How can I Restore AKURUM cabinets that were painted back to their original finish?

Moved into a house a couple years ago. Previous owners painted the cabinets gray. Most of the cabinet doors were only painted on the outside so I can see the original black finish. I'd like to try and remove the paint because it's chipping easily and I don't think any real prep work (like sanding) was done.

Hoping I can avoid painting all the cabinets again if it's possible to resurrect the original color.
