Peanut Butter Cup Crack Brownies

Peanut Butter Cup Crack Brownies | Cookies and Cups

Peanut Butter Cup Crack Brownies are completely over the top in the best way possible! Soft, fudgy brownies, with a layer of peanut butter cups, topped with a thick crispy peanut butter chocolate layer!

These Peanut Butter Cup Crack Brownies are the dessert you should bring to any event where you want to seriously impress people. I can’t even begin to describe their deliciousness. They are consistently one of the most popular recipes on my website for good reason, EVERYONE LOVES THEM!

So I started with a box of Ghirardelli Double Chocolate Brownies… they are some of my favorite boxed brownies.

While they were baking I chopped up some peanut butter cups…

Then I chopped up some peanuts…

When they’re done pull them out and using an off-set spatula, spread them all over…

Then melt some chocolate chips, peanut butter and butter in a bowl…stir in some vanilla, salt and krispie cereal…

When they’re set up you can dig in.
The foil makes the whole situation easier, so don’t forget to line your pan before you bake your brownies…

      Yep, Pull them out when there is about 5 minutes left on the baking time, sprinkle the nuts and pb cups on top and place them back min the oven for 5 minutes to melt the chocolate, so you can spread it.

  1. I put something kind of like these in my book! I skipped the peanuts but they’re such a good blend of chewy, crunchy, gooey, chocolate, PB…pretty much covers it all. Your bars are making me hungry πŸ™‚

  2. Serious question here: I’m very curious as to what the food bloggers, especially the baker’s, do with all the treats they make? I’m assuming your neighbor’s love you. If I baked all the time I wouldn’t fit through the doorway!

    These brownies look fabulous, by the way!

      1. Kristen

        I bake for my husband (LT), son’s (dispatcher) and local police departments! Plus my co-workers and doctors offices love them too!

  3. Holy cannoli! You’re killing me here…I stupidly started a diet on Monday and I want these in a bad way. I’ve pinned for when I cave (which will probably be pretty soon. I have no will power.)

  4. You crack me up. Every time you post something. And everything you post is mouth-watering. And it could be because of you, that my scale is heading upwards… And quite frankly, I’m okay with that! I can not WAIT to try these! Thank you!

    1. shelly

      You could, but the chocolate layer on top might be a bit too thick. If you use the 8×8 I’d cut the chocolate back to 1 1/2 cups and the pb back to 3/4 cup!

      1. Cut Back? That is a sacrilege to this recipe. I want to know if doubling it would work well in a 9 x 13 x 2 baking pan. I would try it but I am an inexperienced baker and would hate to waste a lot of expensive ingredients on an experiment. This recipe sounds great!

        1. shelly

          What I would do is buy a brownie mix that is “Family Sized” which will work perfect in a 9×13…
          The other ingredients, I would increase the chocolate chips by 1 cup and the peanut butter by 1/2 cup, and the krispie treats by 1/2 cup. I don’t think you could mess it up!
          As for the pb cups and peanuts, just throw in a few more, no need to be exact for this πŸ™‚

          1. Thanks Shelly for your prompt reply. I shall be trying this recipe adjustment out within a couple of weeks because I am going to be attending a “Potluck” gathering and I think that these brownies will blow them away. πŸ™‚

            I really do appreciate your blog and I will be following it regularly because your recipes look awesome

    I made these last night and my girls and I just tried them-OMG! We’re in a sugar coma now, and it’s totally worth it. I’m taking these to a dinner tonight, and I’ll be surprised if any of them make it home!
    BTW, I made these in an 8 x 8 pan, and didn’t reduce any of the recipes. They still turned out great…look forward to trying more of your recipes.

    These look AMAZING!

    The pan size has been discussed already, but I wanted to clarify: the original BHG recipe calls for a 9×13 pan. So you just opted for the 9 inch pan and kept everything else the same, right? Did you really get 25 out of a 9 inch pan?

    1. shelly

      Well, I cut them small, because they are a little thicker. I tweaked some of the ingredients in the BHG recipe slightly to suit my taste, like adding more krispies…but I just prefer a thicker brownie!

