The best magic cookie bars

You know what a magic cookie bar is, right? You know, the super easy dessert that has seven magical layers that turn into a delectable sweet treat?

These monster magic cookie bars are a delicious twist on a classic 7-layer dessert bar.

I have this habit of combining desserts when I can’t choose between two. In this case, we’re talking monster cookie bars and magical dessert bars, also known as dolly bars, seven-layer bars and magic bars.

Monster cookies are loaded with peanut butter, M&Ms, pretzels, and nuts and magic bars have coconut, graham crackers, chocolate and sweetened condensed milk. So, I thought, why not combine them and create a whole new dessert with the best of both worlds?

I played around with the idea and took from each what I think are the best parts. I left out the coconut and graham crackers from the magic bars and added my favorite monster bar ingredients and came up with these seven wonderful layers:

  1. Nutter Butter cookie crust
  2. Chopped pecans
  3. Chocolate chips
  4. Peanut butter chips
  5. Chopped pretzels
  6. M&Ms
  7. Sweetened condensed milk

They’re Easy to Make – Just Assemble and Bake!

Once you have your ingredients these seven-layer bars are so easy to make. I love that you don’t have to pre bake the crust before you assemble them.

  • Make the crust: I like to use my food processor to crush the Nutter Butters. Then just mix the crumbs with some melted butter and press the mixture into the bottom of the baking dish lined with parchment.
  • Add all the layers: Sprinkle the chopped nuts over the top of the crust followed by the chocolate chips, peanut butter, chips, pretzels and M&Ms. Pour the sweetened condensed milk evenly over the top.
  • Bake: Pop the bars in the oven and bake them for 25 minutes at 350 degrees. Cool the bars before slicing and serving.

I am in love with this monster cookie bar version, but you can easily swap ingredients to create your own customized seven-layer cookie bars! This recipe is so flexible so don’t be afraid to experiment.

  • I love Nutter Butter cookies, but any peanut butter sandwich cookie will work for the crust. Or, you can use crushed graham crackers, Oreos, or vanilla or chocolate wafer cookies.
  • Use almonds, peanuts or walnuts instead of pecans. Or do a combo!
  • Swap out peanut butter chips for butterscotch or white chocolate chips if you want to change up the flavors.
  • Instead of M&Ms try some chopped peanut butter cups.

Can you freeze magic bars?

Yes, they freeze great! Just bake them as instructed and let them fully cool. Wrap them tightly and they will keep in the freezer for several months. To thaw, you can pop them in the refrigerator or leave them out at room temperature.

These monster cookie bars are so rich and decadent. A little goes a long way so you can get a lot of mileage out of one pan making them perfect for potlucks, BBQs and other parties when you need to feed a crowd. Or, keep them all to yourself – I won’t tell!

  1. Oh, my goodness! Those look so yummy! I’m hosting a linky party “One Creative Weekend” at I’d love for you to visit and link up this idea and/or anything else you’d like to share.

  2. Ahhh yes, I can relate!!! Being with children 24/7 is enough to drive me straight to the pantry! These look incredible. Can’t wait to try them. Hey, I live close enough… maybe you could just drop some off at my house šŸ˜‰

  3. Dorothy,
    Tell me about the attitude! One would think the kids were on vacation from LIFE too not just school. lol I can’t wait for August 17th and NO MORE LIP!
    On a happier note, these look like just the thing to keep me calm too. Can’t wait to try them. Thanks so much for linking up to Creative Thursday this week. I can’t wait to see what you link up next. Have a great weekend.



  5. Funny – our daughters sound like the same person:) love your bars !! Wait til Stella sees them, I may be making a trip to the store soon

  6. I don’t know if it’s worse or not (because I was a kid while my mom probably thought the same thing you are thinking now) but forreals, I think it’s *kinda* sad that my family acts the same way as an excited summer-vacay seven year old. I mean, they’re grown adults and they STILL leave trash and dishes and shoes EVERYWHERE, and don’t EVEN get me started on the DVD collection when they decide it’s viewing time. Gross. It was enough to make me go into a meltdown, and then you so graciously brought me some bars and alas, all was better in the world. These were awesome. The Nutter Butter crust was insane, and my favorite part was actually the nuts. I loved their unexpected crunch toward the bottom and dug them out with my teeth first šŸ™‚ so good! Sweetened condensed milk, you are my friend forever.
