Easy Chocolate Ganache Cake: Perfect in 5 Simple Steps

Chocolate ganache cake was the birthday move I made last year when I wanted something dramatic but didn’t want to spend the whole day frosting like I was auditioning for a baking show. I carried that chocolate ganache cake to the table with my best “oh this old thing?” face, even though I’d been peeking through the oven door like a nervous raccoon for 30 minutes.

Here’s what happened: the first slice came out clean, the ganache was glossy like a fancy shoe, and everyone went quiet for that first bite. Then someone asked where I “ordered it from.” That’s the sweet spot, right? Something that looks bakery-level, tastes rich and dreamy, and is secretly… very doable in a regular, slightly chaotic home kitchen.

Most people think ganache cakes are complicated or require pastry-school confidence and a ruler. They don’t. This recipe walks you through the moist chocolate layers, the silky ganache, how to stack without stress, and how to fix the most common ganache panics before they spiral. You’ve got this.

Ingredients for chocolate ganache cake

Exact measurements will be in the recipe card on your site, but here are the key players (and why they matter) so you can shop smart.

For the cake:

• All-purpose flour: The structure. Nothing fancy needed.
• Unsweetened cocoa powder: This is where the deep chocolate flavor starts. Use a decent one—your cake will taste like it.
• Sugar: Sweetness and moisture.
• Baking powder + baking soda: Lift and tenderness.
• Salt: Not optional. It makes chocolate taste more like chocolate.
• Eggs (room temp): They mix in more smoothly. Cold eggs can make batter look a little curdled.
• Buttermilk (or substitute): Helps make the crumb soft and tender.
• Neutral oil: Keeps the cake moist even after a day in the fridge.
• Hot coffee or hot water: It “blooms” the cocoa so the chocolate flavor gets louder. Coffee won’t make it taste like a latte—promise.

For the ganache:

• Dark or semi-sweet chocolate (chopped or chips): Quality matters here because ganache is basically chocolate wearing a silk dress. For a helpful deep dive on chocolate and baking basics, King Arthur Baking is reliable.
• Heavy cream: The magic that turns melted chocolate into a luscious glaze/frosting.
• Butter (optional but lovely): Adds shine and a smoother mouthfeel.
• Pinch of salt or a splash of vanilla: Small thing, big difference.

Tools that make life easier: two 8-inch or 9-inch cake pans, parchment paper, mixing bowls, a whisk, and an offset spatula (or a butter knife you pretend is an offset spatula).

Ingredient Substitutions & Variations – chocolate ganache cake

This is a very flexible situation. Your kitchen, your rules.

Chocolate options (for ganache):

• Semi-sweet vs. dark: Semi-sweet gives a classic, crowd-pleasing sweetness. Dark makes it more intense and “grown-up.” Both work for this chocolate ganache cake.
• Milk chocolate: Totally doable, but the ganache will be softer and sweeter. You may want a little less cream.
• White chocolate ganache: A different vibe, but gorgeous. White chocolate is fussier (it can scorch), so use gentle heat and patience.

Dairy swaps:

• No buttermilk? Mix milk with a little lemon juice or vinegar and let it sit for 5 minutes.
• For a dairy-free ganache: Use full-fat coconut cream and dairy-free chocolate. It sets a bit softer but still tastes dreamy.
• For a dairy-free cake: Use plant milk soured with lemon + a neutral oil (and check your chocolate labels).

Cake variations:

• Box mix shortcut: If you’re short on time, use your favorite chocolate cake mix and still make the ganache from scratch. Nobody needs to know.
• Vanilla cake + chocolate topping: Make vanilla layers and pour the ganache over the top. It’s that classic birthday-sheet-cake energy, but fancier.

Flavor add-ins (pick one, don’t go wild):

• Espresso powder: Just a teaspoon in the batter makes the chocolate taste deeper.
• Orange zest: Bright and fancy.
• Peppermint extract: A tiny splash in the ganache for winter parties.
• A tablespoon of liqueur (like Baileys or Frangelico) in the ganache: Very “grown-up dessert table.”

How to Make chocolate ganache cake

Okay, here’s the thing about ganache: it’s not hard. It’s just particular about temperature. Once you respect that, it becomes the easiest “wow” factor in your dessert life.

1. Prep your pans and oven

Grease two round cake pans and line the bottoms with parchment. Preheat your oven.
Quick tip before we move on: parchment is the difference between “beautiful layers” and “I guess we’re doing a trifle now.”

