In a large saucepan, combine butter, brown sugar, honey and salt. Cook over medium heat, stirring frequently, until bubbly and thickened, about 6 to 7 minutes.
3/4 cup unsalted butter, 1 cup brown sugar, 1/2 cup honey, 1 tsp salt
Add the heavy cream and cook, stirring constantly, until a candy thermometer inserted into the caramel reaches 240°F (soft-ball stage), about 10 minutes.
1 cup heavy cream
Remove from the heat and stir in the pecans until evenly coated.
2 cups pecan halves
Pour the caramel pecan mixture over the crust and spread evenly. Bake for 15 minutes, or until the filling is bubbly.
Let cool completely before lifting from the pan and cutting into squares.
