My grandmother always said that a good chocolate cake shouldn’t need a map to find the ingredients. She kept things simple, relying on what was already in the kitchen pantry to create something that felt special and honest. This Chocolate Ganache Cake is exactly that—a reliable, deep, and comforting bake that works every single time.
This recipe creates a moist, dark crumb that pairs perfectly with a silky, two-ingredient glaze. It is the kind of cake that sits happily on the counter, inviting you to take a small sliver every time you walk by. It is straightforward enough for a Tuesday afternoon but rich enough to feel like a real treat.
Honest Deliciousness
You are going to love this cake because it represents everything good about home baking. There are no fancy techniques or hard-to-find ingredients here. It is just a simple, one-bowl cake that delivers a deep chocolate flavor without any of the fuss. The texture is soft and tender, thanks to the buttermilk, and it has a wonderful weight to it that feels satisfying.
Another reason this cake is a keeper is that it actually gets better as it sits. If you bake it today and eat it tomorrow, you will find the flavors have settled and the moisture has locked in even more. It is a forgiving recipe that doesn’t demand perfection. Even if your ganache isn’t perfectly smooth, it will still taste like a dream. This is honest comfort food at its best.
I also love how quickly this comes together. When you want a chocolate fix but don’t want to spend hours in the kitchen, this is the recipe you reach for. It is a humble cake with a sophisticated finish, proving that you don’t need a lot of steps to make something truly memorable for your family.

Ingredients
- All-purpose flour
- Granulated sugar
- Dark cocoa powder
- Baking soda

- Salt
- Buttermilk
- Hot coffee or water
- Vegetable oil
- Eggs
- Vanilla
- Heavy cream
- Dark chocolate chips
Instructions
- Preheat your oven to 325 degrees F (165 degrees C) and spray an 8-inch round cake pan with non-stick spray, lining the bottom with parchment paper.
- In a mixer bowl, combine the flour, sugar, dark cocoa powder, baking soda, baking powder, and salt using the paddle attachment on low speed.
- In a separate medium bowl, whisk together the buttermilk, hot coffee (or water), vegetable oil, eggs, and vanilla.
- With the mixer on the lowest setting, slowly pour the wet ingredients into the dry mixture, scraping the sides and bottom of the bowl to ensure everything is incorporated.
- Pour the thin batter into the prepared pan and bake for 25 to 30 minutes until a toothpick inserted in the center comes out with moist crumbs.
- Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before glazing.
- Prepare the ganache by heating heavy cream until simmering, pouring it over dark chocolate chips, letting it sit for one minute, and stirring until smooth before pouring over the cake.
Notes
For the smoothest ganache, ensure your chocolate chips are at room temperature before pouring the hot cream over them. If you prefer a non-caffeinated option, decaf coffee works perfectly to bloom the cocoa powder without adding caffeine, or you can simply use boiling water to achieve a similar depth of chocolate flavor.

