In a saucepan over medium heat, combine water, sugar, salt, and 2 tablespoons of vegetable oil. Bring the mixture to a boil and remove from heat.

Stir in the flour until the mixture forms a ball of dough. Let it rest for a few minutes to cool slightly.

Heat oil for frying in a deep fryer or large, heavy pan to 375°F (190°C).

Transfer the dough to a piping bag fitted with a star tip.

Pipe strips of dough into the hot oil, cutting them with scissors or a knife. Fry until golden brown, turning occasionally to ensure even cooking.

Remove churros from the oil and drain on paper towels to absorb excess oil.

In a shallow dish, mix sugar and ground cinnamon for coating.

Roll the warm churros in the sugar-cinnamon mixture until evenly coated.

Serve churros warm with your favorite dipping sauce, such as chocolate or caramel.
