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

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

Roll out thawed puff pastry on a floured surface to 1/4 inch thickness and cut into 2-inch wide strips.

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

Whisk the egg and brush it generously over each twisted pastry.

Place the twists on the lined baking sheet and bake for 15-20 minutes until golden brown.
