Preparation Steps

• Preheat oven to 350°F (175°C). Line a 9x13-inch baking sheet with aluminum foil and spray with non-stick spray.
• Arrange saltine crackers in a single layer to cover the entire baking sheet.
• In a saucepan, melt the butter and brown sugar over medium heat, stirring until the mixture reaches a boil. Let it boil for 3 minutes without stirring. Remove from heat and stir in vanilla.
• Pour the hot mixture evenly over the crackers and spread to cover completely.
• Bake for 5 minutes in the preheated oven, or until the toffee is bubbly.
• Remove pan from oven and immediately sprinkle chocolate chips over the top. Let sit for 5 minutes to soften, then spread into an even layer.
• Sprinkle chopped pecans over the chocolate layer.
• Cool in the refrigerator until set, then break into pieces and serve.
