Yellow cake, as the name suggests is yellow and it usually gets this color from the use of egg yolks. The white cakes are so called because of the fact that they use the whites of the egg rather than the yolk while baking the cake.

Like the rest of the cakes, these types of cakes also use substances like flour, baking soda, sugar, milk and vanilla. Yellow cakes are also recognized as Golden Cake, a Moist Yellow Cake and/or a Yellow Butter Cake. As stated before, it is not the yellow food coloring, but the natural yolks of the eggs which is capable of giving the cake such a rich vibrant color.
The concentration of the yellow color in the cake is totally dependent upon the baker as he/she is the only person who has the power to decide the amount of egg yolks to be added in the mixture of the cake to be prepared. There are some people who prefer to use four eggs. On the other hand, there are a number of people who do not like the smell of eggs and like their food with minimum eggs in it.
