My search for this scene: https://umd.net/forums/looking-for-a-caking-scene-from-a-tv-sho was successful.

My thanks to Eggedme for helping me find it.

The scene is from the 2010 Austrian movie "Die unabsichtliche Entfuhrung der Frau Elfriede Ott", and the caked actress is Monica Reyes.
Here is the full video: [Link removed because Youtube video was marked as unlisted. We try to respect that.]

It's in German so I've added English subtitles.

There's a TV segment/behind the scenes/making of for this scene, but I wasn't able to find it.

Fantastic caking and wish we got to see a little more of her walking in public. So humiliating

but it doesn't show much.

Great.
I'm pretty sure there was something in addition with her talking, but maybe I'm wrong.
