Preparation Steps

• Preheat the oven to 350°F (175°C). Line a baking sheet with aluminum foil and arrange saltine crackers in a single layer.
• In a saucepan, melt the butter over medium heat. Stir in the brown sugar and bring to a boil. Let it boil for 3 minutes while stirring constantly.
• Pour the hot butter and sugar mixture evenly over the arranged crackers.
• Bake the crackers for 5-7 minutes until bubbly and caramelized.
• Remove from oven and immediately sprinkle chocolate chips evenly over the hot toffee layer. Allow them to sit for 2-3 minutes to melt, then spread the chocolate smooth.
• Sprinkle mini marshmallows on top of the melted chocolate and bake for another 1-2 minutes until marshmallows are puffed and lightly golden.
• Allow to cool completely before breaking into pieces. Serve and enjoy!
