In a medium saucepan, combine water, butter, salt, and 1 tablespoon of sugar. Heat over medium heat until the mixture boils, and the butter melts completely.

Remove the saucepan from heat and quickly add the flour. Stir vigorously until a dough forms and pulls away from the sides of the saucepan. Let it cool for about 5 minutes.

Once cooled, add the eggs one at a time, mixing well after each addition until the dough is smooth and glossy.

Heat vegetable oil in a deep frying pan over medium-high heat until it reaches 350°F (175°C).

Use a piping bag fitted with a star tip to pipe small bite-sized pieces of dough into the hot oil. Fry them for about 2-3 minutes, or until they are golden brown.

Remove the churro bites from the oil and let them drain on paper towels.

In a bowl, mix together the granulated sugar and ground cinnamon. Roll the warm churro bites in the cinnamon sugar mixture to coat evenly.
