Peanut Butter Cup Crunch Brownies

A sinful brownie layer, topped with peanut butter cups and a peanut butter fudge crispy layer on top. 

These peanut butter cup crunch layered brownies are out of this world!Sorry to bombard you with a sugar chocolate bomb like this after sharing that Skinny Peanut Butter Pie earlier this we…

Wait.  I’m not sorry.

When homemade fudgy chocolate brownies, peanut butter cups, salty peanuts, more chocolate, more peanut butter, and rice krispies come together… well, you know it’s gotta be good.  Three layers of bliss.  Chocolate, peanut butter bliss.

“Better than crack” as some call it.

Begin with a dense chocolate brownie base.  My homemade brownie recipe is your standard fudgy, chewy brownie.  Tastes like fudge and chocolate frosting in one.

You can always use a boxed brownie mix for the bottom layer.  Whatever floats your boat.

Next, we have a shower of chopped Reese’s peanut butter cups (or mini Reese’s cups, whichever you prefer) and salty peanuts.  The peanuts are amazing – gives each bite a nice crunch.  Plus, WHO doesn’t love salty & sweet?!

The Reese’s peanut butter cups tucked inside are obviously necessary.  And so completely sinful.

For the top layer… my personal favorite… a melty mess of peanut butter, chocolate chips, and Rice Krispies. I couldn’t stop “tasting” this layer.

So, I brought these crack brownies to a BBQ over the weekend and silently placed them on the dessert table.  I listened quietly at the comments.  They made my day. 🙂

“WHO made these?”

“What are they!??”

And my favorite, “I can’t speak. This is the best thing I’ve ever eaten.”

Trust me.  If you like chocolate at all, you have GOT to make this.  Your life will be forever changed.  You’re welcome.

Description

A sinful brownie layer topped with peanut butter cups and a peanut butter fudge crispy layer on top. 


Ingredients

Homemade Fudgy Brownie Layer

(or use your favorite boxed brownie mix)

  • 1/2 cup (1 stick) salted butter
  • 8 ounces coarsely chopped bittersweet (or semi-sweet) chocolate (I used two 4 oz Ghirardelli Semi-Sweet Chocolate Baking Bars)
  • 1 and 1/4 cups granulated sugar
  • 3 large eggs
  • 1 teaspoon pure vanilla extract
  • 3/4 cup all-purpose flour (spoon & leveled)
  • 1/2 teaspoon salt

Middle Layer

  • 3/4 cup salted peanuts
  • 8 full size Reese’s Peanut Butter Cups, chopped

Top Layer

  • 1 and 1/2 cups semi-sweet chocolate chips
  • 1 and 1/2 cups creamy peanut butter
  • 1 Tablespoon unsalted butter
  • 1 and 1/2 cup Rice Krispies cereal

Instructions

  1. If using a boxed brownie mix, prepare the brownie layer according to packaged directions. Bake the brownies for 5 minutes less than the recipe states. Skip down to #3.
  2. If using my homemade fudgy brownie recipe: preheat oven to 350°F (177°C). Generously spray 11 x 7 inch baking pan with cooking spray or line with aluminum foil. Set aside. Melt butter and semi-sweet chocolate in a medium saucepan on medium heat, stirring constantly (about 6 minutes). Remove from heat and stir in sugar. Add in the eggs one at a time, whisking until smooth after each addition. Whisk in the vanilla. Gently fold in the flour and salt. Pour batter into prepared pan, smoothing the top with a knife. Bake for 30 minutes.
  3. Remove brownies from the oven and sprinkle the top with the peanuts and chopped peanut butter cups. Return to the oven and bake for 5 additional minutes.
  4. While the brownies are finishing up in the oven, melt the chocolate chips, peanut butter and butter in a medium saucepan over medium-low heat. Stir in the Rice Krispies cereal until evenly coated. Remove the brownies from the oven and pour the chocolate and peanut butter mixture over top. Spread to cover evenly. Refrigerate for 2 hours before cutting into 24 squares. Cover tightly and store in the refrigerator for up to 3 days.

    1. I know! I’ve made them before when I first saw Jessica’s post! They really are too good to be true. Amazing. Thanks Aimee 🙂

    2. Hi Sally,
      Have been dying to make these for a long time. As I cannot get the peanut butter cups in Denmark – can you recomment a substitute???
      Neel

      1. Hey Neel! You could try leaving the pb cups out all together. Instead, try using peanut butter baking chips, another chopped up candy bar, or chocolate chips. Thank you!

