Crispy, golden churros coated in cinnamon sugar and served with chocolate dipping sauce are an irresistible family treat. This beloved fried pastry brings carnival excitement to your kitchen.
In a medium saucepan, combine water, unsalted butter, and salt. Bring to a rolling boil over medium heat, stirring to melt butter completely.
Reduce heat to low. Add all-purpose flour and stir vigorously with a wooden spoon until the mixture forms a cohesive dough ball, pulling away cleanly from the sides (about 1–2 minutes).
Remove dough from heat and let it cool for 5 minutes. Then beat in the large egg fully until the batter is smooth and shiny.
Transfer dough to a piping bag fitted with a large star tip. In a deep pot, heat vegetable oil to 350°F (medium-high heat; use a thermometer for accuracy).
Pipe strips of dough (about 5 inches) directly into the hot oil, frying 3–4 at a time. Fry, turning occasionally, until golden and crisp (about 2–3 minutes per side). Remove and drain on paper towels.
While still warm, toss churros in a mixture of sugar and ground cinnamon, ensuring even coating.
For dipping sauce, gently heat heavy cream until steaming (not boiling) and pour over semisweet chocolate chips. Let sit 1 minute, then stir until smooth. Serve warm with churros.
