Preheat the oven to 350 degrees F.

Place the butter in a glass or ceramic 9×13? pan, and put it in the oven for 2-3 minutes to melt.

Remove from oven and add graham cracker crumbs. Pat down to create base layer.

Sprinkle shredded coconut, then chocolate chips, butterscotch chips, and chopped nuts over the graham cracker layer.

Drizzle the sweetened condensed milk over the top.

Bake at 350 for 25-30 minutes, or until the condensed milk has soaked into the bars and the edges are golden.

Run a knife around the edges of pan while still warm to prevent cookies from sticking to edges. Slice into small squares while still warm.
