Can dry yeast be used to make cakes?

No

"Dry yeast cannot be used to make cakes. Yeast is completely different from baking powder. Yeast It is a kind of organism that can only be used in bread. Yeast reproduces by being given sugar and suitable temperature, and spits out carbon dioxide to make the bread buns bigger. That is to say, the holes in the bread are caused by the yeast protruding and the carbon dioxide cannot escape and stay there. The result inside is that because the dough is very thick and hard, the oil content of the cake is too high, which is not suitable for yeast to survive.