Simple Pantry Staples
To make this Chocolate Ganache Cake, you only need basic ingredients that you likely already have in your cupboards. We start with all-purpose flour for the structure and granulated sugar for just the right amount of sweetness. The dark cocoa powder is the star here, giving the cake its deep color and robust flavor.
- All-Purpose Flour: This provides a reliable base for the tender crumb.
- Dark Cocoa Powder: Look for a good quality dark cocoa to get that rich, almost fudge-like taste.
- Baking Soda and Powder: These are the lifters that make sure your cake isn’t too heavy.
- Buttermilk: This is my secret for a moist cake. It adds a slight tang and keeps things tender.
- Hot Coffee or Water: Using hot liquid helps ‘bloom’ the cocoa powder, which means it brings out the deepest chocolate flavor possible.
- Vegetable Oil: This keeps the cake moist for days, unlike butter which can sometimes make a cake feel dry when cold.
- Heavy Cream and Dark Chocolate Chips: These two make the simple ganache that finishes the cake beautifully.
Using room temperature eggs and buttermilk helps everything mix together without any lumps. It is these small, simple habits that lead to the best results in your kitchen.
The Simple Way
Step 1: Prep Your Space
Preheat your oven to 325 degrees F (165 degrees C). This lower temperature helps the cake bake evenly without a big dome. Take an 8-inch round cake pan and spray it with non-stick spray. Line the bottom with a circle of parchment paper and give it another light spray. This makes sure your cake comes out of the pan without any trouble.
Step 2: Mix the Dry Ingredients
In the bowl of your mixer, add the flour, sugar, dark cocoa powder, baking soda, baking powder, and salt. Use the paddle attachment on low speed just to stir them together. You want a uniform brown color throughout the bowl so there aren’t any pockets of plain flour left behind.
Step 3: Prepare the Wet Ingredients
In a separate medium bowl, whisk together the buttermilk, hot coffee (or water), oil, eggs, and vanilla. It might look a little thin, but that is exactly what we want. If you use coffee, don’t worry—the cake won’t taste like a latte; the coffee just makes the chocolate taste more like itself.
Step 4: Combine the Batters
Keep your mixer on the lowest setting and slowly pour the wet ingredients into the dry ingredients. Use a rubber spatula to scrape the bottom and sides of the bowl to make sure everything is incorporated. The batter will be quite thin, which is normal for this style of moist chocolate cake.
Step 5: Bake to Perfection
Pour the batter into your prepared pan. Place it in the center of the oven and bake for 25 to 30 minutes. You will know it is done when a toothpick inserted into the center comes out with just a few moist crumbs. Try not to overbake it, as we want to keep that tender texture.
Step 6: Cool and Glaze
Let the cake cool in the pan for about 10 minutes. This lets the structure set. Carefully turn it out onto a cooling rack to cool completely. While it cools, make the ganache by heating the cream in the microwave until it just begins to simmer, then pour it over the chocolate chips. Let it sit for a minute, then stir until it is smooth and shiny. Pour it right over the top of your cake.
Jesse’s Simple Tips
One of my favorite tricks for a better bake is using hot coffee instead of water. The heat helps the cocoa powder dissolve and release its oils, which results in a much more intense chocolate experience. If you are worried about the caffeine, decaf works just as well.
Always make sure your eggs and buttermilk are at room temperature before you start. Cold ingredients can cause the batter to break or curdle, which affects the final crumb. If you forgot to take them out of the fridge, just put the eggs in a bowl of warm water for five minutes. For a similar simple base, you can also check out my chocolate-cake-recipe which follows these same easy principles.
Lastly, let the ganache sit for about ten to fifteen minutes after mixing before you pour it. This allows it to thicken slightly so it stays on the cake rather than running straight off the sides and onto the plate.
Simple Swaps
If you want to change things up, you can easily swap the dark chocolate chips for milk chocolate in the ganache. This will make the topping sweeter and a bit lighter in color. You can also add a half teaspoon of almond extract to the batter if you like that classic cherry-chocolate flavor combination.
For those times when you need a bigger dessert, this recipe can be doubled to create a chocolate-layer-cake. Just use two pans and increase the baking time by a few minutes. You can also stir in a handful of mini chocolate chips into the batter if you want extra little bursts of chocolate in every bite. Keep it simple and use what you have on hand.
Simple Enjoyment
This cake is best served at room temperature, which allows the ganache to stay soft and the cake to remain tender. I love serving a thick slice with a cold glass of milk or a simple dollop of unsweetened whipped cream on the side. If you are feeling fancy, a few fresh raspberries or strawberries add a nice brightness to the dark chocolate.
Because this is such a rich treat, it reminds me of a classic chocolate-fudge-cake. It is the perfect end to a Sunday supper or a cozy night in. You don’t need a special occasion to enjoy a slice of comfort like this; sometimes the best reason to bake is just because it’s a weekday.
