Baking Supplies

Orange zest, flour, orange juice, eggs, oil, sugar, flour and vanilla in small bowls.

Shopping List and Ingredient Notes

This cake is made with simple ingredients at your local grocery store.

Granulated Sugar – We use white sugar to sweeten this cake. You can also use monk fruit sweetener if you prefer a healthier option.

All-Purpose Flour – This is the best flour for this recipe. You can also use whole wheat or gluten-free 1:1 baking flour. Measure the flour correctly when baking.

Unsweetened Cocoa Powder – We prefer the classic Hershey cocoa powder for this cake. You can use any unsweetened cocoa powder you like.

Baking Soda and Baking Powder are essential for making the cake light and fluffy as they act as leavening agents.

Salt – A pinch of salt will enhance the flavor and balance the sweetness.

Eggs – Use large organic eggs when making this cake.

Whole Milk – We prefer to use whole milk in this recipe, but you can also use 2% if that’s what you have.

Vegetable Oil – We prefer vegetable oil for this cake as it creates a moist and dense texture. You can also use canola oil too. Coconut oil would also work. However, it would change the flavor of the cake.

Vanilla Extract – Use pure vanilla extract for best results.

Boiling Hot Water – This will help to create a richer, more intense chocolate flavor.

Orange Juice and Zest – This recipe will need the whole orange! I use fresh orange juice and zest to create a natural orange flavor. Both of these combined give the cake an incredible orange flavor. If blood oranges are in season, you can use these too!

Sour Cream Orange Buttercream

I’ve altered my favorite sour cream chocolate frosting for this cake! The recipe is cut in half, and we have added 2 tbsp of orange zest and 1 tbsp of orange juice. It goes so well with this cake! You can also make a classic buttercream frosting and add orange juice and zest.

There are several ways you can garnish this cake with oranges:

  2. Dehydrated Oranges are great for decorating the cake and look beautiful layered over the chocolate frosting.
  3. Fresh Oranges – You can use freshly sliced oranges to decorate the cake. We recommend patting them down first to remove some of the juice.
  4. Orange Zest – This has the most delicious flavor and fragrance. It also looks beautiful on the cake!

  • Pour into an electric mixer with the whisk attachment on low speed.

Eden’s Tips
Use whole, organic ingredients when possible. It does make a difference in the flavor and outcome of the cake.
Oil and grease your pans well; use parchment paper for easy removal.
Mix well, but don’t overmix. Keep the mixer on low most of the time, and scrape the bottom and sides of the bowl.
If you want to make a dark chocolate orange cake, use Hershey’s special dark cocoa powder. If the chocolate powder has clumps, sift it into the flour using a sieve.
Baking times will vary, so set your timer for 10 minutes less and check the cake.

Frequently Asked Questions

Do chocolate and orange go together?

Chocolate and orange are a match made in flavor heaven. This timeless pairing marries chocolate’s rich, indulgent taste with orange’s bright, tangy essence, elevating simple desserts into culinary delights. 

 What’s the secret to a moist cake? 

The secret to a moist cake is the ratio of the dry and wet ingredients. Other things help, such as oil, eggs, and boiling water. The boiling water will help the chocolate bloom and create a rich flavor and moist texture.

Can I use an alternative to orange juice and zest? 

We prefer fresh orange juice and a lot of orange zest for this recipe. However, you can also use the orange extract for a subtle flavor.

 Can I make this cake ahead of time? 

This cake can be made ahead of time. Prepare the cake according to instructions and allow it to cool completely before wrapping it tightly in plastic wrap and refrigerating for up to 3 days. You can freeze the cake for up to 3 months; ensure it’s completely sealed in an airtight container or wrap.

Why is my chocolate orange cake dry?

One of the main reasons for a dry chocolate orange cake is over-baking. Pay attention to the baking time and leave it in the oven briefly. Another factor that can contribute to a dry cake is the recipe itself. A good chocolate orange cake recipe should have enough sugar for moisture and a tenderizing agent like milk, oil, and eggs. Fortunately, my recipe has all these components, ensuring your cake turns moist and delicious.
