Melt the butter with water & sugar until it's melted and simmering

Put to low heat and add the flower until it's mixed (for around 3 minutes)

Flatten the dough in a bowl to cool for 10 minutes then add the egg one by one

Put the dough into a piping bag with a star-shaped tip

Cut the dough evenly and fry until golden

While waiting for the churros to cool let's make the chocolate dip

Melt the chocolate, sugar, and milk in medium heat until it's melted. (WARNING: keep on stirring so the mixture will not burn)

Mix the cornstarch with the water then add it to the chocolate mixture

Keep on stirring until the mixture thickens

While the churros are still hot cover them with the sugar and cinnamon

Enjoy!
