Preheat your oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper.
Combine the graham cracker crumbs and melted butter in a medium-sized bowl, stirring until well mixed.
Press the graham cracker mixture firmly into the prepared pan to create an even layer.
Evenly sprinkle semi-sweet chocolate chips, white chocolate chips, butterscotch chips, and chopped pecans over your crust.
Pour sweetened condensed milk evenly over the chocolate chip mixture.
Sprinkle shredded coconut in an even layer over the condensed milk.
Bake for about 20–25 minutes or until golden brown on top.
Let your bars cool completely in the pan before slicing them into squares.
