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 sharp cheddar cheese, sliced jalapenos, and garlic powder. Mix until smooth.

Unfold the thawed puff pastry on a lightly floured surface and roll it to about 1/4 inch thick. Cut into strips approximately 2 inches wide.

Spoon a generous amount of the cheese mixture onto one half of each pastry strip, fold, and twist to seal the filling.

Place the filled pastries on the prepared baking sheet, ensuring there's space between each twist.

Whisk an egg and brush the tops of each twist with the egg wash.

Bake for 15-20 minutes until golden brown and puffed up.
