3-Ingredient Cinnamon Toast Crunch Treats
These cinnamon toast crunch treats turn your favorite cereal into a chewy, no-bake snack bar you can throw together in minutes. A warm swirl of cinnamon sugar coats every bite, giving them a spiced crunch that regular cereal bars just don’t have.
They need only butter, marshmallows, and cereal, so the ingredient list stays short and the craving gets solved fast.
Why These Treats Work
The cereal already has a baked-in cinnamon sugar flavor, so no extra spices are needed. That toasty, buttery coating intensifies as the marshmallow mixture melts around it, creating a soft, chewy center and crisp edges in the same bite.
They set up in about an hour and cut cleanly, making them a reliable last-minute snack for movie night, lunchboxes, or a quick dessert tray. Because the recipe is so forgiving, the texture stays soft for days when stored properly.
Ingredients
- 4 tbsp unsalted butter: salted works too; just skip any added salt.
- 10 oz mini marshmallows: fresh marshmallows melt the smoothest; stale ones can seize.
- 6 cups Cinnamon Toast Crunch cereal: measure lightly packed so the bars hold the right ratio of crunch to chew.
- 1/2 tsp vanilla extract: rounds out the sugar and butter warmth.
- Pinch of flaky salt: if your butter is unsalted, a tiny sprinkle sharpens the sweetness without tasting salty.
Variations / Substitutions
- Make them dairy free: swap the butter for refined coconut oil and use vegan marshmallows. The texture stays just as soft, and the coconut taste is mild enough that it fades behind the cinnamon.
- Add white chocolate chips: fold in 1/2 cup of chips right after the cereal so they melt a little but keep small pockets of creaminess.
- Go for extra crunch: mix in a handful of toasted pecans or almonds along with the cereal.
- Use marshmallow fluff: replace the marshmallows with one 7 oz jar of fluff and reduce the butter to 3 tbsp. The bars come out slightly thinner and stickier, so a greased spatula is your friend.

How to Make Cinnamon Toast Crunch Treats
Step 1: Melt the Butter and Marshmallows
Place a large pot or Dutch oven over medium-low heat and toss in the 4 tbsp butter. Once the butter starts to foam, after about 2 minutes, pour in the 10 oz marshmallows and stir continuously. Keep the heat low enough that the marshmallows soften without browning; you want them to melt into a glossy, smooth sauce, which takes about 3 minutes of constant stirring.
You’ll see the mixture go from lumpy to a thick, shiny ribbon that slowly falls off the spoon. When it pulls away from the sides of the pot and no white streaks remain, it’s ready.
Step 2: Fold in the Cereal
Remove the pot from the heat and quickly stir in the 1/2 tsp vanilla and a pinch of salt. Immediately add the 6 cups of cereal all at once. Grab a heatproof spatula and fold from the bottom outward, scooping up the melted marshmallow so every square gets a thorough coating. This part moves fast and takes about 1 minute, so have your pan ready.
The mixture will look glossy and sticky but not runny, and the cereal pieces should still hold their shape. If you press a bit between your fingers it should clump together easily.
Step 3: Press and Slice
Lightly grease an 8-inch square baking pan and line it with parchment paper, leaving a little overhang on two sides. Scrape the cereal mixture into the pan and press it firmly into an even layer with a greased spatula or with damp fingertips. Press firmly enough so the bars hold together, but don’t pack them down so hard that they turn dense.
Let the pan sit at room temperature for about 1 hour until fully set. Then lift the whole block out by the parchment, set it on a cutting board, and slice into 12 bars. The edges will be crisp and the centers wonderfully chewy.
A Few Tips for Perfect Treats
- Line the pan with parchment, not just butter, so the block lifts out without sticking and you get clean cuts.
- Warm the vanilla extract to room temperature before adding it so the marshmallow mixture doesn’t seize from the cold shock.
- If the mixture starts to stiffen before you get it into the pan, warm it for 15 seconds over low heat while stirring. That loosens it right up.
- For extra neat bars, let them set completely, then run a sharp knife under hot water and wipe it dry between each cut.
Scale the batch to your pan size:
| Pan size | Cereal | Marshmallows | Butter |
|---|---|---|---|
| 8×8-inch | 6 cups | 10 oz | 4 tbsp |
| 9×9-inch | 5 cups | 8 oz | 3 tbsp |
| 9×13-inch | 8 cups | 14 oz | 5 tbsp |
Storing Leftover Treats
- Refrigerate: layer the bars between sheets of parchment in an airtight container; they stay soft for up to 5 days.
- Serve cold: right from the fridge they get a little firmer, but the cinnamon flavor still comes through strongly.
Frequently Asked Questions
Can I melt everything in the microwave?
Yes. Combine the butter and marshmallows in a large microwave-safe bowl, heat for 1 minute, stir, then heat in 30-second bursts until smooth and pourable. Fold in the cereal immediately.
What size pan works best?
An 8×8-inch pan gives you thick, chunky bars. A 9×9-inch makes them thinner and crispier. For a doubled batch, use a 9×13-inch.
Can I freeze them?
Absolutely. Wrap individual bars in plastic wrap and stack them in a freezer bag. They’ll keep for up to 2 months and thaw at room temperature in about 20 minutes.
Are these gluten free?
No, Cinnamon Toast Crunch contains wheat, so the treats are not gluten free. Look for a certified gluten free cinnamon cereal if you need a safe swap.
