the purpose of baking powder in a cake is to make it rise and not make it flat and if you put too much of baking powder your cake might burst in the oven/microwave what ever you use
depending on recipe but in general 1-2 tsp.
no just don't use too much
You probably could; it may make your cake rise a little more. I wouldn't add much, no more than 1/2 to 1 teaspoon. But you really should not need to add baking powder, as there should be enough in the cake mix.
Yes, 4 teaspoons of baking powder is generally considered a lot for a cake. Most cake recipes typically call for about 1 to 2 teaspoons of baking powder per cup of flour. Using too much can result in a cake that rises excessively and then collapses, leading to an undesirable texture and taste.
One reason a cake was overflow/ burst/ explode is that too much baking powder has been added :)
You cannot use baking powder as a substitute for baking soda.
The amount of baking powder required depends entirely on what you intend to bake. Different types of cookies, muffins and other baked goods require different proportions of baking powder to flour.
You replace a cake mix by making the cake from scratch. Any cake recipe from a cook book or found online will tell you how much flour, sugar, baking powder or baking soda, salt and other ingredients to use.
It will rise too much and probably over flow. Too much baking powder will cause the cake to rise rapidly and then collapse, as well as giving the cake a bitter taste. The finished cake will have a fallen center, and a course crumb,
What do you think?
A cake made with baking soda can rise more than a cake made without it because baking soda reacts with acid in the recipe to produce carbon dioxide gas, which creates bubbles in the batter, causing it to rise. On the other hand, a cake without baking soda may rely on other leavening agents like baking powder or beaten eggs to rise, but it may not rise as much as a cake with baking soda.
