Midway through the baking cycle at the twenty-minute mark, pulling the pan from the oven to deliberately drop it against the counter alters the final structure completely by forcing trapped air out of the puffed center. Achieving the right density relies entirely on this mid-bake deflation technique because standard visual cues fail completely when dealing with dark, high-fat batters that refuse to show traditional golden edges or clean toothpick tests. Over-baking destroys the desired fudgy mouthfeel, turning dense chocolate squares into dry cake, yet under-baking leaves an unstable puddle that never sets properly even after cooling. Whisking the eggs and sugars on high until they become remarkably light and fluffy introduces the necessary structural foundation, while the addition of cornstarch provides a tender chew that mimics classic boxed treats without relying on mysterious chemical powders. Melt the bittersweet chocolate, milk chocolate, and butter gently over simmering water, ensuring the bowl base never makes direct contact with the liquid so the dairy solids do not scorch or separate. Cool the baked pan entirely before attempting to portion the squares, then slice downward in one single motion with a long chef knife wiped clean with a damp paper towel between cuts to prevent ragged, crumbly edges.
