Preheat the oven to 400° F. Line a large baking sheet with parchment paper.
Roll out the puff pastry dough a bit. Cut each sheet into 9 squares.
Place 2 raspberries and 1 Rolo candy in the center of a square. Moisten the edges with a little water.
Bring two opposite corners of the square up to meet each other, and pinch down the sides to seal them together. Make a pouch by pulling the other two corners up, and then roll the top to seal the filling inside.
Place it on the prepared baking sheet.
Repeat with remaining dough squares, raspberries, and Rolos.
Brush the tops of the pastries with half and half using a pastry brush. Sprinkle decorating sugar generously over the tops.
Bake the turnovers for about 18 minutes, until the tops are light golden brown. Remove them from the baking sheet to a serving plate.
Let the turnovers cool for 10 minutes, then serve them while they're still warm. Makes 18 in all.
Notes
How do I thaw puff pastry quickly?
The very best way to thaw puff pastry is by letting it defrost in the refrigerator overnight. This method keeps the butter in the dough firm which is what gives the puff pastry its wonderful layers and flakiness.If you forgot to defrost your puff pastry in the fridge, you can let it sit out at room temperature for 20-30 minutes. Press your finger in the dough every few minutes to check the thawing. Unfold and use the pastry as soon as it's soft enough—don't let it get too warm.
