Preheat the oven to 180°c and line a large baking tray with baking paper (don’t use foil as it sticks).
Snap biscuits in half and line the bottom of the tray with them.
In a small saucepan on a medium heat, combine sugar and butter. Bring butter and sugar mix to the boil, reduce to a low heat as soon as it boils, and simmer for 5 minutes ONLY! Use a timer for this part.
Pour the mix on top of biscuits and use a spatula to spread it out.
Pop the tray in the oven and bake for 5 minutes until the mix is bubbling and spread out.
Remove from the oven and immediately sprinkle chocolate drops on top.
Allow to sit for a minute until chocolate softens and spreads out with a spatula. You can always pop it back in the oven for 1 minute to speed up this process.
Allow to set in the fridge for 2 hours.
Snap or cut into pieces.
