Here's what you'll need:
1 cup sweetened flaked coconut
8 tablespoons (1 stick) unsalted butter
9 graham crackers (5 ounces), crushed
1 cup finely chopped walnuts
1 cup semisweet chocolate chips
½ cup white chocolate chips
½ cup butterscotch chips
1 (14-ounce) can sweetened condensed milk
Adjust the oven rack to the lower-middle position and preheat to 350 degrees. Spray a 9×13-inch baking pan with non-stick spray. Line the pan with parchment paper, leaving overhang to act as handles for lifting the bars out of the pan. Spray with non-stick spray.
Spread the coconut on a baking sheet and bake until the outer flakes just begin to brown, about 4 minutes. Pay close attention to it, as it can go from brown to burnt very quickly. Set aside.
Melt the butter and combine with graham cracker crumbs in a small bowl. Toss with your fingers until the butter is evenly distributed. Press the crumbs evenly onto the bottom of the prepared pan.
In order, sprinkle the walnuts, chocolate chips, white chocolate chips, butterscotch chips, and coconut over the graham crumbs. Pour the condensed milk evenly over the entire dish.
Bake until the top is golden brown, about 25 minutes. Cool in the pan on a wire rack to room temperature, about 2 hours.
Remove from the pan using the parchment handles, and transfer to a cutting board. Using a sharp knife, cut into 18 bars.
