YOU SAID:
I can have my cake and eat it too
INTO JAPANESE
私は私のケーキを持って、あまりにもそれを食べることができます
BACK INTO ENGLISH
I have my cake and can eat it too
INTO JAPANESE
私は私のケーキを持っていて、それも食べることができます
BACK INTO ENGLISH
I have my cake and it can eat too
INTO JAPANESE
私は私のケーキを持っていて、それはあまりにも食べることができます
BACK INTO ENGLISH
I have my cake and it can eat too
That didn't even make that much sense in English.
