Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper to keep things tidy.
Unroll the puff pastry onto a lightly floured surface and cut it into long strips about 1.5 cm wide—that’s perfect for wrapping.
Wrap each hot dog snugly with a pastry strip, leaving some gaps to create a ragged, mummy-like appearance—tangle the strips for a chaotic effect.
Place the wrapped hot dogs onto your prepared baking sheet, spacing them out evenly so they have room to puff up and turn golden.
Brush the pastry lightly with beaten egg to give them a shiny, golden finish, and sprinkle with garlic powder or paprika if you like a smoky hint.
Bake for about 15–20 minutes, or until the pastry is puffed, golden, and crispy with a fragrant buttery smell filling the kitchen.
Check halfway through baking—if edges brown too quickly, cover loosely with foil to prevent burning while the centers finish crisping up.
Once baked, remove from the oven and let them rest on a cooling rack for about 5 minutes—this helps the cheese set slightly and makes handling easier.
Use tiny slices of olive as spooky eyes by placing them on the cheese while still warm, pressing gently so they stay in place.
Serve your spooky, crispy mummy hot dogs immediately, enjoying the crispy pastry, melted cheese, and fun, monster-like appearance.
