After its purpose has been completed, the brain golem goes back and is absorbed back inside its progenitor. So it's both a calzone golem kept in the freezer for later, a flesh golem for brain-composed creature, and the poor man's Magic Jar.
If it's a basic construct like other D&D golems, it's weird to make it out of either food or elder brain bits. If it's an avatar of the Elder Brain, it's weird to call it a golem. It feels like it's torn between a couple different ideas, one of which I would like, but it's dragged down by the Eldritch Snacks Golem part.
