Melt together the peanut butter, coconut oil, powdered swerve, and vanilla extract on the stovetop or in the microwave. Do the same with the chocolate chips, the rest of the coconut oil, and sea salt.
Place in the freezer for about 15 minutes (or until solid) and repeat the same thing with the peanut butter layer, spooning around 1/2 tablespoon on top of the chocolate layer.
