sweets

I ate many cakes today. such as waffle, cookies.. and so on.

I had too many "cakes" today, such as waffles, cookies and so on.  I called desserts as cakes since I was very young.  Recently women in their 30's uses the word, "sweets" to mean cakes because the name sounds pretty and they want to be seen as fashionable.  In Japan, these women are known as "sweets".

To say "sweets" is a bit embarassing to me.

In America, sweets are known as candy.  In England, candy is called sweets.  Dessert mean something that is sweet tasting usually taken after a meal in the west.

I have called some cakes "Dessert" since I was very young.
but recently, women in their 30's call cakes "sweets", because the name sounds pretty and they want to be seem riding in the fashion.
Those women are called 'sweets' in Japan.

To say "sweets" is even a little embarrassing for me.

Note: I cut out the word "cakes" from the first two sentences because it seemed to me that you were talking about "sweets" and not "cake/cakes". I didn't cut it from the 3rd sentence because it wouldn't make sense. Let me know if my assumption was wrong, I will do a correction accordingly.
