Preheat your oven to 400°F (200°C) to ensure your flautas bake evenly.
In a mixing bowl, combine the softened cream cheese, sharp cheddar cheese, shredded chicken, diced green onions, crushed red pepper, salt, and garlic powder. Mix until creamy.
Take a flour tortilla and spoon about 2-3 tablespoons of the filling mixture onto one side. Roll it tightly and place seam-side down on a baking sheet lined with parchment paper. Repeat with remaining tortillas.
Lightly spray or brush the tops of the flautas with cooking oil. Bake for about 15-20 minutes until crispy and golden brown.
Let cool slightly before serving with your favorite dipping sauces and enjoy!
