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:
- Preheat your oven to 400°F (200°C). Line a 12x17 inch jelly roll pan with aluminum foil and top with parchment paper.
- Arrange the saltine crackers in a single, tight layer on the prepared baking sheet.
- In a medium heavy-bottomed saucepan, combine the unsalted butter and light brown sugar over medium heat.
- 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.
- Carefully pour the hot toffee mixture over the crackers and spread evenly using an offset spatula.
- Bake in the preheated oven for 5 minutes. The toffee should be bubbling vigorously.
- 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.
- Allow to cool completely at room temperature, then refrigerate until set before breaking into pieces.
