Homemade Marble Bundt Cake
I’ve never been much of a marble cake fan. That is, until this recipe. I typically find them to be pretty dry and the chocolate portion to be a bit lacking. This marble cake, however, does not disappoint! It’s super soft, moist and buttery. Sour cream, extra butter and whole milk are added to make this cake super rich.
Marble cakes aren’t as difficult to make as they look. It’s simply a white cake batter divided with chocolate added to half then marbled together with a butter knife.
I played around with this recipe a lot. I decided to substitute the cocoa powder for semi-sweet chocolate and add more butter for a softer cake. The result was the perfect cake recipe!
Don’t Forget the Chocolate Ganache!
The chocolate ganache is optional, but highly recommended. This cake is awesome by itself or with a dusting of powdered sugar or cocoa powder, but this velvety smooth and rich chocolate ganache takes it to the next level and highlights the chocolate cake in the center without overshadowing the outer vanilla cake.
For this marble cake recipe, I used the same chocolate ganache I used on my Flourless Chocolate Cake and Cosmic Brownies. The ganache is super easy to whip up. Just chocolate and heavy cream melted and poured on top. Spread the ganache on top of the cake. Place the cake back in the fridge to set, and enjoy!
- Cake Flour: I like Bob’s Red Mill Super-Fine Cake Flour because it never fails, but use whichever you prefer.
- Baking Powder and Baking Soda: To help the marble bundt cake rise.
- Salt: Every cake (and sweet dessert, really) benefits from a little bit of salt to balance out the sweetness.
- Sour Cream and Whole Milk: This makes the cake super moist with a fine crumb. Works similar to buttermilk in some chocolate cake recipes.
- Sugar: Like most cakes, you’ll need to use white granulated instead of brown so it doesn’t weigh down the cake batter.
- Eggs: You’ll need two large eggs and one yolk for this recipe, all at room temperature.
- Vanilla: As always, opt for pure vanilla extract over imitation.
- Butter: You’ll need unsalted for this recipe to best control the amount of sodium in the cake, and make sure it’s softened to room temperature.
- Semi-Sweet Chocolate Chips: I prefer using these in my chocolate cake batter because they’re not overly sweet, but dark chocolate would also work.
- Chocolate Ganache: All you need is more semi-sweet chocolate chips and some heavy cream to make the best (and easiest) homemade chocolate ganache.
How To Make Marble Bundt Cake
You’ll find more detailed instructions on how to make this homemade marble cake in the recipe card below, but in short you essentially make vanilla cake batter and then separate it to make the chocolate cake batter by adding melted semi-sweet chocolate chips.
It’s crucial to not overmix your batter while assembling the ingredients. This ensures that the cake turns out airy, moist, and with a fine crumb.
To achieve the marbled effect when assembling the two cake batters in your bundt pan, simply spoon the vanilla cake batter into the prepared pan, then spoon the chocolate cake batter on top. Using a butter knife, swirl the two batters together in an S formation until incorporated. Bake at 350 degrees for 35-40 minutes, checking with a dry toothpick at the 30-minute mark. Allow it to cool in the pan on a wire rack for 20 minutes before flipping and dislodging from the bundt pan.
Serve with a dusting of powdered sugar or cocoa powder, or with my favorite chocolate ganache.
How To Make Homemade Chocolate Ganache
- Microwave chocolate chips and heavy cream in a medium microwave-safe bowl in 15 second intervals until fully melted.
- Allow the ganache to cool for about 2-3 minutes, and then pour and spread on top of the cake.
- Place iced cake back into the fridge to allow the ganache to set.
- It’s very important to bring all of your refrigerated ingredients to room temperature. This produces a light and airy cake.
- Do not over mix the batter. I like to fold the last bit of flour by hand with a rubber spatula.
- This cake cooks quicker if you are making it in a larger bundt pan. I like to check the cake after 35 minutes.
Storage, Freezing, and Reheating Instructions
- Store cake at room temperature in a sealed cake stand or airtight container for up to 3 days.
- Freeze cooled cake by the slice or whole wrapped in plastic wrap and in a freezer-safe plastic bag or container for up to 3 months.
- Reheat frozen cake by allowing it to come to room temperature on the counter or microwaving it for 30 seconds or more at a time until warmed through. You can also toast it in the oven at 350 for 10 minutes or so, but be careful not to dry out. Enjoy room temperature cake as is.
