Mars Bar Balls

You will need:
250g shortbread biscuits, broken up
20g cocoa powder
200g sweetened condensed milk
5 fun size mars bars, cut into four pieces each

Place biscuits into the bowl. Blitz on speed 7 until desired consistency. These can be as fine or coarse as you like.
Add cocoa and blitz on speed 5 for 6 seconds.
Add condensed milk and blitz on speed 4 until a dough forms.
I was able to roll straight away but if you find the shapes collapse slightly, refrigerate it for 30 mins or so.
Get a small piece of “dough”, flatten slightly and place a cube of mars bar in the middle and mould the dough around it. Roll into a smooth ball shape and roll into sprinkles.
Keep in the fridge.
