Combine water, butter, salt, and ¼ teaspoon of cinnamon in medium size saucepan over medium heat. Bring to rolling boil.
Once boiling, reduce heat to low. Add flour and stir vigorously until mixture forms a ball of dough. Remove from heat and let cool for 5-7 min.
Add eggs to the dough, one at a time, and stir until fully combined. Set aside.
Heat oil in medium skillet or 1-quart saucepan over medium-high heat or until temperature reaches 350˚.
Spoon the dough into a piping bag fitted with large star tip. Pipe 1-inch strip of dough over saucepan, cut with knife, and drop into hot oil. Repeat until churro bites fill saucepan with room to fry.
Fry churros until golden brown. Remove with slotted spoon or mesh strainer and place churro bites on paper towel.
Mix sugar and ½ teaspoon cinnamon in medium bowl. Toss in churro bites until coated. Place on serving plate and serve with favorite dipping sauce.

Notes
Prep the cinnamon sugar ahead of time so you can dust the fried churros right away after frying. The cinnamon sugar will stick better if the churro bites are still hot.
If you do not have a piping bag, you can substitute a ziploc style plastic bag. Spoon dough into the bag and cut a hole in one corner. Squeeze the dough from the bag into the hot oil as directed.
Keep a close eye on the churros as they fry! If they begin to brown on the outside immediately or begin to turn black, your oil is probably too hot. Depending on your stove, you may have to adjust the heat settings a few times to keep it consistent.
