Hey Joanna. First if all, a dozen means 12 so you you would say " two dozen eggs" because the word "dozen" works just like "hundred". When talking about specific numbers, we say "a hundred", "two hundred", "three hundred", etc. In the same way, we say "a dozen", "two dozen", "three dozen", etc. If we are talking about some unspecific large number, we can say "dozens of" or "hundreds of". For example: -Hundreds of children missed the first day of school because of the newspaper error. -The storm caused dozens of empty bottles to wash up on the beach.

Two dozen eggs. Dozen is a noun meaning "group of 12": one dozen, two dozen, three dozen. Egg is a countable noun so can be made plural in this context. It's the same as saying "24 eggs". You wouldn't say 24 of eggs :)

Two dozen eggs is correct. Additionally, one can also say two dozen cartons of eggs. Moreover, one can also say two dozen egg sandwiches. Furthermore, in English, it is also common to say two dozen egg yolks or two dozen egg whites.

Two dozen of eggs
