Ground Cinnamon:
Grams to Cups
By Stefan Ulrich · Last updated
Ground cinnamon weighs 125 grams per cup, but it's almost always measured in teaspoons: 1 teaspoon = approximately 3 grams. It's one of the most frequently used baking spices, and the variety of cinnamon you use — Ceylon or cassia — can dramatically change the flavor of your recipe.

About Ground Cinnamon
Cassia cinnamon (the variety sold in most American supermarkets) is stronger, spicier, and more pungent. Ceylon cinnamon ('true' cinnamon) is subtler, more complex, and slightly floral. They weigh approximately the same per teaspoon, but their flavor intensity is very different — if a recipe was developed with cassia cinnamon and you substitute Ceylon, you may want to increase by 25–50%.
For spice cakes, cinnamon rolls, and snickerdoodles, cinnamon is used in quantities of 1–3 teaspoons (3–9 g). At these quantities, even a small measurement error is detectable. Level your teaspoons carefully — a heaping teaspoon of cinnamon can weigh 5–6 g, nearly double the flat measurement.
Cinnamon can also be used in surprisingly large quantities in certain applications: Mexican hot chocolate, Indian chai, and some Middle Eastern rice dishes use tablespoon quantities (7–8 g per tablespoon).
Ground cinnamon loses potency after 6 months. A quick freshness test: rub a pinch between your fingers. If the scent is faint or dusty, replace it. Fresh cinnamon smells warm and immediately aromatic.
Tips for measuring Ground Cinnamon
- 1 tsp = ~3 g. 1 tbsp = ~8 g. Always level your spoon.
- Ceylon vs. cassia: use 25–50% more Ceylon to match cassia's intensity.
- Ground cinnamon loses potency after 6 months — replace regularly.
- Store away from heat and light in an airtight jar.
Common mistakes
- Using heaping teaspoons — nearly doubles the actual amount
- Substituting Ceylon for cassia 1:1 — Ceylon is noticeably milder
