Easy Cinnamon Toast Crunch Treats

If you’re looking for a new twist on an old treat, one you can make with the kids, this is it! These simple Cinnamon Toast Crunch treats are reminiscent of Rice Krispy treats, with made with a favorite cinnamon cereal, instead! 

Why use Cinnamon Toast Crunch in this Treat?

My plan started on a Saturday morning. The grandkids were due to come to my house to make Nutella Christmas trees and Peppermint Meringues. 

I hadn’t really planned to make cereal treats, but I knew the girls would be hungry and it seemed like a simple remedy. 

I didn’t have any Rice Krispies on hand but I had a brand new box of Cinnamon Toast Crunch, my all-time favorite cereal. 

These delicious cereal squares are loaded with cinnamon sugar flavor and are crunch and delicious. 

Something told me they would be perfect as breakfast treats. 

The Best Recipes come from the Imagination

I’m so glad I decided to tap into mine and make these treats! As you will see from the pictures, I got the girls involved in the process every step of the way and they had a blast. 

And, can I just say, it wasn’t just the kids who loved the outcome. The adults in the room flipped over these cinnamon-sugary bars, too! (In fact, I’m almost ready to proclaim that they’re even better than Rice Krispy treats! Almost!) 

I’ll share more about my thoughts later, but let’s break down what you’ll need to make these. 

Cinnamon Toast Crunch Treats

You will find a full printable recipe card at the bottom of this post but here’s a quick peek at what you’ll need. These are simple ingredients you might have on hand in your kitchen. 

• Cinnamon Toast Crunch cereal
• miniature marshmallows
• butter (salted or unsalted, your choice) 

That’s it! Just three ingredients! 

How to make Cinnamon Toast Crunch Treats

These come together in (literally) minutes. You’re not going to believe how quick and easy they are! 

Start by buttering a 9×13-inch baking dish. 

Place mini marshmallows and 3 tablespoons of butter into a large bowl and melt in the microwave. We did ours in one-minute increments, stirring in-between, until it was all melted. 

Now it’s time to pour the cereal into that gooey marshmallow mixture. 

Mix well to coat all of the pieces. 

Now for the fun part. (As you will see from the photos, it took a village at my house to accomplish this part of the process.) 

Dump the gooey mixture into the prepared pan. Now butter your hands and press the cereal down until it’s level. This won’t be easy because the pieces are squared, but do your best. 

You’ll be tempted to dive right in (ahem) but if you can wait a bit, they’re easier to cut. I must warn you, the temptation is overwhelming!

Clearly, we didn’t wait. Cover with foil or plastic wrap (or place in an airtight container). Set aside.

After they’ve set up (half an hour or so) cut and serve. 

Cover with plaster wrap and store at room temperature up to 5 – 6 days. 

What to Expect from these Cinnamon Toast Crunch Treats

Y’all, these are delicious. They’re very much like classic rice krispie treats but with a cinnamon twist!

I actually think I loved the cinnamon flavor the most. It merged so beautifully with the melted marshmallow. Talk about the perfect no bake dessert!

I also loved the “crunch” of the cereal. These larger squares of cereal offered a completely different experience than tiny Rice Krispies. I thoroughly enjoyed it. 

And I was tickled pink that the kids did, too. (You never know when you dream these things up how they will be received, but this one got rave reviews.) 

Check out those gooey marshmallows!

I plan to make this again and again. No kidding. It’s such a simple and delicious treat! 

Variations on these Marshmallow Treats

I’m already thinking of fun variations, y’all. Here are some other cereals that would work for easy treats: 

Fruit Loops: I think they would make delicious treats! Use the exact same measurements and instructions. (The cereal mixture will be colorful and fun!)

Cocoa Puffs: Chocolate and marshmallow? Yes, please! I might also throw in some Golden Grahams to give these a S’Mores flavor! (3 cups of each cereal) 

Lucky Charms: For a fun twist, use this bright and colorful cereal! I think the little marshmallow bits in this cereal bars would be great! 

Honey Nut Cheerios: This would be a delicious combination! 

Fruity Pebbles: Fruity Pebbles treats sound amazing. Best of all, they would have that same familiar crunch you’re used to in regular rice krispie treats.

Have a blast on the cereal aisle, y’all! There are probably a ton of options I haven’t even thought of.

Questions People are Asking:

Can I use marshmallow fluff in place of miniature marshmallows?

You can, but you might need to soften it in the microwave for a few seconds first.

I only have large marshmallows. Can I use those?

You can, but they will take a little longer to break down. Make sure there are no lumps before stirring in the cereal.

Can I add chocolate chips to this no bake treats recipe?

You can. Chocolate and cinnamon pair well together and chocolate takes everything to a whole new level! But I would suggested using mini chocolate chips, as regular sized ones would be quite a mouthful!

Are these Cinnamon Toast Crunch cereal bars good lunch box treats?

They are but they need to be tightly wrapped to stay fresh.

Do I have to use regular marshmallows? Can I use flavored?

You can use whatever flavors you like in these fun cereal bars. Just make sure those flavors merge nicely with whichever cereal you choose.
