In large skillet, melt butter over medium heat. Add toasted pecans and stir to coat. Add brown sugar, cinnamon and salt; continue to cook over medium heat, stirring constantly about 8 to 10 minutes.
Add bourbon; stir to combine and cook 1 to 2 minutes, mixing well. Remove skillet from the heat and pour pecans onto rimmed cookie sheet lined with parchment paper. Spread pecans into thin layer and let cool 20 minutes. Break mixture into bite-sized pieces and cool completely before packaging.
