Preheat the oven to 200°C/400°F. Unroll the pastry onto a clean board. Using a 7 cm cutter stamp out 12 circles and use to line a bun tin. Put in the fridge for 30 minutes. Reserve the pastry trimmings.
Meanwhile in a bowl mix together the mincemeat, diced apple and dried cranberries. Spoon a little of the apple mincemeat into each pastry case.
Using the pastry trimmings stamp out 12 small star or heart shapes. Put a star or heart on the top of each mincemeat tart. Bake in the oven for 15- 20 minutes until lightly golden and cooked.
Leave to cool for 5 minutes then transfer to a wire rack and dust with icing sugar. Serve warm or cold.
