Place puff pastry on a parchment lined baked sheet and prick with a fork.
Spray the bottom of another baking sheet and place on top of puff pastry. This helps to keep the puff pastry flat. Bake for about 12-15 minutes until bottom to brown.
Remove baked puff pastry from oven and set aside until cooled completely.
In a small bowl mix mascarpone cheese, sugar, vanilla and lemon zest.
Spread on top of cooled pastry.
Top with fresh berries and sprinkle with lemon zest or a dusting of confectioners’ sugar.
