Crumb the chocolate cake using a fork. Bind the crumbs using the nutella. The nutella should be soft and pourable. You may want to put the bottle of nutella in a jug of hot water before using. Once you have binded the cake crumbs well, it should form a huge ball. Make small balls and leave aside on a wax wrap. Dip the end of the lollipop sticks in a bit of melted chocolate and stick into the balls to form cake pops. Put into the fridge for atleast 4 hours. Melt the slabs of chocolate in a bowl over a little boiling water on the stove. Remove cake pops from frige. Roll into chocolate. Sprinkle beads for decoration. Set aside to dry on wax wrap. Remove them only when they are completly dry! Store in an air tight container.
