Preheat Oven:
Preheat oven to 375°F (190°C). Grease a muffin tin or line with paper liners.

Prepare Sugar Mixture:
In a small bowl, mix granulated sugar and cinnamon. Set aside.

Roll Puff Pastry:
Roll out the puff pastry sheet on a lightly floured surface into a rectangle (about 12×12 inches). Brush melted butter evenly over the pastry.

Add Peach Filling:
Spread peach pie filling evenly over the buttered puff pastry, leaving a small border around the edges.

Cut and Roll:
Cut the pastry into strips about 2 inches wide. Roll each strip tightly from one end to the other, creating a spiral (like a cinnamon roll).

Coat with Sugar:
Roll each spiral in the cinnamon-sugar mixture until fully coated.

Place in Muffin Tin:
Place each coated spiral into a muffin cup, coil side up.

Bake:
Bake for 20–25 minutes or until golden brown and puffed.

Cool and Serve:
Let cool slightly, then dust with powdered sugar if desired. Serve warm and enjoy!
