The expression "have your cake and eat it, too" doesn't make logical sense because once you eat your cake you can no longer possess it in cake form because you've eaten it. Paul Brians, Professor of English at Washington State University, points out that perhaps a more logical or easier to understand version of this saying is: “You can’t eat your cake and have it too”. Professor Brians writes that a common source of confusion about this idiom stems from the verb to have which in this case indicates that once eaten, keeping possession of the cake is no longer possible, seeing that it is in your stomach (and no longer exists as a cake). Alternatively, the two verbs can be understood to represent a sequence of actions, so one can indeed "have" one's cake and then "eat" it. Consequently, the literal meaning of the reversed idiom doesn't match the metaphorical meaning.
