In a large dutch oven, add enough canola oil to fill the pan about half way, heat it over medium heat to heat it to 375 degrees. You can also use a deep fryer for this.
Canola Oil
In a large saucepan, add the water, butter, vegetable oil, 1 Tbsp of sugar, vanilla and salt, bring to a boil. Turn the heat down to low and add the flour, stirring constantly until the mixture turns into a ball, cook this mixture for about 1 minute. (Remember to constantly stir)
1 cup All Purpose Flour, 3 Tbsp Unsalted Butter, 1 Tbsp Vegetable Oil, 1 Tbsp Granulated Sugar, ½ tsp Salt, 1 tsp Vanilla Extract, 1 cup Water
Add the dough into the bowl and add one egg a time and mixing well after each addition to make sure the egg is well combined.
4 Eggs
Spoon the dough into a piping bag fitted with a large star tip.
Pipe 5 inch ropes into the hot oil (be very careful) and make sure you only cook a few at a time so you don’t bring down the temperature of the oil. Cook them for a few minutes on each side or until deeply golden brown.
Drain them on paper towels to remove excess oil and repeat with your remaining dough until it is all used.
Dust the hot churros in the cinnamon sugar mix and serve hot.
1 Tsp Ground Cinnamon, ½ cup Granulated Sugar
