Chocolate Nothing Bundt Cake Copycat Recipe: Soda-Infused Moisture and Hidden Buttermilk Secret

This Chocolate Nothing Bundt Cake copycat recipe delivers the same legendary moisture and rich chocolate flavor that made the original a bakery sensation. The secret lies in soda-infused batter and a hidden buttermilk technique that keeps every slice tender for days.

After years of perfecting this recipe, I've cracked the code for achieving that signature hole shape and velvety crumb without a single dry bite.

The key to success is balancing precise measurements with simple techniques—no fancy equipment required. You'll use a standard Bundt pan, but the real magic happens in the batter where buttermilk and soda create a light, airy texture while maintaining deep chocolate flavor.

This recipe delivers restaurant-quality results with just 15 minutes of active prep time and a 50-minute bake.

What you'll end up with is a cake so moist it practically oozes chocolate goodness, with a glossy glaze that clings perfectly to each slice. The hole in the center ensures even baking and creates that iconic presentation, while the buttermilk keeps the texture rich and tender rather than dense.

Every bite delivers that perfect balance of sweetness and cocoa depth that makes this cake legendary.

Perfect for special occasions or when you need a showstopping dessert that's easier than it looks. Once you try this copycat version, you'll never buy the original again—it's that good. Let's get baking!

Ingredients for chocolate nothing bundt cake copycat

Pantry staples meet bakery magic for this legendary copycat cake.

The cocoa powder is non-negotiable here—Dutch-processed delivers that signature velvety texture. Hershey's Special Dark or Ghirardelli are my go-tos, but any high-quality unsweetened cocoa works. The buttermilk? Store-bought is fine, but homemade (milk + vinegar) adds that extra tang. For the soda water, grab LaCroix or Spindrift—the carbonation is key for that signature lightness. Don't skimp on the chocolate chips either; Ghirardelli or Guittard melt perfectly and add pockets of gooey goodness. If you're using a glass Bundt pan, grease it well—this cake sticks to metal pans like glue.

No buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk—it's the same science. Out of cocoa powder? Melted dark chocolate at 1:1 ratio works in a pinch, but the texture won't be identical. The glaze calls for powdered sugar, but confectioners' sugar works too—just sift it first. For a richer glaze, add 1 tbsp melted butter. The secret to the hole? Use a 10-12 cup Bundt pan—smaller pans won't create that iconic shape. And if you're baking for a crowd, double the recipe—this cake reheats beautifully, so make extras.

This cake keeps for 5 days at room temperature wrapped tightly, but honestly? It disappears faster than that. For longer storage, freeze slices wrapped in plastic—they thaw in minutes and taste even better. The glaze sets quickly, so work fast when pouring it. Leftovers? Toast slices lightly to revive the texture. And if you're making this ahead for a party, bake it 2 days early—the flavors deepen as it sits.

Step-by-step instructions for chocolate nothing Bundt cake copycat recipe

Here's how to recreate that legendary soda-infused Bundt cake with perfect moisture and rich chocolate flavor.

In a stand mixer fitted with the paddle attachment, combine the 1 cup unsalted butter (cold, cubed) with both 2 cups granulated sugar and 1 cup packed brown sugar. Beat on medium speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume. You'll notice the color lighten and small bubbles form—this incorporates air that creates that signature tender crumb.

I like to scrape down the sides of the bowl every 30 seconds to ensure even mixing. The butter should be completely creamed with no visible lumps, and when you lift the paddle, the mixture should hold soft peaks. This step is critical for that melt-in-your-mouth texture that makes this cake legendary.

Reduce the mixer speed to low and gradually add the 0.75 cup natural cocoa powder. Mix just until combined, then add the 2 cups all-purpose flour, 0.5 teaspoon baking soda, and 0.5 teaspoon salt. Mix on low speed for 30-45 seconds until just incorporated—you should still see some flour streaks. Overmixing develops gluten, which can make the cake dense.

Here's the secret: sift the dry ingredients together before adding to prevent clumps. The cocoa powder should be evenly distributed but not overworked. I always use high-quality, unsweetened cocoa powder for that authentic chocolate flavor that makes this cake special.

In a separate bowl, whisk together the 1 cup buttermilk, 1 cup cold soda water, and 2 teaspoons vanilla extract. The soda water adds that signature lightness and moisture that makes this cake so uniquely tender. Gradually add this wet mixture to the dry ingredients, mixing on low speed just until combined.

Don't overmix—you're looking for a smooth, thick batter that holds its shape when dropped from a spoon. The buttermilk adds acidity that helps activate the baking soda for optimal rise. Fold in the 1.5 cups chocolate chips by hand using a silicone spatula, making sure they're evenly distributed throughout the batter.

Preheat your oven to 350°F. Generously grease and flour the 10-12 cup Bundt pan using vegetable shortening or baking spray. Pour the batter into the prepared pan and smooth the top. Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean. The cake should be springy to the touch and pull away slightly from the sides of the pan.

I've found that baking time can vary slightly based on your oven, so start checking at the 45-minute mark. The cake is done when it's set but still slightly moist in the center—it will continue cooking as it cools. Let the cake cool in the pan for 15 minutes, then invert onto a wire rack to cool completely before glazing.

While the cake cools, prepare the glaze by whisking together 2 cups powdered sugar, 0.25 cup cold heavy cream, and 2 tablespoons warm milk until smooth and glossy. The glaze should be thick enough to coat the back of a spoon but still drizzle easily. If it's too thick, add 1 teaspoon milk at a time until you reach the perfect consistency.

Once the cake is completely cool, carefully pour the glaze over the top and let it drip down the sides. The glaze should create that beautiful glossy finish that makes this cake look as good as it tastes. Allow the glaze to set for 10 minutes before slicing. Serve at room temperature for the best texture and flavor experience.

Classic Chocolate Glaze

The signature glaze is made with 2 cups powdered sugar, ¼ cup cold heavy cream, and 2 tablespoons warm milk—this creates that perfect glossy finish that makes every slice look bakery-fresh. For extra richness, I sometimes add 1 tablespoon melted butter to the glaze mixture.

The key is to whisk until smooth and let it drip naturally down the sides of the cake for that professional touch. 🍫

Creamy Vanilla Frosting

For a lighter alternative, swap the glaze for a vanilla buttercream frosting made with 1 cup softened butter, 3 cups powdered sugar, and 2 teaspoons vanilla extract. Beat until fluffy, then pipe or spread over the cooled cake.

This adds a sweet contrast to the deep chocolate flavor while keeping the texture light. I like to dust with powdered sugar for an elegant finish. 🥛

Salted Caramel Drizzle

Elevate your cake with a salted caramel drizzle—simmer ½ cup granulated sugar until amber, then whisk in ¼ cup heavy cream and 1 tablespoon butter. Finish with a pinch of flaky sea salt and drizzle over the glaze. The sweet-salty combo enhances the chocolate's richness perfectly. 💛

Espresso Glaze Boost

For coffee lovers, add 1 tablespoon instant espresso powder to the glaze mixture for a mocha-inspired twist. The espresso deepens the chocolate flavor without overpowering it. I use Starbucks Via for consistent results. This works especially well with a dark chocolate glaze variation. ☕

Peanut Butter Swirl

Create a marbled effect by swirling ½ cup creamy peanut butter into the batter before baking. After glazing, drizzle with melted peanut butter> and chopped peanuts for a nostalgic flavor combination. This adds a protein-rich element that balances the sweetness beautifully. 🥜
