How to Make It
Melt butter in a medium skillet over medium. Add brown sugar, and cook, stirring constantly, until sugar has mostly dissolved and mixture is almost smooth, about 3 minutes. Stir in pecans. Cook, stirring constantly, until mixture is completely smooth and pecans are coated, 1 to 2 more minutes. Spread pecans on parchment paper or wax paper, and cool completely, about 30 minutes.
