Step 1

Preheat the oven to 170°C. Grease and lightly flour a 2-litre bundt pan.

Step 2

Place butter and 1 cup sugar in an electric mixer and beat at a high speed until light and fluffy. Grate the rind from 2 oranges and add to the mixture. (Squeeze the juice from these 2 oranges and set aside.)

Step 3

Add eggs, one at a time, to the mixture, beating well after each addition. Add creme fraiche and marmalade, beating slowly until combined. Sift flour, bicarbonate soda and baking powder into the mixture, then use a metal spoon to carefully fold in the dry ingredients until combined.

Step 4

Place batter into prepared pan, smoothing the top. Bake for 50-60 minutes or until a skewer inserted into the centre comes out clean. Set aside to cool, then turn out onto a wire rack placed over a tray.

Step 5

To prepare the syrup, cut remaining oranges into thin slices and set aside. Place reserved orange juice, remaining sugar and 1 cup water in a saucepan over low heat, stirring until sugar has dissolved. Add orange slices and simmer for 10-15 minutes until the slices are transparent. Lay out on a wire rack and continue cooking syrup until well reduced.

Step 6

While the cake us still warm, use a skewer to make small holes over the surface, then drizzle with the syrup. Place orange slices on top of cake, twisting them to form a decorative pattern.
