In a small bowl, stir together sugar and cinnamon; set aside.

Combine 1 cup water, olive oil, and salt in a medium pot and bring to a boil. Remove from heat. Stir in flour, stirring vigorously with a wooden spoon until combined and mixture forms a ball. Let cool slightly and transfer to a pastry bag with a large star tip*.

Heat 2-inches oil in a large sauté pan over medium-high heat.  Pipe 2-inch long lines of dough into the oil, cutting with a knife at the end. If bag is too warm, wrap with a kitchen towel. Dough will be stiff, so use force to squeeze out churros. Fry until golden brown, about 2 to 3 minutes. Remove from oil with a slotted spoon, and drain on a paper towel lined cookie sheet. Toss churros in cinnamon sugar and serve warm.
