These Cookies With Reese’s Peanut Butter Cups Are Perfect For Halloween
Happy Halloween! I figured I’d celebrate with a candy filled cookie today, so I’m sharing these delicious Reese’s Peanut Butter Chocolate Cookie Cups! Yay for candy and costumes!
I don’t really remember too many of the costumes I wore as a kid. I think I was a witch a few times. Probably my favorite costume (that I can remember at least – how old am I? what happened to my memory?) was in college when I dressed up as Michael Jackson. I love him. Best performer of all time.

I assume most college towns are this way, but in Chapel Hill (go heels!) the main street going through campus was always JAM PACKED on Halloween. Everyone was dressed up and milling around checking out the costumes. There were usually some pretty funny and original ones.
I’ve always been a big Michael Jackson fan. I remember being in third grade at after school with my boom box and barbie dolls jamming out to his Dangerous cd. It truly is one of life’s big bummers that I’ll never get to see him in concert.

But I do think I made a pretty good version of him for Halloween. Walking around campus that year everyone knew who I was supposed to be, which to me meant I had totally succeeded.
There are so many looks I could’ve gone with, but I went with his look from one of my very favorite performances – his 1995 VMA performance, when he performs one of my favorites, ‘Dangerous’ (about halfway through the performance). It seemed doable. So many of his costumes are over-the-top and awesome, but hard to replicate. I added the sparkly glove because duh. You can’t be Michael Jackson without the glove.

I used to do a lot of sewing, so I actually made the glove myself. I still have the glove and hat. They’ve been used a number of times as kind of a last resort costume when we need one. The hub’s loves him too, so he’s used it a number of times, this year included.
That year was the only year I really ever remember putting much effort into a costume, so I’m quite proud of it.
This year, since we don’t have kids yet, we won’t be going around trick or treating, but we will be passing out candy. I’ve always thought the best part of Halloween was the candy, so I love getting a wide variety and letting kids pick their favorite.

What Is The Best Way To Decorate These Reese’s Cookies?
Reese’s are definitely a favorite around here, so I figured why not stuff that delicious little sucker into a cookie? You can dress it up if you want with some icing and maybe some chocolate sauce on top, or you can leave it naked. Your call. I personally love icing and will put it on just about anything. 🙂

Ingredients
Chocolate Cookie Cups
- 3/4 cup salted butter (room temperature)
- 1 cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 cup natural unsweetened cocoa powder
- 1 tsp baking soda
- 2 tsp cornstarch
- 36-40 mini Reese's
Peanut Butter Buttercream
- 1/4 cup butter (room temperature)
- 1/4 cup shortening
- 1/4 cup creamy peanut butter
- 2 cups powdered sugar
- 2-3 tbsp milk ( or water, as needed)
Instructions
- Preheat oven to 350℉.
- Add the butter and sugar to a large mixing bowl and cream together on medium speed until light in color and fluffy in texture, about 3-4 minutes.
- Add egg and vanilla extract and mix until well combined.
- Add dry ingredients and mix thoroughly. Dough will be thick.
- Grease a mini muffin tin.
- Make balls of about 2 large tsp in size and press into the bottom of each mini muffin cup. Press the center down just a bit to make an indention, where you'll add the Reese's later. You want each cup to only be about 3/4 full.
- Bake at 350℉ for 8 minutes. While cookies are baking, unwrap the mini Reese's.
- Remove cookies from oven (the centers may look a little undone, but they will cook more as they sit) and press a Reese's into the center of each of the cookie cups.
- Allow to cool for 3-4 minutes in the muffin tin.
- Remove cookies to a cooling rack to finish cooling.
- To make the buttercream, beat the shortening and butter together in a large mixer bowl until smooth.
- Add the peanut butter and mix until well combined and smooth.
- Slowly add the powdered sugar and mix until well combined and smooth. Add milk or water, as needed, to thin out the frosting and mix until well combined and smooth.
- Pipe buttercream onto cooled cookie cups.

I made these cookies with the white chocolate peanut butter cups, and then put sprinkles on the tops before the chocolate set. I did not use the buttercream. They’re delicious and I love the way they look!
Awesome! So glad you enjoyed them!
Can you use a liner for this recipe. I tried without the liner and had problems with them sticking to the pan
Sure, I would think that’d be fine.
These were delicious. The peanut butter icing really makes this cookie…..it was a hit at the Christmas party…
I’ve tried making these twice and both times the Reese’s cup melted. The first time I put the cup in right when they came out of the oven and the second I waited about 5 minutes and they still melted. What am I doing wrong!?
The Reeses will melt initially from the heat. There’s no way to prevent that. But if you leave them in place and don’t mess with them until the cookies are completely cool, the Reeses will cool too and be just as they were when you added them – nice and firm.
Is the butter unsalted or salted? This recipe looks great!
I used salted.
So impressed with this chocolate cookie recipe. It looks so delicious and beautifully captured.. pinned!
Question – you list milk in the instructions (#3) but it is not listed in the ingredients. I am making this now and noticed that but will do it without milk since I don’t know how much to add…hopefully they still come out okay.
You were right to leave it out – sorry about that. I’ve updated the instructions. Thanks Stacey!
You know I love me some peanut butter chocolate!
Now that Halloween is over, and I have done my traditional buying way more candy than we needed, recipes for delicious ways to use up that candy are just what I need! 🙂 Its just a coincidence that I buy candy that bakes well 😉 Now my Reeses cups are taken care of. Without icing, I think these would freeze really well for use on holiday cookie platters!
these look so tasty! love these photos too!
I need to make these ASAP, they look delicious! Pinned 🙂
And Happy Halloween!
I love stuffing Reese’s peanut butter cups into peanut butter cookie cups but chocolate sounds equally delicious! Plus, it’s Reese’s peanut butter cups and you can never go wrong with those.
I’m super lame with Halloween costumes. My husband and I dressed up as patriots players one year just so we could wear those football helmets that you attach your beer cans to and drink two cans at once through a straw. We’re classy like that.
Reese’s will always be number one in my book! Have a great Hallowen
You are Michael Jackson is TOTALLY cracking me up! Love that.
I was a hippie for like 10 years straight. I’m creative like you.
And these cookie cups? You are the queen of cookie cups…I need these in my face! Pinned!
Oh man, do I want to sink my teeth into these!! Happy Halloween Lindsay! 🙂
Yep. You’ve won the prize for my favorite Halloween day blog post! Reese’s HAS to happen today, but in this form it’s beyond my happiest dreams. Thanks for posting such an amazing recipe!
