Preheat: Preheat your oven to 375°F (190°C); then line a baking sheet with parchment paper.
Prepare pastry strips: Unroll the puff pastry and cut into thin strips (about ½ inch / 1 cm wide).
Wrap the hot dogs: Next, wrap each hot dog in pastry strips, leaving a small gap near the top for the “face.”
Brush with egg: Meanwhile, place the wrapped hot dogs on the baking sheet and brush with beaten egg for a golden finish.
Bake: Finally, bake for 12–15 minutes, or until the pastry is puffed and golden brown. Let cool slightly before adding small dots of mustard or ketchup for the eyes.
Tips & Variations
Add a slice of cheese under the pastry for extra gooeyness.
Use mini sausages for bite-size appetizers.
For a sweeter version, try wrapping banana halves in puff pastry and dusting with cinnamon sugar.
