Preheat the oven to 350 degrees F.
Slice the butter into a 9X13 pan and place the pan in the oven to melt the butter.
As soon as the butter is melted, remove the pan from the oven and sprinkle the graham cracker crumbs evenly on top of the melted butter.
Evenly distribute the Nestle Toll House DelightFulls on top of the graham cracker crumbs.
Next, add the butterscotch chips, then the coconut and then the chopped walnuts.
Drizzle the can of sweetened condensed milk evenly over the top.
Bake for 25 minutes.
Let cool before cutting into bars. Enjoy!
