Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper and lightly spray with cooking spray to ensure easy removal.
Unroll the pastry dough and cut it into thin, strips approximately 1/4 inch wide. This will become the mummy wrapping.
Place each hot dog on a clean surface and gently stretch the pastry strips if needed.
Wrap the hot dogs entirely with the pastry strips, overlapping slightly to mimic mummy bandages. Leave a small space at one end to resemble the face area.
Arrange the wrapped hot dogs on the prepared baking sheet, spacing them evenly.
Bake in the preheated oven for about 12-15 minutes, or until the pastry is golden brown and crispy.
Remove the mummy hot dogs from the oven and let them cool slightly. Place two googly eyes on each mummy at the face area for a fun, spooky effect.
Serve these playful treats warm, with your favorite dipping sauce or as a festive appetizer.
