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

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

Lightly flour a clean surface and roll out the dough to about 1/4 inch thickness. Slice into 2-inch-wide strips.

Spoon a generous amount of the filling onto one half of each strip, fold over, and press edges to seal.

Twist each sealed pastry strip into a spiral shape and place them on the prepared baking sheet.

Whisk the egg and brush it over each twisted pastry.

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