Ingredients
  

Main Ingredients

  • 6 cups Chex cereal
  • 1/2 cup unsalted butter
  • 1/2 cup packed light brown sugar
  • 1/4 teaspoon vanilla extract optional
  • Pinch salt

Optional Additions

  • 1 cup mixed nuts (pecans, almonds)
  • 1/2 cup pretzels
  • 1/2 cup chocolate chips after baking

Instructions
 

Preparation

  • Preheat your oven to 250°F (120°C) and prepare a large baking sheet by lining it with parchment paper or a silicone baking mat.

Combine Ingredients

  • In a very large microwave-safe bowl, combine the Chex cereal, and if using, add any nuts or pretzels.
  • In a separate microwave-safe bowl, melt the butter, then stir in the brown sugar until combined, and microwave for 1 minute.
  • Stir well after 1 minute, and continue microwaving for another 30 seconds to 1 minute until bubbling and the sugar has dissolved, then stir in the vanilla extract (if using) and salt.

Coating and Baking

  • Pour the hot toffee sauce over the cereal mixture and stir gently but thoroughly until all pieces are evenly coated.
  • Spread the coated cereal in a single layer on the prepared baking sheet and bake for 1 hour, stirring every 15 minutes.
  • Remove from the oven and allow it to cool completely on the baking sheet to achieve a crisp texture.

Finishing Touches

  • Once completely cool, if using, sprinkle with chocolate chips and gently toss.
  • Break the cooled Toffee Chex Mix into clusters and serve.

Notes

For an extra touch of flavor, you can add a pinch of cinnamon to the toffee sauce. Ensure the Chex Mix cools completely for maximum crispness. Store in an airtight container for up to a week.
