How to Make Cinnamon Toast Crunch Treats

Step 1: Prep Your Pan
 Spray a 9×13 baking dish with nonstick spray. This will make removing the treats (and cleaning up) much easier later.

Step 2: Melt Butter and Marshmallows
 Cut the butter into tablespoon-sized pieces. Add it to an extra-large mixing bowl along with both bags of mini marshmallows. Microwave for 2 minutes and 30 seconds or until the marshmallows puff up close to the top of the bowl.

Step 3: Stir Until Smooth
 Carefully remove the bowl from the microwave (it will be hot.) Stir immediately until the mixture is smooth and no chunks of marshmallow or butter remain. If needed, microwave again in 10-second intervals to melt any stubborn pieces.

Step 5: Press into Pan
 Pour the cereal-marshmallow mix into the prepared baking dish. Spray your hands or a spatula with cooking spray, and press the mixture down evenly and firmly into the pan.

Step 6: Let It Set
 Let the bars rest at room temperature for about 1 hour or until fully set. Once cooled, cut into squares and enjoy.

Tips for the Best Cereal Marshmallow Bars

  • Don’t refrigerate: These treats should be stored at room temperature. Refrigeration will make them rubbery and hard to chew. Store in an airtight container for up to 3 days.
  • Smaller batch? Cut the recipe in half for thinner bars or fewer servings.
  • No XL bowl? Make half the batch at a time and layer both halves in the same pan. The final result will be just as delicious.
  • Brand options: While name-brand Cinnamon Toast Crunch delivers that classic flavor, any cinnamon-toast-style cereal will work for this recipe.
  • Hands-on pressing: Spray your hands with nonstick spray before pressing the mixture into the pan to avoid sticky messes and make shaping easier.
