- Baking powder (1 teaspoon): Helps the cake rise beautifully, keeping it fluffy.
- Baking soda (½ teaspoon): Works with the acids to create the perfect texture.
- Salt (½ teaspoon): Enhances all the flavors without making it salty.
- Unsalted butter, softened (½ cup): Adds moisture and richness for an indulgent crumb.
- Large eggs (2): Bind everything together while adding structure.

How to Make Chocolate-Vanilla Swirl Bundt Cake Recipe
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 350°F (175°C). This step is important so your cake bakes evenly right from the start. Next, grease and flour your bundt pan thoroughly; this ensures your cake releases effortlessly once baked, preserving that beautiful swirl design.
Step 2: Combine Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt. This dry mix is your foundation — evenly blending these ensures every bite of your cake is balanced in flavor and texture.
Step 3: Cream Butter and Eggs
Using an electric mixer, beat the softened butter until it becomes creamy and light. Then, add the eggs one at a time, beating well after each addition to incorporate air and create a fluffy batter. Stir in the vanilla extract here too, to infuse that lovely scent throughout the cake.
Step 4: Alternate Adding Dry Ingredients and Buttermilk
To keep the batter tender and moist, you’ll add the dry ingredients and buttermilk alternately to the butter mixture, beginning and ending with the dry. Mix just until combined — overmixing can make the cake dense, and we want this one to be light and airy.
Step 5: Separate and Flavor the Batters
Divide the batter evenly into two bowls. To the first bowl, add the boiling water and stir until smooth — this becomes your chocolate batter, rich and luscious. To the second bowl, combine the vegetable oil and apple cider vinegar; this forms the vanilla batter, soft and tender, ready to contrast beautifully with the chocolate.
Step 6: Create the Swirl
Begin spooning the chocolate batter into your prepared bundt pan, followed by the vanilla batter. Alternate spoonfuls to layer the batters. Then, take a knife or skewer and gently swirl through both batters to create that signature marbled effect. This is where the magic happens — every swirl is unique!
Step 7: Bake to Perfection
Place the bundt pan in the oven and bake for 40 to 45 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean. The cake’s aroma will fill your kitchen with irresistible notes of chocolate and vanilla, signaling that your masterpiece is nearly ready.
Step 8: Cool and Remove from Pan
Let the cake cool in the pan for about 10 minutes — this resting time helps it firm up just enough so you can remove it without breaking. After that, carefully invert the cake onto a wire rack to cool completely; this lets the surface set and keeps your swirl pattern flawless.
How to Serve Chocolate-Vanilla Swirl Bundt Cake Recipe

Garnishes
This cake shines wonderfully on its own, but you can add a personal touch with delicious garnishes. Sprinkle powdered sugar lightly over the top for a simple, elegant finish or drizzle with a bit of chocolate ganache to intensify the cocoa flavor. Fresh berries or a dollop of whipped cream make lovely complements that brighten every bite.
Side Dishes
Pair your Chocolate-Vanilla Swirl Bundt Cake Recipe with a scoop of vanilla ice cream or creamy mascarpone cheese for a delightful contrast in temperature and texture. A hot cup of coffee or fragrant tea is also a perfect companion, making this dessert the highlight of any gathering or cozy afternoon.
Creative Ways to Present
For a special occasion, dust edible gold flakes or place edible flowers around the cake for a stunning visual appeal. Alternatively, slice the cake into neat wedges and serve on colorful plates with a drizzle of caramel or raspberry sauce to add a pop of color and extra sweetness. Presentation can be as creative as you want, and this bundt cake welcomes it all.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, no worries — this cake keeps beautifully. Store it in an airtight container at room temperature for up to three days, making sure it’s well covered to stay moist and fresh. Avoid leaving it out uncovered, as the crumb can dry out quickly.
Freezing
Want to enjoy this delicious Chocolate-Vanilla Swirl Bundt Cake Recipe later? Wrap the cooled cake tightly in plastic wrap, then in aluminum foil and freeze for up to two months. When you’re ready to indulge again, simply thaw overnight in the refrigerator and bring to room temperature before serving.
Reheating
To revive the cake’s moist texture after refrigeration or freezing, warm individual slices in the microwave for about 15 seconds. This quick touch softens the crumb and enhances the flavors, making each bite taste freshly baked and utterly irresistible.
FAQs
Can I use regular milk instead of buttermilk?
Yes! If you don’t have buttermilk on hand, mix 1 tablespoon of lemon juice or white vinegar with 1 cup of milk and let it sit for 5 minutes before using. This homemade substitute simulates the acidity needed for the perfect texture and flavor in the cake.
Can I make this cake gluten-free?
Absolutely, but use a gluten-free all-purpose flour blend that includes xanthan gum to help with binding. Keep in mind, texture may vary slightly, but you’ll still have a delicious Chocolate-Vanilla Swirl Bundt Cake Recipe to enjoy.
What type of cocoa powder is best?
A good-quality unsweetened cocoa powder with a robust chocolate flavor works best. Avoid natural and Dutch-processed cocoa swaps unless you adjust the recipe’s leavening agents, as different cocoa powders react differently with baking soda and powder.
Can I add nuts or chocolate chips?
Definitely! Chopped walnuts, pecans, or mini chocolate chips folded into the batter add wonderful texture and bursts of flavor. Just be sure to distribute them evenly before layering your batters for the swirl effect.
How long will the cake stay fresh?
When properly stored, this bundt cake stays fresh and moist for up to three days at room temperature. For longer storage, freezing is best to preserve its delightful flavors and texture.
