Step 1

Preheat oven to 325 degrees and grease a 9 inch tart pan.

Step 2

Combine ingredients for crust and press into the bottom and up the sides of the pan.

Step 3

Bake crust for 7 minutes, then remove from oven and allow to cool completely.

Step 4

To make the whipped cream, whip heavy whipping cream on high speed for 2-3 minutes. Cream will initially bubble a little bit, then start to thicken.

Step 5

As the cream starts to thicken, add 1/4 cup of powdered sugar.

Step 6

Whip on high until stiff peaks form, for a total whipping time of about 5-7 minutes.

Step 7

Set whipped cream aside and combine mascarpone cheese, remaining powdered sugar, vanilla extract and cinnamon. Mix on slow speed until combined. Do not over mix.

Step 8

Carefully fold the whipped cream into the mascarpone mixture.

Step 9

Spread filling into the tart crust and refrigerate until firm, 3-4 hours.
