Cream the butter and ½ cup sugar together until it’s light. Drop in egg yolks one by one, then mix in the vanilla and melted chocolate.

Whisk the egg whites and salt until they’re foamy and soft peaks appear. Gradually add the rest of the sugar and beat until it stiffens.

Mix the whipped egg whites into the chocolate mixture in thirds. Alternate with the flour to make sure the batter stays airy.

Pour batter into the pan and bake for around 45-50 minutes. Check with a toothpick; if it comes out clean, it’s done.

Let the cake sit in the pan for 10 minutes. Then, remove the sides and cool completely before moving on.
