01 - Line a baking sheet with parchment paper. Break matzo sheets into large pieces and arrange in a single layer on the prepared sheet.
02 - Melt the chocolate and butter together in a heatproof bowl set over a saucepan of simmering water, stirring continuously until smooth and fully combined. Alternatively, microwave in 20-second intervals, stirring between each, until completely melted.
03 - Pour the melted chocolate mixture evenly over the arranged matzo pieces. Use a spatula to spread the chocolate, ensuring each piece is thoroughly coated.
04 - Immediately sprinkle chopped nuts, dried fruit, and flaky sea salt over the chocolate-coated matzo while the chocolate is still melted to ensure toppings adhere properly.
05 - Refrigerate the baking sheet for at least 30 minutes, or until the chocolate has completely hardened and set.
06 - Break the chilled chocolate-covered matzo into smaller pieces and serve immediately or store for later enjoyment.
