In a small saucepan, combine maple syrup, brown sugar, and salt. Heat over medium heat. Stir constantly until brown sugar is melted and mixture is foamy.

Add pumpkin seeds and stir until coated.

Spread pumpkin seeds on oiled cookie sheet. Bake for 10 minutes, stirring after 5 minutes. Remove from oven and cool completely; stir occasionally while cooling to prevent pumpkin seeds from sticking to pan.
