Grab two large baking sheets and cover them with parchment or wax paper. Measure everything out ahead of time. Toast the pecans for a nuttier taste if you'd like, then cool them fully.

Dump the white sugar, brown sugar, evaporated milk, corn syrup, and butter into a big sturdy saucepan. Put it over medium to high heat, stirring nonstop, until it melts into a creamy blend.

Turn up the heat and bring the mixture to a fast, steady boil. Stir often so it doesn't burn. Boil for 3 minutes while still mixing. It'll thicken and turn golden.

Take the pot off the heat right away. Stir in the vanilla and salt quickly but carefully—it might bubble a little. Mix it in until it's fully blended.

While the mixture's still hot, toss in the coconut flakes and pecans. Stir as fast as you can for 3 to 4 minutes. It'll start getting thicker and tougher to mix as it cools down.
