In a small saucepan over medium heat, melt the butter. Swirl the pan occasionally and continue cooking until the butter becomes foamy with audible crackling and popping noises. Once the crackling stops, swirl until nutty aromas develop, and amber brown bits form at the bottom, about 2 to 3 minutes after popping ceases. Transfer to a mixing bowl and stir in the sugars. Set aside to cool completely.
