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

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

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

Place a spoonful of the mixture on one half of each pastry strip, fold over and twist to seal.

Brush tops with beaten egg and bake for 15-20 minutes until golden brown.

Let cool for a few minutes before serving warm with your favorite dipping sauces.
