Bolo de Laranja, or Brazilian orange cake, is one of the most beloved everyday cakes across Brazil, the kind of simple, comforting bake found in nearly every home kitchen and neighborhood bakery. What sets it apart from other citrus cakes is that the whole orange, peel, pith, juice, and all, is blended directly into the batter, giving the cake an intensely fragrant, deeply citrusy flavor that a splash of juice or a bit of zest alone simply cannot achieve. It’s traditionally finished with a light, tangy orange glaze or a dusting of sugar, and pairs perfectly with an afternoon coffee.
This guide covers everything you need to bake an authentic, moist Bolo de Laranja at home: the technique behind blending a whole orange into the batter, a fully tested recipe, step-by-step instructions, troubleshooting advice, delicious variations, storage tips, and answers to the most common questions bakers have about this recipe.
What Makes Bolo de Laranja Different from Other Orange Cakes?
Many orange cakes rely solely on zest and juice for flavor, which can result in a cake that tastes only mildly of citrus. Bolo de Laranja takes a different approach rooted in traditional Brazilian home baking: an entire orange, peeled of only the outermost layer of very bitter skin if needed, is blended whole, pith included, directly into the wet ingredients. The pith, which many bakers avoid because of its bitterness, actually contributes pectin and a rounder, more complex citrus flavor when balanced correctly with sugar. The result is an incredibly moist crumb with orange flavor in every single bite, not just on the surface.
Why You’ll Love This Recipe
- Uses one whole orange, meaning no wasted zest or juice and maximum citrus flavor.
- Simple pantry ingredients you likely already have on hand, aside from the orange itself.
- Comes together quickly in a blender, requiring minimal hands-on effort.
- Produces an incredibly moist, tender crumb that stays fresh for days.
- Easily topped with a simple glaze, dusting of icing sugar, or served plain.
Ingredients You’ll Need
This recipe makes one 22cm to 24cm (9-inch) bundt or ring cake, serving 10 to 12 people.
For the Cake Batter
- 1 medium orange, whole, washed well, quartered, and seeds removed – Use a thin-skinned variety if possible; if your orange has a particularly thick, bitter pith, you can remove some of the outer peel before blending.
- 4 large eggs – Provide structure and richness; they’re blended directly with the orange for a smooth batter.
- 300g (1½ cups) white sugar – Balances the tartness and bitterness of the whole blended orange.
- 120ml (½ cup) neutral vegetable oil – Keeps the cake moist for days; unlike butter, oil stays soft even when refrigerated.
- 300g (2⅓ cups) all-purpose flour – Provides the cake’s structure.
- 1 tablespoon baking powder – The primary raising agent for a light, well-risen crumb.
- Pinch of salt – Balances the sweetness and enhances all the flavors.
For the Orange Glaze (Optional but Recommended)
- 150g (1¼ cups) icing sugar, sifted
- 2 to 3 tablespoons fresh orange juice
- Zest of ½ orange, for garnish
Equipment You’ll Need
- Blender or food processor
- Large mixing bowl
- Sifter or fine-mesh sieve
- 22cm to 24cm (9-inch) bundt pan or ring cake tin
- Wire cooling rack
- Small bowl and whisk, for the glaze
Step-by-Step Instructions
Step 1: Preheat and Prepare the Pan
Preheat your oven to 180°C (350°F). Generously grease a bundt or ring cake tin with butter or oil, then dust with a light coating of flour, tapping out any excess. This step is especially important for bundt pans, which have intricate details that can cause the cake to stick if not properly greased.
Step 2: Blend the Orange, Eggs, Sugar, and Oil
Place the quartered orange (seeds removed), eggs, sugar, and oil into a blender. Blend on high speed for about 1 to 2 minutes, until completely smooth with no visible chunks of orange peel remaining. The mixture should look pale, frothy, and well combined.
Step 3: Combine the Dry Ingredients
In a large mixing bowl, sift together the flour, baking powder, and salt. Sifting helps remove any lumps and ensures the baking powder is evenly distributed throughout the batter.
Step 4: Combine Wet and Dry Ingredients
Pour the blended orange mixture into the bowl with the dry ingredients. Whisk gently until just combined and no streaks of flour remain. Avoid overmixing, as this can develop the gluten too much and result in a denser, tougher cake rather than a light, tender one.
