Method
Line a small baking sheet with parchment paper and set aside.
In a medium bowl, mix the chopped dates and almond butter until well combined and sticky.
Spread the date mixture evenly onto the prepared baking sheet, pressing into a 1/4-inch thick rectangle.
Drizzle the melted dark and white chocolate over the date layer, then swirl gently with a knife for a marbled effect.
Sprinkle the chopped almonds and flaky sea salt evenly over the top.
Freeze for 30 minutes, or until firm, then break into uneven pieces.
