Begin by preparing your workspace. Line an 8x8 inch baking dish with parchment paper, ensuring that there’s an overhang on the sides.
In a medium-sized mixing bowl, combine the natural peanut butter, pure maple syrup, melted and slightly cooled coconut oil, and pure vanilla extract. Whisk thoroughly until the mixture is smooth and well blended.
In a separate bowl, sift the unsweetened cocoa powder to eliminate any lumps, then add the fine sea salt. Gradually fold the cocoa mixture into the peanut butter mixture, using a spatula, until it is fully incorporated and smooth.
To melt the dairy-free dark chocolate chips, place them in a microwave-safe bowl. Microwave them in 30-second intervals, stirring well between each interval, until the chocolate is completely smooth and melted.
Pour the melted chocolate into the peanut butter mixture and stir until everything is combined into a creamy fudge batter.
Transfer the fudge batter into the prepared baking dish. Use a spatula to evenly spread the mixture into the corners and flatten the top.
If desired, sprinkle chopped nuts on top of the fudge for an added crunch and flavor boost.
Place the baking dish in the refrigerator and let the fudge chill for about 2-3 hours, or until it is fully set and firm to the touch.
Once the fudge is set, carefully lift it out of the dish using the parchment paper overhang and place it on a cutting board. Slice the fudge into squares for serving.
Any leftovers can be stored in an airtight container in the refrigerator, where they'll stay fresh for up to a week.
Notes
For an appealing display, arrange the fudge squares on a cute serving platter and garnish with a sprinkle of sea salt or a drizzle of melted chocolate for added flair.
