Ingredients:

  • 48 saltine crackers (approx. 130g)
  • 1 cup unsalted butter (225g)
  • 1 cup light brown sugar, firmly packed (200g)
  • 2 cups semi-sweet chocolate chips (340g)

Instructions:

  1. Preheat your oven to 400°F (200°C). Line a 12x17 inch jelly roll pan with aluminum foil and top with parchment paper.
  2. Arrange the saltine crackers in a single, tight layer on the prepared baking sheet.
  3. In a medium heavy-bottomed saucepan, combine the unsalted butter and light brown sugar over medium heat.
  4. Stir constantly until the butter is melted. Once the mixture begins to bubble, stop stirring and start a timer for exactly 3 minutes of a rolling boil to ensure proper emulsification.
  5. Carefully pour the hot toffee mixture over the crackers and spread evenly using an offset spatula.
  6. Bake in the preheated oven for 5 minutes. The toffee should be bubbling vigorously.
  7. Remove from the oven and immediately sprinkle the chocolate chips over the hot toffee. Let sit for 1-2 minutes until softened, then spread into a smooth layer.
  8. Allow to cool completely at room temperature, then refrigerate until set before breaking into pieces.
