Peanut butter cups will get me every time. #addictedtopeanutbutter

When I turned peanut butter cups into peanut butter cup cookie bars? Yeah…also #addictedtopeanutbuttercups.

Peanut Butter Cup Cookie Bars are like a peanut butter cup in bar cookie form!

Okay, so before we get into todays post and how these awesome peanut butter cup cookie bars are like She-Ra, I want to wish my mom a Happy Birthday. Today is February 15th and today my mom turns 29! Wait… 😉 Anyway, happy birthday mom, I love you!

Oh, and Mom? Sorry I didn’t give you any of these bars. I made them back in January. But your birthday cake made up for it right?

{Don’t worry, I’ll be posting that recipe soon. You’ll all be thrilled, I pinky swear.}

Peanut Butter Cup Cookie Bars

So, how are these cookie bars like She-Ra? Remember how she used to go hold up that sword and proclaim “I AM SHE-RA!” and turn from an ordinary girl into a kick-ass chick with super powers? Then she’d fight for goodness and truth and save all the people of Etheria with the help of her horse Soft Wind that turns into a pegasus.

{Pretty much, if you’re under 30 or over 45 you have no idea what I’m talking about. Come on thirty-somethings. You know what I’m talking about, right? She-Ra, the female version of He-Man?}

Anyway, these cookie bars are like She-Ra because they’ve been transformed. A lowly peanut butter cup, akin to Princess Adora, performed some mystical magic and turned itself into a cookie bar. Get it?


Peanut Butter Cup Cookie Bars

{Seriously, you guys. Was I the only little girl obsessed with She-Ra? I have a VHS tap of Secret of the Sword in my garage. It’s too bad I no longer have a VCR.}

Alrighty, let’s talk about cookie bars. These? Are thebombdotcom. They’re the juggernaut of all cookie bars. They’re a bar that tastes like a candy. Let’s break them down:

Layer 1: A dark chocolate cookie bar. I used my Oreo cookie recipe to make the base of these bars. (That was a good decision.) If you’re not a fan of dark chocolate cocoa, or you can’t find it (I used Hershey’s Special Dark), you can use regular unsweetened cocoa.

Layer 2: Peanut butter. This layer is pretty simple: peanut butter, powdered sugar, and vanilla. The sugar sweetens the peanut butter and makes it easier to spread. Use your favorite kind (y’all know I love me some Skippy Naturals!)

Layer 3: Melted chocolate and peanuts. The melted chocolate frosts the bar and the peanuts add a nice crunch. I added some Crisco to my chocolate to help it melt, but you can use vegetable oil instead. And I love Trader Joe’s Honey Roasted Peanuts but you can use whatever kind you like best!

A note on cutting: similar to when I made these peanut butter pretzel bars, and these Tagalong Bars, you don’t want to cut these bars when they’re cold. I let the chocolate harden for several hours on the counter, which worked because it’s winter. In the summer (of if your house is warm), I would need to chill them to harden the chocolate. Just make sure to let them come to room temperature before cutting or the chocolate will splinter.

Chocolate cookies, peanut butter, chocolate, and peanuts. 4 things that should always go together.

Like She-Ra and He-Man. 🙂

Peanut Butter Cup Cookie Bars

Chocolate cookie bars topped with peanut butter filling and chocolate. Like a peanut butter cup in cookie bar form!


  • 1/3 cup unsweetened cocoa powder (I used Hershey’s Special Dark)
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 1/4 cups all-purpose flour
  • 1/2 cup butter, softened
  • 2/3 cup brown sugar
  • 1/4 cup granulated sugar
  • 2 teaspoons vanilla, divided
  • 1 large egg
  • 1 cup peanut butter
  • 1/2 cup powdered sugar
  • 1 (11-12 ounce) bag chocolate chips (milk or semi-sweet)
  • 2 teaspoons Crisco or vegetable oil
  • 1/2 cup chopped peanuts


  1. Preheat oven to 350°F. Line a 9×13” pan with foil (for easy removal) and spray with cooking spray.
  2. In a medium bowl, whisk together cocoa powder, baking soda, salt, and flour. Set aside.
  3. In the bowl of an electric mixer fitted with the paddle attachment, cream butter and both sugars. Mix in egg and 1 teaspoon vanilla and mix until smooth. Add dry ingredients and mix until combined.
  4. Spread cookie dough in prepared pan. Bake for about 17-19 minutes until it’s no longer shiny. Cool completely before continuing.
  5. Mix peanut butter, powdered sugar, and 1 teaspoon vanilla with a hand mixer until smooth. Spread over cooled cookie bars.
  6. Place chocolate chips and Crisco or oil in a medium sized bowl. Heat on high heat in the microwave for 30 second increments, stirring between each, until melted and smooth (about 1 1/2-2 minutes). Spread over peanut butter layer. Sprinkle with chopped peanuts.
  7. Let harden for several hours. You can chill the bars to make the chocolate harden faster, but be sure to let them come to room temperature before cutting so that the chocolate doesn’t splinter when you cut them.
  8. Store in an airtight container for up to 5 days or freeze for up to 1 month.

