01 - Line an 8x8-inch baking pan with parchment paper, leaving overhang on opposite sides for easy removal.
02 - Combine pitted dates and raw almonds in a food processor. Blend until finely chopped and mixture begins to clump together. Add cocoa powder, melted coconut oil, and sea salt. Continue processing until mixture holds together when pressed.
03 - Transfer the date-almond mixture to the prepared pan. Press firmly and evenly across the bottom to create a compact base layer.
04 - Place chopped dark chocolate, almond butter, and coconut oil in a heatproof bowl. Set over a pan of simmering water, stirring frequently until completely smooth and melted. Alternatively, microwave in 20-second intervals, stirring between each burst.
05 - Pour the melted chocolate mixture over the prepared base. Use a spatula to spread evenly, covering the entire surface.
06 - Sprinkle chopped toasted almonds evenly over the chocolate layer. Finish with flaky sea salt if desired.
07 - Refrigerate for at least 1 hour until chocolate is completely set and firm to the touch.
08 - Lift the fudge from the pan using the parchment paper overhang. Cut into 16 equal squares. Store in an airtight container in the refrigerator for up to 1 week.
