If you wanted to mix a cake batter in the morning and bake the cakes in the afternoon, then you should definitely not use __________ in your formula.

Question

Quizplus · Accepted Answer

Baking soda and single-acting baking powder both react and produce gas bubbles as soon as they are moistened. If you mix your batter in the morning and wait until the afternoon to bake, most of the gas will have escaped, leading to a denser cake. Double-acting baking powder, however, reacts in two phases, with the second phase activated by heat, making it suitable for recipes that aren't baked immediately.
