Creating California Churros Churro Sandwich can be a delightful experience when you follow these simple steps:

1. Prepare the Dough: In a medium saucepan, combine water, unsalted butter, granulated sugar, and salt. Bring to a boil over medium heat.
2. Add Flour: Once boiling, remove from heat and stir in the flour until the mixture forms a ball.
3. Cool Slightly: Allow the dough to cool for about 10 minutes.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until smooth.
5. Heat Oil: In a deep skillet, heat oil over medium-high heat for frying.
6. Pipe the Churros: Transfer the dough to a piping bag fitted with a star tip. Pipe 6-inch strips of dough into the hot oil, cutting them with scissors.
7. Fry Until Golden: Fry the churros for about 2-3 minutes on each side until golden brown. Remove and drain on paper towels.
8. Coat with Sugar: In a shallow dish, mix granulated sugar and cinnamon. Roll the warm churros in this mixture until fully coated.
9. Prepare the Filling: In a mixing bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.
10. Assemble the Sandwiches: Slice churros in half lengthwise, fill with whipped cream, and close to form a sandwich.
