Make It Your Way

One of the best parts about this Chocolate Orange Cake with Blood Orange Frosting Recipe is how adaptable it is. Feel free to tweak it to suit your taste or dietary needs — the layers of chocolate and citrus really welcome some creativity!

  • Dairy-Free Delight: Swap the unsalted butter with a rich plant-based butter and replace buttermilk with a mix of dairy-free yogurt and lemon juice. I tried this for a friend who’s dairy-free, and it was every bit as luscious and moist — seriously, zero compromises on flavor!
  • Decaf or Kid-Friendly Version: If espresso’s not your thing, or you’re baking for little ones, simply use a strong brewed decaf coffee or even cold water. I’ve done this when baking for a family gathering, and it still brought out that lovely chocolate depth.
  • Seasonal Twist: Out of blood oranges? Regular navel oranges will do nicely. The color and citrus taste won’t be quite as vivid, but the cake remains delicious and bright. Just zest and juice as usual, and you’re good to go!
  • Extra Zest & Texture: Sometimes I like to fold in chopped toasted almonds or pistachios into the batter for a bit of crunch, or sprinkle finely chopped crystallized ginger into the frosting. It adds a subtle spice and makes each bite interesting.

Step-by-Step: How I Make Chocolate Orange Cake with Blood Orange Frosting Recipe

A slice of cake with two clear layers sits on a white plate over a white marbled surface. The bottom layer is thick, dark brown, and has a moist texture. The top layer is thick with smooth, white cream. On top of the cream, there are two thin, round slices of dried citrus, one orange and one slightly darker with purple edges, overlapping each other. A small sprig of green leaves and tiny white flowers is placed next to the citrus on the cream. In the background, more cake slices can be seen on a white plate.

Step 1: Preheat and Prep Your Cake Pans

Start by bringing your kitchen to life with the smell of fresh oranges and cocoa! Preheat your oven to a steady 350°F (175°C). Grease two 8-inch round cake pans with a nice coating of butter or oil, then dust them lightly with flour or line with parchment paper—this keeps the cakes popping out perfectly without sticking.

Step 2: Whisk Together Your Dry Ingredients

In a medium bowl, sift together ⅔ cup all-purpose flour, ½ cup cocoa powder, ⅔ teaspoon baking soda, ⅓ teaspoon baking powder, and ½ teaspoon salt. Sifting is key here—it helps combine everything evenly and keeps the cake crumb light and tender.

Step 3: Mix Wet Ingredients to Silky Smoothness

Grab a large bowl and whisk ⅓ cup buttermilk, 2 tablespoons neutral oil, 1 large room temperature egg, ⅔ cup packed brown sugar, 3 tablespoons of fresh orange zest, ¼ cup melted and cooled dark chocolate, and ⅓ cup espresso or strong coffee until the mixture is silky smooth. The buttermilk and orange zest bring brightness and moisture, while the coffee deepens the chocolate flavor beautifully.

Step 4: Gently Combine Dry and Wet Mixtures

Slowly add your dry ingredients to the wet bowl, stirring gently until just combined—don’t overmix! You’ll want the batter to look slightly lumpy but cohesive, as overmixing will make the cake dense rather than delightfully tender.

Step 5: Whip the Egg Whites for Lightness

In a clean, dry bowl, beat 3 egg whites until soft peaks form. Gradually add 1 cup granulated sugar and continue beating until you get stiff, glossy peaks. This step gives the cake its airy texture, so make sure the peaks hold firm and don’t droop.

Step 6: Fold the Egg Whites Into the Batter

Gently fold the whipped egg whites into the cake batter in three additions. Use a rubber spatula and a light hand, folding carefully to keep as much air in the batter as possible—this is what makes your cake fluff up beautifully.

Step 7: Bake to Perfection

Divide the batter evenly between the two prepared pans. Pop them in your preheated oven and bake for 35 minutes. When a toothpick inserted in the center comes out clean, you know they’re done. The cake layers should spring back slightly when pressed and smell like chocolate and citrus heaven.

Step 8: Let Your Cake Layers Cool

Let the cakes cool in their pans for 10 minutes, then gently turn them out onto a wire rack to cool completely. This part takes patience but trust me — frosting warm cake will make for a melted, messy frosting job.

Step 9: Whip Up the Blood Orange Buttercream

Beat 1⅓ cups room temperature unsalted butter until creamy and pale. Slowly add ¼ cup cooled blood orange juice reduction (remember, simmer ½ cup juice until ¼ cup remains) and continue beating until light and fluffy. Fold in the zest of 2 blood oranges for that vibrant citrus pop that ties everything together.

Step 10: Assemble and Frost Your Masterpiece

Place one cake layer on your serving plate. Spread a generous layer of blood orange buttercream on top, then place the second cake layer over it. Use the remaining frosting to cover the top and sides evenly. Take your time here — smooth and even frosting is part of the charm!

Step 11: Add the Final Flourishes

Decorate with dried orange slices and fresh, organic, food-safe flowers for an eye-catching finish. This step not only adds beauty but also hints at the flavors waiting inside each slice.

Instructions

  1. Preheat Oven and Prepare Pans: Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour two 8-inch round cake pans or line them with parchment paper to prevent sticking.
  2. Mix Dry Ingredients: In a medium bowl, sift together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
  3. Combine Wet Ingredients: In a large bowl, whisk the buttermilk, neutral oil, egg, brown sugar, orange zest, melted dark chocolate, and espresso until smooth and fully combined.
  4. Incorporate Dry into Wet: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Do not overmix to keep the cake tender.
  5. Whip Egg Whites: In a separate bowl, beat the 3 egg whites until soft peaks form. Gradually add the granulated sugar and continue beating until stiff glossy peaks form.
  6. Fold Egg Whites: Gently fold the whipped egg whites into the cake batter in three additions, careful not to deflate the mixture to maintain lightness.
  7. Bake the Cake: Divide the batter evenly between the prepared pans and bake in the preheated oven for 35 minutes, or until a toothpick inserted into the center comes out clean.
  8. Cool the Cakes: Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Then turn out onto a wire rack and cool completely.
  9. Make Buttercream: In a large bowl, beat the room temperature unsalted butter until creamy and pale. Gradually add the cooled blood orange juice reduction and continue beating until light and fluffy. Fold in the zest of 2 blood oranges for extra flavor.
  10. Assemble: Place one cake layer on a serving plate, spread a generous layer of blood orange buttercream on top. Place the second layer over and frost the top and sides evenly with the remaining buttercream.
  11. Decorate: Garnish the cake with dried orange slices and fresh organic, food safe flowers for a stunning presentation.
  12. Serve: Slice the cake into 8 equal pieces and serve. Enjoy your rich, flavorful Orange Chocolate Cake with Blood Orange Buttercream Frosting!

Notes

  • If you don’t have blood oranges, regular navel oranges can be used, though the flavor and color will be less intense.
  • The espresso or strong coffee enhances the chocolate flavor but can be omitted for a milder taste.
  • Ensure egg whites are beaten to stiff peaks to help the cake achieve a light and airy texture.
  • For a dairy-free version, substitute butter with a plant-based alternative and buttermilk with a dairy-free yogurt mixed with lemon juice.
  • The blood orange juice reduction should be cooled completely before adding to buttercream to avoid melting the butter.
  • Using fresh, room temperature eggs and butter helps achieve the best texture in cakes and frostings.
