One of life's greatest mysteries has finally been revealed ... what makes Kanye West happy -- and we got the photo evidence to prove it.

Kanye hit up Baskin Robbins in West Hollywood Thursday (pictured above) donning his usual unhappy gaze ... but moments later, a true Christmas miracle occurred.

As shocking as it sounds -- a look of pure joy spread across Kanye's face just seconds after licking the cone ... something that hasn't been seen in ages.

So paparazzi take note -- better start carrying around a cooler.
