Preheat oven to 190°C. Spray a 22cm (2-litre/8-cup capacity) fluted ring cake pan with the non-stick cooking spray.
Beat butter or margarine and caster sugar in a mixing bowl with electric beaters until pale and creamy. Add the eggs one at a time, beating well after each addition. Fold in the sifted flour with a large metal spoon. Then fold in the orange rind and juice, and the marmalade until well combined. Spoon mixture into the prepared cake pan. Place pan on a baking tray and bake in preheated oven for 45-50 minutes or until golden and a skewer inserted into the cake comes out clean. Cover cake with foil for last 10 minutes of cooking to prevent it from over-browning.
To make the orange syrup, whisk together sifted icing sugar and orange juice in a bowl until icing sugar is dissolved. Remove cake from oven and stand in pan for 10 minutes before turning onto a serving plate. Use a pastry brush to generously brush the orange syrup over the cake until it has all been absorbed. Let cake cool.
To make the honey yoghurt, combine honey and yoghurt in a bowl. Serve cake with honey yoghurt sprinkled with cinnamon
