Line a baking tray with parchment paper.

Put 2 whole matzah sheets on the baking tray.

In a medium heavy-based saucepan, melt the butter and brown sugar together stirring until the sugar has fully dissolved. Once it has melted allow it to come up to a boil, then leave it to bubble for at least three minutes, stirring from time to time.

Take off the heat, add the salt and vanilla, stir again and immediately pour it over the matzah and quickly spread it out evenly. Take care – it will be hot!  Top tip: if the fat butter splits out from the sugar — it will look oily – then take it the pan off the heat, allow the caramel to cool a little then add a splash of hot water and whisk briskly. It should come back together. If not, the recipe will still work, it just looks less pretty and the texture will be slightly different.

Place in the oven for 15 minutes to cook the caramel further — keep an eye on it to make sure it does not burn.

Remove from oven and immediately sprinkle with the chocolate chips. Leave for five minutes to allow them to melt then spread them evenly across the caramel.

Sprinkle with toasted chopped nuts and/or sea salt to make it even more memorable.
