WordPress.org

In the WordPress Dashboard, in the upper right corner, one must open and hover through a dropdown menu to logout, which in the minds of some is equivalent to two clicks of a mouse. TWO CLICKS! To enhance the ease of use, this simple plugin alters the logout to occur with a single click.

Generally:

No more maneuvering through annoying dropdown menus.

One click and you're out!!!!

Features:

• Creates a simple one click logout for the WordPress Dashboard.
• Simplifies and drops user profile link.

For one click logout but without the admin bar, remove it using the Admin Bar Removal plugin by sLa, in conjunction with a forked version of this plugin: One Click Logout Barless, thus restoring a WP 3.2-like header AND one click logout. Or try a fusion of them with ToolBar Removal. With all of the above, one click and you're out.