Step 5: Pour and Bake
Pour the batter into the prepared pan, smoothing the top with a spatula. Bake for 40 to 50 minutes, or until a skewer inserted into the center comes out clean or with just a few moist crumbs attached. Baking times can vary depending on your pan’s material and your oven, so start checking around the 40-minute mark.
Step 6: Cool in the Pan
Let the cake cool in the pan for about 15 minutes before turning it out onto a wire rack. This resting period allows the structure to firm up slightly, making it much less likely to break or stick when unmolded.
Step 7: Prepare the Glaze
While the cake finishes cooling, whisk together the sifted icing sugar and orange juice in a small bowl until you have a smooth, pourable glaze. Add the juice gradually; you want a consistency that coats the back of a spoon without being too runny.
Step 8: Glaze and Serve
Once the cake has cooled almost completely, drizzle the orange glaze evenly over the top, letting it drip down the sides. Sprinkle with the reserved orange zest for a decorative finishing touch. Allow the glaze to set for about 10 minutes before slicing and serving.
Expert Tips for the Best Bolo de Laranja
- Choose a good orange: Thin-skinned varieties like navel oranges work best, as their pith is less bitter than thicker-skinned varieties.
- Blend thoroughly: Make sure there are no visible chunks of peel left in the batter, as large pieces can create bitter pockets in the finished cake.
- Don’t overbake: Because this cake is so moist, it can be easy to mistake a slightly underdone center for doneness; use the skewer test and check a few minutes early.
- Grease thoroughly if using a bundt pan: Every groove and detail of the pan needs to be coated to prevent sticking.
- Let it cool before glazing: Glazing a completely hot cake will cause the glaze to melt and slide right off instead of setting properly.
Delicious Variations to Try
- Coconut Orange Cake: Fold in 50g of desiccated coconut into the batter for a tropical twist.
- Orange and Almond Cake: Replace 50g of the flour with ground almonds for a nuttier, richer texture.
- Chocolate-Orange Cake: Add 2 tablespoons of cocoa powder to a third of the batter and swirl it through before baking for a marbled effect.
- Mini Orange Cakes: Divide the batter into a muffin tin and bake for 18 to 22 minutes for individual portions.
- Orange and Poppy Seed Cake: Fold in 2 tablespoons of poppy seeds along with the dry ingredients.
Storage Instructions
- Room temperature: Store in an airtight container or cake dome for up to 3 days. The oil in the batter helps keep the cake moist even after a few days.
- Refrigeration: Store in an airtight container for up to a week; bring to room temperature before serving for the best texture.
- Freezing: Wrap the unglazed cake tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw at room temperature and glaze just before serving.

Frequently Asked Questions
Do I really blend the whole orange, peel and all?
Yes, the whole orange, including the peel and pith, is blended into the batter after removing the seeds. This is what gives the cake its signature intense citrus flavor and moist texture.
Won’t the peel make the cake bitter?
A small amount of bitterness from the pith is actually characteristic of this cake and is balanced by the sugar in the recipe. If you’re concerned about bitterness, choose a thin-skinned orange and consider removing the very outermost layer of peel before blending.
Can I use a different citrus fruit?
Yes, this technique works well with tangerines, clementines, or a mix of orange and lemon, though the flavor and sweetness balance will vary slightly depending on the fruit used.
Why did my cake sink in the middle?
This is usually caused by underbaking, opening the oven door too early, or old baking powder. Make sure to test with a skewer before removing the cake from the oven.
Can I make this cake without a blender?
A blender or food processor is strongly recommended to fully break down the orange peel and pith. Without one, the texture of the peel will be noticeably chunky in the finished cake.
Is this cake very sweet?
Bolo de Laranja is moderately sweet, with the sugar balancing the natural tartness and bitterness of the whole orange rather than overwhelming it. The optional glaze adds an extra layer of sweetness on top.
Final Thoughts
Bolo de Laranja is the kind of cake that proves simplicity often produces the best results. With just one whole orange and a handful of pantry staples, you get a moist, deeply flavorful cake that’s equally at home on a Brazilian coffee table or your own kitchen counter. Once you taste how much brighter and more intense the citrus flavor is compared to a zest-only cake, this is likely to become a regular in your baking rotation.
