Add a “back to blog link” to single.php Pagination

I am looking to add a button in the middle of the pagination on my single-post page that will allow the reader to easily get back to the beginning of the blog with one click. I currently have next and previous post. You can view a sample page here.

The code I presently have added to the single.php is:

<div class="pagination clearfix">
    <p class="pagination-next">
         <?php previous_post_link('%link', '< Previous Entry'); ?>
    </p>
    <p class="pagination-prev">
         <?php next_post_link('%link', 'Next Entry >'); ?>
    </p>
</div>
