This Portuguese Orange Cake recipe is authentic + SO GOOD

This beloved orange cake recipe was shared with my by my friend who is married to a Portuguese man with a major penchant for the orange cake of his country.

It’s definitely one of the best cake recipes I’ve got and one of my favorite orange desserts.

This simple Portuguese orange cake recipe is moist and fragrant, with the most fragrant, bright orange flavour. Both the zest and juice of three oranges are involved, so it is wonderfully orange-y.

Moist Orange Cake

Why The Internet Is Obsessed with this Orange Cake

This moist orange cake recipe has been a fan favorite on the Foodess blog since I posted it a decade ago, and for good reason.

  • It’s a sponge cake of sorts, with egg whites folded in at the last minute to lighten the batter, but with more moisture than the airy sponge cakes you may have had.
  • Both the zest and juice of three oranges are used, so it is wonderfully orange-y and citrus-y.
  • It leans slightly more toward bitterness than the tartness you might expect from citrus desserts – this is owing to the lashings of zest beaten into the batter.
    • Don’t worry, it’s not bitter-bitter, just enough to be intriguing.

Bottom line? You get a moist orange cake and a fluffy, airy sponge cake vibe all in one gorgeously orange-packed bite.

Portuguese Orange Cake Ingredients

Make sure to bring all of your ingredients to room temperature before you bake – cold eggs or oranges will cause the butter to seize up. Here’s how to quickly bring ingredients to room temperature. Now grab:

  • Butter
  • Granulated Sugar
  • Large Eggs: Separate them first, with yolks adding richness and whites providing lift.
  • Orange: Zest adds a punch of flavor, while orange juice keeps everything moist. It’s a double whammy of flavor.
  • All-purpose Flour
  • Baking Powder

Grab These Tools

  • 8×8″ Baking Dish: The perfect size for this cake, ensuring even cooking.
  • Electric Mixer: Makes creaming butter and sugar, as well as whipping egg whites, a breeze.
  • Mixing Bowls
  • Whisk and Spatula
  • Zester and Juicer

You’ll also need a wire rack for cooling, and a toothpick or meat thermometer to check doneness.

How to Make Portuguese Orange Cake: An Easy Guide

Baking a Portuguese Orange Cake is a breeze with the right approach. Here’s a step-by-step guide to making this moist and flavorful cake.

Prep Work

  • Preheat the Oven: Start by heating your oven to 350ºF (180ºC). This ensures it’s at the right temperature when your cake is ready to go in.
  • Prepare the Baking Dish: Grease an 8×8″ dish or line it with parchment paper. This helps the cake come out easily after baking.

Mix the Batter

  • Cream Butter and Sugar: Use your electric mixer to beat the butter and sugar until light and fluffy. This takes about 2 minutes.
  • Add Egg Yolks and Orange: Incorporate the egg yolks one at a time, then mix in the orange zest and juice. Don’t worry if it looks curdled at first.
  • Combine Dry Ingredients: Add the flour mixture to the butter mixture and beat until just incorporated. Avoid overmixing to keep the cake light.

Fold in Egg Whites

Egg whites add airiness to the cake, giving it a wonderful texture.

  • Whip the Egg Whites: In a separate bowl, beat the egg whites to stiff peaks. This introduces air, making the cake fluffy.
  • Fold into Batter: Gently fold a third of the egg whites into the batter to lighten it. Then, carefully fold in the rest, keeping as much air as possible.

Bake and Cool

Now, into the oven it goes. The waiting is the hardest part!

  • Bake the Cake: Pour the batter into your prepared dish and bake. Check after 35 minutes, but it may need up to 45. The cake should feel springy to the touch.
  • Cool and Slice: Let the cake cool in the pan on a cooling rack before dusting with confectioners’ sugar, if using. Use a sharp knife to cut into 9 pieces.

