You Can Substitute Maple Syrup For Sugar, But Follow One Rule - Tasting Table
Briefly

Maple syrup serves as a nutritious alternative to sugar in baking, boasting a lower glycemic index and beneficial antioxidants and minerals. It enhances flavor, especially in recipes like carrot cake or pumpkin bread. For optimal results, it is crucial to use room temperature syrup to prevent clumping and emulsion breakage, especially in butter-based recipes. The substitution ratio is ¾ cup syrup for 1 cup sugar, with a recommendation to reduce other liquids. Pure maple syrup has a long shelf-life, ensuring freshness for extended periods.
Not only does maple syrup have a lower glycemic index than white sugar, but research also suggests that it contains antioxidants and important minerals.
You can use about ¾ cup of room temperature syrup for every cup of sugar and should reduce other liquids by a few tablespoons.
