The pairing of chocolate and orange is timeless—bright citrus notes lift the deep, comforting flavor of chocolate. This Orange Chocolate Buttermilk Bundt Cake combines those flavors into a rich, tender cake finished with a bright orange glaze. It’s beautifully showy thanks to the bundt shape and makes an excellent choice for family gatherings, potlucks, birthdays, or a relaxed afternoon treat.
Bundt pans create an automatic centerpiece: the molded design turns a simple cake into something special without extra decorating. For this recipe, the texture is moist and substantial, so take a few extra care steps while mixing and baking to ensure even results.
A thick batter benefits from thorough scraping of the bowl and beater so no pockets of flour or other ingredients remain unmixed. The addition of buttermilk keeps the crumb tender and helps balance the sweetness of the glaze. When pouring the batter into the pan, rotate the pan as you pour so the batter settles evenly, then run a spatula or knife through the top to release trapped air bubbles.
The orange glaze brightens each bite with fresh citrus flavor and a silky finish. Using a touch of buttermilk in the glaze cuts the sweetness slightly and delivers a more complex, balanced topping. If you like a stronger orange presence, a few drops of concentrated orange oil or extract will intensify the flavor—use sparingly, since these are potent.
A key detail with bundt cakes is greasing the pan well. Thoroughly coat every ridge and crevice so the cake releases cleanly. If a small section sticks, you can often patch it and the glaze will disguise any minor imperfections. Some bundt designs also make cutting even slices easier, which is handy for serving a crowd.
Oven temperatures vary, so treat the recommended bake time as a guideline. Pay attention to the cake’s aroma and appearance—if your oven runs hot, it may finish sooner than expected. The cake is done when it pulls slightly away from the pan, springs back lightly to the touch, and a toothpick inserted in the center comes out with a few moist crumbs.
Serve this cake to finish a dinner, to enjoy with coffee or tea, or to share with kids after school alongside a glass of milk. It’s a crowd-pleaser that looks elegant but is straightforward to bake.
Ingredients needed for Orange Chocolate Buttermilk Bundt Cake:
- Cake: all-purpose flour (or a gluten-free all-purpose blend), unsweetened cocoa powder, baking powder, baking soda, kosher salt, orange zest, granulated sugar, butter, eggs, vegetable oil, vanilla extract, optional orange oil, buttermilk
- Glaze: butter, confectioners’ sugar, buttermilk, orange zest, freshly squeezed orange juice, vanilla
PRO Tip:
Only fill the bundt pan to about two-thirds full to allow room for the cake to rise. If you have extra batter, bake it in a smaller pan—but remember smaller cakes finish baking more quickly, so watch them closely.
How to make Orange Chocolate Buttermilk Bundt Cake:
- Preheat the oven to 350°F (180°C). Grease the bundt pan thoroughly, making sure every nook is coated. Set aside.
- Make the dry mix: Whisk together the flour, cocoa powder, baking powder, baking soda, and salt in a medium bowl and set aside.
- Cream the butter, sugar, and orange zest for 2–3 minutes until light and combined. Beat in the eggs, one at a time, then add the oil and vanilla. With the mixer on low, slowly add the buttermilk.
- Add the dry ingredients in two additions, mixing on low between each until smooth and creamy. Scrape the bowl and beater to ensure everything is incorporated.
- Bake: Pour the batter into the prepared bundt pan, smooth the top, and bake 45–60 minutes, until the cake pulls away from the sides and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool the cake in the pan on a wire rack for 15–20 minutes before inverting onto the rack. Let cool completely before glazing.
- Make the glaze: Combine the butter, confectioners’ sugar, buttermilk, orange zest, orange juice, and vanilla. Whisk until smooth, adding more sugar to thicken or a little more juice to thin as needed.
- Drizzle the glaze over the cooled cake, allowing it to drip down the sides. Let the glaze set before slicing and serving.
PRO Tip:
For a more pronounced orange aroma, add a few drops of concentrated orange oil or extract. These are strong—start with a very small amount and adjust to taste.

Gluten-Free Tips:
To convert recipes to gluten-free, weigh your flour for accuracy. A commonly used conversion is about 120 grams per cup for many gluten-free blends, but different blends vary—whisk the mix, spoon it into a cup, level it, and weigh so you know the exact weight per cup for your blend. Commercial gluten-free blends can work well; check product labels to confirm ingredients remain suitable for your needs. Using a digital scale and grams will give you the most consistent results.
