Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine softened cream cheese, shredded cheddar cheese, sliced jalapenos, and garlic powder. Mix until smooth.

Roll out the thawed puff pastry on a floured surface to about 1/4 inch thick and cut into strips approximately 2 inches wide.

Place a spoonful of filling on one half of each pastry strip, fold it over, and pinch the edges to seal. Twist the ends to shape.

Beat the egg and use it to coat the tops of each twist for a golden finish.

Bake the twists for 15-20 minutes or until golden brown. Keep an eye on them to prevent burning.
