How to measure baking powder accurately
The 192 g figure assumes the spooned-and-levelled method: spoon the baking powder into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
- 1 US cup of baking powder = 192 g

- ¾ cup = 144 g
- ½ cup = 96 g
