Low carb pumpkin pie

Pie Crust

1. Preheat oven to 350°F (175°C).

2. Add the butter, almond flour, hazelnut flour, sweetener, cinnamon, vanilla, and salt to a medium-sized bowl. Mix together until crumbly, and well combined.

3. Evenly press the crust mixture over the bottom and sides of a 9" (23 cm), un-greased pie plate. Set aside.

Pumpkin filling

1. In a medium-sized bowl, use a hand mixer to combine the pumpkin purée, sweetener, butter, cinnamon, pumpkin pie spice, and salt. Pour in the egg and the heavy whipping cream, and mix until just combined.

2. Pour the filling into the pie crust. Place aluminum foil or a pie shield along the crust edges, to prevent browning too quickly. Bake on the middle oven rack for 35-40 minutes, or until the filling is just set.

3. Cool on a wire rack for 2 hours, or until at room temperature. Serve at room temperature or refrigerate for several hours before serving.

Whipped cream topping

1. Add the heavy cream, vanilla, and sweetener to a medium-sized bowl. Using an electric mixer, whisk at medium speed, until soft peaks form.

2. For serving, slice the pie, and top with a dollop of whipped cream, and a sprinkle of cinnamon if desired.
