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.

These look delicious… I love the PB cookie with Reese’s Pieces. : )
Hi,
Just want to say the cookies look gorgeous! Great idea too :)
But whenever I bake cookies they always get a burnt almost black underside – always. What am I doing wrong??
Love your site by the way :)
I love peanut butter and chocolate. It’s my favorite flavor combination at Baskin Robbins. Congratulations on making the foodbuzz Top 9!
Wow! These look spectacular! Congratulations on top 9 today! :)
Thank you so much for sharing this recipe. They were so delicious, although I also had a problem with the dough being dry, so I just added a little water and that did the trick. These are wonderful!! I need to give them away because they are so good that if I don’t share them I will eat them all :)
That’s so funny about the game! Totally something I would do.
The cookies look amazing. There’s something so irresistible about massive cookies!
My kids would love to eat those home made cookies. It looks so good!
These cookies look amazing and clearly great minds think alike because my upcoming Friday post has Reese’s Pieces as the star ingredient.
Ooh, I love it! I can’t wait to see your recipe!
look at the SIZE of those COOKIES!! bigger is better when it comes to cookies!
These looks awesome!!! Yummy!!!
Was so excited to make these cookies, but I’m reinforcing Adrienne…My dough was very dry, I suspected it would be when I saw 3 3/4 cups flour and only 1/2 cup peanut butter and 1/2 cup butter. Was it supposed to be 2 3/4 cup flour? I may use your idea of the the 3 kinds of chips in my old PB cookie recipe as that’s a great combo! Thanks for the idea of combining those chips.
Hi Lisa, I’m sorry you had some issues with the dough being dry. I left a lengthy response to Adriene above as to what the problem might be. The flour was not a misprint, and my dough was nice and soft. Be sure that the butter has really been softened to room temperature, and it isn’t the least bit cool, and ensure that you give it time to whip together with the peanut butter and sugars. Finally, if it’s still a little dry, you can mix in a tablespoon or two of milk to help it come together.
I had this exact same problemw ith the dough being dry! Such a disappointment as these looked soooo good:) Can’t lie though, the dough still tasted pretty yummy, I just wasn’t able to serve them like I had hoped!
These look like absolute heaven. Holy moly.
Loved this recipe! When I made them, the dough was kind of dry and crumbly. This made making the balls and flattening them much more difficult. Where did I go wrong? They still taste delish, but they just aren’t pretty like yours! Love your blog!
Hi Adrienne, So sorry to hear yours was a little dry. A couple of things that might have caused this. I’ve found that the temperature of butter can have drastic effects on simple cookie recipes. If the butter wasn’t softened enough, then it would crumbled into the sugars and peanut butter, and not softened into a fluffy mixture. Also, be sure to really beat the butter, peanut butter and sugars longer than you think you might need to. They’ll come together in about a minute, but it takes them an additional 1 to 2 minutes to really incorporate, break down, and become light and fluffy. Finally, if you find that your dough is still too dry, you can add a tablespoon or two of milk.
Love everything about these cookies!
Great looking cookies! I wish I had extra candy laying around, mine never seems to last that long!
Thanks for the special delivery cookies today, Michelle. I did share with Uncle Bubbles and they were awesome, even better than I thought! Love you!
You’re welcome, my pleasure! So glad you and Uncle Ray enjoyed the cookies! :) Love you!
I LOVE that you stocked up on baking ingredients at the rink, that’s so awesome. (We don’t discuss not having teams to root for, I’m still trying to decide if I can bring myself to cheer for someone these last few weeks….) These cookies sound insanely good, I’m a huge chocolate/peanut butter fanatic too :)
I know, such a massive bummer. I really don’t care at all who wins at this point, my main objectives were having the Flyers and the Caps eliminated. Now that that’s taken care of (yay!) I have no rooting interest. I guess I’d like to see Phoenix win. If they don’t, then the Devils, since I still like Petr Sykora from when he was with the Pens. It’s hard for me to root for big market teams like NY and LA.
I had the same very dry dough problem and I have tried three separate times, I even left butter on counter overnight so it was room temp. I have a stand mixers it was light and fluffy before added flour mixture but I still had to add almost half cup milk.
I saw these on Pinterest today and had to check it out. So glad I did; they look amazing!
Holy monkey! I’m in love!
i love reeses… and cookies, especially big cookies.
so these are perrrfect
Perfectly shaped cookies!
I am in love! I love peanut butter cookies, and this is just insanely huge and amazing looking!
I think these are the perfect treat to take to the hospital with me this weekend – going to try and butter up the nurses in time for delivery ;) Thanks for sharing the recipe!
Way to be resourceful with the concession card!!! Don’t you love when a pantry full of ingredients becomes a culinary masterpiece??? Another example of your resourcefulness.
“Colossal” is the key word here. YUM!
I love that you were thinking about baking while you were at the game … great food story :-)
These look to die for! Bathing suit weather what? Still far enough away. I need to make these cookies asap!
No chocolate chips for me (allergic :( ). But I have a feeling these cookies will be seriously amazing even without them!
I thought about it and I realized I don’t really need any other type of food for at least a week! :)
What a perfect recipe. I have a friend going through a rough time, this should certainly bring s smile to her. Thanks so much for sharing your recipes!
