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 jalapeños, and garlic powder. Stir until smooth.

On a floured surface, roll out your puff pastry until about 1/4 inch thick. Cut the dough into 2-inch wide strips.

Position a spoonful of the filling on one half of each pastry strip. Fold the other half over and press to seal. Twist each strip.

Brush the tops with beaten egg and arrange on the baking sheet. Bake for 15-20 minutes until golden brown.

Cool for a few minutes on a wire rack before serving warm with dipping sauces.
