Carefully twist apart 8 Oreos then cut each half down the middle to make your bat 'wings' (each Oreo will make 4 wings). The best way to slice them is to press straight down with a sharp knife in one quick motion, rather than sawing. Don't worry if some break as you can use those pieces in the next step. You'll need 30 wings in total (enough for 15 bats).
Place 2 packs of Oreos (308g) into a food processor or high-powered blender. Blitz them into fine crumbs.
Add the Oreo crumbs to a large bowl with the cream cheese. Mix well then use your hands to press it together into a large ball.
Divide the mixture into 15 equal-sized pieces and roll each piece into a ball. Place them onto a lined baking tray then pop them in the fridge to chill for 1 hour.
Melt the milk chocolate then dip each truffle, tapping gently to get rid of any excess. Set them back onto your lined tray then carefully push an Oreo wing into each side. Finish each one with two edible eyes.
Chill in the fridge for 2 more hours then enjoy!
