FAQ
- Does sifting Whey protein powder change the cup weight?
- Yes — sifted Whey protein powder is lighter per cup because of added air. The table uses unsifted values; reduce by 15–20 % for sifted recipes.
- Is it safe to swap Whey protein powder for a similar powder at the same gram weight?
- For structure/mass yes, but leavening strength varies — baking powder is ~3× weaker than baking soda at equal mass. Check the chemistry, not just the weight.
