Ingredients
For the Orange Walnut Cake
- 3 eggs
- 150 g sugar (¾ cup)
- A pinch of salt
- A dash of vanilla
- 130 ml vegetable oil (½ cup + 1 tablespoon)
- 150 ml fresh orange juice (½ cup + 2 tablespoons)
- Zest of 1 orange
- 300 g flour (2⅓ cups)
- 15 g baking powder
- 30 g walnuts
How to Make Easy Orange Walnut Cake
1. Preheat the Oven
Preheat your oven to 180°C (356°F).
Prepare a 24 cm baking dish by lightly greasing it or lining it with parchment paper as appropriate.
Set the prepared dish aside while you make the orange cake batter.
2. Prepare the Orange
Wash and dry a fresh orange thoroughly.
Finely grate the outer peel to obtain the zest of 1 orange.
When zesting, remove only the colored outer layer and avoid the bitter white pith underneath.
Squeeze enough fresh orange juice to measure 150 ml (½ cup + 2 tablespoons).
Set both the zest and juice aside.
3. Prepare the Walnuts
Measure 30 g walnuts.
Roughly chop them into small pieces so they can be distributed throughout the cake.
Avoid chopping them too finely if you want little pieces of walnut to remain noticeable in the finished cake.
4. Mix the Eggs and Sugar
Crack 3 eggs into a large mixing bowl.
Add 150 g (¾ cup) sugar, a pinch of salt, and a dash of vanilla.
Whisk until everything is thoroughly combined and the mixture becomes smooth and slightly lighter in color.
5. Add the Vegetable Oil
Pour in 130 ml (½ cup + 1 tablespoon) vegetable oil.
Continue whisking until the oil is fully incorporated into the egg mixture.
The vegetable oil helps give the cake its moist and tender texture.
6. Add the Orange Juice
Pour in 150 ml (½ cup + 2 tablespoons) fresh orange juice.
Mix gently until evenly combined.
Fresh orange juice provides both moisture and a bright citrus flavor.
7. Add the Orange Zest
Add the zest of 1 orange.
Stir until the zest is evenly distributed throughout the wet mixture.
Using both fresh orange juice and zest gives the finished cake a fuller, more aromatic orange flavor.
8. Add the Flour and Baking Powder
Combine 300 g (2⅓ cups) flour with 15 g baking powder.
Gradually add the dry ingredients to the wet mixture.
Gently mix until a smooth batter forms and there are no visible pockets of dry flour.
Avoid overmixing once the flour has been added. Mix only until everything is incorporated.
9. Add the Walnuts
Add the 30 g chopped walnuts to the prepared orange batter.
Gently fold them through the mixture until evenly distributed.
If desired, you can reserve a small amount of the walnuts for the surface before baking.
10. Transfer to the Baking Dish
Pour the batter into the prepared 24 cm baking dish.
Use a spatula to spread the batter evenly and smooth the surface.
If you reserved some chopped walnuts, sprinkle them over the top.
11. Bake
Place the cake in the preheated oven.
Bake at 180°C (356°F) for approximately 35–40 minutes.
The cake should rise and develop a beautifully golden surface while remaining soft inside.
To check for doneness, insert a toothpick or wooden skewer into the center.
It should come out clean or with only a few moist crumbs attached.
Since ovens can vary, begin checking around the 35-minute mark.
12. Cool the Cake
Remove the orange walnut cake from the oven.
Allow it to cool in the baking dish for a while before attempting to remove it.
Once the cake has cooled enough to handle, carefully transfer it to a serving plate or cooling rack.
13. Slice and Serve
Allow the cake to cool to your preferred serving temperature.
Slice and enjoy on its own or serve alongside your favorite coffee or tea.
The combination of soft orange cake and crunchy walnut pieces makes every slice simple but flavorful.
Tips for the Best Orange Walnut Cake
Use freshly squeezed orange juice: Fresh juice provides a brighter and more natural citrus flavor.
Use the entire orange zest: The recipe calls for the zest of 1 orange, which gives the cake its aromatic citrus character.
Avoid the white pith: Only grate the colored outer layer of the orange peel.
Chop the walnuts: Smaller pieces distribute more evenly throughout the batter.
Don’t overmix: Once the flour is added, mix only until the batter becomes smooth.
Use the correct baking dish: A 24 cm baking dish helps produce the intended cake thickness.
Preheat the oven: Place the cake into an oven already heated to 180°C (356°F).
Check after 35 minutes: Baking times vary slightly between ovens, so test the center before extending the baking time.
Why You’ll Love This Recipe
This orange cake uses a simple combination of everyday ingredients but delivers plenty of flavor.
Fresh citrus comes from both 150 ml orange juice and the zest of 1 whole orange, giving the cake a naturally fresh aroma.
The 130 ml vegetable oil helps maintain a moist, tender crumb, while 30 g walnuts provide a contrasting crunch and nutty flavor.
Another advantage is the short preparation time. The basic batter can be put together in approximately 5 minutes before the cake goes into the oven.
That makes it an excellent option when you want a homemade cake without spending a long time preparing complicated fillings, frostings, or decorations.
Why Use Both Orange Juice and Zest?
Fresh orange juice and orange zest play different roles in the recipe.
The 150 ml orange juice provides moisture, acidity, and fresh citrus flavor.
The zest of 1 orange contains aromatic oils that give the cake a stronger orange fragrance.
Together, they create a much more noticeable fresh-orange character in the finished cake.

How to Store Orange Walnut Cake
Allow the cake to cool completely before storing.
