Cut the Pandoro cake into slices, and remove a circle of cake from the middle of each slice.
Mix the eggs and milk together, and dip all the cake slices in. Stack the slices on a lined baking tray, placing them slightly differently each time. Add the removed cake circles around the tray and bake for 10 minutes at 180°C.
Pour Nutella® into the Pandoro cake hole and place the Kinder Surprise® in the middle. Sprinkle with icing sugar and decorate with the Smarties®. Enjoy by dipping the cake circles into the chocolate fondue in the middle!
