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

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

Roll out the thawed puff pastry until 1/4 inch thick and cut into 2-inch wide strips.

Spoon 1 tablespoon of filling onto one half of each pastry strip, fold over, and twist the ends to seal.

Whisk the egg and brush it over the tops of each twist for a golden finish.

Bake for 15–20 minutes until golden brown and flaky, watching carefully during the last few minutes.
