step 1
Preheat the oven to 160C and line a square baking tray with greaseproof paper
step 2
Whisk the oil, eggs and caster sugar until pale and frothy
step 3
Melt the chocolate in a separate bowl over a saucepan of simmering water (don’t let the bottom of the bowl touch the water or it will burn the chocolate). Once melted, set aside and cool
step 4
Fold the cocoa and flour into the egg mixture and then mix in the cooled melted chocolate
step 5
Pour the mixture into the prepared tray and bake for 15 mins, then remove the tray from the oven and add the crushed Oreos. Then place the tray back in the oven for a further 25 mins. You want the middle to still be soft but the outer parts to be cooked.
step 6
Remove from the oven and let the brownie cool in it’s tray. It’s easier to cut into squares if fridge cold. Enjoy!
