Baking powder ( NaHCO3) contains CO2 (carbon dioxide). Single Acting baking powder releases the gas when it gets wet. Double acting releases both when wet and when heated. When baking cake, the bubbles begin to form when making the batter and continue to expand as the cake batter bakes.
I am not quit sure that is true.
yeast
make the cake rise
It either helps whatever you're baking rise or make whatever you're baking soft and fluffy.
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
yes you can
no sour cream won't make a cake rise. i am 9 and still a food expert.
Yes because yeast is added to make the cake rise.
yes without flour the cake wont rise.
Baking powder is not a gas, but it does make a cake rise by releasing carbon dioxide into the batter through chemical reaction.
you can't really because the leavening agents or ingredients that make the cake mix rise will not work.
Particle vishmics make the cake flat and firey POO makes the cake brown and red and hats are brown, ALWAYS BROWN (thank poo for that)
No. The eggs don't make cakes rise. It is the baking powder in the cake flour.
