Cinnamon Toast Crunch Bars


We have a permanent craving for sugary cereal in our house. It’s a problem. Whenever we finally cave in and buy some at the store, Cinnamon Toast Crunch is always my go-to.

This time when I brought the box home, I thought, “How can I make these a little more interesting?” Rice Krispie Treats are also one of my faves, so I figured I’d mash those two together! I know, this is not a brand new idea. I got to googling and found Pilsbury’s recipe. But after making them we felt like they were missing something – cinnamon! The cinnamon flavor from the cereal itself got lost in the sweetness of all the marshmallows, and the whole thing just tasted a little flat.

The original recipe was a great starting point, and after a few tweaks I felt like these are perfect! Cinnamon Toast Crunch Bars are an easy, no-bake recipe when you need something quick. And kids will love ’em!

The Goods

Butter: I added a half tablespoon more than the original called for. I realized that the cinnamon was absorbing some of the butter, which made melting the marshmallows a little difficult. Throwing a little extra in there with the ‘mallows helped get everything smooth and silky.

Salt: I used Diamond Crystal salt. If you are using Morton’s, I would throw it in a little earlier to give it more time to dissolve, and scale back to ⅛ teaspoon instead.

Cinnamon: Adding extra to this really brought it to life. I don’t recommend using cinnamon sugar, since the cereal and marshmallows are so sweet themselves.

Cereal: I measured mine in volume with a food scale. If you buy a regular sized box you probably won’t have to do this, but I bought the family size so I’d have some cereal left over for breakfast (don’t judge me).

Vanilla: If you don’t have any, I wouldn’t worry about it. You can continue with this recipe without it, but it does add a nice depth of flavor to these simple bars.


Cinnamon Toast Crunch bars very, very sticky. They’re pretty hard to manage without cooking spray. After tipping them into the pan, spray your rubber spatula or potato masher with cooking spray. Gently push the bars into an even layer, making sure not to press too hard. You can use your hands too, just make sure to wet your fingers with water or spray with cooking spray too.

30 minutes is the minimum amount of time these need to set. The first time I made them, I cut them pretty much right at the 30 minute mark. I was able to get them out of the pan, but they were still pretty soft and fell apart easily when eating. If you have the time, try and let these sit for 45 minutes to an hour so they’re easier enjoy.

I cut these into 2×2 inch squares, but feel free to make them any size you want!

Don’t stop here! Add whatever you’re craving to these. You can mix in some whole, unmelted mini marshmallows, combine two cereals or maybe some sprinkles! Leave a comment below and tell me how you chose to enjoy them!
