Cacher is the code snippet organizer for pro developers

At the end of your Blogger post , using HTML editor, append this

<script src="https://raw.github.com/moski/gist-Blogger/master/public/gistLoader.js" type="text/javascript"></script>

In the content of your blog post, simply add this:

<div class="gistLoad" data-id="8488564" id="gist-8488564">Loading https://gist.github.com/8488564....</div>

Note: adding the URL is useful because when the javascript does not work, readers can copy and paste the URL themselves. 

If you need to specify a single file within a Gist, use the data-file attribute
<div class="gistLoad" data-id="4982341" data-file="gistfile2.cs" id="gist-4982341">Loading https://gist.github.com/4982341....</div><br />
