Molasses:
grams to cups.
Molasses weighs approximately 337 g per cup — nearly as dense as honey, reflecting its high sugar concentration. Molasses type (light, dark, or blackstrap) affects flavor intensity and mineral content but has only minor effects on density.

Three types of molasses and how extraction stage changes density
Molasses is the dark, thick byproduct of sugar cane refining. Light molasses comes from the first boiling of sugar cane juice and contains the highest sugar content (about 65–70% sugars), making it the sweetest and thickest — closest to 337 g/cup. Dark molasses comes from the second boiling, has less sugar and more mineral bitterness. Blackstrap molasses comes from the third boiling and contains the least sugar (about 45% sugars) with the strongest flavor and slightly lower density. Blackstrap may weigh closer to 310–320 g per cup. The 337 g/cup figure applies to light or medium molasses — the most common variety used in gingerbread, baked beans, and cookies.
Measuring molasses: the same mess problem as honey, same solution
Like honey, molasses is viscous and clings to everything it touches. A cup measured by volume invariably leaves a film behind that reduces your actual quantity. The same oil-coating trick (spray the cup or measuring spoon first) helps, but weighing directly into your mixing bowl is more reliable. At 337 g/cup, even small amounts of molasses are practical to weigh: ¼ cup is 84 g, 1 tablespoon is 21 g. In gingerbread recipes where molasses contributes its characteristic dark color and bittersweet depth, accuracy in quantity affects both flavor intensity and the moisture balance of the final product.
Frequently asked questions
- How many grams is ¼ cup of molasses?
- ¼ cup of molasses weighs about 84 g (337 g ÷ 4).
- Is molasses heavier or lighter than honey?
- About the same — molasses (337 g/cup) and honey (340 g/cup) are nearly identical in density, both significantly denser than water due to high sugar concentration.
- How many cups is 200 g of molasses?
- 200 g ÷ 337 g/cup ≈ 0.59 cups — about ½ cup + 1.5 tablespoons.
