There is an understated, sophisticated romance in European olive oil cakes that sets them apart from overly sweet, frosted layer cakes. When high-percentage Dutch-process cocoa and rich dark chocolate meet cold-pressed extra virgin olive oil, the result is a cake of breathtaking decadence. The olive oil does not make the cake taste like salad dressing; instead, its fruity, peppery undertones amplify the deep cacao notes, creating an impossibly moist, tender, fudge-like crumb that stays soft for days.

Best of all, this cake is an absolute dream for the home baker. There is no butter to cream, no stand mixer required, and no multi-layered assembly or tricky frosting to manage. Whisked together in one bowl with a simple wire whisk, baked in an eight-inch cake pan, and finished with a light dusting of cocoa powder and a shower of flaky sea salt, it is an effortless showstopper for intimate dinner parties and afternoon espresso.

Why You’ll Love This Chocolate Olive Oil Cake

This elegant Italian-inspired single-layer cake will become your signature dessert:

Unrivaled Moisture: Unlike butter which solidifies at room temperature, liquid olive oil keeps the crumb intensely moist and tender for nearly a week.
Complex Chocolate Depth: The combination of Dutch cocoa, hot brewed coffee, and dark chocolate creates rich, fudge-like luxury.
Simple One-Bowl Prep: Comes together in ten minutes with a simple wire whisk—no stand mixer or electric beaters needed.
Naturally Dairy-Free Friendly: Made with pure extra virgin olive oil rather than butter, making it easy to accommodate dairy-free guests.
Refined, Adult Sophistication: Not cloying or sugary; a dusting of cocoa and flaky salt provides the perfect bittersweet finish.

Ingredients You’ll Need

Using quality extra virgin olive oil and premium Dutch cocoa is essential.

The Wet Base

Extra Virgin Olive Oil: Half a cup of high-quality fruity, cold-pressed extra virgin olive oil (plus 1 tablespoon for greasing the pan).
Hot Brewed Coffee or Boiling Water: Half a cup of freshly brewed strong coffee. (Hot coffee blooms the cocoa powder, unlocking its deepest aromatic compounds without leaving any coffee flavor!).
Large Eggs: Three large eggs, at room temperature.
Granulated White Sugar: Three-quarters of a cup.
Dark Brown Sugar: A quarter cup of packed brown sugar for moisture and toffee notes.
Pure Vanilla Extract: One tablespoon of real vanilla extract.

The Dry Ingredients

All-Purpose Flour: One cup (120g) of unbleached all-purpose flour, spooned and leveled. (Or 1:1 gluten-free baking flour).
Dutch-Process Cocoa Powder: Half a cup (about 50g) of unsweetened Dutch-process cocoa powder for intense color and smooth flavor.
Baking Powder & Baking Soda: Half a teaspoon each to give the dense cake a gentle, tender lift.
Fine Sea Salt: Half a teaspoon of salt.

Finishing

Flaky Sea Salt: Maldon sea salt flakes for sprinkling across the top.
Powdered Sugar or Extra Cocoa: For dusting before serving.

How to Make Chocolate Olive Oil Cake

Follow these culinary steps for an ultra-tender crumb and velvety texture.

Step 1: Prep and Preheat

Preheat your oven to 350°F (175°C). Grease an 8-inch or 9-inch round springform or regular cake pan with olive oil. Line the bottom with a circle of parchment paper and grease the paper lightly.

Step 2: Bloom the Cocoa Powder

In a small heatproof bowl, whisk the Dutch cocoa powder into the hot brewed coffee until completely smooth and free of lumps. Let cool for 5 minutes.

Step 3: Whisk Eggs, Sugars, and Olive Oil

In a large mixing bowl, combine the eggs, granulated sugar, and brown sugar. Whisk vigorously for 2 minutes until the mixture lightens in color and becomes slightly thickened and frothy. Slowly stream in the extra virgin olive oil while whisking continuously until emulsified. Whisk in the vanilla extract and the cooled bloomed cocoa mixture.

Step 4: Fold in Dry Ingredients

In a separate small bowl, whisk together the flour, baking powder, baking soda, and fine sea salt. Pour the dry ingredients into the wet chocolate mixture. Using a silicone spatula, gently fold together just until combined and no dry flour streaks remain. Do not overmix.

Step 5: Bake to Perfection

Pour the glossy batter into the prepared cake pan, smoothing the top with a spatula. Bake at 350°F for 30 to 35 minutes. Check with a toothpick: insert into the center—it should emerge with moist, sticky chocolate crumbs, but no wet liquid batter. Do not overbake.

Step 6: Cool and Garnish

Place the pan on a wire cooling rack and let cool for 20 minutes. Run a thin butter knife along the outer edge and invert the cake onto the rack, discarding the parchment paper. Flip right-side up and let cool completely. Dust lightly with powdered sugar or cocoa powder, and sprinkle generously with flaky sea salt. Slice and serve with fresh berries or softly whipped cream.

Tips for Chocolate Cake Mastery

Always Bloom the Cocoa: Whisking unsweetened cocoa powder into hot coffee or boiling water dissolves the cocoa solids and releases aromatic oils that dry flour mixing leaves trapped.
Choose the Right Olive Oil: Use a medium-fruity extra virgin olive oil. Avoid harsh, intensely bitter “early harvest” oils, which can overwhelm the chocolate.
Tastes Even Better the Next Day: As the cake rests overnight covered on the counter, the olive oil continues to tenderize the crumb, making it even fudgier on day two and three.