  8. Made these, INSANELY GOOD! They rocked, I rocked them. I bumped the recipe up by about 50% to accommodate a 9×13 pan and used my go-to non-mix brownie recipe and despite cooking them at 350 instead of 325 for 35 minutes which made them weird like crumbly cake they were still awesome. I can’t wait to try them with proper brownies for the base!! You rock girl! Crack is a good name!

  9. Mindy

    OMG these are so incredibly WONDERFUL, I’ve made them 3 times because after I made them the first time everyone requests them !!! Just made them again this morning and noticed the last ingredient is kosher salt (somehow I have missed this every other time I’ve made them) but I don’t see where to add it. Do I sprinkle on top ? Or add to the krispie mix ?

  10. dina

    question- i have the mini reeses. do still do 12 or should I add more?
    funny I didn’t read all the comments before sending my hubby to michael’s to get a 9×9 pan. I hope to get reply before baking?
    Thanks, Dina

  11. sooooo, i have finally managed to round up all of the ingredients for this. they are patiently sitting in an Asda bag in my cupboard… hopefully tonight will be the night!

  12. Barbara

    I had to come to your blog to read the complete instructions. somebody passed just the recipe to me and you don’t say what to do with the salt. I found it when I read the blog post, line by line, but you might want to add that to the “How to Make” section of the recipe. I have made these already without the sale (since I didn’t know where to put it)… and they were DIVINE! Everybody wants the recipe!

  13. Why is it peanuts and chocolate go so well together? Great photos, I didn’t even get down to the ingredients list before drooling uncontrollably.

  14. First, “Let that situation cool.” Haha…I love your way with words, Shelly.

    Second, OH my gosh! Do you seriously want me to be 400 pounds? My thighs rub together already! But, I think I’ll take a little extra inner thigh fat for these babies. Need to start getting ready for winter, you know. πŸ˜‰

  15. Nanette

    These look as evil as my bodacious brownies, I have to try these I like the rice crispies in there, that is interesting. I may add some instant espresso like mine have for that extra buzz!!!

  16. Nicole

    Just made these and forgot to put the peanuts in with the Reese’s. Soooooo … I chopped them and put them on top instead. It’s cooling in the fridge and I’m sure it will be fine AND it looks so pretty. πŸ˜‰

  17. Donna Howard

    Can’t wait to make these tomorrow. But I’m just curious, what’s the difference with the family sized box of brownies (of course I looked at what I had and that was ALL I have!!) I could get another box tomorrow but I was just curious. Thanks so much Shelly and love love love your blog and ‘low calorie’ (ha ha) recipes!!

  18. Anne Coffman

    Just made these tonight and the picture looks like much less topping than I had. The ratio of topping to brownie/cups is more than 2:1. I’d make them again but cut the topping in half so you taste the brownies more. Thanks- great sugar buzz!

  19. I am a little confused about using that much salt. Also I can’t find where it is to go. Do you add it to the chocolate chip part ? Maybe using 1 teaspoon of salt is a typo ?

    1. Shelly

      You can add 1/2 tsp if you think that you might not like the salt…it’s all personal preference. I like the salty in my sweets, so I tend to add more. Start with less and add more if you feel necessary. Also, I added it when I added the vanilla and cereal. I adjusted the recipe to read more clearly on that! Thanks!!

  20. Jessica

    i made these for a bbq. I set them out and within a few minutes they were gone. Everyone raved about them and if there was an award for best dessert these would likely have won. Super easy, will definitely make again!

  21. Samantha

    These are UNREAL. The best brownie/bar/chocolate/peanutbuttery thingy I have ever made! However, addicting? beyond addicting. Also, I think my recipe builder put these bad boys out at about 600 calories per square! Worth it? YES.

  22. KarenB

    When I first looked at this picture someone shared on FB, I thought it was brownies, peanutbutter cups and then No Baker Chocolate Oatmeal cookies spread on top. Can you IMAGINE? I WILL be making these for our next Sunday dinner at my daughters

  23. Celeya

    Who ARE YOU??? OMG these are a DREAM COME TRUE!!! Perfect in every way!!! My fav brownie mix too! Reese’s eggs ARE THE BEST! Somehow they just seem more peanut buttery. Looks like you cut off the edges of the brownies so they are PERFECT!!! I LOVE YOU!!!

  24. Debbie Smith

    Made these this past weekend, and they were AMAZING! I want to know if I can double the recipe and put it in a 9 x 13. Have you ever tried this?

