Preheat your oven to 350°F (180°C) and line a baking sheet with parchment paper.

In a medium bowl, mix the crab meat, cream cheese, green onions, garlic powder, and soy sauce until well blended.

Roll out the thawed puff pastry on a lightly floured surface and cut into 3-inch squares.

Place a small spoonful of the crab mixture onto each square, fold the corners over to seal, and press down the edges.

Whisk together one egg with a splash of water and brush the tops of each pinwheel with the egg wash.

Space the pinwheels about an inch apart on the prepared baking sheet.

Bake in the preheated oven for 20-25 minutes until golden brown.

Let cool for a few minutes, then serve warm with dipping sauces.
