Ingredient Notes

• Cinnamon Toast Crunch cookie dough – Using the refrigerated dough makes these bars quick and foolproof. You can usually find it in the refrigerated section near other cookie doughs.
• Mini marshmallows – They melt down smoothly for that gooey, stretchy layer. You can swap in large marshmallows if that’s what you have on hand, just chop them up first.
• Cinnamon Toast Crunch cereal – Crushing the cereal lightly (not into crumbs) gives the topping its signature crunch. Feel free to add a little extra for a thicker layer.
• Caramel sauce – Store-bought caramel works great here, but homemade caramel or a salted caramel drizzle will take these bars over the top.
• Cinnamon sugar – Just a pinch ties all the flavors together and adds a little sparkle to the finish.

Before You Bake

Do I need to spray the pan if I’m using parchment paper?
Yes, a light coat of baking spray helps keep the cookie base from sticking, especially at the edges. It also makes it easier to lift the bars out cleanly for slicing.

How long should I let the cookie base cool before adding marshmallows?
Just 5–10 minutes. You want it slightly cooled so the marshmallow layer spreads smoothly without sinking into the cookie.

Can I crush the cereal ahead of time?
Absolutely. Crush it lightly (not into crumbs) and keep it in a sealed bag so it stays crisp until you sprinkle it on.

FAQ

Can I make Cinnamon Toast Crunch marshmallow bars ahead of time?
Yes. These bars keep well covered at room temperature for up to 2 days, or in the fridge for 4–5 days.

How do I keep the bars from sticking to the knife when slicing?
Spray a sharp knife with nonstick spray or wipe it with a little butter. You can also warm the knife under hot water and dry it before each cut.

Can I freeze these bars?
Yes. Wrap tightly in plastic wrap and place in a freezer bag. Freeze for up to 2 months and thaw at room temperature before serving.

What’s the best way to crush Cinnamon Toast Crunch cereal?
Place the cereal in a zip-top bag and use a rolling pin or the bottom of a measuring cup to gently crush. Aim for chunky pieces, not fine crumbs.

Can I use a different cookie dough flavor?
Definitely. Sugar cookie dough, snickerdoodle dough, or even chocolate chip would all pair deliciously with the marshmallow and cereal layers.