  1. Oh my, these look too good to be true. Just trying out  a healthy cookie recipe right now (in the oven as we speak) but now that I see this I think… what’s the purpose of leaving sugar and butter out again? Looks amazing, lol 

  2. I had totally forgotten about She-Ra. Now I’ll be hunting through YouTube instead of shoveling snow…
    So you’ve gotta know this is my happiest place, Dorothy! I love anything with PB. Put Oreos in the mix and I am seriously hiding with these in a closet for an hour away from my kids!

  3. Sorry, never heard of She-Ra! But, I have definitely still got some VCRs in the attic but no player to play them with. These bars look out off this world! The peanut butter layer on top of that cookie base makes me want to reach through my screen! 

  4. All these layers, flavors, textures, all in one bar. Each bite has got to be just perfect. And with PB and chocolate, well, I know it’s perfect 🙂

    And don’t you hate it when chocolate sets up too firm and it cracks upon cutting it – so I read your ‘note’ while nodding. I have ruined more ‘pretty desserts’ that I was all set to photograph with cracked chocolate than I can even tell you…LOL

  5. Whoa, these bars look seriously amazing and totally irresistible! I love the smorgasbord of textures!

  6. Wow those look insanely good! So many layers to love 🙂

  7. I loved She-Ra and wanted to be her! He-Man was just her wannabe! Awesome bars!!

  8. These look incredible!  I totally get it 🙂 I was all about she-ra and Jem. This were my girls. Although I secretly liked the misfits better than the holograms

  9. These cookie bars look amazing! I love anything with PB & chocolate!!

  10. Dorothy – These will satisfy all of my peanut butter cravings. I love the idea of adding honey coated peanuts to the top. Sometimes, regular salted peanuts don’t do anything for me. 

  11. These look killer!!  I literally just looked at the first picture and started drooling!!  I love pb and chocolate!  Great job!

  12. These look amazing! Have you tried the new Reese’s chocolate peanut butter spread? It is sooo good. Sounds like something you would like. I could eat the whole jar in one sitting. 

  13. This look amazing! So tempting for a 9 month pregnant woman!

  14. Dorothy…these look AH-Maz-Ing! I so love dark chocolate brownies and cookies and cake…the fact that the base of this is almost coal black is beautiful…and balanced with the sweet peanut butter and chocolate…then topped with chopped nuts? Too good!

  15. Totally the story of food blogging life… Making desserts weeks or months in advance, then having friends and family ask if they can have a taste as soon as you post them. (That’s what freezers are for, right? Although I should probably put a lock and key on mine so I don’t eat all of the chocolate desserts…) Happy birthday to your mom!!

  16. Thanks for the birthday wishes…again! These do look amazing but then again, so is my cake (and pretty much everything else you make). Love you too! xoxo
    btw, we can transfer VCR tapes to a DVD on our machine unless it’s protected!

  17. I am a sucker for anything peanut butter and chocolate. These cookie bars look amazing! I MUST try them soon.

  18. Goodness, these look amazing. I’m loving that you used honey roasted peanuts. SO MUCH BETTER than regular! Definitely pinning, because I just may have to try these asap! 🙂

  19. Happy happy birthday to your mom 🙂 These bars look beyond incredible, all those layers are perfect! Love the dark chocolate and peanut butter combo!

  20. Sigh now I am craving an entire tray of these this morning.  Look what you made me do!

  21. I was She-Ra obsessed too! My brother and I always watched He-Man and we had all the toys. I was always Skeletor, but it was awesome. Thanks for sparking some really great childhood memories. Don’t forget Jem too! 😉

    PS…those bars look delicious!

  22. you had me at thebombdotcom. 😛 and I loved She-Ra too!!! oh my gawd, blast from the past. .  keep the peanut butter desserts coming. .  love it ..  peanut butter is my comfort food. .  that’s how I got through high school . .  with my spoon and jar of peanut butter.  . which I would eat at home. By myself 😛 and I may have eaten too much but whatev’s

  23. Okay, cut the ridiculousness. We live 2 minutes away and I didn’t even get ONE of these bars?! BRB, crying. But seriously, they look AMAZING! 

  24. Each layer of these bars just look and sound so incredibly delicious Dorothy. You totally have me drooling over the images and your description of them!

  25. I loved She-Ra! I’m glad they haven’t brought her back and ruined her look, as they did with My Little Pony! At least, not to my knowledge! These bars look awesome! 

  26. Yes, She-Ra was awesome!!!  I had totally forgotten about her…thanks for the fun blast from the past!!!  And these cookie bars are epic!!!  I would love to shove about 6 in my mouth!!!

  27. I am addicted to peanut butter cups too! These look incredible!
