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

In a mixing bowl, combine cream cheese, cheddar cheese, sliced jalapenos, and garlic powder. Stir until smooth.

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

Place a spoonful of filling on one half of each pastry strip, fold over, and seal edges tightly. Twist each strip to form a spiral shape.

Arrange on the baking sheet, beat the egg, and brush the tops with egg wash.

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

Let cool for a minute or two before serving warm with dipping sauce.
