I'm planning to make the cake batter from scratch on Sunday, refrigerate it (not freezing!) for about 3 days, and bake it up on Wednesday. But I'm cramped for time on that day.
I've researched that the cake wouldn't rise as high, and one of bizcocho dominicano's known qualities is to be light. This probably isn't relevant, but I'm turning the cake recipe into a cupcake recipe.
What if I make the batter and leave out the baking powder until Wednesday? Then I can put the powder in and mix the batter so it can become fluffy again. Do you think this'll work? Will it still rise?
