Step 1

Heat water, salt, sugar, and butter in a saucepan over medium heat until the mixture begins to simmer.

Step 2

Add the flour and stir vigorously until a thick dough forms. Continue mixing until the dough pulls away from the sides of the pan and becomes smooth.

Step 3

Allow the dough to cool slightly. Mix in the egg and vanilla extract if using for extra richness and flavor.

Step 4

Transfer the dough into a piping bag fitted with a large star-shaped nozzle. This creates the classic ridged churro texture.

Step 5

Heat vegetable oil in a deep pan or fryer to 350°F (175°C). Carefully pipe strips of dough directly into the hot oil.

Step 6

Fry the churros for 2–4 minutes per side or until golden brown and crispy. Remove them with a slotted spoon and place them on paper towels.

Step 7

While still warm, roll the churros in cinnamon sugar until fully coated.

Step 8

Serve immediately with warm chocolate sauce, caramel, dulce de leche, or your favorite dipping sauce.
