Ingredients
4lightly salted matzos,(preferably the Streit’s brand)
1cupunsalted butter,(2 sticks)
1cupdark brown sugar,firmly packed
12ozsemisweet chocolate chips,(1 bag)
1cuppecans,(toasted if desired for maximum flavor), chopped
½tspsea salt flakes,or kosher salt
Preparation
Preheat the oven to 350 degrees F. Line a rimmed baking sheet with heavy duty aluminum foil, making sure the foil goes up and over the edges, and top with a sheet of parchment paper.
Cover the baking sheet with the matzos, cutting and piecing them together as necessary to fill the entire pan.
Combine butter and brown sugar in a medium saucepan. Cook over medium heat, stirring constantly with a whisk, until the mixture comes to a boil. (If it looks like it’s separating, just keep stirring; it will come together.)
Once the mixture comes to a boil, continue cooking and stirring for another 3 minutes until foamy and thickened. (Be extra careful — the toffee will be very hot!) Immediately pour the toffee over the matzos and, using a spatula, spread it into an even layer.
Put the pan into the oven and bake for 8 to 10 minutes, or until the toffee topping is crackled and bubbling all over. Remove the pan from the oven and place on wire cooling rack on the counter.
Immediately scatter the chocolate chips evenly over top. Wait 3 to 5 minutes for the chips to soften, then use an offset spatula to spread the chocolate into an even layer.
Sprinkle with the pecans and sea salt. Refrigerate for about 45 minutes until the chocolate is firm. Don’t leave it in the fridge too much longer, otherwise it will be hard to cut.
Lift the foil overhang to transfer the matzo crack onto a large cutting board. Using a large sharp knife, cut into 2-inch squares.
Store in an airtight container in the fridge and serve cold.
