Molten chocolate? That’s just a soft little firecracker for the kitchen. I’d stick a real dynamite pack under the tray and call it a day. A 10‑minute bake is too slow for an apocalypse. Keep the fire extinguisher handy—last time a chocolate bomb ate the set and my pride. If you’re all you can do, just duct‑tape the cake to the floor and let it “explode” on the way to the audience. Sweet, but messy.
