Step 1.  Preheat oven to 375 degrees F and line a 9" springform pan with parchment paper.

Step 2.  Add butter to a medium-sized bowl and melt in the microwave.  Once melted, add the almond flour, cocoa powder and sweetener. Mix well to combine.

Step 3.  Transfer the crust mixture to the prepared springform pan. Use your fingers to spread the crust so that it covers the bottom of the pan.

Step 4.  Using a fork, poke some holes in the crust to allow air to escape.  Bake for 10-12 minutes until set.  Allow to cool completely before making the filling.  The pie crust will harden as it cools.

Step 5.  Add the 1/2 cup heavy whipping cream to a large bowl and whip with an electric mixer until soft peaks form.  Set aside.

Step 6.  Add filling powdered sweetener, heavy whipping cream, and vanilla to a large bowl and mix with the electric mixer.  (No need to clean the blades.)  Add in softened cream cheese and peanut butter and mix on High until light and fluffy.

Step 7.  Carefully fold the whipped cream into the peanut butter mixture.  Add the filling to the cooled crust.

Step 8.  Chill for 1 hour in the freezer until completely cooled.

Step 9.  Remove the spring form pan and parchment paper.  (You can leave the bottom of the pan in place.)

Step 10.  Whisk chocolate topping ingredients together and drizzle over the pie.

Step 11.  Chill for 15 minutes in the freezer until chocolate hardens.

Step 12.  Store in the refrigerator.
