Rice Krispie & Peanut Butter Cup Brownies

Rice Krispie & Peanut Butter Cup Brownies

The first rule of entertaining: always stash some for yourself.

Especially when it comes to dessert.

Because after the crowd of tipsy beer-fanatics have their way with the dessert tray, there won’t be a solitary crumb left.

In hindsight, perhaps this particular dessert wasn’t the best choice for an outdoor gathering that day, considering the humidity had to be at least 327% (in other words, downright sticky). But the fact that the topping was melting all over everyone’s hands didn’t stop them from devouring the whole tray.

Rice Krispie & Peanut Butter Cup Brownies

What starts as a seemingly ordinary brownie gets sprinkled with chocolate chips and peanut butter cup candies, baked until they just start to melt and puddle, and then topped with a double thick layer of crispy chocolate and peanut butter paradise. It’s like brownie meets rice krispie treat meets peanut butter cup… meets my mouth.

This recipe comes from my friend Averie’s delightful new cookbook, called Peanut Butter Comfort. An entire book about peanut butter? I’m sold. But of course I flipped right to the peanut butter and chocolate chapter, as that is where my true heart lies. (Also, if the idea of a peanut butter cookbook makes you giddy like a schoolgirl, you don’t want to miss tomorrow’s post!)

And remember, even though it seems like a 13-by-9-inch pan makes more than enough, wrap up a few bars and tuck them in a dark corner of the fridge, maybe behind the broccoli or the who-knows-how-old-it-is jar of whatnot where the other members of your household won’t think to look. Trust me. Your future self will thank me later.

Rice Krispie & Peanut Butter Cup Brownies

Yield: 18 to 24 brownies

Cook Time: 45 minutes

Total Time: 3 hours


For Brownie Base:

  • 3/4 cup (1 1/2 sticks) unsalted butter
  • 1 3/4 cups semisweet chocolate chips, divided
  • 1 1/2 cups granulated sugar
  • 1/2 cup light brown sugar, packed
  • 1/2 teaspoon instant espresso powder or 2 tablespoons brewed coffee (optional)
  • 1 1/2 teaspoons vanilla extract
  • 3 large eggs
  • 1 cup all-purpose flour
  • 8 full-sized peanut butter cups, chopped, or 1 cup mini peanut butter cups

For Crispie Topping:

  • 1 1/2 cups semisweet chocolate chips
  • 1 1/2 cups creamy peanut butter
  • 1 tablespoon butter
  • 1 1/2 cups crisp rice cereal


  1. Preheat oven to 350 degrees F. Line a 9-by-13-inch baking pan with aluminum foil; spray lightly with cooking spray.
  2. Combine butter and 3/4 cup chocolate chips in a large microwave safe bowl. Heat on high power for 60 to 90 seconds, stirring every 10 to 15 seconds to prevent scorching. When chocolate is melted and mixture is smooth, stir in sugar and brown sugar. Batter may seem grainy, that's ok.
  3. Add the coffee or espresso powder and vanilla extract and stir until smooth.
  4. Whisk in eggs until incorporated. Sprinkle the flour over top and fold until just combined. Stir in 1/2 cup chocolate chips then pour batter into prepared pan.
  5. Bake for about 25 minutes or until brownies are mostly done. Remove from oven and sprinkle chopped peanut butter cups and remaining 1/2 cup chocolate chips over top, then return to oven and bake for 3 to 4 minutes more. Transfer pan to wire rack to cool.
  6. Meanwhile, to prepare topping, combine 1 1/2 cups chocolate chips, peanut butter, and butter in a large microwave safe bowl. Heat on high power for 1 minute, stirring every 10 to 15 seconds, until melted and smooth. Add rice cereal and toss to coat. Spread cereal mixture in a smooth layer on top of brownies, then cover and refrigerate for at least 90 minutes or overnight, or until topping is cooled and set before slicing and serving. Brownies will keep, refrigerated in an airtight container, for up to 1 week.

