Step 1: Prepare the Dough

1. In a saucepan over medium heat, combine water, butter, brown sugar, and salt.

2. Bring to a simmer.

3. Add flour all at once. Stir constantly until a soft, sticky dough forms and a starchy film appears on the bottom (about 5 minutes).

4. Continue cooking for 1 more minute, scraping up some of the film with your spoon.

Step 2: Cool and Incorporate Eggs

1. Transfer the dough to a bowl and let cool for 10 minutes.

2. Stir in vanilla extract.

3. Add eggs one at a time, mixing thoroughly after each. Dough may look separated initially, but will come together into a smooth, sticky texture.

Step 3: Prepare for Piping and Baking

1. Preheat oven to 425°F (220°C). Line two baking sheets with parchment paper or Silpat mats.

2. Fill a pastry bag fitted with a star tip (like #356) with dough.

3. Pipe 3–4 inch ropes, leaving space between each. Cut the ends with the back of a knife.

Step 4: Bake the Churros

1. Lightly spray tops of churros with vegetable oil and mist the pan with water.

2. Bake 20–25 minutes, until puffed and golden brown.

3. Turn off oven, open door briefly, then leave slightly ajar (8–12 inches). Let churros rest 10 minutes in the warm oven.

Step 5: Finish with Cinnamon Sugar

1. Mix sugar and cinnamon in a small bowl.

2. Toss warm churros in the mixture to coat evenly. Serve immediately.
