Quick Answer
Maple Syrup does not use the same grams-to-cups value as every other ingredient. Using a practical US cup reference, 322 grams of maple syrup is about 1 cup.
That means 100 grams of maple syrup is about 0.31 cups, while 200 grams is about 0.62 cups.
Maple syrup is a dense liquid sweetener, slightly lighter than honey but much heavier per cup than dry baking ingredients.
