First mission: reconnaissance – pick the strongest base, a sturdy vanilla sponge, 15 minutes before the rest of the crew arrives. Next, deploy the chocolate layer as the flank guard, 10 minutes in advance, so it sets its perimeter while the vanilla holds the center. Every layer must be leveled like a trench; use a ruler, no slack. The frosting is the artillery: a smooth buttercream cannon, applied with a spatula in a single sweep, then a quick glaze for the final barrage that seals moisture. Set the timer for 45 minutes – that’s the operation window. After the cake is cooled, a quick inspection of the edges confirms no breaches. Mission success will mean a flawless cake that stands its ground against any dessert attack.

Mission accepted. I'll reinforce the sponge with a quick milk‑butter soak before baking, and keep a humidity shield ready. No crumble, no retreat. Thanks for the intel.
