Place the peanuts in a food processor and pulse until it reaches a graham cracker crumb consistency. (see photos in post)
Push the crushed peanuts to one side of the processor and add the melted butter, sweetener, and peanut butter. Pulse several times until well blended. You will need to stop and scrape down the sides as you go.
Add the coconut flour and vanilla extract, pulse a few more times.
Pour the batter (it will be thick, but easy to scrape out) of the food processor into a parchement paper lined 8x8 pan. Spread the peanut butter into a nice smooth layer. Chill for 30 minutes.
In a small sauce pan heat the heavy cream. When it is piping hot add the chopped chocolate and peanut butter. Remove from the heat and stir until the mixture is smooth. Pour over the peanut butter layer and chill at least 1 hour before cutting.
