Ingredients for Chocolate Olive Oil Cake

  • Eggs: Six large eggs provide structure and richness to this olive oil chocolate cake. Make sure to bring the eggs to room temperature before baking.
  • Chocolate: Chopped bittersweet chocolate forms the backbone of this intensely flavored chocolate cake.
  • Extra virgin olive oil: Half a cup of extra virgin olive oil adds moisture and a subtle fruity note.
  • Vanilla extract: A tablespoon of vanilla extract enhances the overall flavor of the cake.
  • Instant espresso powder: Instant espresso powder is a subtle star, helping to intensify the chocolate flavor. Here are the 10 best instant coffee powders to buy.
  • Sugar: A cup of granulated sugar sweetens the cake and helps achieve the right texture minus the need for flour.
  • Confectioners’ sugar: Powdered sugar is used as a dusting on the finished cake, adding a touch of sweetness and a decorative finish.
  • Optional toppings: Vanilla ice cream, mixed fresh berries and whipped cream are all optional but enhance the decadent chocolate olive oil cake with lighter textures.

Directions

Step 1: Prepare the pan

Preheat the oven to 350°F. Prepare a 9 inch springform pan by coating the bottom with cooking spray and lining it with parchment paper. Secure the springform ring on top and lock it in place.

Step 2: Melt the chocolate

Place egg whites in a clean bowl and let them stand while melting chocolate. In a double boiler or metal bowl over simmering water, melt the chopped bittersweet chocolate with the olive oil. Stir until smooth. Remove from heat and stir in the vanilla extract and instant espresso powder. Set aside to cool slightly.

Step 3: Beat the egg whites

In a clean bowl, beat the egg whites on high speed until soft peaks form. Gradually add 1/2 cup of sugar while continuing to beat until stiff peaks form.

Editor’s Tip: Make sure your bowl and beaters are completely clean and free of any grease for the best results.

Step 4: Combine the ingredients

Beat the remaining 1/2 cup of sugar into the chocolate mixture. Add the egg yolks one at a time, mixing until combined. Gently fold in the egg whites, starting with a quarter of the mixture to lighten the batter and folding in the rest.

Editor’s Tip: Be very gentle when folding in the egg whites to maintain the airiness of the batter.

Step 5: Bake the cake

Transfer the batter to the prepared pan. Bake in for 25 to 30 minutes, until the cake is puffed and set. Let the cake cool in the pan for 10 minutes.

Step 6: Serve and garnish

Dust the cooled cake with confectioners’ sugar. Serve with optional toppings like vanilla ice cream, mixed fresh berries or whipped cream if desired.

Recipe Variations

  • Add a citrus twist: Add the zest of one orange to the batter for a bright, citrusy and chocolate flavor.
  • Spice it up: Mix in a pinch of cinnamon or cayenne pepper for a spicy kick to the chocolate olive oil cake.
  • Make it nutty: Fold in chopped nuts like almonds, pecans or hazelnuts for added crunch. To further enhance the flavor, make sure to toast the nuts before adding them to the batter.
  • Top with ganache: Pour a rich chocolate ganache over the cooled cake for an extra layer of decadence.
  • Add a peanut butter swirl: Swirl in 1/4 cup of peanut butter to the batter before baking for a fun visual twist.

Chocolate Olive Oil Cake Tips

What kind of pan can you use if you don’t have a springform pan?

No springform? No problem! This cake can easily be made in a 9-in. round cake pan. Grease the pan, then line the bottom with a round piece of parchment paper. Grease the parchment paper, too. After baking, let the cake cool for 30 minutes. Place a cooling rack on top of the cake, then invert so the rack is on the bottom. Gently lift pan off the cake. Peel away the parchment paper and then flip the cake back over.

What’s the best chocolate to use for chocolate olive oil cake?

Use high-quality bittersweet chocolate with approximately 60 to 70% cocoa content. This will give your cake a rich and decadent chocolate taste.
