Preheat your oven to 350 F and cover a foil-lined baking sheet with matzo leaving no empty spaces.
Heat the butter and sugar over medium-low heat until melted, then increase the heat to medium and bring it to a boil, stirring the whole time. Boil for 3 minutes then remove from the heat and mix in the vanilla and a healthy pinch of sea salt.
Pour the caramel mixture over the matzo immediately and shmear it around to spread it as evenly as possible.
Lower the heat to 325 F and put the caramel-covered matzo in the oven for 15 minutes – watch it closely so it doesn't burn.
Take your delicious smelling matzoh out of the oven and pour your chocolate chips over it, and let sit for 5 minutes while they melt.
Shmear the chocolate across your matzoh with a spatula to coat it evenly. Let it sit out for a few hours until hard or in the fridge for a few hours.
Once the Matzoh Crunch is hardened, crack the pieces up and try not to eat the entire thing in one sitting!
