- Sign in to blogger.com.
- Next to the blog you want to delete, select Settings from the drop-down..
- Select Settings.
- Under “Settings” on the left side of the page, click Other.
- Go to “Blog tools.”
- Optional Click Export blog to save a copy on your hard drive.
- Click Delete this blog.
Blogger.com is a Google company/product so there is some cumbersome work and its not real easy but also not real hard.
