1. Preheat your oven to 350°F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
2. In a large, microwave-safe bowl, add the butter and heat on high power to melt, about 1 minute.
3. Add the graham cracker crumbs to the melted butter and toss lightly with a fork to coat crumbs evenly.
4. Turn mixture out into prepared pan, forming an even, smooth, flat crust layer by tapping crumbs into place with a spatula or your fingertips.
5. Evenly sprinkle with the semi-sweet chocolate chips and butterscotch chips; set aside.
6. To a small saucepan, add the Werther’s Original Soft Caramels, half-and-half or cream, and heat over low heat to melt, whisking constantly until melted.
7. Add the salt, stir to combine, and taste sauce. Depending on preference for saltiness, add more salt to taste.
8. Evenly drizzle the salted caramel over the semi-sweet chocolate chips and butterscotch chips.
9. Evenly sprinkle the sweetened shredded coconut flakes.
10. Evenly drizzle the sweetened condensed milk over the coconut.
11. Bake for about 22 to 25 minutes, or until lightly golden brown around edges and the center is mostly set.
12. Place pan on a wire rack and allow bars to cool in pan for at least 2 hours, or overnight, before slicing and serving.
