Add butter, milk, and salt to a saucepan over medium heat. Stir and add flour to the saucepan when the milk starts to boil. Don’t remove the pan from the heat until the mixture is thick and smooth. Make sure you are left with a consistent dough when you remove the pan from the heat.

Now, add eggs one at a time to the pan and mix them well. Before adding another egg, let this egg completely incorporate into the mixture. Once its done, transfer the dough into a pastry bag and make small balls from it on the greased baking tray.

Bake these profiteroles in a preheated oven (210 C) for about 15 to 20 minutes and then, let them cool. Open the profiteroles in half and add whipped cream using a pastry bag and then close the profiteroles again.

For chocolate sauce, place a saucepan in the water bath and add chocolate along with milk to it. Stir thoroughly until the chocolate melts to form a smooth chocolate sauce. Drizzle this sauce over the profiteroles and serve.
