Important Considerations for Whole Wheat Flour:
The weight of 1 US cup of whole wheat flour is often considered similar to all-purpose flour, around **120-128 grams per cup** (approx. 4.25-4.5 ounces) when using the "spoon and level" method. However, it can vary based on the grind (fine vs. coarse) and how it's packed.
Some whole wheat flours, especially stone-ground or coarser varieties, might be slightly heavier by volume.
For reliable results in whole grain baking, **using a kitchen scale to measure flour by weight (grams or ounces) is highly recommended.**
