Prepare the salted caramel by blending all the ingredients together until smooth (you may have to scrape the sides of the blender down a few times).
Place the matzah on a baking sheet. Use a spatula to spread the salted caramel over the two pieces. Place the baking sheet in the freezer for 10 minutes to firm up the caramel.
In a double boiler (or a small saucepan on the stove at low heat), melt the chocolate chips. Remove the baking sheet with the matzah from the freezer and spread the melted chocolate over the salted caramel layer.
Sprinkle the cacao nibs and sea salt flakes on top. Return the matzah to the freezer for 10 minutes to harden the chocolate. Use your hands to break the each piece of matzah into 8-10 pieces. Enjoy right away or store in the refrigerator.
