Preheat oven to 350° and ensure rack is in lower part of oven.
Prepare pastry and allow to rest for 30 minutes before rolling. Roll half of dough into rectangle and cut out 6 tarts using a biscuit cutter or martini glass that is at least one inch large than muffin tin hole. Repeat with remaining pastry.
Lower pastry circles into tart tins, pinching and arranging into even circles.
Combine all ingredients in filling and beat on medium speed until well blended and slightly fluffy. Spoon evenly into tart shells, do not over fill.
Bake for 20 minutes until filling is bubbling and pastry is golden brown.
Allow to cool slightly before attempting to remove from the tins.
