I enjoy baking cakes, but am not so great at the icing/decorating part.
Way back, cakes were only modifications of breads, it was easier to do it
So the sugary sweetness was added later?  Or just the shape was modified?
Both.In those days, cakes were only a different type of bread.
Well, I'm certainly glad they evolved to what they are today.  I just love birthday cakes.
 Cake is often served as a celebratory dish on ceremonial occasions, such as weddings, anniversaries, and birthdays
I think it should be served every day!  Why save it for the special occassions, every day should be one.
Making a cake is easier nowadays becausebaking equipment and directions have been simplified so that even the most amateur cook may bake a cake. 
That is very true.  My girls learned very easily how to do this - now they love baking as wel.
And if you are to busy to bake, just buy a cake
