Churros are a popular Mexican dessert that are crispy on the outside and soft on the inside. They are made from a simple dough that is piped through a star-shaped nozzle, deep-fried until golden brown, and coated in cinnamon sugar. Churros are often enjoyed with a cup of hot chocolate or dulce de leche for dipping. To make churros, combine water, butter, sugar, and salt in a saucepan and bring to a boil. Remove from heat and stir in flour until a smooth dough forms. Transfer the dough to a piping bag fitted with a star-shaped nozzle and pipe it into hot oil. Fry until golden brown, then roll the churros in cinnamon sugar. Serve the churros warm and enjoy!
