Roll out the puff pastry into a rectangle on parchment paper and cut it into 8 strips.

Cut each slice of prosciutto in half. Place a prune on each half slice and roll it up.

Place each prosciutto-wrapped prune on a strip of puff pastry.

Repeat the process on the opposite end of each strip, then cut the strips in the middle.

Roll each piece into a bite-sized bundle, pinching the edges to seal. Place a sheet of parchment paper on a baking sheet and arrange the bundles as you go.

Seal the bundles tightly by pressing the edges with the tines of a fork on each side. Chill the baking sheet in the refrigerator for 30 minutes.

Preheat the oven to 400°F (200°C). Bake for 15 minutes.

Flip the bundles halfway through baking.

Transfer to a serving platter right out of the oven and let cool slightly.

They're ready to serve! Enjoy!
