What is the importance of flour in a cake?

Question

i wanted to know what the importance of flour in a cake was. What happens if you dont put any flour in a cake? What happens if you put double the amount?

Answer 1

The flour in a cake is basically the cake itself.  It is the grain that makes up the body and consistency of cake.  Basically without flour in a cake you would end up with a flat hard disk of melted sugar and other ingredients.  

Scientifically, the wheat glutens in flour are the little molecules that act with the leavening agent (baking powder/baking soda/etc.) that make the cake rise.  Without those protein chains in the flour, there is no cake.  Conversely if you added too much flour the wheat glutens can not be saturated with the liquids in the cake batter and will not allow the chemical reaction to happen that creates cake.  

Answer 2

it is the glue that binds the cake together and gives it volume. if you put no flour in a cake mix, it will be very sticky and concentrated. if you put double the amount, it will most likely not bake properly and you probably would not get a "cake" type substance but more like a dough.
