Hello,
By creating blog posts on the content your trying to rank for is a very smart move, actually, if it is done right. When your writing a blog post on Vanilla Ice Cream, every time you write about a page that relates on other content on your website, for example, if you mentioned ice cream, place a link there to your ice cream page. Also, with blogs, a very powerful tool is to have a "related posts" section, not only does this help build an internal linking structure, it also can interest readers to read other articles or content on your website.
Remember not to go overboard with focusing on keywords, you need to make sure that your website is friendly to the readers. If you are forcing yourself to change the structure of the content to change the keywords your optimizing for, it may lose it's readability. Google, along with many other search engines have put a lot of time into semantic cues, so they may infer that even though your not using the same keyword (something like Popsicle instead of ice pop), they can infer that your referring to the same thing.
My recommendation is to place a link on the blog post to the page you want to rank, and you should be okay,
Hope this helps
Zach
