Weekends always go by so fast! Even though it seems like we don’t do a lot on the weekends, whenever anyone asks me, “so what did you do this weekend?” I always have a hard time answering that. I don’t know why but I’m always searching my brain for what we did. Sometimes, I wish I could say, “we went skydiving” or “we took a weekend trip to Paris,” instead of, “oh you know, Costco, errands, the usual.” Now that I’m thinking about it, one thing I could say that happened this weekend was I caught a 24-hour stomach bug and that really sucked. I think I would rather have the flu than the stomach bug, although, I’m definitely not wishing for the flu, I’m just saying in comparison to the stomach bug, the flu just sounds less painful, if you know what I mean.

Oh! Jason and I watched Zero Dark Thirty on Saturday. We wanted to keep up with the terrorist theme (Homeland, Zero Dark Thirty), apparently. It was really good. My heart was beating out of my chest and I couldn’t breathe half the time because of the suspense. Even though we all know what happened at the end, just finding out all the details and watching the operation unfold was just intense. Have you seen Zero Dark Thirty yet? It’s been on our list for a long time and we finally got around to it! I highly recommend it.

So these layer bars. I had the hardest time coming up with the name for them. My aunt, whom I got the recipe from (I love that she’s just full of delicious recipes!), didn’t have a name for them. She made them over Christmas and she didn’t really have directions, either, for this. She just gave me a list of ingredients. Thankfully, I’ve done my fair share of baking and layer bars so I was able to figure it out. Although, I did fail two times before successfully making these work. It’s all in the pan size, people!

You’re going to love these layer bars. They’re EASY to make and so addicting. They have a peanut butter crust, a gooey marshmallow filling, and topped with butterscotch rice krispies. Uh, hello! Amazing!

Layers of flavor! Butterscotch, marshmallow, & peanut butter..perfection!

Servings: 1 11x7-inch baking dish
  • 1: 14.5 package of pre-made peanut butter cookie dough
  • 1: 10 ounce bag of miniature marshmallows
  • 1: 11 ounce bag of butterscotch chips
  • 4 tablespoon unsalted butter
  • 2/3 cup corn syrup
  • 1 tablespoon vanilla extract
  • 5 cups rice cereal
  1. Preheat oven to whatever temperature the cookie dough package says.
  2. Line a 11x7 baking dish with parchment paper with 2-inch overhangs on either side.
  3. Press the cookie dough into the bottom of the baking dish in an even layer.
  4. Bake for however long the cookie dough package says.
  5. When the cookie layer is done baking, immediately pour bag of marshmallows on top of the cookie layer then put back in the oven for 5-7 minutes, until the marshmallows soften and become slightly melted (this could be less than 5-7 minutes). Remove from oven and set aside.
  6. In the meantime, in a large, non-stick pot over medium high heat, melt butterscotch chips, butter, corn syrup, and vanilla extract together. Once the butterscotch chips have all melted and the mixture is smooth, turn off the heat and stir in the rice cereal. Stir until rice cereal is completely and evenly coated with the butterscotch mixture.
  7. Place the butterscotch rice krispy layer evenly on top of the marshmallow layer and gently press down to flatten. You'll probably have to do this in parts as the rice krispy layer doesn't "spread."
  8. Let cool for at least 6 hours or overnight.
  9. Slice into squares and serve.

    Girl!!! These look insane. I don’t think I could be trusted with a pan of these in front of me- all my favorite flavors in one!

  18. 02/10/2014 at 12:27 pm

    They turned out so good!!! Love the shots you got of them.

  19. 02/10/2014 at 12:46 pm

    We started Zero Dark Thirty about a year ago, and I had to turn it off after 10 minutes because I just couldn’t take the torture scene in the beginning. Probably didn’t help that we were eating lunch. But thanks for the reminder because I’ve been meaning to give it another try. These bars look amazing! Yum!

  20. 02/10/2014 at 1:20 pm

    Wow! These bars have my name all over them!

  21. 02/10/2014 at 1:43 pm

    I’ll take the whole pan please!

    Oh my, Oh my! I want these right now! This look amazingly naughty!

  23. 02/10/2014 at 2:03 pm

    Ooh you know the way straight to my heart. These look DIVINE!

  24. 02/10/2014 at 2:19 pm

    I have seen Zero Dark Thirty and it was very good, we need to start on this past season of Homeland soon! These treats looks so yummy!

  25. I’m sure Zero Dark Thirty isn’t as good as these bars! Yum!

    I made these this morning and they are delish! Thanks!

