Put a large skillet over medium- high heat, and add the brown sugar, kosher salt, unsalted butter, and maple syrup.
Heat the ingredients, stirring when the butter starts melting.
Keep stirring until the maple syrup is completely smooth, about 3 minutes-4 minutes. Stir in the pecans, then remove the skillet from the heat.
Spoon this delicious praline syrup over your Belgian waffles, and serve immediately.
