In a medium size saucepan over medium heat, combine water, sugar, salt and 4 tablespoon canola oil. Bring to a boil and remove from heat.
Stir in flour until a ball of dough forms. Let dough cool slightly so that you don't burn yourself when piping the churros.
Place dough in piping bag fitted with a metal tip.
To make the heart shape: pipe two strips of dough. Form them together to make a heart shape, ensuring to pinch the adjoining points together so that they stay together when frying.
Heat oil for frying in a deep skillet. Once oil is hot enough to fry, place heart churro on a large spatula (touch up the shape if needed). Place spatula with churro in oil. Once churro starts frying, it will be easy to remove the spatula.
Fry until churros are golden brown. Remove with spatula and drain on paper towel.
Repeat this process for all churros. Depending on the size of your pan, you will be able to fry multiple churros at once.
In a bowl or dish, combine sugar and cinnamon. Coat churros in mixture.
Serve with dipping sauces, and enjoy!
