Each ingredient in this recipe plays an essential role—whether it’s lending structure, moisture, or bold flavor. What’s truly exciting is how simple this lineup is, making the cake approachable yet absolutely irresistible.

Water (400 ml): Provides the base for the candied oranges and helps dissolve the sugar for that perfect syrup consistency.
Caster Sugar (430 g total): Used both for the candied oranges and the cake, caster sugar dissolves quickly and sweetens the batter uniformly.
Blood Oranges (3): Thinly sliced for stunningly beautiful and tangy candied decorations that elevate the cake’s flavor profile.
Fresh Rosemary (1 sprig + 1 tbsp finely chopped): Adds a fragrant, pine-like aroma to the candied oranges and the cake itself, tying the flavors together beautifully.
Large Eggs (3): Create structure and richness in the cake batter.
Vanilla Extract (2 tsp): Brings warmth and sweetness, enhancing the chocolate and rosemary notes.
Plain Flour (250 g): The foundation for the cake’s tender crumb, keeping it light yet substantial.
Baking Powder (2 ½ tsp): Ensures the cake rises perfectly, contributing to its fluffy texture.
Cacao or Cocoa Powder (75 g): Gives the cake that intense chocolate flavor that pairs beautifully with citrus and herbs.
Extra Virgin Olive Oil (200 ml): Creates a moist, tender crumb and adds a subtle fruity undertone distinct from butter.
Full Fat Milk (70 ml): Moisturizes the batter for a luscious softness.
Salt (¼ tsp): Balances the sweetness and enhances the depth of all the other flavors.

How to Make Chocolate, Olive Oil, and Rosemary Cake with Candied Blood Oranges Recipe

Step 1: Prepare the Candied Oranges

Start by creating the irresistible candied blood oranges that will crown your cake with beauty and brightness. Gently heat water and caster sugar in a saucepan until the sugar dissolves completely. Add the thinly sliced blood oranges and a sprig of fresh rosemary, then simmer slowly for about 45 minutes. The key here is to keep the orange slices submerged for even candying, turning them occasionally. When the peels become tender and translucent, remove them carefully and let them dry on parchment paper. Reserve the syrup; it’s pure gold and will be used later to soak the cake and drizzle on top, adding bursts of juicy sweetness.

Step 2: Whisk Together the Eggs and Sugars

While the oranges candy, prep the cake batter by whisking large eggs with both caster and light brown sugar until thick, pale, and fluffy. This aeration step is crucial as it creates a light texture. The duo of sugars not only sweetens the cake but also adds complexity, with the brown sugar bringing a subtle caramel note. Finish by folding in the vanilla for a fragrant touch.

Step 3: Combine Your Dry Ingredients

Next, sift together plain flour, baking powder, and cocoa powder. Sifting ensures no lumps and encourages an even crumb. Incorporating dry ingredients gradually into the wet mixture prevents overmixing, which can make cakes tough. Begin folding gently until the batter takes on a thick, somewhat sticky consistency.

Step 4: Add Olive Oil, Milk, Rosemary, and Salt

This is where the magic happens—the olive oil is poured in, followed by milk, a sprinkle of finely chopped fresh rosemary, and salt. These ingredients come together to create a cake that’s moist and lightly infused with piney rosemary notes that marry perfectly with chocolate. Continue folding until the batter is smooth and well combined.

Step 5: Bake Your Cake

Pour the batter into a well-greased and lined 23cm round cake tin and bake at 180°C (350°F) for 30 to 40 minutes. The cake is done when a skewer inserted in the center comes out with moist crumbs but no wet batter. Watch carefully to avoid overbaking, as this would dry out the cake.

Step 6: Brush with Syrup and Cool

As soon as the cake is out of the oven, poke several holes on top with a skewer and generously brush with at least 4 tablespoons of the reserved candied orange syrup. This step infuses the cake with extra moisture and a citrusy shine. Let the cake rest in the tin for 10 minutes, then transfer it to a wire rack to cool completely. For an even more pronounced flavor, give the cake another syrup brushing once cooled.

Step 7: Decorate with Candied Blood Oranges

Finally, arrange those stunning candied blood orange slices atop the cake, drizzle with a bit more syrup, and prepare for countless compliments. This final step not only makes the cake look absolutely gorgeous but heightens its flavor with every bite.

Garnishes

The candied blood oranges are already show-stopping, but feel free to add a few fresh rosemary sprigs or even a dusting of cocoa powder to echo the cake’s flavors. A light dusting of powdered sugar can also add a touch of visual drama and sweetness.

Side Dishes

This cake pairs beautifully with a lightly whipped cream or a scoop of vanilla bean ice cream, which offers creaminess that balances the intense chocolate and citrus elements. For an adult twist, consider serving with a small glass of ruby port or a bright citrus-infused tea to echo the lovely flavors.

Creative Ways to Present

Slice the cake into generous wedges and present on a rustic wooden board or an elegant ceramic platter. Garnish each slice with a small sprig of rosemary and a single candied orange slice for a touch of elegance. For parties, you can even serve smaller, individual mini cakes topped similarly, perfect for sharing.

Make Ahead and Storage

Storing Leftovers

This cake holds up wonderfully when covered tightly with plastic wrap or stored in an airtight container at room temperature for up to 3 days. The syrup soak ensures it stays moist and flavorful, so it’s a great choice for making ahead of time.

Freezing

If you want to save leftovers longer, wrap the cooled cake tightly in cling film and then in aluminum foil, freezing for up to 2 months. Thaw slowly in the refrigerator overnight before bringing to room temperature and refreshing with a brush of leftover syrup or a sprinkle of fresh powdered sugar.

Reheating

For a freshly baked feel, warm individual slices gently in the microwave for 15 to 20 seconds or in a low oven (150°C/300°F) for 5–10 minutes. Just be sure not to overheat, as the olive oil can sometimes cause the cake to become oily if warmed too much.

FAQs

Can I use regular oranges instead of blood oranges?

Absolutely! Regular oranges will still work beautifully in this recipe, though the vibrant color and distinct flavor of blood oranges add an extra special touch to the cake and presentation.

Is olive oil really a good substitute for butter in cake?

Yes! Olive oil keeps the cake moist and adds a subtle fruity note that enriches the flavor profile without overpowering it. Just make sure to use good quality extra virgin olive oil for the best taste.

How important is fresh rosemary in this recipe?

Fresh rosemary is essential for that fragrant herbal note that balances the sweetness and richness of the chocolate. Dried rosemary won’t provide the same delicate aroma or taste.

Can I make the candied oranges ahead of time?

Definitely. In fact, making the candied blood oranges a day or two ahead allows their flavors to deepen and makes the cake assembly easy and quick on the day you want to serve it.

What’s the best way to ensure the cake is moist?

Using olive oil instead of butter, along with brushing the cake with the reserved syrup, is key to maintaining moistness. Also, don’t overbake — check with a skewer and pull the cake out while it still has moist crumbs attached.