    Lindsay they are beautiful! They make me want to re-make this recipe! As you said, even though a 9×13 pan seems like plenty, it’s always good to stash a few :) I am so glad to hear they were a hit and I am convinced that no matter the weather, PB + chocolate are always a win.

    Thank you for trying this recipe from my cookbook and for the wonderful post!

    And that tree trunk board…you find the BEST props! I want it! :)

      Found it at World Market! Word of warning: it smells like bacon (go figure).

      Not sure if they’re the same but I would guess those little PB cups are from Trader Joe’s…if not, they’re VERY close.  I recommend if you have a TJs near you. Tasty but not overly sweet.

    The amount of chocolate chips in the brownie part doesn’t add up. Or else I am just missing it (which is possible, it happens all the time). I think you have a remaining 3/4 cup for the melting on top of the brownie part. No?


    • Posted On August 13, 2013 at 12:32 pm

      You’re right, it’s 1/4 cup off, should be 1 3/4 cup total. Fixed in recipe! :)

    Loving your styling, Averie’s recipe and your first rule of entertaining, “… always stash some for yourself.” I have Averie’s PB cookbook and need to make these soon! Wonderful adaptation and post, Lindsay!

    I think this might just be the perfect dessert for my upcoming cocktail party on Sunday afternoon. And… if I pair it with grapefruit juice can I call it breakfast? It’s got eggs, cereal, coffee…..

    I haven’t been able to look at your site in weeks as my husband and I are currently eating Paleo, and I just caved and had to see what you’re baking and feel like I cheated on my diet just reading this! Delicious.

    These sound like a mixture of Crunch bars and Reese’s pb cups…and that’s all good!

    I couldnt resist making these last night. Unfortunately, I miss judged the cooling time, so we couldnt have them with the pre-season football goodies. But TODAY… these were freaking awesome!! I brought half of them to work and my desk has been mobbed all day!
    Thank goodness the recipe gives you lots of brownies, or my life may have been in danger!
    Thank you for sharing the LOVE & OLIVE OIL! (see what I did there?)

    Posted On August 20, 2013 at 10:04 am

    These look aaaamazing! I need them in my life right now! I’d need to make them when I have people round though, otherwise I’d definitely eat all of them to myself!

    Posted On September 5, 2013 at 12:14 pm

    Will these last awhile? I have free time today to make these, but I will not need them until two days from now. Whattya think? Thank you!!


    • Posted On September 5, 2013 at 12:45 pm

      Covered and refrigerated, yes, I think they’d be fine for 2 days, although the crispies might not be quite as crispy as the first day. But I think the bigger problem is can you not devour them while they sit there for 2 days? haha. :) Good luck!

    What a wonderful recipe! My grandsons are going to love this and they are big peanut butter lovers.
    My hubby doesn’t like PB so that means the ones I put aside I won’t have to hid…I get to eat them all!!!! Thank you.

    I just found peanut butter filled oreos at CVS.  I might chop some up and add them to that middle layer.  Do you think that would be CPB overkill?  Naw!

    Posted On February 13, 2014 at 11:19 am

    They are in the oven now. making for my honey  for Valentines day. Hopefully i won’t eat  all the peanut butter cups before they goon the brownies

    Posted On February 16, 2014 at 3:23 pm

    It says total cook time 45 min but then in instructions says to cook for 25, add chips and PB cups then cook 3-4 min more? Mine are still liquid after 30 min? Is this wrong? I’ve never done brownies before… Please help!!


  51. 51
    Posted On February 17, 2014 at 9:47 am

    I cooked mine the 25 minutes then 4 minutes more. once they are cooled, they are okay. they look like the ones in the picture and everyone who tastes them says they are good,you just eat them cooled,not warm. so i guess they are supposed to be gooey on the bottom. but to me 25 minutes does seem to be too little time.

    This recipe looks so good, I shared the link on my blog today in my list of Fabulous Finds, even before I have made it myself. The ingredients are lined up on the counter now, and I will be mixing these up in just a bit! Pinned as well, and I’m following you on Facebook now. I’m glad I happened upon this recipe!
