Ingredients Method Notes

Ingredients
  

  • 8–9 cups Chex cereal Rice Chex or a mix of Rice & Corn
  • 1 ½ cups nuts pecan halves or walnuts
  • 1 cup unsalted butter
  • 1 ½ cups packed brown sugar light or dark
  • ½ cup light corn syrup
  • 1 tsp alcohol-free vanilla extract or vanilla powder
  • 1 tsp baking soda crucial for toffee texture
  • ½ tsp fine salt

Method
 

  1. Preheat the oven: Set oven to 250°F (120°C). Line a large rimmed baking sheet (or two) with parchment paper.
  2. Prepare the cereal mix: Add Chex cereal and nuts to a very large heatproof bowl. Warm the bowl slightly to prevent the toffee from seizing.
  3. Make the toffee: In a medium saucepan, melt the butter with brown sugar and corn syrup over medium-high heat, stirring until smooth. Bring to a rolling boil and boil for 5 minutes without stirring.
  4. Add flavorings: Remove from heat and whisk in vanilla, salt, and baking soda. The mixture will foam and expand.
  5. Coat the cereal: Immediately pour the foaming toffee over the cereal and nuts. Fold quickly until everything is evenly coated.
  6. Bake: Spread the mixture onto prepared baking sheet(s). Bake for 45–60 minutes, stirring every 15 minutes, until dry and crisp.
  7. Cool and serve: Allow to cool completely for 30–45 minutes. Break into bite-sized pieces and store airtight for up to 1 week.

Notes

For extra indulgence, drizzle with melted chocolate after baking and cooling.
