Step 1: 1. Melt half of the chocolate in a bowl, add the butter and syrup and mix together (you may want to melt the butter beforehand to make it easier to combine)
Step 3: 2. Add the crushed biscuits and whole malteasers and mix together.
Step 5: 3. Spread out onto a tray
Step 7: 4. Melt the rest of the chocolate and pour/spread on top of the stuff in the tray
Step 9: 5. If you have white chocolate, melt some and splatter it over randomly and grate some more over that (or do whatever you want with it, its for decoration/taste!)
Step 11: 6. Put in the fridge and let it set for a few hours before slicing up and tucking in!
