Orange Olive Oil Bundt Cake with Orange Rosemary Syrup

This beautiful moist cake is bursting with orange flavour. As well as zest and juice, the cake also has Cointreau and marmalade added to give even more punch. This is a wonderful dessert cake with cream or ice cream but a slice is also delicious with a cuppa!

  • Bundt tin/pan - 10 cup capacity
  • pastry brush for preparing tin
  • 2 large bowls
  • hand whisk
  • zester



    Dry Ingredients:

    • 300 g plain flour 2 cups
    • 1 tsp baking powder
    • 1/2 tsp baking soda
    • 3/4 tsp sea salt coarse

    Wet Ingredients:

    • 220 g sugar granulated, (1 cup)
    • 3 eggs large (approx 52g each)
    • 185 ml olive oil extra virgin, (3/4 cup)
    • 185 ml buttermilk or milk (3/4 cup)
    • 60 ml orange juice freshly squeezed (1/4 cup)
    • 60 ml Cointreau liqueur
    • 4 large oranges (zest of 4 large oranges) finely zested
    • 2 large lemons (zest of 2 large lemons) finely zested, or 3 small/medium
    • 40 g orange marmalade 1 heaped 20ml tablespoon

    To prepare tin:

    • 15 g butter melted
    • flour extra (approx 2-3 tablespoons)


    • 110 g caster sugar 1/2 cup
    • 60 ml Cointreau (or Grand Marnier) 1/4 cup - you can use orange juice instead, if you don’t want to use liqueur
    • 60 ml orange juice 1/4 cup
    • 40 ml lemon juice 2 tablespoons
    • 3 rosemary sprigs 5cm long, washed (optional)


    • Preheat the oven to 170°C. Prepare the bundt tin by brushing the inside of the tin with melted butter and dust with flour - see notes.


    • In a large bowl, combine the flour, baking powder, baking soda and sea salt. Give a little whisk to combine and set aside.
    • In another large bowl, add the sugar and the eggs. Whisk them so they are well combined. Add all the remaining wet ingredients: olive oil, buttermilk, orange juice, orange and lemon zest, cointreau and marmalade. Whisk again so everything is incorporated.
    • Now it’s time to mix the wet ingredients into the dry ingredients: Make a well in the centre of the dry ingredients and add 1/2 the wet mixture. Stir gently with a large spoon or whisk, then add the remaining wet ingredients and mix gently until everything is combined and smooth.
    • Pour the cake mixture into the prepared bundt tin. Tap the tin gently on the kitchen bench to remove any air bubbles in the batter. Bake in the preheated oven at 170°C for 40-50 minutes until the cake is just cooked, or until a skewer inserted into the middle of the cake comes out clean. My cake took 42 minutes, but check the cake from the 30-35 minute mark as all oven temperatures vary slightly, and you don’t want to overcook the cake. Don't be concerned if the cake rises and cracks a little on the top as this can be trimmed once it has come out of the oven and cooled down.
      Take the cake out of the oven and let it rest in the tin for 15 mins before turning out onto a wire rack. To do this, hold the wire rack over the tin and turn the cake and rack over so the cake comes out gently. Rest on the wire rack for a further 15 minutes. Once cooled, you can turn the cake over gently and trim the base with a serrated knife so it sits flatter on the plate (optional). I trim mine a little (the offcuts taste amazing)!
    • Serve the cake as is, with a dusting of icing sugar and serve with whipped cream. Great with a cuppa.
      Or, serve as a dessert, with Orange Rosemary Syrup and whipped cream or ice-cream. Decorate the cake with glace oranges, zest and/or rosemary flowers or any edible flowers (optional).
      If you prefer to drizzle the syrup over the cake, do this just before serving, and then decorate the cake with flowers or zest etc.

    Orange Rosemary Syrup

    • Bring all the ingredients to the boil in a medium sized heavy-based saucepan, stirring to dissolve the sugar. Let it boil for 3-5 minutes until reduced and syrupy. Remove the rosemary sprigs and let the syrup cool to room temperature.
      Once cooled, store in a sealed jar or container at room temperature until required.
    • I like to serve the Orange Syrup in a little jug alongside the cake and let people help themselves, however you can drizzle the syrup over the cake and serve.

    How To Prepare A Bundt Tin/Pan

    This is a step you want to do properly. It is very easy to do and avoids any cake sticking to the pan when you turn it out.
    All you need is a soft bristled pastry brush, some melted butter and plain flour.
    • Step 1: Dip the pastry brush into the melted butter and 'paint' butter all over the inside of the tin, making sure you get into all the crevices. I like to start with the middle ring, then down into the base, and then up the sides, working around the tin the same way so I don’t miss any areas.
    • Step 2: Put 2-3 tablespoons of plain flour into the tin - I often shake some around the ring first. Dust the tin with flour by moving and tapping the pan in one direction and then in the other, so that all parts of the tin is coated with flour. You might find you need to sprinkle a little more flour in one area. Once the tin is completely coated in flour, turn the tin upside down over the sink and tap gently on the side of the sink or with your hand on the tin to remove all the excess flour. You only want to be left with a very fine coating of flour (too much flour will transfer to the cake and leave white marks). Check to make sure there are no gaps. If there is, just brush a little more butter onto the gap, dust with flour and tap out excess.
