Step-by-Step Instructions
My process always starts with the pan. I line my jelly roll pan completely with foil or parchment paper, making sure it goes up the sides. This isn’t just for cleanup; it’s our handle for lifting the whole slab of candy out later. I then lay out the saltine crackers in a single, snug layer, covering the entire bottom of the pan. I break a few to fill in the gaps. The sound of the crackers settling is a satisfying start. I preheat my oven—this recipe uses the broiler at the end, so I set it to 350°F to start for even heating.
Now, for the heart of the candy: the toffee. In my medium saucepan, I melt the butter over medium heat. Once it’s melted, I stir in the packed brown sugar. I bring the mixture to a boil, stirring constantly. Once it’s at a full, rolling boil, I set a timer and let it boil for exactly 3 minutes, stirring continuously. The mixture will thicken and become a gorgeous, deep caramel color. I can smell the sugar caramelizing—it’s a rich, buttery scent. The moment the timer goes off, I remove the pan from the heat and stir in the vanilla extract. It will sizzle and foam up wonderfully.
Working quickly, I carefully pour the hot toffee mixture evenly over the waiting saltines. I use my spatula to gently spread it to cover every cracker. This is a thrilling step; you can hear the crackers start to absorb the hot liquid. I then slide the entire pan into the preheated oven. I bake it for 5 minutes. This short bake helps the toffee really soak into the crackers and set the foundation. The smell of baking toffee and crackers is incredible—warm and buttery.(See the next page below to continue…)
