1. Place the butter into a saucepan and place on a low heat and melt.

2. Add in the dark chocolate broken up and melt in with the butter, stir with a wooden spoon until completely melted and smooth.

3. Take off the heat and add in the caster sugar and vanilla extra, mix in until well combined.

4. Allow to cool for 4 or 5 mins then beat in the eggs one at a time.

5. Finely chop your black garlic or use a garlic rocker (best tool ever, if you don't have one) to crush it, it is very soft and mushy so doesn't make much breaking up (you could also use black garlic paste which is available in some supermarkets if you can't get black garlic bulbs). Add the black garlic into your brownie mix and beat in well.

6. Chuck in your chocolate chips and fold in the flour, make sure it is all combined to make a nice glossy mix.

7. Grease and line a 8inch square cake tin and pour in your batter. Place in an oven preheated to gas mark 3 and bake for 30 mins, this will give a beautiful moist brownie. Cool for 10 mins before removing from the tin and slicing up, best eaten warm!

If you are not sure where to buy black garlic....
You can get the cloves in a tub off The Garlic Farm (or from their farm shop if you are on Isle of Wight, I bought mine from there while on holiday) or they also sell the bulbs
You can buy from some Sainsburys or online
Or you can get the paste off Ocado and I think also in Waitrose. I would suggest using cloves as the paste contains oil, but if you can't get them but this would work too - you would need approx 7tsps.
