Why Weigh Baking Powder in Grams?
When a recipe calls for 1½ cups of baking powder, using a kitchen scale to measure exactly 288 grams will give you far more consistent results than volume measurement alone. This is because baking powder can be packed, sifted, or scooped differently each time, leading to weight variations of up to 20%.
How to Measure Baking Powder by Weight
Place your mixing bowl on a digital kitchen scale and press "tare" to zero it out. Then add baking powder until the scale reads 288g. This method is faster than measuring cups and eliminates the guesswork entirely.
