Markdown syntax inside Jekyll Liquid results in plaintext rendering

I'm trying to list my posts like so, using Jekyll's Liquid:

{% for post in site.posts %}    - [ {{ post.title }} ]( {{ post.url }} ){% endfor %}

As far as I understand it, this should produce markdown similar to:

• Example Website

However, it simply substitutes the URL and title but returns plaintext:

- [Example Website](http://example.com)
