Peanut Butter Cup Cookie Bars

Peanut Butter Cup Cookie Bars from

Cookie Bars are loaded with miniature peanut butter cups and finished with a chocolate and peanut butter topping. Cut them into fun sticks for dunkable dessert!

It’s not Fall in our house until we’ve made a trip to Bath & Body Works for ALLTHEFALLTHINGS. Between hand soaps, wallflowers, and of course, loads of candles – we’re officially stocked up for the season and then some because I’m a Fall scent hoarder. No joke.

Although I’ve been yearning for Fall weather, it’s just not happened yet. It’s been hot, humid, and spidery. I’m fully aware that spidery is not a legit weather word, but spiders totally creep me out. And their webs, don’t even get me started on those things.

With Elle hanging out on the floor so much, I feel like I am on constant spider patrol.

I’ve read that dousing your house in peppermint oil works – has anyone tried this?

I think I need to invest in one of those forehead miner-style lights to look under the couch and other dark places where those terrible arachnids lurk. Sure I could use a flashlight, but a miner light will totally bring a little comedy to my anxiety. You probably think I’m kidding, but I’m so serious.

Peanut Butter Cup Cookie Bars Recipe from
Enough creepy spider talk, let’s discuss mini peanut butter cups. Have you noticed this miniature candy trend? I swear Target has half an aisle dedicated to bags upon bags of itty bitty candies. These little things are completely addictive in the best of ways. The only problem is that I’m fairly certain I consume way more calories popping these tiny bites of candy bliss than I would if I simply ate the full size bar.

A few weeks ago I purchased a few bags of them while at Target which ended up being a very bad idea for a girl that’s trying to lose baby weight. The bag of Miniature Reese Cups stared me down for days until I finally had to bake them into something!

Peanut Butter Cup Cookie Bars come together in just minutes. They’re definitely scrumptious on their own, but slathering them with a chocolate and peanut butter glaze pushes them to over-the-top awesomeness!

They’d be great as an after-school treat, or as a take-along to the first school party, if you’re allowed to do that. If you’re not, I happen to know personally that teachers are ALWAYS allowed home baked goodies, and they truly appreciate them. I’m just sayin’, a plate of these bad boys might just go a long way in making your kid’s teacher a little happier at the end of the work day.

Whatever you do, bake them immediately!

Peanut Butter Cup Cookie Bars

Yield: 12 servings

Prep Time: 15 minutes

Cook Time: 20-25 minutes


1 cup all-purpose flour
1/2 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon salt
1/3 cup unsalted butter, melted
1 cup packed light brown sugar
1 large egg
2 teaspoons pure vanilla extract
1 cup mini peanut butter cups

For the Chocolate-Peanut Butter Glaze

3/4 cup semisweet chocolate chips
3 tablespoons creamy peanut butter


1. Preheat oven to 350 degrees F. Line an 8x8-inch baking pan with foil and spray with non-stick cooking spray.

2. In a medium bowl, combine flour, baking powder, baking soda, and salt.

3. In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with an electric mixer, combine the melted butter and brown sugar. Add egg and vanilla, mixing until well combined. Gradually add in dry ingredients and mix until just combined. Stir in mini peanut butter cups.

4. Spread the batter into the prepared pan. Bake in the preheated oven until a toothpick inserted in the center comes out clean, about 20 to 25 minutes. Remove pan to wire rack and cool completely.

5. In a medium, microwave-safe bowl, melt the chocolate chips and peanut butter on 50% power, stirring every 30 seconds, until completely smooth and melted. Spoon the mixture over the cooled cookie bars and spread into an even layer with an offset spatula. Refrigerate for at least 30 minutes, or until set. Remove from pan and cut into bars.


Peanut Butter Cup Cookie Bars can be stored in an airtight container at room temperature for up to 2 days.

    Eeeek spiders!! I don’t think I could sleep in our apartment if I knew there were spiders lurking about! I know there probably is most of the time, but ignorance is BLISS! Reece cups are one of my favourites! Definitely got to try this :)

      Can you tell me if the peanut butter cups are the unwrapped minis or the miniature peanut butter cups that are wrapped?

    • Jamie — October 18, 2014 at 5:47 pm

      The are the unwrapped minis – I hope this helps! :)

  14. Jennie @themessybakerblog — September 11, 2014 at 8:48 pm

    It’s still hot here, too. I really want to wear my boots and new comfy sweater. I recently made a trip to B&BW for fall scents, too. And, I stocked up at Yankee on $1 tarts. These cookie bars look amazing. I want to dunk them in my coffee.


    • Jamie — September 12, 2014 at 4:22 pm

      Thanks for visiting Jennie!


  15. Joy — September 12, 2014 at 12:58 am

    Unfortunately we don’t have the miniatures is Australia, only regular size. Do you think I could use them some way?


    • Jamie — September 12, 2014 at 4:22 pm

      Hi Joy,
      I think you could cut the regular size into quarters and it would would fine. I hope this helps!


  16. Dana @ Wanted Adventure — September 15, 2014 at 11:29 am

    There was no WAY I could visit this site without reading this post about Peanut Butter Cup Cookie Bars. It’s more of a tease, though, because I live in Germany and have never seen mini peanut butter cups. JUST recently I saw regular peanut butter cups in one single store–I bought a bunch, but have already eaten them all, and now they’re not selling them anymore!! But hopefully they’ll come back, or I’ll just stock up next time I’m in the States :D

  19. Jocelyn — October 1, 2014 at 1:36 pm

    Hi There! What do you suggest I use if I don’t have a stand-up mixer?? Would a hand mixer work on low?


    • Jamie — October 1, 2014 at 9:24 pm

      Hi Jocelyn,
      Your hand mixer should work just fine. Thanks for stopping by.


  20. Sue — November 2, 2014 at 8:59 am

    Hi, these look delish, can these be done by hand and not a mixer as I don’t have either.


    • Jamie — November 4, 2014 at 3:40 pm

      You can mix these bars by hand. Thanks so for stopping by.


  21. debbie — July 7, 2015 at 11:59 am

    8×8 pan. sorry, that’s just not enough! LOL could i double the recipe and use a 9×13?


    • Jamie — July 7, 2015 at 1:04 pm

      Hello! I haven’t attempted to double the recipe in a 9×13, but I think it would work just fine. You may end up with slightly thicker bars – which couldn’t possibly be a bad thing! :)

  22. debbie — July 7, 2015 at 3:05 pm

    LOL…nope, not bad at all! thanks for your reply, Jamie:)


    • Jamie — July 7, 2015 at 3:18 pm

    I found this recipe on your Pinterest page in December, 2015. Wanted to make something chocolatey/peanut buttery for my cousin who was coming for Christmas. These bars are TERRIFIC!! Everyone LOVED them and is very easy to make. 

    I’m remembering this experience today, on Valentine’s day, to make them again for my boyfriend, who loves those chocolate/peanut butter. I know it will be a hit. Thank you so much for a decadant recipe!


    • Jamie — February 14, 2016 at 12:53 pm

    Can I substitute the peanut butter cups with nuts?


    • Jamie — December 15, 2016 at 12:29 pm

      Hi, Maria! You absolutely can substitute nuts! I hope you like the bars!
