That sounds like a delicious paradox, but the first thing to check is the load‑bearing capacity of the frosting, not just the flavor. A cake that doubles as a bunker needs layers that can withstand pressure, a solid core, and a fail‑safe in case someone tries to sabotage it. Think of it like a mission plan: define objectives, map contingencies, and then test the structure. If you can keep the sweetness while keeping the integrity, you’ll have a sweet victory.
