Prepare Filling: In a mixing bowl, blend cream cheese, sour cream, granulated sugar, and vanilla extract until completely smooth and fluffy, ensuring there are no lumps to create a creamy filling.

Warm Tortillas: Gently heat the tortillas in a skillet or microwave for about 10-15 seconds to make them pliable, which helps prevent cracking while rolling.

Assemble Taquitos: Spread approximately 1/3 cup of the creamy filling on one side of each tortilla, then roll them tightly from one edge while leaving the ends open to seal in the delicious center.

Coat: Dip each rolled taquito in melted butter, allowing them to soak up the richness, and then roll them in the cinnamon sugar mixture for that delightful crunch and sweetness.

Bake: Arrange the coated taquitos on a greased baking sheet and bake in a preheated oven at 350°F for 15-20 minutes, until they are golden brown and crispy on the outside.

Cool and Serve: After baking, let the taquitos cool for a minute before serving, allowing the filling to set slightly, ensuring a perfect creamy texture when you take a bite.
