Colossal Reese’s Pieces Chocolate Chip Cookies

My infatuation with the combination of chocolate and peanut butter is very well-documented here on the site. You put the two of them together and I’m completely unable to practice any sort of restraint. The good news? I know I’m not alone. I’ve been thrilled to hear from all of the other chocolate/peanut butter fanatics out there! So, it probably comes as no surprise that I keep finding new ways to throw the two of them together. Sometimes, the ideas are born out of desperation (I need some chocolate and peanut butter immediately). Sometimes, I see a recipe on a blog, in a magazine or in a cookbook that looks irresistible, and sometimes, I stare at my pantry ingredients and see the perfect storm. These cookies were born out of a perfect storm. In fact, you know that enormous rogue wave that kills George Clooney at the end of the movie by the same name? It has just met its culinary counterpart.

Speaking of infatuations, most of you also know I’m a hockey fanatic and a huge Penguins fan. Last year, when tickets went on sale for the upcoming season, I had my sights set on one game.
Thursday, December 29th.
Flyers vs. Penguins.
The return of Max Talbot and Jaromir Jagr.
My little fingers click, click, clicked away on Ticketmaster at exactly 10:00am the morning tickets went on sale, but they were immediately sold out. I figured I would check StubHub as the game got closer and try to snag tickets. Lo and behold, a couple of months later, I received my regular Penguins email newsletter. Nestled at the bottom of the email was a notice that the team would be selling 3-game packages for all of the home games versus the Flyers. My fingers have never typed so fast. To say that purchasing that ticket package was an impulse purchase would be the understatement of the century. The thing about those tickets, though? They came pre-loaded with $25 worth of concessions. Turns out, it’s pretty hard for two people to eat and drink $50 worth of concessions at one game. We were at the last game of the season, and I realized there was still a balance on our two tickets, even after we had eaten and gotten drinks. Not willing to throw it away, I hit the concession stand one last time. What did I buy? I stocked up on Reese’s Pieces, of course! “I can use these to bake!” was my immediate exclamation.

Fast forward a month, and in my drawer of baking goodies, I see the following:
An unopened bag of Reese’s peanut butter chips.
Boxes of Reese’s Pieces.
Three half-full bags of chocolate chips.
A jar of peanut butter.
The perfect storm. Obviously, these cookies were meant to be. Massive, soft, and chewy. Packed with tons of peanut butter and chocolate. They’re amazingly delicious, and they make the fact that I have no hockey team to root for in May just slightly more bearable.

Colossal Reese's Pieces Chocolate Chip Cookies
Ingredients
- 3¾ cups (468.75 g) all-purpose flour
- 1½ teaspoons (1.5 teaspoons) baking soda
- ¾ teaspoon (0.75 teaspoon) salt
- ½ cup (113.5 g) unsalted butter, at room temperature
- ½ cup (129 g) creamy peanut butter
- 1 cup (220 g) light brown sugar
- ¾ cup (150 g) granulated sugar
- 2 eggs
- 4 teaspoons vanilla extract
- 1½ cups (270 g) semisweet chocolate chips
- 1 cup (170 g) peanut butter chips
- 1 cup (188 g) Reese's Pieces
- Fleur de sel, for sprinkling (optional, but awesome!)
Instructions
- Preheat oven to 350 degrees F. Line two baking sheets with parchment paper; set aside.
- In a medium bowl, whisk together the flour, baking soda, and salt; set aside.
- With an electric mixer on medium speed, cream together the butter, peanut butter, and both sugars until light and fluffy, about 3 minutes. Scrape down the sides of the bowl, add the eggs and vanilla extract, and beat until combined. Reduce the mixer speed to low and gradually add the flour, mixing until it has almost all been incorporated. Add the chocolate chips, peanut butter chips, and Reese's Pieces, and mix briefly (about 20 seconds) to ensure they are evenly distributed.
- Roll a ¼ cup of dough into a ball and place on one of the baking sheets. Repeat with the rest of the dough - you should end up with about 18 cookies. With your fingers, press down on the balls of dough to flatten into disks, about ½-inch thick. Sprinkle with a pinch of Fleur de Sel. Bake the cookies for 12 to 15 minutes, just until the edges of the cookies are beginning to turn a light brown. Cool the cookies on the baking sheets. Store in an airtight container at room temperature for up to 5 days.

Any cookie with the words Reeses and Colossal is my kind of cookie! These look so yummy.
Perfection! This is my type of cookie!

chocolate and pb are the best ever. and I love that you used your credit to have the ingredients! genius :)
Seriously making these this weekend. If I can wait that long!
Yummy, I made cookies like this off of Elle’s New England Kitchen but didn’t have pb chips in there. These look like awesome cookies!
Any cookie that is described as colassal has to be a winner in my book! :)
I hate to show my ignorance, but what is Fleur de sel and where might I find it? Unfortunately, the Pens let us down and it looks like it’s going to be a lonnnng summer until training camp starts.
Hi Heather, Fleur de sel is a flaky sea salt, similar to maldon. I haven’t found it in local grocery stores, but you can buy it at places like Williams-Sonoma, Sur la Table, Amazon, King Arthur Flour, etc.
These look like my perfect cookie! Yum!
I think you need to save one for your aunt……or am I too late?
Absolutely! Not too late at all :) I’ll text you… I’ll be in your area today, I can drop a couple off to you!
These cookies are so calling my name. Chocolate and peanuts butter are definitely made to go together.
This is a cookie. A reallll cookie.
I LOVE Reece’s pieces. They have always been my favorite since I am allergic to chocolate. Adding them to cookies? Out of this world good!
Bookmarked. I’m in love with giant bakery-style cookies!
I saw these pop into my email this morning and my jaw dropped. Well, of course, first I read Peanut Butter Cups and thought wow! Colossal and PB Cups (which would be awesome)! Then I read Reese’s Pieces – equally as cool. I’m going to try and make these for the office!
I love these! Yum!
This is like my dream cookie recipe. Thank you for making dreams come true!
Like you, I am hooked on this combination and will be trying these THIS week!
Thanks…

These look amazing! I also have a love of all things chocolate and peanut butter together. How could that be wrong? I think it’s hilarious that your last buy on your card were for something to bake with later. That’s thinking ahead!
I think nothing is better than chocolate and peanut butter! In college, my roommate and I would live on Hershey bars dipped in peanut butter! Yes, we got the freshman 15! These looks so good. I happen to have Reese’s Pieces at home….
You caught my attention with the word “colossal”! Who doesn’t like their cookies “massive, soft, and chewy”?? These look scrumptious!
Huge and peanutty and chocolatey? Count me in :D
Cheers

Hi Margot, No, you could definitely make them smaller, just be sure to reduce the baking time.
