Decadent Vanilla Custard Tarts

These were a big hit!  A nice creamy texture and very simple to make.

1 box (225g) Tart Shells
3/4 cup 10% cream
1/3 cup granulated sugar
1 tbsp cornstarch
2 egg yolks
2 tsp vanilla extract
1/4 tsp salt
1/4 cup icing sugar
2 tsp ground cinnamon

1. Preheat oven to 375F.  Arrange tart shells on a baking sheet.  Prick bottoms with a fork.  Bake on bottom rack for 6 minutes, set aside and cool completely.  Reduce oven temperature to 325F.
2. Meanwhile, heat cream in a microwave safe bowl for 1 minute or until steaming.  Stir sugar with cornstarch in a separate bowl until combined.  Stir in yolks, vanilla and salt until well combined.  Gradually stir in cream, careful not to create a lot of air bubbles.
3. Strain custard through a fine mesh sieve and skim off any residual foam; divide evenly among prepared tart shells.  Bake on bottom rack for 20 minutes or until just slightly jiggly in the centre. Cool to room temperature.  
4. Stir icing sugar with ground cinnamon, just before serving, sift sugar mixture over tarts.
