Help a newbie

I wanted to know if there is any plugin, which can help me create “Latest from the blog” section in my sidebar. A shortcode or something like that which I can paste in the text widget. Let me explain it properly, I have a blog and a business site. Both are on different domains and servers. I wanted a section in my business site sidebar to show latest posts from my blog. With title, 1 or 2 line from the post and a small thumbnail. I don’t know if I can do that or not, Any help will be highly appreciated. Thanks
