In a large mixing bowl, combine the peanut butter, melted butter, almond flour, sugar-free confectioners sweetener and sea salt. Stir well until completely combined.
Line a 9” x 5” loaf pan or 8” x 8” cake pan with parchment paper.
Transfer the peanut butter mixture to the parchment-lined pan, and spread into an even layer.
Microwave the chocolate and butter in a microwave-safe bowl for 20 second intervals, stirring well between intervals, until melted, about 40 to 60 seconds.
When you’re ready to serve, remove the low carb peanut butter bars from the pan and transfer them to a cutting board. Use a sharp knife to slice desired sized bars. Enjoy!
