1-First Step: Prepare Ingredients and Equipment
Gather all necessary ingredients: 1 1/2 cups (180 g) all-purpose flour, 1 cup (240 ml) water, 1/2 cup (115 g) butter, 4 large eggs, 1 teaspoon vanilla extract, and 1/2 teaspoon salt. For the coating, have 1/2 cup (100 g) sugar and 2 teaspoons ground cinnamon ready. Set up a deep pan or fryer with vegetable oil and heat it to between 325°F and 350°F (160°C to 175°C). Prepare a large piping bag fitted with a star-shaped nozzle like a churrera or a large star piping tip. Having a thermometer helps maintain the correct frying temperature.

2-Second Step: Make the Dough
In a medium saucepan, combine water, butter, vanilla extract, and salt. Bring to a boil over medium heat until the butter melts completely. Remove from heat and immediately stir in the all-purpose flour until the mixture forms a thick dough that pulls away from the sides of the pan. Allow the dough to cool for 5 to 10 minutes before adding eggs.

3-Third Step: Incorporate Eggs Gradually
Add the eggs one at a time, beating well after each addition to achieve a smooth, homogenous dough. The dough should be thick but pipeable. Using a mixer or wooden spoon can facilitate this process. This gradual addition ensures the churro churro dough achieves the right elasticity for frying and shaping.

4-Fourth Step: Pipe and Fry the Churro churro
Fill the prepared piping bag with dough. Carefully pipe the dough into the hot oil, cutting pieces at your desired length usually around 5 to 6 inches (12 to 15 cm). To avoid oil splashing, pipe close to the oil surface and use scissors to cut the dough. Fry pieces in batches, not overcrowding the pan, for about 1 to 3 minutes until golden brown and crisp. Adjust frying time depending on the churro churro size and oil temperature. Use a slotted spoon or spider skimmer for safe handling.

5-Fifth Step: Drain and Coat
Remove churro churro from oil and place on paper towels to drain excess oil. While still warm, roll them immediately in the prepared cinnamon sugar mixture. This coating gives the churro churro its classic flavor and adds a sweet, slightly crunchy exterior.

6-Final Step: Prepare and Serve with Chocolate Ganache
For the traditional accompaniment, heat 1/2 cup (120 ml) heavy cream just until simmering. Pour over 4 ounces (113 g) of semi-sweet or bittersweet chocolate chips in a bowl. Whisk until smooth to create a thick chocolate ganache for dipping. Serve churro churro hot to preserve the signature crispness and soft interior.
