This incredibly moist Italian Orange Cake is made with a whole blended orange—peel and all—and ready in under an hour. The hero moment happens when you blitz the fresh citrus with olive oil and sugar, creating a fragrant, bright orange batter that fills the kitchen with perfume. I love how the natural oils from the rind infuse every crumb with intense flavor without any bitterness.

Why This Classic Works

I used to be skeptical about blending an entire orange, pith included, into a cake batter. I assumed the white pith would make the final result unpleasantly bitter, but I was completely wrong. In the heat of the oven, the sugars and olive oil essentially “candy” the peel, leaving behind a deep, sophisticated citrus flavor that zest alone can never achieve.

This traditional Sicilian method, often called Pan d’Arancio, replaces butter with olive oil, which keeps the crumb tender for days. It is not a light, airy sponge; it is a dense, damp, and pudding-like cake that pairs perfectly with a strong morning coffee.

Italian Orange Cake Ingredients

1 whole orange (approx. 300g): Choose a thin-skinned variety like Navel or Valencia. Wash it thoroughly, slice it, and remove any seeds, but keep the peel on.
250g (1 ¼ cups) granulated sugar: You need enough sweetness to balance the tartness of the whole fruit.
3 large eggs: Use room temperature eggs for the best emulsion.
120ml (½ cup) extra virgin olive oil: A mild olive oil works best, adding moisture and a subtle savory note.
1 tsp vanilla extract: Enhances the floral notes of the citrus.
250g (2 cups) all-purpose flour: Provides the structure.
2 ½ tsp baking powder: Essential for lift, as the heavy fruit puree can weigh the batter down.
½ tsp salt: Balances the sweetness.
Powdered sugar: For dusting the finished cake.

How To Make Italian Orange Cake

Prep the Oven and Pan: Preheat your oven to 350°F (180°C). Grease a 9-inch (23cm) springform pan or round cake tin with oil and line the bottom with parchment paper.
Blend the Wet Ingredients: Wash the orange well, cut it into chunks, and discard any seeds. Place the orange chunks (peel included), sugar, eggs, olive oil, and vanilla into a blender or food processor. Blend on high until the mixture is smooth and pale orange, with only tiny flecks of peel visible.
Mix the Dry Ingredients: In a large mixing bowl, whisk together the flour, baking powder, and salt until well combined.
Combine the Batters: Pour the wet orange mixture into the bowl with the flour. Gently fold everything together with a spatula just until no streaks of flour remain. Do not overmix, or the cake may become tough.
Bake: Pour the batter into the prepared pan and smooth the top. Bake for 45 to 55 minutes. The cake is done when it is golden brown on top and a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Cool and Serve: Let the cake cool in the pan for 10 minutes, then release it from the springform ring and cool completely on a wire rack. Dust generously with powdered sugar before serving.

Recipe Tips

Tip: Choose Thin Skins. Try to find oranges with thinner skins. If your orange has a very thick, white pith, you can carefully slice a little bit of it off before blending to ensure the cake isn’t too bitter.
Tip: Don’t Skip the Seeds. Be meticulous about removing seeds from the orange chunks. Even one blended seed can add a harsh bitterness that sugar can’t hide.
Tip: Olive Oil Matters. While you can use vegetable oil, a mild extra virgin olive oil adds the authentic Italian flavor profile and keeps the texture superior.
Tip: Glazing Option. If you prefer a glaze over powdered sugar, mix 1 cup of powdered sugar with 2 tablespoons of fresh orange juice and drizzle it over the cooled cake.

What To Serve With Italian Orange Cake

This cake is traditionally served as a breakfast sweet or an afternoon tea treat rather than a heavy dessert. It pairs beautifully with a shot of hot espresso or a cappuccino, as the coffee cuts through the sweetness of the citrus.

For a more elegant dessert course, serve a slice with a dollop of unsweetened mascarpone cream or a spoonful of Greek yogurt. The creaminess balances the dense texture of the crumb.

How To Store

Because of the olive oil and whole fruit, this cake stays moist for a long time. Store it in an airtight container at room temperature for up to 3 days. It actually tastes better on the second day as the flavors meld.

You can also freeze individual slices wrapped tightly in plastic wrap and foil for up to 3 months. Thaw at room temperature for an hour before eating.

FAQs

Can I use blood oranges?
Yes, blood oranges work beautifully and give the cake a darker, moodier color. Just make sure to check for seeds, as they can be harder to spot in the dark flesh.
Why is my cake bitter?
Bitterness usually comes from seeds that were blended by accident or an orange with an exceptionally thick pith. Using a little more sugar or a simple glaze can help mask this.
Can I use almond flour?
You can substitute about 1/2 cup of the all-purpose flour with almond flour for an even moister, nuttier texture, which is very traditional in Sicilian baking.
Do I need a high-speed blender?
No, a standard food processor or regular blender works fine. You want the orange to be pureed, but small specs of peel are perfectly fine and add texture.
