For the churros, bring butter, water and powdered sugar to a boil in a saucepan. Once the mixture is liquid, add flour and stir with a wooden spoon until the dough separates from the side of the pot.
Remove saucepan from heat and carefully stir in eggs, one at a time. Heat oil and pour choux pastry into a piping bag. Drop about 3 cm long strips of dough into hot fat.
Fry the churros for about 2 minutes until golden brown all over. Remove from the oil and drain on a paper towel. Sprinkle the churros with granulated sugar and serve.
Preparation Tip:
Serve with chocolate sauce and/or vanilla ice cream.
