How to Make Dark Chocolate Blood Orange Cake

  1. Simmer the Oranges: In a large shallow saucepan, bring water to a gentle simmer. Add sugar and dissolve completely, then add sliced oranges. Simmer for 15 minutes, flip the slices, and simmer for another 15 minutes until tender. Remove oranges and cool on a drying rack.

  2. Preheat and Prepare: Preheat your oven to 350°F (177°C) for convection (or 325°F/162°C for conventional). Grease four 6-inch cake pans (or two 8-inch pans) to ensure easy release. Grate the zest from 5 blood oranges, reserving 3 for the buttercream.

  3. Juice the Blood Oranges: Juice the 5 blood oranges using a citrus juicer. Reserve 1/4 cup of juice for the buttercream, and mix 3/4 cup with the olive oil and zest for your batter.

  4. Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, salt, and baking soda until well combined. Fold in the olive oil mixture and water until smooth.

  5. Bake the Cake: Divide the batter evenly among the prepared pans and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.

  6. Make the Buttercream: In a stand mixer, beat the butter with the reserved blood orange zest until pale and fluffy. Gradually add half of the powdered sugar, mixing until incorporated, then add the remaining sugar and beat for 5-10 minutes until smooth.

  7. Incorporate Flavor: With the mixer on low-medium speed, slowly pour in the vanilla and blood orange juice, mixing until fully combined and creamy.

  8. Prepare the Ganache: Place dark chocolate in a medium bowl. In a saucepan or microwave, heat the half and half until bubbling, then pour it over the chocolate. Let sit for 1 minute, then stir until smooth.

  9. Cool the Ganache: Allow the ganache to cool for 5-10 minutes before pouring it over the cake for delicious drips. If it cools too much, microwave it for 10 seconds and stir to reconstitute.

  10. Layer and Frost the Cake: Begin with the first cake layer on a flat surface, evenly spreading about 1/4 of the buttercream on top. Repeat with the remaining layers, using leftover buttercream to frost the outside. If the cake feels unsteady, refrigerate for 15-30 minutes to set. Finally, refrigerate for an additional 30 minutes before pouring the chocolate ganache on top, letting it set for another 15 minutes. Garnish with candied orange slices if desired.

Optional: Top with candied orange slices for an elegant finishing touch.

Make Ahead Options

These Dark Chocolate Blood Orange Cake preparations are a dream for busy home cooks! You can prepare the cake layers up to 3 days in advance; just allow them to cool completely before wrapping tightly in plastic wrap and refrigerating to maintain moisture. The buttercream can be made ahead as well and stored in an airtight container in the fridge for up to 2 days—just give it a quick whip before you’re ready to frost. For the ganache, you can also make it ahead and warm it up gently before pouring on the cake. When you’re ready to serve, simply layer and frost the cake, chill it briefly to set, and decorate with candied orange slices for a wow factor with minimal last-minute effort!

Expert Tips for Dark Chocolate Blood Orange Cake

  • Use Room Temperature Ingredients: Ensure your butter, eggs, and other ingredients are at room temperature for a smoother batter that mixes easily.

  • Don’t Overmix: When combining the batter, fold gently to maintain the cake’s lightness. Overmixing can lead to a dense texture in your Dark Chocolate Blood Orange Cake.

  • Check for Doneness: Use a toothpick to test the cakes for doneness; it should come out clean or with a few moist crumbs, not wet batter.

  • Chill Between Layers: If the cake layers feel wobbly when stacking, refrigerate them for 15-30 minutes to stabilize and make frosting easier.

  • Adjust Ganache Consistency: If your chocolate ganache cools too much and thickens, microwave it in short bursts (10 seconds) and stir until it’s pourable again.

  • Store Properly: To keep your cake moist, cover it well with plastic wrap or store in an airtight container at room temperature for up to 2 days.

How to Store and Freeze Dark Chocolate Blood Orange Cake

Room Temperature: Keep the cake at room temperature for up to 2 days. Wrap it in plastic wrap to maintain moisture and freshness.

Fridge: If you have leftover cake, store it in the fridge, covered tightly with plastic wrap or in an airtight container, for up to 5 days to enhance the flavor.

Freezer: For longer storage, freeze individual slices wrapped in plastic wrap and aluminum foil for up to 3 months. Thaw in the fridge overnight before enjoying.

Reheating: To revive the cake, gently warm slices in the microwave for 10-15 seconds or serve at room temperature for the best flavor experience.

Dark Chocolate Blood Orange Cake Recipe FAQs

What is the best way to select ripe blood oranges?
Absolutely! When choosing blood oranges, look for those that are firm and heavy for their size. Their skin should be vibrant with a few dark spots indicating ripeness. Avoid any that have soft or shriveled skin.

How should I store leftover Dark Chocolate Blood Orange Cake?
Very! Keep your cake covered tightly with plastic wrap at room temperature for up to 2 days. For longer storage, place it in the fridge for up to 5 days in an airtight container. This will actually deepen the cake’s flavors, making it taste even better!

Can I freeze my Dark Chocolate Blood Orange Cake?
Of course! To freeze, cut the cake into individual slices and wrap each piece tightly in plastic wrap, followed by aluminum foil. This keeps the cake fresh for up to 3 months. When you’re ready to enjoy, simply thaw in the fridge overnight.

What should I do if my cake doesn’t rise properly?
Don’t worry! If your cake doesn’t rise, this could be due to expired baking soda, so always check that first. Also, ensure that you don’t overmix your batter, as this can lead to a dense texture. If you run into any issues, try checking your oven’s temperature with an oven thermometer to ensure it’s accurate.

Is there a dairy-free option for the frosting?
Absolutely! You can substitute the unsalted butter with a dairy-free alternative, such as coconut cream or a plant-based butter. Be sure to adjust the powdered sugar accordingly, as dairy-free butters can sometimes be softer. This will still give you a creamy texture without compromising the delectable flavor!

Are blood oranges safe for pets?
Very! While blood oranges are non-toxic to dogs and cats, the high acidity may upset their stomachs in larger quantities. Always consult with your veterinarian if you have concerns, especially regarding your pet’s dietary needs.
