Monster Magic Cookie Bars

I once worked with an older gentleman who told me that when his wife wasn’t home and he was left alone to babysit the grandkids, he fed them his two signature “grandpa meals:”
1. Cake batter. Mixed up. Poured in a cup. And served.
2. Sweetened Condensed Milk. From the can. Everyone got their own.
I kid you not. This man actually exists.
I did not make him up.
He’s completely fantastic.
Probably needs a great dental plan– but fantastic, all the same.


And I’m with him on the sweetened condensed milk thing–
I could drink it from the can.
I wish I was kidding. Totally kidding.
Consequently, I’m in love with all magic cookie bar recipes.
And you already know of my love of Monster Cookies.
Enter: Monster Magic Cookie Bars.

PS- there’s no peanut butter, making them a little less “monster cookie-ish,” but I don’t think it would be hard to incorporate into the crust if you wanted to!

Monster Magic Cookie Bars


  • 9 full graham crackers
  • 4 tbsp. butter
  • 1 can sweetened condensed milk
  • approximately 3/4 c. oats
  • approximately 3/4 c. M&Ms
  • approximately 3/4 c. chocolate chips
  • - See more at:


  1. In a zip top bag, crush the graham crackers using a rolling pin.
  2. Once crushed, add the 4 tbsp. butter to the bag.
  3. Place in the microwave and heat up for about 30 seconds.
  4. Remove from microwave, let out the air and make sure the bag is sealed (maybe let it cool for a second or two!), and “mush” the butter and graham crackers together until fully incorporated.
  5. Press the graham cracker crumbs into a well-greased and parchment lined 9×13 baking dish.
  6. Evenly pour the sweetened condensed milk over the graham cracker layer.
  7. Sprinkle the oats, M&Ms, and chocolate chips evenly over the sweetened condensed milk and gently press in a little.
  8. Bake at 350º for 30 minutes or until browned and pulling away from the edges.
  9. Let cool and serve.

    I’m not a big fan of oats…is there anything else I can substitute them with to make bars like this?

    Thanks so much!

    • Something Swanky posted on April 17, 2012 at 10:42 am (#)

      Well– they’re just magic cookie bars but with adaptations to be more like monster cookies. So if you don’t like oats, you could just make a normal batch of magic cookie bars! Here’s the recipe I use:

    • Ikhlas posted on April 17, 2012 at 10:47 am (#)

      Aaah, I get it! Definitely loving the mini M&Ms on top, so I’ll probably make some variation of this…

      Thanks so much! :)

    I really could drink sweetened condensed milk from the can. I love it! And we love the traditional Magic Cookie Bars. These ones look so good … I’m definitely trying them!

    man that is one smart grandpa, so going to remember that for when I am the “cool” grandma, my future daughter in law will hate me!

    Your monster magic cookie bars look fantastic! I’ll be forced to hide them from my son (more for me!) after I make them. I shudder to think about the sugar-high those kids must’ve been on after a little time with grandpa, but I bet they were good for him!

    These look amazing. Do you mean 9 individual graham crackers? I may have to make them this week ;). Thanks!


    • Something Swanky posted on April 30, 2012 at 3:32 pm (#)

      I know, this is always kind of confusing to try and describe. So, 1 whole graham cracker = 2 squares. So 9 whole graham (rectangles) crackers…. did that make any sense?

    • Wanda posted on May 3, 2012 at 12:30 pm (#)

      Yes! Thank you!

  32. Kelli @ RTSM posted on May 8, 2012 at 9:10 am (#)

    That is a dangerous recipe! I love monster cookies and making them into magic cookie bars is genius. I think I might add in peanut butter chips too!

  33. TB209 posted on May 10, 2012 at 2:36 pm (#)

    For more peanut butter taste add peanut butter chips or reeses pieces…Must make these tonight! Thanks for the recipe!

  34. Paige posted on May 15, 2012 at 4:09 pm (#)

    If I am using graham cracker crumbs about how much would be equal to 9 graham crackers?

    For some peanut butter goodness added I bet you could just swap peanut butter chips for the chocolate chips! I’m so trying this later today! Sounds so easy!

  38. Lmullins posted on June 24, 2012 at 5:21 pm (#)

    Quick cooking oats or old fashion oats?

    • Something Swanky posted on June 25, 2012 at 8:43 pm (#)

      It won’t make a huge difference either way, but if you have the option, I’d go with old fashion oats!

  39. Designs By Jo-Anne Moreau Bougie posted on June 25, 2012 at 2:53 pm (#)

    Can you please tell me the measurements in cups if I used crushed graham crumbs I would need?? thank you :D

    • Something Swanky posted on June 25, 2012 at 8:27 pm (#)

      Hi hon! I sure hope you come back to check the comments! You’re a no-reply blogger which means that I can’t shoot you an email with my response in it!!!

      Hopefully you come back though :) I’m pretty sure this recipe calls for the equivalent of 1 1/2 cups of graham cracker crumbs :)

  40. Rachel @ Bakerita posted on June 27, 2012 at 1:35 am (#)

    These look delicious! Yummy. I love sweetened condensed milk a ton too…it’s so good! And can anything beat magic cookie bars? This looks like a fabulous take on them!!

  41. Beth Klemme posted on June 29, 2012 at 5:28 pm (#)

    These were soooo good. However they are not coming out of my pan as a bar. What did I do wrong I wonder? They are to gooey and are not solid, but I’m not complaining. They taste the same and are wonderful. I’m just eating them with a spoon. Scary.

