Preheat oven to 400 degrees.

Unroll the thawed pie crusts, and press into 5 (4" individual tart pans). If desired, use leaf pie crust cutters to cut out decorative leaf pie crusts. Place the prepared tart pans on a baking sheet. Set aside.

In a mixing bowl, whisk together the pumpkin, milk, pumpkin pie spice, sugar, egg and salt. Pour this mixture into the prepared tart pans, filling at least 3/4 full. Top the tarts with the decorative pie crust leaves.

Place the entire baking sheet with the filled tarts into a 400 degree oven, and bake for 35-40 minutes. Tarts are done when filling appears set when gently moved. Let tarts cooled completely to room temperature.

For whipped cream: With a hand or stand mixer, using a cold mixing bowl and whisk attachment, add the caviar of 1 vanilla bean (cut the vanilla bean lengthwise, in half and scrape out the inside with sharp knife). Add the the cold cream, sugar and vanilla as well. Whisk on high for about 1-2 minutes or until stiff peaks form. Don't over-whip or whipped cream will become lumpy and begin turning into butter.

Top the cooled tarts with a generous dollop of the whipped cream. Enjoy right away!
