ELI5, how does stirring something hot like hot chocolate cool it down?

People have said that it brings up warmer hot chocolate from the bottom of the mug, but why isn’t the entirety of the hot chocolate the same temperature?

The top of the chocolate cools down from the air, so it’s colder than the bottom. Stirring it brings up the hotter chocolate up from the bottom. Then hot chocolate at the top cools down faster than cold chocolate at the top would.
