Ultimate Chocolate Fudge Cake
Ingredients
- 2 cups all-purpose flour
- 1 3/4 cups granulated sugar
- 3/4 cup unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp salt
- 2 large eggs at room temperature
- 1 cup buttermilk at room temperature
- 1/2 cup vegetable oil
- 2 tsp vanilla extract
- 1 cup boiling water
- 1 cup unsalted butter softened
- 4 cups powdered sugar sifted
- 1/2 cup whole milk at room temperature
- 1 tsp vanilla extract
- 1/2 cup semisweet chocolate chips melted and cooled
Equipment
- electric mixer
- oven
- 9-inch round cake pans
- wire rack
Method
- Preheat your oven to 350°F and generously grease two 9-inch round cake pans with butter, then line the bottoms with parchment paper circles to prevent sticking.
- In a large mixing bowl, whisk together 2 cups flour, 1 3/4 cups sugar, 3/4 cup cocoa powder, 2 teaspoons baking soda, 1 teaspoon baking powder, and 1 teaspoon salt until thoroughly combined and no lumps remain.
- Add 2 eggs, 1 cup buttermilk, 1/2 cup vegetable oil, and 2 teaspoons vanilla to the dry ingredients, then beat with an electric mixer on medium speed for 2 minutes until the batter is smooth and slightly thickened.
- Carefully pour 1 cup boiling water into the batter and mix on low speed until just incorporated; the batter will be thin but should have a uniform chocolate color throughout.
- Divide the batter evenly between the prepared pans and bake for 30-35 minutes until a toothpick inserted in the center comes out clean with just a few moist crumbs attached.
- Let the cakes cool in their pans for 15 minutes, then run a knife around the edges and invert onto a wire rack to cool completely before frosting, about 1 hour.
- For the frosting, beat 1 cup softened butter with an electric mixer until creamy, then gradually add 4 cups sifted powdered sugar and beat on low speed until combined before increasing to high for 3 minutes until fluffy.
- Add 1/2 cup milk and 1 teaspoon vanilla, mixing until smooth, then fold in 1/2 cup cooled melted chocolate until fully incorporated, creating a spreadable, glossy frosting.

Private Notes
Tried this recipe?
Let us know how it was!Adapting Your Cake Gently and Mindfully
I often hear from friends who are sugar conscious or managing dietary needs, so I want to share a few gentle tweaks.
For a lower sugar version, you can replace granulated sugar with a natural sweetener like stevia or xylitol—just be sure to check conversion ratios.
Another option is using a sugar alternative in the frosting and reducing the overall portion size, which can help with glycemic control.
Remember, it’s all about finding what feels good for you and your body while still enjoying the simple pleasure of a homemade dessert.
Little Touches That Make a Big Difference
Over the years, I’ve learned a few secrets that help this cake turn out perfectly every time.
- For an even richer flavor, try swapping the semisweet chocolate chips in the frosting with dark chocolate—it deepens the taste beautifully.
- If you’re out of buttermilk, you can make a quick version by adding a tablespoon of lemon juice to regular milk and letting it sit for 5 minutes.
- Be sure to let the cakes cool completely before frosting; I know it’s tempting to rush, but this prevents the frosting from melting and keeps those layers intact.
- This cake stores wonderfully—just cover it loosely and keep it at room temperature for up to 3 days. For longer storage, you can freeze the unfrosted layers wrapped tightly in plastic.

A Lighter Take on Indulgence
Sometimes you want all the flavor with a little less richness, and I have a few cozy swaps for you.
Try using applesauce in place of half the oil for a moist chocolate cake dessert with less fat.

Common Hiccups and How to Sidestep Them
Even experienced bakers can run into little issues, so let’s walk through them together.
Overmixing the batter after adding the boiling water can make the cake tough—just stir until combined.
Using cold ingredients can lead to a dense texture; always bring your eggs, buttermilk, and butter to room temperature.
Don’t overbake! Check a few minutes early since ovens vary; the toothpick should have moist crumbs, not be clean.
If your frosting seems too thin, chill it for 10 minutes before spreading—it’ll firm up nicely.

Keeping Your Cake Fresh and Delicious
There’s something so comforting about having leftover cake waiting for you the next day.

Thaw overnight in the fridge and frost fresh for best results.

Common Questions About Your Cake
What makes a chocolate fudge cake super moist?
The combination of buttermilk, oil, and boiling water in this Ultimate Chocolate Fudge Cake recipe ensures an incredibly tender and moist crumb. The boiling water might seem unusual, but it helps bloom the cocoa powder for maximum flavor and moisture.
Can I make this cake without buttermilk?
Yes, you can create a buttermilk substitute by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk and letting it sit for 5 minutes. This will give you similar acidity and tenderness in your moist chocolate cake dessert.
How do I get a dense chocolate fudge cake texture?
For a denser texture, avoid overmixing the batter and be careful not to overbake. This easy chocolate cake baking method naturally yields a fudgy consistency, but reducing the leavening agents slightly can also help.
What’s the best way to frost a layer cake?
Make sure your cakes are completely cool before frosting. For this decadent chocolate layer cake, I like to spread a thin crumb coat first, chill for 15 minutes, then add the final layer of chocolate fudge cake ganache for a smooth finish.
