Combine water, salt with the butter in a saucepan. Bring to a boil over high heat. Using a wooden spoon, stir in flour. Reduce the heat to low and stir vigorously until the mixture forms a ball, about 1 minute. Remove the dough from the heat and, while stirring constantly, gradually beat the eggs into the dough.

Turn the heat to low and continuously stir until the mixture forms a ball, about 1 minute.

Spoon the dough into a large, coated piping bag fitted with a Ateco star in size 4.
Mix extra sugar and cinnamon on a plate and set aside.
Heat 3 inches of vegetable oil or canola oil in a medium saucepan. Slowly, let the oil reach to 360 degrees before frying.
Place a large sheet of parchment paper near the range (so you don't have to walk far when frying) and squeeze the dough on the parchment paper to make, tightly round swirls.
When making them, pipe the dough close together to create the circle so it will stay intact when fried.
With a little flour and a spatula I was able to easily remove them from the parchment paper and into the oil.
Fry for about 1-2 minutes on each side.
Transfer the churros to a plate lined with paper towels to drain.
When they're cool, roll them in the extra cinnamon and sugar on the plate.
