This is a pretty great replica of Portal 2's Space Core. The scale is good, the colours are right, the lighting looks spot on, and I bet it was delicious. Wait, what?
Yeah, spoilers, it's a cake. I know, sorry to go all "Kotaku circa 2007" on you, but come on. That's freaking amazing.
It was made by Mike's Amazing Cakes in Redmond, Washington, for sharkhats and offwithyourtv's wedding anniversary. You kids are both keepers.
