In a medium saucepan, combine 1 cup of water, 1 tablespoon of white sugar, 1/2 teaspoon of salt, and 1 tablespoon of vegetable oil. Bring this mixture to a boil over medium heat.
Once the water mixture is boiling, remove it from the heat and quickly stir in 1 cup of all-purpose flour. Mix until the dough forms a ball and pulls away from the sides of the pan.
Allow the dough to cool for about 5-10 minutes. This helps it become easier to handle and pipe.
While the dough is cooling, heat additional vegetable oil in a deep frying pan or pot. You’ll need enough oil to cover the churros while frying, about 2-3 inches deep. Heat the oil to 350°F (175°C).
Transfer the cooled dough to a pastry bag fitted with a large star tip. Carefully pipe strips of dough into the hot oil, cutting them to your desired length with scissors.
Fry the churros in batches, being careful not to overcrowd the pan. Cook for about 2-3 minutes on each side or until they turn golden brown. Use a slotted spoon to remove them and place them on paper towels to drain excess oil.
In a shallow dish, mix 1/2 cup of white sugar with 1 tablespoon of ground cinnamon. Roll each churro in this mixture while they are still warm, ensuring they are fully coated.
Serve your warm churros with chocolate frosting or chocolate hazelnut spread for dipping. Enjoy the delightful contrast of crispy churros and creamy chocolate!
