Step 1: Make the Churro Dough
In a saucepan, bring the water, butter, sugar, and salt to a boil. Once it boils, remove the pan from the heat and add the flour all at once. Stir vigorously until the mixture forms a dough that pulls away from the sides of the pan. Let the dough cool for a few minutes, then add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Step 2: Fry the Churros
Heat the oil in a large pan or deep fryer to 350°F (180°C). You can test if the oil is ready by dropping in a small piece of dough — if it rises to the surface and bubbles, it’s good to go. Using a piping bag with a large star tip, pipe 4-inch long strips of dough directly into the hot oil. Fry the churros for 3-4 minutes until golden brown and crispy. Remove them and drain on paper towels.

Step 3: Coat the Churros
Mix sugar and cinnamon in a bowl. While the churros are still warm, roll them in the cinnamon-sugar mixture to coat them evenly.

Step 4: Make the Chocolate Sauce
In a small saucepan, heat the heavy cream over low heat, being careful not to let it boil. Once it’s warm, remove from the heat and add the chopped chocolate. Stir until smooth and glossy. If you prefer a sweeter sauce, add a tablespoon of sugar and mix until dissolved.

Step 5: Serve and Enjoy
Serve the churros warm, alongside the chocolate sauce for dipping. Enjoy the crispy, sweet churros with that rich, creamy chocolate sauce — total dessert bliss!
