Ingredients Equipment Method Notes

Ingredients
  

  • 1 cup unsalted butter
  • 1 cup packed brown sugar
  • 1/2 cup sweetened condensed milk
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 6 cups cornflakes cereal

Equipment

  • 1 Baking Sheet
  • 1 Saucepan
  • 1 Large Bowl

Method
 

  1. Line a large baking sheet with parchment paper and set aside.
  2. In a medium saucepan, combine the butter, brown sugar, and sweetened condensed milk. Cook over medium heat, stirring constantly, until the butter melts and the sugar dissolves.
  3. Bring the mixture to a boil and cook for 5-7 minutes, continuing to stir, until the toffee thickens and turns a deep amber color.
  4. Remove from the heat and immediately stir in the vanilla extract and salt.
  5. Place the cornflakes in a large heatproof bowl. Pour the hot toffee over the cornflakes and fold gently with a spatula until evenly coated.
  6. Working quickly, drop heaping tablespoons of the mixture onto the prepared baking sheet.
  7. Allow the cookies to cool and set completely at room temperature, or chill in the refrigerator for 20-30 minutes for a faster set.

Notes

Work quickly once the toffee is ready as it will start to set almost immediately.
For an extra treat, drizzle melted chocolate over the top of the cooled cookies.
