Cinnamon Toast Crunch Treats Ingredients
A complete list of ingredients and amounts can be found in the recipe card below.
Cinnamon Toast Crunch cereal: You need a whole box to make a tray of cereal bars (buy a family size box online if you’ve run out!)
Salted butter: You could use margarine but it won’t taste anywhere near as delicious!
Mini marshmallows: Your choice of pink and white, just white or colorful marshmallows.

Melt butter and marshmallows: Put the marshmallows and butter in your biggest mixing bowl and microwave until melted. Stir until smooth.
Add cereal: Pour the Cinnamon Toast Crunch into the melted marshmallow mixture and stir well to combine.
Press the mixture into a sheet pan: Gently press the mixture into a greased baking sheet and leave it set.
Slice and serve: After an hour or so, you can cut it into bars and enjoy.
Substitutions and Variations
Cinnamon Toast Crunch: Use any kind of cereal you want. Classic Rice Krispie treats fans might like to use Rice Krispies or you could try Chex cereal, Corn Flakes, Cocoa Puffs, or Golden Grahams. Alternatively, mix and match two or more types of your favorite cereal together.
Mini marshmallows: Use any color. You can swap in some marshmallow fluff, although it’s softer than marshmallows so using only marshmallow fluff will result in bars that are too soft to hold together.
Butter: Margarine would also work. Don’t sub coconut oil, as these bars are kept at room temperature and coconut oil won’t hold the bars together properly.
More add-ins: Include anything else you like in the cereal mixture, such as vanilla extract, chocolate chips or butterscotch chips. Melted white chocolate would be good with the gooey marshmallows too.
Serving Suggestions
As a sweet snack: Enjoy one of these bars with some state fair style lemonade or an iced gingerbread latte.
For dessert: A tasty treat after any kind of meal from cowboy stew to marry me chicken meatballs.
For gifting: Wrap a few of these bars in cellophane and tie with a bow. You could also add some to a personalized gift basket with other homemade goodies.
How to Store Cinnamon Toast Crunch Marshmallow Treats
Store: Keep leftovers covered with plastic wrap or in an airtight container at room temperature and eat within 3 days. You can separate the layers with parchment paper if you’re concerned about them sticking together.
Freeze: Don’t freeze these (or refrigerate them) as they’ll go rubbery or soggy.
Top Tips
Don’t skip the greasing: Spraying your baking dish with nonstick spray ensures the bars don’t stick and break apart when you try to remove them.
Work quickly: As soon as you take the melted marshmallow mixture out of the microwave, it starts to set, so work fast when pressing the mixture into your prepared pan.
No extra-large mixing bowl? Just make half the recipe and let the bars set, then make the other half and layer on top of a sheet of parchment paper on top of the first batch.
Cinnamon Toast Crunch Bars Recipe FAQs
Sure, just halve the ingredient amounts and use the same size baking dish and they’ll come out thinner.
It’s a very sticky mixture. I like to spray one of my hands with nonstick spray to make this step quicker and easier.
I haven’t tried this but you could use a large pot over a medium low heat and stir the mixture all the time until it melts.
