Ingredients for Chocolate Orange Bundt Cake

Although it looks decadent, this cake is easy to make and uses approachable pantry ingredients.

To make the chocolate orange cake, you will need:

• Flour: All-purpose flour, sifted if possible, forms the cake base.
• Cocoa: Unsweetened baking cocoa adds the chocolate backbone; the ganache uses chopped chocolate.
• Granulated sugar: Balances the bitterness of cocoa.
• Baking soda: Reacts with the orange juice to lighten the crumb.
• Salt: A pinch enhances the chocolate flavor.
• Orange juice: Freshly squeezed is best, but concentrate works in a pinch.
• Mayonnaise: Adds moisture and richness—an old-fashioned baker’s trick.
• Vanilla: Use pure vanilla extract to deepen the flavor.
• Orange zest: Gives bursts of citrus throughout the cake.

For the chocolate ganache you will need:

• Semi-sweet chocolate: Use a high-quality bar or chips for the best ganache.
• Heavy cream: Warmed and poured over the chocolate to create a smooth glaze.
• Corn syrup: Optional, but it improves sheen and pourability.

Exact ingredient amounts and full recipe details are provided in the recipe card below.

Substitutions

• Flour: A 1:1 gluten-free flour blend can often replace all-purpose, though I haven’t tested it personally with this recipe.
• Cocoa powder: For every 3 tablespoons of cocoa, you can substitute 1 ounce unsweetened chocolate (melted) added with the wet ingredients.
• Sugar: Granular sugar substitutes such as granular monk fruit or erythritol blends may be used, adjusting to taste.
• Mayonnaise: Sour cream is a suitable alternative if preferred.

Equipment

No specialty tools are required—these common items will do the job:

• 9-inch bundt pan (or similar size)
• Mixing bowls
• Electric mixer or whisk
• Measuring cups and spoons
• Citrus juicer if you’re using fresh oranges

How to Make a Chocolate Orange Cake

Here is an overview of the process; follow the recipe card below for measurements and step-by-step details.

Preheat the oven to 350°F. Prepare your bundt pan by coating it with baking spray or softened butter, then dusting with a mixture of flour and cocoa to prevent sticking.

Whisk together the dry ingredients—flour, cocoa, sugar, baking soda and salt—in a large bowl. A large bowl is important because the batter will fizz when the orange juice is added.

With an electric mixer on low, slowly add the orange juice, mayonnaise and vanilla to the dry mix. The acid in the orange juice reacts with the baking soda and causes foaming; this is expected and creates a lighter cake.

Fold in the orange zest until evenly distributed, then pour the batter into the prepared bundt pan.

Bake for 45–55 minutes, or until a toothpick or knife inserted in the center comes out clean. Remove from the oven and allow the cake to cool completely before glazing; a warm cake can prevent the ganache from setting properly.

To make the ganache, heat the heavy cream just to boiling, then pour it over the chopped semi-sweet chocolate. Let it sit briefly, then whisk until smooth. Stir in a tablespoon of corn syrup for shine and a silkier texture if desired.

Place the cooled bundt on a cooling rack with parchment beneath to catch drips, or arrange parchment around the serving platter. Pour the ganache over the cake, letting it cascade down the sides. Finish with a sprinkle of orange zest or a few thin orange slices and fresh mint, if desired.

Storage

This cake keeps well at room temperature for about three days before it begins to dry out. For best results serve it fresh; the texture and ganache shine are at their peak the first few days. Freezing is not recommended for this particular recipe because the ganache and delicate crumb can be affected.

Expert Tips and FAQs

• Use a very large bowl because the batter will fizz when the orange juice meets baking soda.
• Coat the bundt pan with baking spray or butter, then dust with flour and cocoa to ensure a clean release.
• Place parchment under the cake when pouring the ganache to make cleanup easier.
• Check doneness with a toothpick or knife; if it comes out clean the cake is ready.
• Heat cream just to boiling for the ganache—do not overheat it.
• Garnish with fresh orange zest or slices to enhance the citrus aroma and presentation.
