Place a bowl of dark chocolate in a pot of hot water, add butter, and melt. When completely melted, put the bowl down, put the bowl with eggs in the pot, add brown sugar, salt, and vanilla extract, and whip.
When it becomes a fine foam, lower the bowl and add melted chocolate and butter and mix. Sift the flour and cocoa powder, mix well, and pour into the oven pan.
Put it in the refrigerator for a while.
