Rich, decadent and perfectly balanced with sweetness from chocolate, bitterness from guinness, nuttiness from tahini and saltiness from crunchy sea salt flakes - these are grownup brownies with a difference.

Everyone loves a chocolate brownie and when something is so loved, it can be dangerous to mess with. But the twists in this brownie recipe only elevate the humble brownie to the next level. The brownie itself is super fudgy, chocolatey and decadent, while some walnuts bring texture, tahini adds a lovely nutty creaminess and the miso tamarind caramel is salty, sour and fruity to cut through the richness of the chocolate. Sheer heaven.
