These are so dangerously simple. It’s a soft and gooey brownie layer topped with a supremely chewy peanut butter Rice Krispy treat layer for an ultra chocolaty, ultra peanut buttery, ultra munchable brownie delight.

Hoe to Make These Rice Krispie Brownies

To make, just prepare a batch of your favorite brownies – I used a box of Ghirardelli brownie mix – they are so wonderfully rich!

And as soon as they come out of the oven, you can start your peanut butter Rice Krispy treats! Combine sugar and corn syrup in a heavy bottomed sauce pan (Sir Mix-a-Lot style) over high heat.

When it comes to a boil, remove it from the heat…

And immediately press on top of the brownies.

Oh! Btw, I hardly ever, ever line my baking dishes with foil (I’m normally way to lazy to be bothered..), but you’ll probably want to for these. It’s really the only way to get them out so you can cut into these babies! :)

That’s it!! Can you believe how quick and easy these went together? Definitely dangerous for such a delicious delight.

Since I used an 8×8 brownie mix (instead of a 9×13 brownie mix) I had a little of the peanut butter krispy treats left over. Aww. What ever am I going to do?

I’m still wringing my hands with worry over that one. Snort.

    Wow! Chocolate, peanut butter, rice krispies and brownies??? Get outta here! I’m bookmarking this now! Not sure how I haven’t seen your food blog before now. Great recipes, great photography, great writing!

    I made these last night & they were so good. I actually made the brownies from scratch though & it was incredibly rich, which was good because it stops me from eating the entire batch of them. lol.

    I’m planning on making your Chocolate Chip Cookie Dough Cupcakes for Thanksgiving with the future Brother in law & his wife. :)

    I linked you to my page, I hope you don’t mind. :] You’ve inspired me so much, you can tell just by looking at my blog. LOL!

    Thank you AMANDA! ♥

    Those look tasty. My favorite bit of the post though? Where you snorted! I love that you’re so down to earth and sassy. Keeps me coming back for more. I am so going to make these for Thanksgiving for the office.

  4. Wren Manners

    I made these treats for our tailgate at Auburn Univeristy. They were so great – however – we left our tent set up during the game and when we returned – not only was my good glass casserole dish gone but so were all of my 100 brownie – krispy treats!!!! They must have been REALLY REALLY good! I didnt even get one!

  5. Yanely

    Just wanted to tell you that I made your Cookies & Cream Fudge Brownies and they were a hit at work!!! I’ve had to make them 2 weeks in a row cause people can’t get enough of them!!! They have even inspired a Dessert Day @ work….Thanks for making me awesome!!!

  6. Debi

  7. Sandy

    These look amazing! I can’t wait to make them! On another note, you have created a monster! I’ve always been a snob about candles – you know, had to have the expensive ones – but now, thanks to you, I pick up a candle or two every time I go to Walmart and I’m loving them! Right now I have a hazelnut creme burning in my kitchen – yum! – and I love the mulling cider candle. Thanks!

  8. Maryrose

    Ok, girlfriend. I made those Chocolate Chip Cookie Dough cupcakes and all of my friends and family think I am a rockstar (I had to credit you, don’t worry!). What will they think after I make these??!! You’re the BEST!!!

  10. Amy at The Scene From Me

  12. Ashley

    my family has made rice krispies sort of like these for years! we just put melted chocolate and butterscotch chips on top instead of brownies on bottom. but you can bet i will be trying these babies!

  13. Shannon

    I see all of these fabulously rich desserts you post on here, and I know you recently lost weight. Are you just not keeping these in the house, or are you one of those people with incredible will power. What’s the deal? :)

  14. Elysia

    Normally I am so on board with you. I love PB, rice crispy treats and brownies (not necessarily in that order :)) But these don’t look or sound good. I can’t imagine these mixtures of texture.

  15. Suzan

    OMGosh these look sooooooooo yummie!!!! And a good way to gain weight too! (lucky me I have to gain some LOL!)

    Thanks for sharing :)

    Love from Holland

  16. Becky

    I will have to make these for Thanksgiving. They look yummy-o-shish. Could you send me one to sample through the lines ? LOL. I just want to know your secret for staying so slim and making all these goodies. I’d be chowing down on them and finishing them off in a day. Thanks for sharing. You always have the best photos of your yummies. They make me soo hungry. I’ll have to go eat a mini hershey bar dipped in peanut butter. :D Love your website. ((Hugs)), Becky

  17. KarrieLyne

    So…I LOVE chocolate and peanut butter together!! I’m totally making these tonight to take to my stitch and bitch tomorrow. :D

    I was wondering though, you have a jar of chocolate topping in your photo of ingredients….but it’s not in your recipe. What do you use that for? Topping? :D

  18. Nicolle

    Okay I just need some clarification before I indulge my husband and I with this wonderful treat….

    Do you cook the brownies first, then layer it with the rice krispy treats? Or bake them together?

    Thanks for sharing such delicious food and treats! :)

  19. Debi

    OH MY!!!!! Those look sooo yummy. I just (yesterday) made a box of those Gharadelli brownies….my goodness are they wonderful… can’t wait to try them with the peanut butter rice krispies on top….. Thanks sooooooooooooooo much Amanda for this great – fun – fun – fun website….I love it…

  20. wenders

    That’s so funny, I just HAPPEN to buy the same exact brownie mix couple days ago. This sounds so yummy, will need to give it a try!

  21. Sharon

    Okay. Enough. I love your weightloss story. Then you proceed to introduce all of these AWESOME recipes! How can you do both and be successful? How do you stay so skinny?
    I would really love to know.

  22. Pati L

    I’ve made a similar recipe years ago. I think it had chocolate on top also, from melted choc. chips or something. I noticed the the jar of Smuckers ice cream topping in your ingredients pic, was that used in the brownies or did you put it on top of the bars after the last pic?! : )

  23. Crafty Cammie

    Oh my Amanda these look so amazing! I just love all of your food posts and your pictures that go with them. I have made several of your recipes for my family of six and we have loved them all. I am running to the store right now to get the “goods” to make these for an after school treat. Thanks for everything you do!!

  24. Bonnie

    Just thought I would give you an another way to make the peanut butter rice krispies…just put the sugar, karo, and peanut butter in a bowl and microwave it for 1 minute and 30 seconds to 2 minutes. Then stir in the rice krispies. These are the only kind of rice krispies I make at my house!


    Dear Ms. Amanda,
    Please stop posting food! I have to workout for 1 hour after just looking at your post!
    P.S. Not really, just kidding, keep on posting them! Love it!

  26. teresa

    Love your SPIRIT sweet girl!

  27. Southern Gal

    My whole family will love these. Rice Krispie Treats are my son’s favorite and they all love peanut butter and brownies. Good combination!

  28. Cary

    Amanda, what I really want to know is how you stay soooooooo thin?
    You are always posting a DELICIOUS recipe!! Can’t wait to try these!

    For years I have been making the peanut butter krispies, with melted chocolate and butterscoth chip drizzled all over the top, love them. I will definitely be giving this a go :)

  32. Jody

    These look so good! Our HS football team is in playoffs. My daughter is on the dance team and we always put together goodie bags every week. It’s too late for this week, but I am definitely making these for next week!

  33. Elisa

  36. Jessica @ How Sweet

    I make some brownies like these – the better-than-crack brownies. They are to die for. In my opinion, anything with chocolate and peanut butter is a lethal combination.

  37. Estela @ Weekly Bite

    Wow! Amanda these look amazing! And they include all my favorite things!!

    Those are my favorite box brownies! And who doesn’t love rice krisy treats!
