Cinnamon toast crunch bars are an easy, no-bake dessert made with just 3 ingredients. They’re soft, gooey, and packed with that classic cinnamon sugar crunch everyone loves. Perfect for parties, potlucks, or an easy sweet snack.
Spray a 13" x 9" pan with cooking spray and line it with parchment paper, leaving some extra paper over the sides.
Melt butter over medium heat in pot. Once it's melted, reduce the heat to low.
Add marshmallows to the pot. Spray a mixing spoon with cooking spray and continuously stir until marshmallows are fully melted.
Remove the pot from the heat and add the cereal. Stir well to combine.
Pour the mixture into the prepared pan. With an additional piece of parchment paper, gently press it down into an even layer in the prepared pan (you may need to hold the bottom paper in place to keep it from moving all around).
Cool completely and once set, pull the bar out of the pan in once piece using the parchment paper and slice. Store in an air tight container and enjoy!

Notes
Line your pan before you start. I spray a 9 x 13 pan with cooking spray and add parchment paper with a little overhang so I can lift the bars out in one piece and slice them easily.
Keep the heat at medium when melting the butter and marshmallows. Higher heat can scorch them and will give you hard, brittle bars instead of soft and gooey ones.
A little cooking spray on your spoon goes a long way. Marshmallows are super sticky, and this makes stirring much easier.
Let the marshmallows melt completely. It takes a little patience, but the texture turns out so much smoother when they’re fully melted.
Be gentle when pressing the mixture into the pan. Packing it down too firmly can make the bars hard and dense instead of soft and chewy.
Ingredients to prep ahead- Measure everything before you start. Once the marshmallows are melted, things move quickly.
Leftovers and storage- Keep the bars in an airtight container at room temperature for up to 3 days. Place parchment paper between layers to prevent sticking. Freezing isn’t recommended, since it can affect the texture.
