There are lots of ways to be creative with a blog post. Not every post needs to be a step-by-step tutorial (although those are great too).

• A reaction to another blog post
• You could carefully read a spec and talk about what you learned
• A little thing you learned today
• A hot take on some news
• Something that you don't know about but wish you did
• A super long in depth tutorial
• A explanation of an app you’d buy if it existed
• A transcript of a real conversation
• A transcript of a fake conversation
• You explaining some weird life quirk you have
• A recipe
• A series where you dig up very old articles to comment on
• A book review as told from a character in the book
• A to Z
• A complex answer to a simple question
• A simple answer to a complex question
• An open letter
• An interview with someone interesting
