You will eat hard, flat, possibly tasty cookies. Baking soda helps the cookies rise. Without it, they stay flat, as does matzoh.
It might make what you are making a little more dry... I use less butter when I make cookies and they turn out just fine...
The buns may turn out less rich and flavorful without butter. Butter also contributes to the texture and tenderness of the buns, so they may be drier and denser than intended. You could potentially substitute with another fat like oil or shortening, but the taste and texture may be slightly different.
Your cake would not rise. Or your cookies would not spread. Probably a Denser cake, or tougher cookie would be the case in those two instances..
Without yeast, dough would not rise or bake properly.
You will have frozen butter
No. Baking a cake involves chemical reactions between the ingredients. The fats in the butter are intended to interact in certain ways with the other ingredients - and this won't happen with apple sauce. This is not to say that the end result would be inedible - it might be - but it won't be a fruit cake.

Putting baking soda in your vagina can disrupt the natural pH balance, leading to irritation, inflammation, and potentially increasing the risk of developing infections. It is not recommended to use baking soda or any other home remedy internally without consulting a healthcare professional.