  1. I can’t believe we were just talking brownies and you had this little trick up your sleeve! I’ve made similar brownies and they are so amazing. I love the top layer with Krispies/PB – something about it is just so addictively perfect! And I bet you were most definitely the talk of the party when people sunk their teeth into one of these babies! And all your recipe recaps are calling my name – espi the other choc brownies with that dense PB layer on top!

    1. Hey Averie! After you sent me that brownie email, I went back and reviewed my go-to brownie recipe, I’m totally intrigued by yours now though! I’m glad you mentioned my related recipe recaps – sometimes I feel like they go unnoticed. But I love how you feature yours and it brings old recipes back to life! the top layer of these was definitely my favorite!

  2. Yum! I love that delicious crunchy top as the “hat” for these super fudgy brownies. I’m with you–butterscotch and blondies all the way, though I *did* have a brownie hankering last night and it *did* roll over into this morning, so methinks I’m making your homemade fudge brownies tonight for dessert. Blondies are awesome, but freshly baked, super fudgy brownies? Those are just killer!!

    1. you have to make these fudge brownies… even if you don’t layer them with the pb cups and peanuts and pb/chocolate krispie “hat” (hahaha love it)… they are so rich and fudgy on their own! You’d love them Hayley 🙂

  3. These are probably in my top 5 fave desserts ever. I posted a recipe a few months ago and despite not having pb cups like yours do, they are incredible! You are right about that top layer….the best! Ok now I need to make these again – but with pb cups this time!

    1. definitely a top 5 dessert for me too, Stephanie! You have to try them with pb cups next time. The little pb cup surprise in each bite is to die forrrrrr.

    1. I love a ton of texture too.. I couldn’t keep my hands off of these as I was cutting them into squares. you’d love these mercedes!

  4. Mmmm I made these once! “Better than crack brownies”…. they definitely lived up to their name 🙂

  5. Peanut butter and chocolate is my favorite combo! Seriously, just when I think you can’t come up with a better recipe – you do 🙂 Thanks for sharing, Sally!

  6. Oh my goodness, your treats + sweets seriously get better every day. Peanut butter + chocolate = heaven, + these look AMAZING!

  7. Nice to meet you, Sally. I found your site through Haley at The Domestic Rebel. These brownies look delicious and I’m glad the attendees at the barbecue loved them too!

  8. Oh my, these are way too decadent, in the best way possible. I’m breaking out my stretchy pants for these babies. You’ve outdone yourself yet again!

  9. OMG – I did not need to see these right now! I don’t really mean that. I’m lusting after these so badly Sally! You’ve outdone yourself. I’ll be dreaming of them!

  10. Yes, pb cups are absolutely necessary in almost every treat!!! You are my pb treat girl…I can always count on you to deliver an awesome decadent goodie!!! I love that you silently put the bars on the table at the bbq and then just listened. Haha totally something I would do too:-)

  11. I just made your crack brownies and just read I have to wait 2 hours before diving into them?!? These look and smell aahhmazing!! Can’t wait to eat half the pan..err..I mean one 🙂 thanks for the great recipe!!

    1. Samantha – yay! I love these brownies so much. Yes, the waiting time is the hardest part! I know you will lvoe them though – worth the wait!

  12. Made these this week and they are AMAZING! I (embarrassingly) completely forgot the vanilla and they were still good! Another winner, Sally 🙂

  13. I made these today for my familys “first day of preschool celebration dinner dessert.” I didn’t have peanuts so I substituted walnuts and no rice krispies so I substituted crushed up kix. I asked “how are the brownies?” and my husband said “these are the best brownies you have ever made!” my boys couldnt even form words they only mummbled through chocolate fudgy mouthes “mmmmmm.” WINNER!!! This is the third recipie I have made from your site in the last two days and each and every one has gotten rave reviews from my family.

    1. Melanie, that is SO great! And the substitutions you made are perfect. I’ve used crushed up cornflakes instead of the Rice Krispies, never Kix though. I think it’s pretty tough to not like these brownies – no matter what little substitutions are made. Thank you so much for letting me know how much you are all enjoying the recipes.
