Preheat oven to 190 degrees C. Lightly grease a 23x23cm baking dish.
Cover the bottom of the prepared dish with matzohs, breaking and fitting pieces into spaces as needed.
Cook the margarine and brown sugar in a heavy-bottomed saucepan over medium-low heat until the mixture is well combined and bubbling, about 3 minutes; pour over the matzohs in the baking dish.
Bake in the preheated oven until the syrup is thickened and bubbling, about 15 minutes. Remove from the oven and sprinkle evenly with chocolate chips. Let stand for 5 minutes to melt the chocolate, then spread the melted chocolate evenly with a spatula. Cool completely and break into pieces to serve.
