Preheat your oven to 350 degrees Fahrenheit. Line an 8×8 inch square baking pan with parchment paper for best results.
In a medium-sized bowl, mix together the almond flour, cooled coconut oil, maple syrup, vanilla extract, and a pinch of salt until they form a thick, crumbly texture.
Transfer the mixture into the prepared pan and use your fingertips to press it down evenly, forming a solid base. Bake for 8-10 minutes, then allow it to cool for about 10 minutes.
While the crust is cooling, sprinkle the chopped roasted peanuts evenly over it.
In a medium saucepan over medium-low heat, combine the peanut butter, maple syrup, coconut oil, vanilla extract, and a dash of sea salt. Heat for about 2 minutes until it starts to gently bubble, stirring frequently. Remove from heat and pour it evenly over the layer of peanuts and the slightly cooled crust.
Place the pan in the refrigerator for 30-60 minutes to allow the peanut butter layer to firm up, or speed up the process by placing it in the freezer for 15-20 minutes.
After chilling, melt the chocolate chips and coconut oil together in the microwave or on the stovetop until smooth. Pour the melted chocolate evenly over the peanut butter layer.
Return the pan to the refrigerator for at least 1 hour to allow the chocolate to solidify and the bars to cool completely.
Once set, remove the bars from the pan and cut them into 16 bars. Slice the slab in half, then cut each half into 8 bars measuring about 1 inch in width.
Enjoy your homemade bars! Store them covered in the refrigerator until you're ready to indulge.
