The baking of cake by mother is an example of chemical reaction.
First of all, let us see what does a chemical reaction mean.
A chemical reaction is a type of reaction involving one or more substances as reactants as they are converted to one or more substances called products.
In the chemical reaction, the molecules and atoms of the reactants are changed completely to form products.
It is irreversible, the original substance formed cannot be recovered.
Similarly, when we make a cake from flour, sugar, egg, water, etc all these are the reactants and the final cake formed is the product.
The cake formed can never be transformed back to the ingredients (flour, sugar, egg, water, etc.)
So, the baking of cake is a chemical reaction.
