In a large mixing bowl, combine the creamy peanut butter, honey (or maple syrup), and vanilla extract. Stir until smooth.
Gradually add in the rolled oats and graham cracker crumbs, mixing until fully combined. The mixture should be thick and sticky.
Line an 8x8-inch baking dish with parchment paper, leaving some overhang for easy removal.
Spread the peanut butter mixture evenly in the prepared baking dish, pressing it down firmly with your hands or a spatula to ensure it’s compact.
In a small microwave-safe bowl, combine the dark chocolate chips and coconut oil. Microwave in 30-second intervals, stirring in between until melted and smooth.
Pour the melted chocolate over the peanut butter layer, spreading it evenly with a spatula.
Sprinkle a pinch of salt over the chocolate layer for an extra flavor boost.
Refrigerate for at least 2 hours or until the bars are firm.
Once set, lift the bars out of the dish using the parchment overhang and cut into squares or rectangles.
Notes
Serve the bars on a decorative platter, drizzled with extra melted chocolate or topped with crushed peanuts for added texture and visual appeal.