  28. 02/10/2014 at 5:10 pm

    These krispy bars look so delicious! How would you spice these up for Valentine’s Day?

  29. 02/10/2014 at 5:35 pm

    These look totally irresistible and delicious! Love the distinct layers Julie!

    I plan to make these bars real soon and I am going to sprinkle some sea salt over them. Sound good?

    • 02/11/2014 at 7:01 pm

      Hmm that’d be interesting. I’d say go for it but maybe do it on one first and taste it before you do the entire pan.

  32. 02/10/2014 at 6:11 pm

    Bless you for making these bars. Now if you could mail them all to me that would be most appreciated. ;)

  33. 02/10/2014 at 10:19 pm

    OMG – Fluffernutters! I grew up on the East Coast and ate a Fluffernutter sandwich almost everyday for most of my childhood. I’ve noticed that people on the West Coast don’t really seem to know what a Fluffernutter is. This sounds like a fun recipe Julie!

  34. 02/10/2014 at 11:38 pm

    Zero Dark Thirty was so intense!! I couldn’t handle it. Let me eat one and calm down a bit.

  35. 02/10/2014 at 11:46 pm

    These look amazing Julie! I only recently heard about fluffernutter, and I’ve been anxious to make something (anything!), so this looks likes the perfect thing. And, the stomach bug? No fun!!! I had the same thing myself and it’s awful! So glad you’re feeling better! Cheers!

    These sound so sinfully good., thanks for posting the recipe.

    Question, who makes the package of pre-made peanut butter cookie dough?

    • 02/11/2014 at 7:01 pm

      Hi Dieselle, I used one from Pillsbury.

      • Kayla
        02/11/2014 at 8:39 pm

        And you bake it according to package directions and then the extra 5-7 minutes with the marshmallows, or the baking time should equal that on the package including the 5-7 minutes when you put it back in to cook the marshmallows?

      • 02/12/2014 at 11:17 am

        Yes, bake it according to package directions then the extra 5-7 minutes with the marshmallows to melt a little.

  37. 02/11/2014 at 12:12 am

    I didn’t think it was possible to best a fluffernutter. Clearly, I was way wrong. Yum!!!

  38. 02/11/2014 at 12:32 am

    Wow, what the fluffernutter is going on here, amazing!

  39. 02/11/2014 at 3:12 am

    Julie, these look completely addictive! I bet the 3 tries made these bars well worth the effort!

  40. 02/11/2014 at 5:20 pm

    These bars are fluffy delights! They look so delicious.

  41. 02/11/2014 at 7:57 pm

    These look dangerously delicious, Julie! So fluuuuuuffy!

  42. 02/11/2014 at 8:25 pm

    oh how delicious! They look wonderful :-) My wife likes to change up the rice krispie treats all the time, trying different things!

  43. 02/12/2014 at 12:33 pm

    These sound completely amazing! Every.single.aspect. I see a big pan of these in our near future!!

  44. 02/12/2014 at 4:09 pm

    Oh my, this looks soo good! Got yourself a new follower on bloglovin’ :)

  45. 02/14/2014 at 9:04 pm

    These look like the best rice krispy treats ever!

    Due to Celiac Disease, I have to eat gluten free vs. following a trendy diet. I’m thinking of using the Pillsbury gluten free chocolate chip dough that is pre made and then using the rest of the ingredients and see what happens!!!! I can’t imagine it not working!!!

    • 02/18/2014 at 9:55 pm

      Sounds delish! Hope it works out for you!

  47. 02/19/2014 at 3:13 pm

    Oh my gosh, this sounds amazing! Just pinned it to make very soon.

  48. 03/01/2014 at 5:45 am

    I wonder- how do you think it would turn out using PB chips instead of butterscotch with the peanut butter cookie crust, or sugar cookie crust with the butterscotch chips?? The do look yummy!!!

    • 03/01/2014 at 8:57 am

      Sure, that sounds great!

    I asked my daughter if she wanted cake for her 4th birthday or butterscotch fluffernutter krispy treats and she got wide-eyed and excited to respond butterscotch treats!! We just made them and they are awesome!!
    Thanks for the great idea!

    • 03/05/2014 at 8:26 am

      I’m so glad to have made your daughter’s 4th birthday! Yay! :)

    My grocery store didn’t carry the peanut butter cookie dough so I had to change the recipe slightly. I used chocolate chip dough and peanut butter chips, and it was amazing!!! Can’t wait to try it your way.

      That still sounds lovely!
