Cornmeal:
Grams to Cups
By Stefan Ulrich · Last updated
One cup of cornmeal weighs 140 grams. This coarsely or finely ground dried corn is the essential ingredient in cornbread, corn muffins, and polenta, providing a slightly sweet, earthy corn flavor and a satisfying, slightly gritty texture.

About Cornmeal
Cornmeal comes in fine, medium, and coarse grinds, which affect texture more than weight. Fine-ground cornmeal (closer to corn flour) yields a smoother, more cake-like crumb in cornbread. Coarse-ground cornmeal produces a heartier, more rustic texture. Both weigh approximately 140 g per cup.
Stone-ground cornmeal retains the corn's germ and bran, giving it more flavor and nutrition but also a shorter shelf life due to the natural oils in the germ. Degermed commercial cornmeal is more shelf-stable but less flavorful. For Southern-style cornbread, stone-ground cornmeal is the traditional choice.
In baking, cornmeal adds structure as well as flavor. In cornbread specifically, it absorbs liquid and expands during baking, giving the finished bread its characteristic slight denseness. For a more tender crumb, some recipes soak the cornmeal in the liquid ingredients first (a technique called scaldling) to pre-hydrate the grains.
When cornmeal is used to dust baking surfaces — pizza peels, baking sheets for bread — use it sparingly. Its primary function here is to prevent sticking through physical separation, not through fat, so a thin, even layer is all that's needed.
Tips for measuring Cornmeal
- Use the grind the recipe specifies — coarse and fine cornmeal produce different textures.
- Soak in buttermilk or milk for 30 minutes to pre-hydrate and soften the grains.
- Stone-ground cornmeal: store in the fridge or freezer to prevent rancidity.
- Spoon into the measuring cup — cornmeal can pack quite densely when scooped.
Common mistakes
- Substituting corn flour (very fine) for coarse cornmeal without adjusting texture expectations.
- Storing stone-ground cornmeal at room temperature — the germ causes rapid rancidity.
- Scooping directly from the bag, which compacts and overestimates the quantity.
Frequently Asked Questions
- How many grams in a cup of Cornmeal?
- 1 cup of Cornmeal weighs 140 grams — the standard used in most American recipes. Use the converter above for any other amount.
- How many grams is ¼ cup of Cornmeal?
- ¼ cup of Cornmeal weighs about 35 grams. The full table above lists every common cup fraction.
- What's the most common mistake when measuring Cornmeal?
- Substituting corn flour (very fine) for coarse cornmeal without adjusting texture expectations. Weighing on a kitchen scale avoids it entirely.
- Should Cornmeal be measured cooked or dry?
- These values are for dry, uncooked cornmeal. Cooked weights differ greatly because of absorbed water.
