Hi,
I have been trying to do this for like 2 weeks. There was the old setting where you have to click "expand the widget templates". I seriously cant find it. No wonder la. Blogger already change its ,setting layout. Here's the new tutorial for 2014. I dont know if they're gonna change it again.

Steps:
1) These 3 different layouts that you may choose here:

https://developers.facebook.com/docs/plugins/like-button

2) Then copy the code by, get code> Iframe

3) Now to add the faceboook like button to all your blog post.
Log in to your blogger account , find dashboard > design > edit HTML

4) Use (ctrl + F), and find the code below:

<data:post.body/>

5)There might be two or more. Paste below the second . If it doesn't work,then try to paste after the first one.

6)Then don't forget to save template. Then view.

Give me a feedback if it works or not. 

Peace out