  25. Erica Esser

    These are really good, but in my opinion the top layer is way too thick. I could see from the photos that it would be, so I intentionally used a 9×13 brownie mix (and 6 extra peanut butter cups) to spread out that top layer a bit. I like the top layer as an accent to the brownie layer, but this just overpowers it, even with my adjusted ratio. Next time I will halve the part of the recipe for the top layer.
    Thanks for the recipe!

  26. Pauline

    YUM! YUM! YUM! OMGOSH! These were delicious!!! Thank you for sharing the recipe. I made them in a 13×9, and switched the salty peanuts for unsalted walnuts

  27. Rylie Baker

    Made these today. MY NEW FAVORITE BROWNIES! These are seriously amazing! I can’t stop eating them. I left out the peanuts but chopped up snickers and mixed that with Reese’s instead. So good. I’ve never left a comment before on any site but these were too good not to. Thanks for sharing! πŸ™‚

  28. Rylie Baker

    BEST BROWNIES IVE EVER HAD! I just made these the other day and could have eaten the entire pan by myself. I used snickers in place of the peanuts. Other than that I followed the exact recipe and they turned out amazing. Seriously these are my new favorite brownies. Thank you!!

  29. Jessica

    Hi Shelly! I’m making these tonight with a friend for the first time! I’ve wanted to make them forever, but always wanted a good “reason”. Well my friend and I decided who needs a reason! Can’t wait to try them!

  30. Linda

    Made these for our Daytona party today and they were a huge hit! Everyone agreed that that dry roasted peanuts help keep them from being overly sweet! I came home with an empty plate an many compliments. Thank you for sharing this great recipe!

  31. Krystal

    I don’t know if I can forgive you for these, they are so good. I saw this recipe on Facebook and made them, making sure I put together a little bag for a friend who loves peanut butter cups as much as I do. I took a bag for my friends in a fishing trip, and a bag for my friend. Both bags were eaten. Guess my friend is SOL. Thank you for this evil!

  32. Linda

    I have found that whenever I mix crispy cereal with melted chocolate chips, they get soggy. Does anyone have a tip on how to keep them crispy? What am I doing wrong?

  33. Meg

    Are these better with the peanut butter cup eggs or regular peanut butter cups?? With it being “egg” time of year and them being out I was curious which would be better! Making for a get together this weekend πŸ™‚

  34. Sharon

    Just made these for a potluck with my choir. Fantastic! I knew I had to try them but didn’t trust myself to have them in the house. I thought about making them in a 9 x 13 pan so they’re not so thick.

  35. PizzaG

    I made these but didn’t care for them. The peanut butter/chocolate chip/crisp rice topping was way too thick for my liking and that of my family. If it had been half or a third, maybe that would have tasted better for us. I found myself slicing most of it off when I would cut a brownie square. Sorry but it just wasn’t for me.

  36. Nancy

    I don’t have any PB cups and can’t get out to get any, but would like to make this for a “Thank You” treat. Do you think that I could somehow use PB for that layer (maybe mixed with a little confectioners’ sugar (if thickening is necessary, for example) ? If you think that this might work and could give me an idea of how much PB to try, I’d appreciate it!

  37. Cindy

    Funny how all these recipes always start with a boxed mix. If you’re really cooking or baking, why can’t you make a simple brownie or cake recipe? Just because we like sweets doesn’t mean we like the junk that passes for ingredients in packaged foods.

    1. Shelly

      You can certainly start with a scratch brownie recipe if that is what you prefer. It’s certainly a personal preference.

  38. Melanie

    I have boys that stay with me, ages 19 and 32 and always have strays that show up too. I am gonna make their day when they I make these!! They look AMAZING!! Thanks for the recipe!

  39. Michele

    I hope this question has not been asked already. So many comments and not enough time to read them all right now.
    I assume you used full size peanut butter cups and not the minis. Did I assume correctly?

  40. Lori

    These are AMAZING! had them at a party and immediately had to try it myself. everyone who had one LOVED them! The peanut and chocolate layers are so delicious, I want to try it without the brownie layer next time. Has anyone tried this? was it successful?

    Disappointed this recipe was a disaster for us, the Reese did not melt and the peanuts burned… I may try it again using the reese pb chips mixed with milk chocolate chips and no peanuts…
