Baking Powder: How Many Grams in a Cup?

Baking powder is a complete leavening agent (acid + base). Measuring by teaspoon is standard, but for scaling up recipes, weight is crucial. Excess baking powder causes cakes to rise rapidly and then collapse, leaving a bitter, metallic aftertaste. Precision prevents chemical disasters.

FAQ

Is it the same as Baking Soda?
No! Baking Powder contains acid. Baking Soda needs you to add acid (like lemon or buttermilk). Swapping them 1:1 will ruin the recipe.
