This is so easy! All you need is a credit card and it will cost you $10/per year to grab your own domain name for your blog.
Go to:
Your blog Dashboard
Settings
Publishing
Custom domain
Type in your desired domain
Check availability
If available click Continue to registration
Then the rest should be easy to follow through. You’ll want to make sure you tick the box “automatically renew each year”.
Let me know if you get stuck!
