Gooey fantastic!  Tip:  Butter your mixing spoon, it’s much easier to stir.  Don’t forget to mix ingredients quickly before mixture starts to set up.

Let the chocolate peanut butter layer set up then cut into squares and serve!

Tips For Making The Best Krispie Treats

  • Use fresh marshmallows and cereal.  If your marshmallows are old and stale, your treats won’t be great.  Brand new bag of marshmallows and cereal recommended.
  • Careful when melting your butter, if you brown it, krispie treats tend to be dry.
  • By adding slightly more marshmallows, you’ll get a gooey-er krispie treat.
  • Add pure vanilla extract or even vanilla bean to your melted marshmallows.  So good!
  • Butter your pan generously before adding krispie treats to set.
  • Butter your hands before pressing krispie treats into pan.  Lifesaver.
  • I even butter or spray my mixing spoon with cooking spray to stir mixture.  Helps big time.
  • Add your favorite chocolates to the mix.  Chocolate chips, M&M’s….sprinkles.  Get creative.  Lots of fun options.

  1. I used Nutella instead of peanut butter, and a chopped up milk chocolate hazelnut candy bar in place of the Reeses cups and it turned out great! Perfect for Nutella Day 2001!

    Oh. My. Lanta. These were to die for! Haha being a teenager, i have a pretty fast metabolism; however, I’m also an only child and knew if i didn’t give these away to neighbors i would devour them all:) The family I gave them to fell in love the minute they saw them. I’m a definate chocoholic, so i used cocoa krispies:) Thanks so much for the recipe!

  3. Ok..I just put these in the fridge! It was super easy. I made them to take to my friends picnic this evening. Don’t worry, they won’t melt in this 95 degree weather…all food will be inside! Did I mention that I took a rubber spatula and scraped the remaining peanut butter/meltedey Reese’s cup mixture and licked the spatula clean! Can’t help it…my two favorite things..peanut butter and Reese’s cups! Great recipe!

    I made these for a bbq with friends and the ENTIRE pan was gone. Seriously- I didn’t think rice krispy treats could get much better but these are AMAZING!! Love your blog! I made the Ice Cream Sundae cake last BBQ that was so good too! Thanks for making me look like a pro! 🙂

  5. These are making me drool! Just shared then on FB and ready to do the same on Twitter. YUM!! I am also on batch #3 of the ice cream cookies. Wow! What a fun site 🙂

  6. Oh my goodness! This looks utterly fantastic! I am definately going to make this. I love Reese’s peanutbutter cups! My kids and hubby will gobble these up for sure! I am new to your blog…I found you by way of Summer Harm’s blog. I clicked on her new post for Smithfield and found you there as well. I am so happy I found your blog, and congrats on the Smithfield posting as well!

    1. Great to have you Bonnie! I am excited to meet the other Smithfield bloggers, LOVE Summer’s picture she posted, so cute!!

      Thanks for stopping in 🙂

  7. These look delicious, I will definitely be trying them. I have to add that I absolutely love your blog – the way you tell your baking stories in pictures (with amazing photography) is just awesome. Kudos to you! (ooh, maybe you can make something using Kudos!)


  8. Oh these are some family favorites you’ve got in this recipe! How do you dream these things up? I’ll bet you are the ‘cool mom’ in the neighborhood since you serve up such yumminess.
    Just have to say that I love the way you took the pic of the marshmallows so it looked as if the Rice Krispie characters were enthusiastically looking at your bowl of white pillowy goodness. Nice touch – it made me smile. 🙂

    OH MY! Peanut Butter is one of my greatest weaknesses – I have to have these NOW! Thanks for another great recipe! Have a great week.

    I actually make these with the peanut butter mixed right in with the marshmallow and the chocolate over the top…the peanut butter makes them even gooier!

  11. These look AMAZING! This morning I was just getting ready to make some rice crispy treats … Now I really think I need to go get some reese’s cups first! Gorgeous photography! (wonder how many weight watchers points this is :))

  12. OMG yum! I think i might borrow this for my kid’s cooking class next month. I am doing healthy baking, but one unhealthy recipe so this might be it!

  13. Camille

    Dang, my boys are allergic to peanut butter. Looks like the hubby and I get them all to ourselves! Wait, that’s a bad thing 😉
