Remove the pastry from the fridge, and roll out to a thickness of 0.5cm/¼in. Using a 7.5cm/3in fluted cutter, stamp out 12 discs from the pastry and use them to line a 12-hole muffin tin. Fill each hole with one teaspoon of the mincemeat mixture plus a small chunk of chocolate, and brush the edges with plant milk.

Using a 6cm star cutter, cut out 12 stars and use them to top the mince pies, pressing the edges together.

Brush the top of each mince pie with more plant milk.
