Adding Buy Button to Blog Post

Is it possible to add a buy button to a blog post that features a specific product? Can it be added to a blog post with a shortcode perhaps (so that it’s easily do-able by the client)?

We’ll publish a blog post about a product, add some videos, images and text, and then include a buy button. The buy button should add the specific product to the cart.

If it isn’t possible at all, what do you recommend doing? Thanks for your help.
