Replacing Cabinet Hardware?

I know it is really minor, but I just can't stand the fake brass handles on the cabinets and drawers. I got some replacements, but the originals aren't screwed on from the back like they would be in a house.

I'm wondering if anyone has removed them. If so, do they pop off somehow? I tried prying one off, but didn't want to ruin the cabinet in the process.

I was thinking this would be such an easy way to update the interior - just a couple of screws out and couple in and boom! But no...
