Whipped egg whites are foam – the whites are a protein structure that traps a ton of air.

When the batter is cooked, the air expands making the cake rise. The protein structure stretches to accommodate this, so the air doesn’t escape.

As the cake cools, the protein structure stiffens back up, keeping the risen shape even as the air inside shrinks.