    • Hannah S posted on July 5, 2012 at 2:02 pm (#)

      I had the same problem. I did not follow the directions and didn’t use parchment paper. But even still, they were quite thin and gooey in the middle yet crusty on the bottom. I am eating them with a spoon but not easy to serve up if I were to share it with guests. Did I not cook these long enough (I do have an atomic oven) or press down hard enough?

    • Something Swanky posted on July 6, 2012 at 9:47 pm (#)

      By “not follow the directions,” I’m assuming you mean the measurements? The only thing I can think of aside from not measuring everything out (although I’ve never found that to be TOTALLY necessary) is possibly your oven temperature (since everyone’s is a little different?) If you make these again, I would just use a little less sweetened condensed milk. And maybe bake the graham cracker crust for about 5 minutes before you add the rest of the toppings…

    • Hannah {Bonne Nouvelle} posted on July 9, 2012 at 3:53 pm (#)

      Okay, I’ll try that next time. The way I did not follow the directions was by using Pam spray instead of parchment paper. And yes, my oven is, to my shagrin, too hot. Thanks for the input.

    • sierrasarah posted on August 7, 2012 at 11:56 am (#)

      better to measure the crumbs… our 9 graham rectangles with butter would barely cover an 8×8 pan… had to crumb up more.

  42. Mama Jodi posted on July 5, 2012 at 11:09 am (#)

    Just pinned this. They look amazing.

  43. ReiLynnDesigns posted on July 6, 2012 at 3:16 pm (#)

    These look amazing! I’m thinking about giving up “real food” and just eating these, samoas dip and red velvet pancakes…. your recipes are so inspiring to get creative with our sweets! So much better than a store bought cookie…. Thank you!

  44. Amy posted on July 15, 2012 at 9:53 pm (#)

    These were so easy and yummy! I did make one big change though: instead of just graham crackers for the base I used half crushed pretzels and half grahams. I wanted something salty in the mix and this did the trick.

  45. crafty_momma_m posted on July 17, 2012 at 3:35 pm (#)

    these are AM.AZ.ING!!! seriously. i made them for a cookout and they were devoured! i had more than i should have and couldn’t stop thinking about them!
    the 2nd time i made them i added peanut butter chips along with the chocolate chips. hard to believe, they were even better! (if you like the pb) thank you so much.
    i’m going to exp a little in making them lighter. my friend who’s son is allergic to dairy said you can use bananas as a binder and i’m going to sub some bananas for some of the butter. if that works, i may just try subbing it altogether. i’ve never done it before, so i’m not sure how it’ll turn out.
    thank you so much for putting this AMAZING recipe in my head!!!

  51. chasidy mccarty posted on September 15, 2012 at 9:16 pm (#)

    I made these tonight, only thing I changed was I added 3/4 cup melted peanut butter to the graham cracker crust mixture, YUMMY! These are wonderful!

  52. Nichole 'Coley' posted on September 21, 2012 at 10:15 pm (#)

    Finally tried these tonight. This is what I learned: yeah don’t skip on the parchment paper… some of the M&M’s melted and the candy coating solidified to the pan in some spots. Sprinkle the oats on first, some of mine ended up on top, so they never really soaked in and cooked. I ended up using 1/2 cup oats, 1/2 cup crushed pretzels, 1/2 cup butterscotch chips, and about 3/4 cup M&M’s. Don’t make these if you aren’t ready to share, you will keep eating them….

    • Werries Family posted on October 10, 2012 at 11:33 am (#)

      Great idea on the crushed pretzels!!

  53. CaroleM posted on September 28, 2012 at 7:06 pm (#)

    Saw this on Pinterest on Wednesday, knew I had to make them for a bake sale this weekend, and made them on Thursday. Oh. My. I love this recipe and can tell you now it is going to be a “go to” recipe for me. I am so glad I did the Parchment paper as it made it so simple to pull out of the pan. I am having a hard time keeping them in the house long enough to bring to the bake sale tomorrow. Thank you!

  54. theglencoegirl posted on October 3, 2012 at 2:09 pm (#)

    i am making these as we speak–using reese PB pieces on top to make them “fall” looking!! can’t wait!!!

  55. Chell posted on October 17, 2012 at 8:48 am (#)

    My mom used to make magic cookie bars, but we called the Hello Dolly’s… But OMG this adaption looks even more amazing that Hello Dolly’s. Def going to have to make some soon!

  56. Erin posted on May 10, 2013 at 9:39 pm (#)

    how many ounces should the can of sweetened condensed milk be?

    • Ashton posted on June 12, 2013 at 11:56 pm (#)

      14.5 oz I think!

  57. Leah posted on May 13, 2013 at 8:20 pm (#)

    Do u know how many cups of crushed graham cracker 9 crackers makes? I’m gluten free and have already gluten free graham and would like to use it. Thx!!!

    • Ashton posted on May 13, 2013 at 9:01 pm (#)

      I think it’s about 2 cups. I may be a little off there, but it won’t mess up the dessert if it’s not exactly 9 graham crackers worth. Methinks I need to re-make this recipe and measure it out exactly! ;)

  58. holly posted on May 18, 2013 at 8:34 am (#)

    I am going to put peanut butter chips in the crust

  59. Rachel posted on October 5, 2014 at 10:42 am (#)

    Will these stay good if you freeze them?

    • Ashton posted on November 4, 2014 at 3:52 pm (#)

      I’ve never tried that! But I do eat 7-layer bars from a local bakery that I know are kept frozen, and they are always delicious :)
