Preheat your oven to 350°F (175°C).
Grease a 9x13 inch baking pan with melted butter or line with parchment paper.
In a large mixing bowl, combine the graham cracker crumbs, melted butter, and vanilla extract. Stir until well-coated.
Press the crumb mixture firmly into the bottom of the prepared baking pan.
Sprinkle the shredded coconut and salted peanuts evenly over the crust.
In a microwave-safe bowl, combine the chocolate chips and sweetened condensed milk. Microwave in 30-second intervals, stirring until melted and smooth.
Pour the melted chocolate mixture over the coconut and peanut layer, spreading it evenly.
Bake for about 25-30 minutes, until the edges are golden brown and the center is set.
Cool on a wire rack, then refrigerate for 1 hour before cutting into squares or bars.
