The easiest way to delete a post in Google Blogger is to go to your dashboard.
From there, select "Edit Posts". In the next page, you will have a list of your posts and way over on the right is the word "Delete". Click on that, Google Blogger will ask you if you're sure, and it goes away. By the way, if that is the only post you have in that particular category (label), that category (label) will go away, too.
