Chocolate Peanut Butter Krispie Bars

My friend, Deb, shared these totally irresistible bars on her blog, Diva Entertains. From the instant I read the recipe, I knew I’d have to make her Chocolate Peanut Butter for the 3 peanut butter chocolate lovers in the household. When home from college breaks many eons ago, I remember rushing into the kitchen, even before unpacking, to make either pumpkin bread or peanut butter Rice Krispie Treats.

I wonder what nutrients my body was missing for me to have such intense cravings?? Maybe my diet of popcorn and Diet Cokes wasn’t nutritionally sound??? I adore the classic Scotcheroos made with pb, corn syrup,  Rice Krispies with a topping of melted chocolate chips (my mom’s version did not contain butterscotch chips), so I was dying to try these babies as much for myself as two of my children.

Tips for Making Peanut Butter Rice Krispie Treats

Well, these did not disappoint. You Reeses’ fans MUST try these. A candy thermometer is necessary to make the base…but this cook’s tool can easily be found at the supermarket. Rice Krispies are mixed with a hot sugar syrup to form the base, then a mixture of peanut butter and milk chocolate form the middle layer, and a creamy topping of melted semi-sweet chocolate completes this trifecta of deliciousness.

When Tom was over for one of our Sunday night family dinners, I told him he could take some of these home. Katie’s look of exasperation said it all…she did not want her brother to abscond with HER bars. So you might want to break out the 9 x 13 and make a double batch. They are totally delectable and capable of starting a family feud…though my two oldest agreed to split the remainder of these bars 50-50. Whew.

Tip of the Day: I have shared this one before, but worth another mention…especially after numerous requests.  To make perfect, clean cut squares, first chill your bars. Then take a large knife (I use my santoku) and run it under very hot water, swipe it dry, cut, wipe, reheat and repeat.

  1. After a maiden voyage into the kitchen to try your PB Chocolate Rice Krispies recipe (via your friend), I may be catapulted into a Rice Krispies baking phase.I can see how a rainbow of food combos and textures could be used.

    Your choice of corn syrup somehow seems like it might be easier than marshmallows. I’ll just have to give it a college-try and find out!

  2. Another recipe before my peanut butter loving son gets here on Thursday. Thanks again.

  3. Looks like another great treat! You need to do a tutorial on how to cut desserts so perfectly:@)

    • that’s so funny, I was thinking the exact same thing! the very first thing I noticed was how completely perfectly those squares are sliced!! not to mention they look insanely delicious.

  4. They look simply amazing 😀 I have to try them! 😀

    Have a great day!

  5. Lizzy, I would fight for these yummy bars too!

  6. Another wonderful recipe my kids would LOVE! Thanks for sharing 🙂

  7. Lizzy,
    Your bars look gorgeous! I have one finicky sister that won’t eat peanut butter, so I may swap with Scoff. Hopefully they will be as delicious as yours.

  8. These look amazing, but I don’t know if I can wait between chilling times to enjoy! I have a tendency to cheat before treats are ready.

  9. I´ve never made rice krispy treats because they usually have marshmallows and I can´t get them here. But this is the right recipe, no marshmallows but a nice dose of pb! Love it. And I should make homemade marshmallows sometime.

  10. I think I need to come over there so that you can teach me how to cut my bars or cheesecake neatly 😀 Those moreish and delicious bars look terrific !

  11. I am drooling over here! Only a few more days until Lent is over!

  12. Oh yeah. I can already tell that there’s no way I’d be able to make just a normal batch of these. Doubling is a must, though it wouldn’t be siblings fighting over them; we’d have father and daughter duking it out. 🙂 They look delicious (even to me).

  13. EEK! Those look DEEELISHHHH! Perfection in a bar.

  14. ahhhhhh amazinggg! Peanut butter=love

  18. It is treats like this that I absolutely swoon over. I never had peanut butter treats growing up. Now they are a favorite.

  20. You can never go wrong with chocolate and peanut butter together – always a winner!

  21. They look great and wonderful recipe, my son would love to have these!

  23. These look delicious! What a great treat.

  24. I am a huge Reeses fan so I already know that these wouldn’t last long in my hands!

  25. Talk about a sweet delight, wow these look amazing. Also I’m amazed at how you cut them so……. straight, I have such a terrible eye when it comes to cutting so this is very impressive along with being so delicious looking!

  26. OMG, Liz! I am in chocolate peanut butter heaven here and I would smack you if you told someone they could just take them away from me. In fact, I might need some kind of intervention with these things around!

  27. No one bakes bars like you Liz!

  28. Oooh, I like that burlap background! I need some of that. 🙂 And I really like the bars – I love peanut butter, and never had it in rice krispie bars. Terrific idea – thanks.

  29. Pretty pics. Wow, if I had a nickel for all the Diet Cokes I drank in my twenties, I would not have to be working today! 🙂

  30. These certainly do look delectable. I love caramel and chocolate and when they get layered together, it is heaven. Diet coke is my poison too!

  31. Chocolate and peanut butter were made to each other…These bars are so beautiful and look so scrumptious that is literally to die for!!! Happy Easter, Liz!

    Sigh… 🙁

  38. My kids would love those, since my eldest has just discovered peanut butter recently. Well, yes. We’re behind here in France, lol.

  39. Thanks so much for featuring these! It is one of our top 10 desserts of all time:)

  40. The peanut butter and chocolate combination is not common in Australia and for a yank like me, every once in a while I need to get my “fix.” I think these bars would suit very nicely indeed.

  41. Hi Lizzy! Did you use a ruler to measure and cut out the squares? 😀

    So neatly cut and they look so yummy. Mouth watering!

  42. Mmm these bars look soo yummy. I need to make these for the family. Thanks for sharing.

  49. —Delish presentation.

    Fabulous sins! Xx Wwwwow

  50. Oh my goodness, those bars look completely irresistible. What do I need to do to get my hands on one of those?!!

  51. I think I’ll be using your clean cutting tip for making these bars! what a perfect combo! how could anyone resist?

  52. Goodie…goodie…goodie… these rice cereal bars. Yours look so perfect.
    Happy Belated Easter Day. ((hugs))

  53. I don’t get it? Where is the recipe for the caramel layer and where does caramel go in the recipe?
    You and your friend at Hugs and Cookies have Caramel in the title but it isn’t in the recipe. I am about to make them but not sure how to proceed.
    Hope u see this and can clear it up.

    • Hi, Karen,
      There is no caramel in these (not in my title, either!). I think Danielle just made an error in her title and wrote Caramel instead of Chocolate. Sorry for the confusion!!! I hope you still enjoy the recipe.

  54. These are totally irresistible! Such a perfect treat! My kids couldn’t stop eating!
