And the monstrous fun continues with another Monsters University inspired treat! To celebrate this weekend’s opening of the new film, we had a little Monsters-theme playdate, complete with Mike Wazowski monster smoothies, Mike Wazowski monster apples, and these oh-so delicious cereal treat bars! Monsters Cereal Treat BarsWhile on our Monsters playdate shopping trip, Big Brother happened to spot a special edition Kellogg’s Monsters University cereal (think Lucky Charms). We don’t do much sugary cereal like that normally, but thought we could definitely turn it in to a special treat! And, that’s exactly what we did! No-bake, easy to make, super cute, and seriously delicious!! It’s as simple as making “krispie treat bars”.Monsters University Cereal


  • butter
  • marshmallows
  • Monsters University cereal (*Note- if you can’t find the cereal, you could always substitute with something else and use the sprinkles/food coloring/etc. to make it more “Monsters-ish”)
  • blue and green sparkling sugar sprinkles
  • candy eyeballs


First decide what thickness of cereal bar you’d like. Because I was making them for young kids, I decided to make them in a 9×13 pan to make them fairly thin. But, the “normal” recipe isn’t enough then. If you like them thicker, then I suggest a square 8×8 or 9×9 pan! So…

  • For thicker cereal bars in a square pan, use 3T butter, 4C mini marshmallows, and 6 cups of cereal!
  • For thinner bars in a 9×13, use about 1/4 C butter, 5-6 C mini marshmallows (almost the whole bag), and about 8 C cereal (almost the whole box).

Start by greasing whatever pan you’re using with some butter. Then, melt your butter in a pan on low heat with the marshmallows, stir frequently. Once that is gooey & melty, stir in the cereal until it’s all mixed together well. Spread into the greased pan and smooth down as best you can. I recommend spraying a little non-stick cooking spray on your hand or on a piece of foil for pressing everything down. Then, while everything is still warm, let the kids sprinkle blue & green sugar sprinkles all over the pan and sticking in some candy eyeballs for some added monster fun!!  Monster Cereal Treat BarsLet the bars cool to harden a bit, then cut and serve! Super easy and fun! And, be warned…these monster treats are scary good! So they might just disappear in a flash! Disney Monsters Cereal Treat Bars

  1. Any suggestions on where to buy the candy eyeballs? Would Michael’s or a place that stocks cake-decorating supplies have them?

    We are waiting for the movie to come to the drive-in theater near us. I think I will surprise my kids with these treats for our movie snack. Great idea, thank you for sharing it!

    1. Hi Mindy! I actually found them at Target and I’ve seen them at some Walmarts and JoAnns. Haven’t looked for them at Michael’s, but it’s a good bet! 🙂 Have fun at the drive-in! Glad you like the snacks! 🙂
