Preheat the oven to 160 degrees. Roll out the puff pastry to the thickness of a £1 coin (about 4mm). Use a star cutter (or a shape of your choice!) and cut out 16.
Place the pastry stars on a baking tray and prick the centres. In a bowl, mix the plums with the sukrin gold and mixed spice. Divide the plums between the star shapes, brush over some of the egg wash and place in the oven for 12 minutes.
Dust with Sukrin Icing Sugar and serve with a small bowl of yoghurt to dip (raspberry works really well!)
