Crunchy Caramel Chocolate Layer Bars

Preheat the oven to 350°F (175°C). Crush the graham crackers into fine crumbs and mix them with melted butter and brown sugar. Press the mixture into the bottom of a greased baking pan. In a saucepan, combine the sweetened condensed milk and peanut butter. Heat over low heat until the mixture becomes smooth and creamy. Pour the peanut butter mixture over the graham cracker crust in the baking pan. Spread it evenly. Sprinkle the semi-sweet chocolate chips over the peanut butter layer. Bake in the preheated oven for 20-25 minutes or until the edges start to turn golden brown. Remove from the oven and let it rest for 60 minutes to cool and set. Drizzle caramel sauce over the top and sprinkle crushed peanuts. Cut into bars and serve.
