01 - Line an 8x8-inch baking pan with parchment paper, allowing overhang on opposite sides for easy removal later.
02 - In a medium mixing bowl, whisk together almond butter, melted coconut oil, maple syrup, vanilla extract, orange zest, orange juice, and sea salt until completely smooth and fully incorporated.
03 - Gently fold in the chopped toasted almonds and chocolate chips if using, distributing evenly throughout the mixture.
04 - Transfer the mixture to the prepared pan, spreading evenly with an offset spatula. Sprinkle the additional grated orange zest uniformly across the surface.
05 - Place the pan in the freezer for a minimum of 2 hours, or until the fudge is completely firm and set.
06 - Using the parchment paper overhang, lift the fudge block from the pan. Cut into 16 equal squares with a sharp knife. Store in an airtight container in the freezer and serve directly from frozen for optimal texture.
