First, heat the water and add the butter and salt. When the water is boiling and the butter has completely melted, add the flour all at once and remove from heat.

Then stir until the flour is fully incorporated and add the eggs.

Next, add the cinnamon and mix until everything is well combined, then place the mixture in the piping bag or churro maker.

Heat oil in a pan and start adding the churros.

Finally, remove them from the oil when they are golden brown, let them cool slightly, sprinkle with sugar, and they're ready.
