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

In a mixing bowl, combine the cream cheese, shredded sharp cheddar cheese, sliced jalapenos, and garlic powder until smooth and creamy.

Unroll the thawed puff pastry on a lightly floured surface and roll it out to about 1/4 inch thick, then slice into 2-inch wide strips.

Spread a spoonful of cheese filling onto one half of a strip, fold over, pinch to seal, and twist to create spiral shapes.

Place the twisted pastries on the baking sheet and brush with beaten egg for a golden finish.

Bake in the preheated oven for 15-20 minutes, or until golden brown and puffed.

Remove from the oven, cool slightly, and serve warm with your favorite dipping sauces.
