Weigh out 10 lots of 25g balls of the cake mixture and place on a tray lined with grease proof paper. Then place a cocktail stick in each of them. Then weigh out another 10 balls this time weighing 15g and place onto the 25g balls, piercing them through the cocktail stick. Finally use the rest of the cake mixture to make 10, 10g balls then place those, through the cocktail sticks, onto the 15g balls.
