Preheat the oven to 360°F.
Cut the dough in 8 equal squares.
Spread each square with the rolling pin.
Cut a border inside each square.
Beat the egg and brush the border edges.
Fold all the outer edges on the inside square.
Line a baking tray with parchment paper.
Transfer the squares in the tray.
Place a dollop of creamy cheese on each of the squares.
Cut the pears in halves, remove the core, and then slice them.
Cut the slices in halves again, so you will get a quarter of a pear, sliced.
Place a pear quarter on each mini tart.
Brush the edges with the beaten egg.
Sprinkle a lot of Demerara sugar.
Bake for 18-20 minutes until golden brown.
