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. Blend until smooth.

Roll out the thawed puff pastry to about ¼ inch thick and cut into 2-inch wide strips.

Place a spoonful of the jalapeno filling onto half of each pastry strip. Fold over and seal edges, then twist the strip.

Beat an egg and apply egg wash to the tops of each twisted pastry.

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

Remove from oven and let cool for a few minutes. Serve warm with your favorite dipping sauce.
