Preheat your oven to 350°F (175°C).
Place the unbaked pie crust on a baking sheet for easy transfer in and out of the oven.
In a big ol’ mixing bowl, stir together the coconut, pretzels, chocolate chips, toffee bits, and pecans.
Pour in the sweetened condensed milk and stir until everything's coated and clumpy in the best way.
Dump that beautiful mess into your pie crust and spread it out evenly.
Bake for about 45 minutes or until the top is golden and set. You want it firm, not jiggly.
Let it cool completely before you even *think* about slicing. It needs time to become the sticky, chewy wonder it's meant to be.
