dotted with colorful candy pieces in orange, yellow, and brown, as well as dark chocolate chips. Some candy pieces and chocolate chips are scattered around the cutting board. To the right of the cookie, there is a silver knife resting on the board. In the background, an orange box with bright text is partially open, with more candy pieces spilled out. The surface under the board is a smooth black table. photo taken with an iphone --ar 4:5 --v 7

The ingredients for this cookie are straightforward but essential—they each bring their own magic to the final result. From the creamy peanut butter that forms the base to the Reese’s Pieces that add bursts of color and texture, every element plays a critical role in making this cookie truly unforgettable.

Peanut butter: Choose a creamy style for the best chewy texture and nutty flavor in the cookie.
Sugar: A mix of brown and granulated sugar adds sweetness and helps create a nice chewy crust.
Egg: Acts as the binder, giving the dough structure and richness.
Vanilla extract: Adds warm, fragrant notes that complement the peanut butter perfectly.
Baking soda: Helps the cookie spread just right and rise lightly for softness.
Salt: Enhances the flavors and balances the sweetness beautifully.
Reese’s Pieces: These colorful candies provide the cookie with bursts of chocolatey crunch and vibrant visual appeal.

Directions

Step 1: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This helps ensure your giant cookie bakes evenly and doesn’t stick.

Step 2: In a medium bowl, combine 1 cup of creamy peanut butter with ¾ cup of brown sugar and ½ cup of granulated sugar. Use a hand mixer or wooden spoon to mix until smooth and creamy. This will be your cookie dough base.

Step 3: Add in 1 large egg and 1 teaspoon of vanilla extract to the peanut butter mixture and beat until fully blended. The dough should be smooth and cohesive.

Step 4: Stir in ½ teaspoon of baking soda and a pinch of salt, mixing until just combined. These will help the cookie rise slightly and balance the flavors perfectly.

Step 5: Gently fold in about ½ cup of Reese’s Pieces, saving a few to sprinkle on top later for extra color and flair.

Step 6: Shape the dough into one large cookie on your prepared baking sheet. I usually spread it out to about 6-7 inches in diameter, roughly 1-inch thick. Then press the remaining Reese’s Pieces on top for a pretty, inviting look.

Step 7: Bake in your preheated oven for 15-18 minutes. You want the edges to be set and just golden, while the center still looks slightly soft—this is key to that delightful chewy texture.

Step 8: Remove from oven and let it cool on the baking sheet for about 10 minutes before transferring to a wire rack to cool completely. This resting time helps the cookie firm up without losing softness.

Servings and Timing

This recipe makes one giant cookie that’s perfect for serving 2 to 4 people depending on appetite. Prep time is incredibly quick around 10 minutes, and baking takes about 15 to 18 minutes. Including cooling, the total time you’ll need is roughly 30 to 35 minutes. It’s a fast and rewarding bake that’s perfect for those moments you want an impressive homemade dessert without all the fuss.

How to Serve This Giant Reese’s Pieces Peanut Butter Cookie Recipe

A single large cookie rests on a beige baking mat with a thin orange border, placed on a white marbled surface. The cookie is golden-brown and studded with orange, yellow, and dark brown candy pieces and chocolate chips spread evenly across its slightly cracked surface. Behind the cookie, there is an open orange box of Reese's Pieces candy with colorful candy images on it, and a red oven mitt with white polka dots is partially visible in the background.

I love serving this cookie slightly warm so you can really appreciate that soft, chewy center and melty pockets of peanut butter and chocolate. It’s perfect plated with a scoop of vanilla ice cream or a drizzle of hot fudge for an indulgent treat that feels like a celebration. If you want to keep it simple, just placing it on a dessert plate with a glass of cold milk is a nostalgic crowd-pleaser.

For festive occasions like birthdays, family gatherings, or holiday parties, this cookie makes a fantastic centerpiece. You can garnish it with a sprinkle of flaky sea salt or extra Reese’s Pieces right before serving to add visual interest and an extra layer of flavor. I also find it pairs wonderfully with coffee or a creamy milkshake for a fun twist on dessert and snacks.

When it comes to portioning, I like to slice this giant cookie into wedges, almost like a cookie pie. It’s such a great way to share and everyone gets to enjoy those colorful candy spots. It also travels well if you’re taking it to a party or potluck—just slice and arrange on a pretty platter for instant smiles.

Variations

If you want to switch things up, I’ve had great results swapping in chunky peanut butter instead of creamy for added texture. You can also play with the candy mix-in—M&Ms, Mini Reese’s Cups chopped up, or even chocolate chips give the cookie a whole new vibe. Just keep the candy-to-dough ratio balanced to avoid the cookie becoming too heavy.

For those looking to adapt for dietary needs, you can try a gluten-free flour blend in place of regular flour if you want to add some for structure, although this particular recipe is naturally gluten light with no flour added. Vegan versions are achievable by substituting the egg with a flax or chia “egg” and using a dairy-free peanut butter and vegan candies, though expect some differences in texture. I always encourage experimentation because that’s part of the fun!

Different cooking methods like using a skillet on the stovetop to cook a giant cookie “pancake” style can be fun too if you want a crispy edge and gooey middle. Just watch your heat carefully to avoid burning and adjust cook times accordingly.

Storage and Reheating

Storing Leftovers

If you have any cookie left (which might be rare), store it in an airtight container at room temperature for up to 3 days. I recommend placing a piece of parchment paper between any slices to keep them from sticking together. This maintains the cookie’s chewy texture and delicious freshness.

Freezing

You can absolutely freeze this cookie! Wrap it tightly in plastic wrap and then place it in a freezer-safe bag or container. It will keep well for up to 2 months. When you want to enjoy it again, just thaw it at room temperature before warming it slightly for the best taste experience.

Reheating

To bring back the cookie’s soft, melty magic after storage or freezing, pop slices in the microwave for about 10-15 seconds or warm in a low oven at 300°F (150°C) for 5 minutes. Avoid overheating as it can dry out the cookie. Reheating enhances the peanut butter flavor and refreshes the candy’s crunch.

FAQs

Can I make this cookie smaller or in multiple portions?

Absolutely! You can divide the dough into smaller balls and bake them as individual cookies. Just reduce the baking time to about 10-12 minutes and watch for golden edges. They will be just as delicious but more portion-friendly for sharing or gifting.

What if I don’t have Reese’s Pieces—can I use something else?

Definitely! You can use M&Ms, chopped peanut butter cups, chocolate chips, or even chopped nuts. Each option will bring its own flair, so feel free to experiment based on what you have or your flavor preferences.

Is it important to cool the cookie before eating?

While you can enjoy this cookie warm, I recommend letting it cool for at least 10 minutes. This resting time helps it set so it doesn’t crumble when you cut into it and gives you the perfect chewy texture that makes this recipe special.

Can I make this recipe dairy-free or vegan?

Yes! Use dairy-free peanut butter, vegan-friendly candies, and replace the egg with a flax or chia egg for a vegan version. The texture may vary slightly, but it’ll still be delicious and peanut buttery.

How do I prevent the cookie from spreading too much?

Make sure not to add extra oil or butter since peanut butter alone provides fat. Also, chilling the dough for 20-30 minutes before baking can help the cookie hold its shape better if you want a thicker, more structured cookie.