How to Serve this Portuguese Orange Cake

whipped cream in a bowl.
  • Room Temperature is Best: For both flavor and texture and texture.
  • Dust with Powdered Sugar: Right before serving, dust with confectioners’ sugar for a sweet touch and a beautiful look.
  • Cream on the Side: Offer whipped cream or a dollop of mascarpone. Their richness contrasts beautifully with the cake’s moisture.
  • Frost it: You could also frost it with my easy frosting recipe or cream cheese frosting.

Using Other Sized Pans

Vanilla Cake in baking pans.
  • For a 9-inch round pan, the batter amount is right for a single layer.
  • I don’t recommend loaf pans for this cake. It’s too much batter for a single pan and not enough for 2 fluffy loaf cakes.
  • For a layer cake, you could try:
    • Dividing the batter evenly between two 8-inch round cake pans.
    • This will reduce the baking time, so start checking around 15 minutes.
  • Fluffy vanilla frosting or simple whipped cream would be nice to fill and ice the cake.

Always keep an eye on the oven, and use the toothpick test (or better yet, check for 190ºF on a meat thermometer) to check if the cake is ready.

Make Ahead and Storage

  • Room Temperature Storage: Keep the cooled cake in an airtight container. It stays fresh for up to 3 days on your counter.
  • Should I refrigerate? I don’t recommend storing this cake in the refrigerator. Read my article on how long cake lasts in the fridge to find out why.
  • Freezing: This cake freezes well. Wrap it tightly in plastic wrap and then in foil. Enjoy it within 3 months for the best flavor.
  • Thawing: Thaw overnight in the fridge or for a few hours on the counter. This keeps the texture nice and moist.

Portuguese Orange Cake Recipe (Moist + Fluffy!)

This from scratch, yet simple, Portuguese orange cake recipe is moist and fragrant, with the most unreal bright orange flavour. It's definitely one of the best cake recipes I've got. Similar texture to a sponge cake, but with more moisture than even the best airy cakes you may have had. Both the zest and juice of three oranges are involved, so it is wonderfully orange-y and citrus-y.
Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 1 hour
Servings: 9

Ingredients 
 

  • cup butter softened
  • 1 ¼ cups granulated sugar
  • 4 large eggs separated, room temperature
  • 3 large oranges room temperature
  • 2 cups all purpose flour
  • 1 tsp baking powder
  • Confectioners’ sugar for dusting (optional)

Instructions 

  • Preheat oven to 350ºF (180ºC). Grease an 8×8″ baking dish or line with parchment paper.
  • Beat butter and sugar on medium speed of electric mixer until light and fluffy, about 2 minutes.
    2/3 cup butter, 1 1/4 cups granulated sugar
  • Add egg yolks, one at a time, beating well after each.
    4 large eggs
  • With mixer on low speed, add the zest and juice from all three oranges. The mixture will appear curdled at first – that's ok.
    Increase mixer speed to medium and beat until it comes together, pausing to scrape down sides of bowl as needed.
    3 large oranges
  • In a separate bowl, whisk flour and baking powder. With mixer speed on low, gradually beat into the butter mixture until just incorporated.
    1 tsp baking powder, 2 cups all purpose flour
  • In another bowl, whip egg whites until stiff peaks form. Fold 1/3 of the whites into the cake batter to lighten it up, then gently fold in the rest. (Use a light hand so you don't deflate the whites.)
    4 large eggs
  • Scrape batter into prepared baking pan and bake for 35-45 minutes, until top feels springy when gently pressed and tester inserted in centre comes out clean or with just a few moist crumbs.
    Internal temperature will be 190ºF on a meat thermometer.
    Once cake is cooled, dust with confectioners' sugar, if desired.

Notes

Orange yield: The original recipe was given to me as written, for 3 large oranges, and I’ve made it dozens of time using this quantity without measuring specific quantities of juice. That tells me that the recipe is very forgiving. But as a general guideline: N
  • Zest: From three large oranges, you might get around 3 to 4 tablespoons of zest. 
  • Juice: These oranges should yield about 1 cup of juice. 
Serving: Serve with a dusting of confectioners’ sugar, a fluffy dollop of whipped cream, or a scoop of softened vanilla ice cream.
Make ahead: Store cake at room temperature, not in the fridge. Leftovers freeze well!