2. Mix the dry ingredients

Whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt in a big bowl. No need to sift unless your cocoa is super clumpy.

3. Add the wet ingredients (then the hot coffee)

Add eggs, buttermilk, and oil. Mix until smooth.
Then slowly pour in hot coffee (or hot water) while whisking. The batter will be thin. That’s correct. Thin batter = moist cake. Trust me on this.

4. Bake

Divide batter evenly between pans and bake until a toothpick comes out with a few moist crumbs (not wet batter).
Let the cakes cool in the pans for about 10 minutes, then turn them out onto a rack to cool completely.

5. Make the ganache

Place chopped chocolate in a heatproof bowl. Heat heavy cream until it’s steaming and just barely simmering—no aggressive boiling.
Pour the hot cream over the chocolate. Don’t touch it for 2–3 minutes. Let it melt quietly like it’s in a spa.
Then whisk from the center outward until smooth and glossy. Add butter or vanilla if using.

For ganache ratios and why they work, Serious Eats has a great explanation.

6. Fill and stack

Once cakes are fully cool, level them if needed (or don’t—ganache covers a lot of sins).
Spread a thick layer of ganache between the layers. Add the top layer.

7. Ganache the outside

Let ganache cool to your preferred thickness:
– Pourable glaze: slightly warm, flows easily
– Spreadable frosting: cooled and thicker, like soft peanut butter

Spread over the top and sides. If you want drips, use slightly warmer ganache and nudge it to the edges.

8. Chill briefly to set

Pop the assembled cake in the fridge for 20–30 minutes so the ganache sets and slicing is cleaner.

Pro Tips & Common Mistakes – chocolate ganache cake

I’ve made this chocolate ganache cake enough times to have personally explored several unnecessary disasters. Learn from my chaotic energy.

– Don’t ganache a warm cake.
If the layers are even a little warm, the ganache will slide around like it’s trying to escape. Cool completely. Fully. No shortcuts.

– Thin batter isn’t a problem.
This cake batter is looser than you might expect. That’s what keeps the crumb moist and rich.

– Your ganache looks broken or grainy?
Usually the cream was too hot, or the chocolate overheated. Fix: add 1–2 teaspoons of warm cream and whisk gently. If it’s really stubborn, use an immersion blender to smooth it.

– Ganache too runny to frost?
Let it sit at room temp and thicken. If you’re impatient (me), stir every few minutes to speed it along.

– Ganache too thick?
Warm it in 5–10 second bursts in the microwave (stir well between bursts). Gentle is the whole theme here.

– Leveling is optional, not a moral test.
If your layers dome, you can trim them. Or you can stack them and use extra ganache to even things out. I support either lifestyle.

– Want clean slices?
Chill the cake, then slice with a warm knife (run it under hot water, wipe dry). It feels fancy and makes you look extremely competent.

Storage, Make-Ahead & Freezing – chocolate ganache cake

This chocolate ganache cake keeps really well, which is excellent news if you like “dessert now, dessert later” as a life philosophy.

• Room temperature: If your kitchen is cool, you can keep it covered for up to 1 day. The ganache may soften a bit.
• Fridge: Store covered for up to 5 days. The cake will be firmer when cold, so let slices sit out 20–30 minutes before serving for the best texture.
• Make-ahead: Bake the layers a day ahead, wrap well, and keep at room temp or refrigerated. Make ganache the day you assemble for the glossiest finish.
• Freezing: Wrap unfrosted layers tightly and freeze up to 2 months. Thaw overnight in the fridge, then assemble. You can freeze the finished cake, but the ganache can lose a little shine after thawing—still delicious, just less “mirror glaze” vibes.

Serving Suggestions – chocolate ganache cake

Now for the fun part—serving and pretending you’re not secretly proud of yourself.

• Classic: A big slice of cake with black coffee or strong tea. The bitterness balances the sweetness perfectly.
• Extra cozy: Serve slightly room temp with a glass of cold milk. Childhood magic, but with better chocolate.
• Fancy-but-easy: Add fresh raspberries or sliced strawberries on the plate. That tart bite makes the chocolate pop.
• Ice cream moment: Vanilla ice cream + a slice of cake is basically a standing ovation.
• Party trick: Sprinkle flaky salt on top of the ganache right before it sets. People will act like you have a cookbook deal.
