  • 4 cups Rice or Corn Chex
  • 2 cup Saltine minis
  • 1 cup assorted unsalted or lightly salted nuts*
  • 1 cup pretzel sticks or mini knots
  • 1/2 cup unsalted butter
  • 1 cup dark brown sugar
  • 6 tablespoons light corn syrup
  • 1/2 teaspoon kosher salt
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda


  • Position rack in the center of your oven. Preheat to 225 F. Line a large rimmed baking sheet with a silicone baking mat.**
  • In a large mixing bowl, combine cereal, nuts, Saltines, and pretzels. Set aside.
  • Place a large saucepan over medium heat, and melt the butter.***
  • Once the butter has melted, stir in the brown sugar, corn syrup, and salt.
  • Bring the mixture to a boil, stirring frequently.
  • Allow the mixture to boil for 2 minutes, and then remove from the heat.
  • Whisk in vanilla extract, and then add the baking soda, mixing well. The toffee will foam. Continue whisking until well-combined. 
  • Pour the hot toffee over the cereal mixture, and carefully fold to coat the cereal mixture with the toffee mixture. The cereal mixture doesn't have to be perfectly coated.
  • Spread the cereal mixture in an even layer on the prepared baking sheet.
  • Bake 15 minutes. 
  • Carefully stir the cereal to coat with melted toffee.
  • Continue baking for 15 minutes, stir, and then bake for another 10-15 minutes. 
  • Remove from oven, and then toss one more time. 
  • Spread into an even layer, and let cool. 
  • Break into pieces to serve. 


*You can swap in an extra cup of cereal, crackers, or pretzels in place of the nuts. 
**I use a half sheet pan. If you don't have a baking sheet that's that large, use two smaller baking sheets. 
***You'll need a pan that will give you enough space for the toffee to foam up when you add the baking soda.
