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 the mixture to a boil over medium heat. Once it reaches a boil, remove it from the heat and stir in 1 cup of all-purpose flour until a smooth dough forms.
Allow the dough to cool for about 10 minutes. This will make it easier to handle when piping.
In a deep frying pan or pot, heat about 2 inches of vegetable oil over medium heat. Ensure the oil is hot enough for frying by testing it with a small piece of dough; it should sizzle and rise to the surface.
Transfer the cooled dough into a piping bag fitted with a star tip. Once the oil is ready, carefully pipe strips of dough directly into the hot oil, cutting them to your desired length.
Fry the churros until they are golden brown and crispy, which usually takes about 2-3 minutes. Use tongs to turn them occasionally, ensuring even cooking.
In a shallow bowl, mix together 1/2 cup of white sugar and 1 tablespoon of ground cinnamon. Once the churros are cooked, remove them from the oil and drain them on a wire rack. While they are still warm, roll them in the cinnamon sugar mixture to coat.
Serve the churros warm with a side of chocolate frosting or chocolate hazelnut spread for dipping. Enjoy the delightful combination of flavors!
