Keto Lemon Mascarpone Tart

To Make the Tart Crust

1. Preheat oven to 350°F. Prepare the pie crust dough according to the directions.
2. Add the pie crust to a 9 inch nonstick tart pan with a removable bottom. Press it out in an even layer, going up the sides of the pan.
3. Prick the bottom of the crust with a fork and bake for 15 minutes or until golden. If the edges brown too quickly, lightly cover them with aluminum foil.

To Make the Filling

1. Add the lemon curd, mascarpone, sweetener and most of the heavy cream in the bowl of a food processor. 
2. Mix until smooth and creamy.  If mixture is too thick, add the remaining heavy cream.
3. Pour the filing into the cooled tart crust and chill in the fridge for at least 1-2 hours or until set. Top with powdered sugar or whipped cream and sliced lemons.
