Units Scale
  • 7 cups Cinnamon Toast Crunch cereal, coarsely crushed
  • 10 oz marshmallows
  • 4 tbsp unsalted butter
  • 1/2 cup sweetened condensed milk


  1. In two batches, coarsely crush the cereal in a large ziploc by gently rolling a rolling pin over the bag.
  2. In a large pot, melt the butter over low-medium heat.
  3. Add the marshmallows and continue cooking until the marshmallows have melted completely.
  4. Remove the pot from the heat and stir in the sweetened condensed milk until combined.
  5. Add the crushed cereal, folding until it's completely coated.
  6. Spoon into a greased 9"x13" dish and allow to set for at least 3 hours, preferably overnight.


  • Cooking cereal bars: Make sure to cook your butter/marshmallows over low-medium heat and to remove them from the heat immediately once melted to avoid overcooked, hard bars.
  • Sweetened condensed milk: The sweetened condensed milk in this recipe creates a milky cereal flavor and an extra soft bar. If you prefer something closer to a traditional rice krispie treat texture, you can omit the sweetened condensed milk and reduce the cereal by one cup.
  • Setting time: Because of the soft texture of these bars, they require extra setting time. I recommend letting them set overnight when possible.
  • Thick cereal bars: If you like an extra thick cereal bar, you can make this recipe in a 8"x8" square pan. Be sure to allow at least five hours, if not overnight, for setting.
  • Storage: Cereal bars can be stored in an air tight container at room temperature and are best when eaten within three days. If you slice them up, be sure to place parchment paper between layers to keep them from sticking together.
