Citrus Olive Oil Cake Built for Beach Mornings
Citrus olive oil cake is dense enough to survive a tote bag, a car floor, and three hours of sun without turning into crumbs and regret. The olive oil keeps the crumb moist for days and carries the citrus in a way that tastes almost savory, making this the cake you make Thursday night for a Saturday sunrise swim.
Ingredients
- 1 3/4 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon baking soda
- 3/4 teaspoon fine sea salt
- 3 large eggs, room temperature
- 1 cup granulated sugar
- 2 tablespoons orange zest (about 2 oranges)
- 1 tablespoon lemon zest (about 1 lemon)
- 3/4 cup extra virgin olive oil (mid-grade, fruity)
- 1/2 cup fresh orange juice
- 2 tablespoons fresh lemon juice
- 1/2 cup whole milk
- 1 teaspoon vanilla extract
- 2 tablespoons turbinado sugar, for topping
Instructions
- Preheat oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment.
- Whisk flour, baking powder, baking soda, and salt in a medium bowl. Set aside.
- In a large bowl, whisk eggs and granulated sugar until pale and slightly thickened, about 2 minutes.
- Add orange zest and lemon zest to the egg mixture and whisk to combine.
- Slowly stream in the olive oil while whisking constantly, until fully incorporated.
- Whisk in orange juice, lemon juice, milk, and vanilla.
- Fold the dry ingredients into the wet mixture in two additions, mixing just until no flour streaks remain. Do not overmix.
- Pour batter into the prepared pan and smooth the top. Sprinkle turbinado sugar evenly over the surface.
- Bake 42 to 48 minutes, until a toothpick inserted in the center comes out clean and the top is deep golden.
- Cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.
Cook’s Notes
Zest the citrus before you juice it — skipping this step is the most common mistake people make with this cake. Use room temperature eggs, since cold eggs won’t emulsify properly with the oil and can leave a greasy layer at the bottom of the pan, and let the cake cool fully before wrapping so trapped steam doesn’t turn the crust soggy by the time you unpack it at the beach.
Ingredient Swaps
Swap the lemon for grapefruit or blood orange if you want a different citrus personality, just keep the total zest and juice amounts the same for balance. Stick to a fruity, mid-grade olive oil rather than your good finishing bottle — you want body and moisture here, not bitterness.
Serving Suggestions
Wrap the whole cake and slice it once you’re actually at the beach so the cut edges don’t dry out in the wind — this is a hands, standing-up, barefoot kind of cake, best eaten plain or with a pinch of flaky salt on top.
Storage & Reheating
Wrap in parchment first, then foil, and it keeps at room temperature for about two days, even longer if the weather stays cool. No refrigeration needed, which makes it an easy make-ahead for early mornings on the sand.
Common Questions
Can I make this cake the night before?
Yes, and it’s actually better that way — the flavor settles and the crumb firms up just enough to slice cleanly the next morning.
Does this cake need to be refrigerated?
No, thanks to the olive oil it stays soft and moist at room temperature for about two days, so it’s fine to pack in a tote or basket without ice.
Why do the eggs need to be room temperature?
Cold eggs won’t emulsify properly with the olive oil, which can leave a greasy layer at the bottom of the cake instead of a smooth, even crumb.
