In a mixing bowl, combine the peanut butter, cream cheese, almond flour, confectioners sugar substitute and vanilla extract. Beat on high until well combined. Add the chopped peanuts at this time if you would like to add some extra crunch to your candy bars.
Press the dough mixture into a rectangular candy bar mold until the sections are ¾ of the way full.
Place the mold into the freezer to set for at least an hour.
Add the Lily’s baking chips and the coconut oil to a microwave safe bowl. Heat for 30 second intervals until the chocolate is melted and the mixture is well combined.
Place a layer of the chocolate mixture onto the top of each of the candy bars in the mold, and return to the freezer until the chocolate and bars are completely set.
