Ingredients You’ll Need
It’s amazing how a handful of humble pantry staples, when combined in the right way, transform into something truly luxurious. Each ingredient in this Decadent Chocolate Cake with Ganache Glaze plays a star role: the cocoa brings depth, the eggs add richness, and the ganache delivers that irresistible shine. Here’s what you’ll need for chocolate perfection:
- All-purpose flour: The foundation for a soft, even crumb—measure carefully for the perfect texture.
- Unsweetened cocoa powder: Choose a high-quality cocoa for a deep, complex chocolate flavor.
- Granulated sugar: Sweetens the cake and also helps keep it tender and moist.
- Baking powder and baking soda: This duo gives the cake its beautiful rise and lightness.
- Salt: Just enough to boost the chocolatey goodness and keep everything balanced.
- Large eggs (room temperature): They add structure, richness, and help bind everything together.
- Whole milk: Makes the crumb extra moist and gives a subtle creaminess to each bite.
- Vegetable oil: Oil ensures the cake stays tender, even after a day or two—no dry cake here!
- Vanilla extract: A splash of vanilla rounds out and enhances the chocolate flavor.
- Boiling water or hot coffee: Pour this in last—the warmth opens up the cocoa and makes the cake ultra-moist (coffee deepens the chocolate flavor, water keeps things classic).
- Semi-sweet chocolate, finely chopped: For the ganache, use a good semi-sweet chocolate, which melts smoothly and gives that luscious glaze.
- Heavy cream: This creates the velvety texture in the ganache that everyone loves.
- Unsalted butter (optional): Stir a bit into the ganache for extra shine and richness—it’s optional, but absolutely worth it!
- Chocolate curls or shavings: For that show-stopping finish on top and around the base.
How to Make Decadent Chocolate Cake with Ganache Glaze
Step 1: Prep Your Pans and Oven
Begin by preheating your oven to 350°F (175°C). Generously grease two 8-inch round cake pans, then line the bottoms with parchment paper for effortless removal. This little step means your cakes won’t stick or tear—just pop out beautifully every time.
Step 2: Sift and Mix the Dry Ingredients
In a large mixing bowl, sift together the flour, cocoa powder, granulated sugar, baking powder, baking soda, and salt. Sifting really is worth the extra minute—it prevents any lumps and ensures that every bite of your Decadent Chocolate Cake with Ganache Glaze is uniformly soft and chocolaty throughout.
Step 3: Add the Wet Ingredients
Crack in your eggs, pour in the milk, vegetable oil, and add vanilla extract right into the dry mix. Get out your electric mixer and blend everything on medium speed for about two minutes. You’ll notice the batter is already looking silky and deeply chocolatey—resist the urge to taste-test just yet!
Step 4: Stir in Boiling Water (or Coffee)
Now comes the magic: stir in one cup of boiling water or, for extra depth, hot coffee. The batter will look very thin compared to other cakes, but that’s the secret behind its melt-in-your-mouth texture. Don’t worry—this runnier batter bakes up into the moistest cake layers you’ve ever tasted.
Step 5: Bake the Cakes
Divide the batter evenly between your prepared pans. Pop them into the oven and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool in their pans for 10 minutes, then gently turn them onto wire racks to finish cooling completely. This cooling step is key—your ganache glaze will go on perfectly smooth when the cakes are at room temperature.
Step 6: Make the Ganache Glaze
While the cakes are cooling, it’s ganache time! Heat the heavy cream in a saucepan over medium heat until just steaming (don’t let it boil). Pour the hot cream over your finely chopped semi-sweet chocolate and let it sit for 3 minutes—then stir, stir, stir until silky and smooth. For that pro-level shine, swirl in a little butter at the end, if you like. Set aside and let the ganache thicken until it’s pourable but not runny.
Step 7: Assemble and Glaze
Set one cake layer on a serving plate. If you want extra decadence, spread a thin layer of ganache right on top before gently placing the second cake layer. Now for the fun part: pour the glossy ganache over the top, letting it cascade down the sides in beautiful drips. Decorate with chocolate curls or shavings around the edges for a bakery-worthy finish.
Step 8: Chill and Slice
For the cleanest slices and prettiest glaze, pop the finished cake in the fridge for 30 minutes to set. Once it’s ready, slice generously and serve. Each forkful is guaranteed to bring smiles!
How to Serve Decadent Chocolate Cake with Ganache Glaze

Garnishes
This cake absolutely loves a little extra flair! Pile on a tumble of chocolate curls, scatter shimmering chocolate shavings, or even add a dusting of cocoa powder on top. If you’re feeling playful, a handful of fresh berries or a sprinkle of edible gold leaf can add that touch of celebration. The glossy ganache glaze is so inviting, anything you add will look like it came out of a pastry shop window.
Side Dishes
Pair your Decadent Chocolate Cake with Ganache Glaze with a scoop of vanilla bean ice cream to complement its richness, or a swirl of softly whipped cream. For a touch of tartness, fresh raspberries or sliced strawberries keep the chocolate from feeling too heavy and add a lovely burst of color to your dessert plate.
Creative Ways to Present
For birthdays or special occasions, try serving as individual mini cakes—cut out rounds with a cookie cutter and glaze just like the big version. Or, layer thin slices with whipped cream and berries in clear glasses for stunning chocolate parfaits. The dramatic chocolate drips make this cake the star on any dessert table, so don’t be afraid to decorate it simply and let it shine!
Make Ahead and Storage
Storing Leftovers
Leftover Decadent Chocolate Cake with Ganache Glaze is a gift that just keeps giving! Store slices in an airtight container at room temperature for up to 2 days, or extend their life in the fridge for up to 5 days. If chilling, let the cake sit out for about 30 minutes before serving so the ganache softens luxuriously.
Freezing
This cake freezes beautifully, with or without the ganache glaze. Wrap individual slices tightly in plastic wrap and then foil, or freeze the whole cake (double-wrapped) for up to 2 months. Thaw overnight in the fridge for best results, and your cake will taste just as vibrant and moist as the day you baked it.
Reheating
If you like your cake just slightly warm, pop a refrigerated slice in the microwave for about 10 seconds. Be careful not to overheat, or the ganache may melt completely. The hint of warmth makes the chocolate flavors bloom and the ganache irresistibly creamy.
FAQs
Can I make Decadent Chocolate Cake with Ganache Glaze ahead of time?
Absolutely! You can bake the cake layers a day or two in advance—just wrap them tightly and store at room temperature. The ganache glaze can also be made ahead and gently rewarmed to pouring consistency when you’re ready to assemble.
What if I don’t have coffee for the batter?
No worries! Boiling water works perfectly in this recipe, giving you the moist texture you want. Coffee simply deepens the chocolate notes, so use whichever you prefer or have on hand.
Can I make this recipe gluten free?
Yes! Substitute your favorite 1:1 gluten-free all-purpose flour blend to make this decadent treat accessible to all. Just double-check the baking powder and other ingredients to ensure they’re certified gluten-free.
Do I need to use butter in the ganache?
No, butter is optional. It adds extra sheen and a hint of richness, but the ganache will still be smooth and delicious without it. If you want the glaze super glossy, go ahead and add it!
What’s the secret to perfectly smooth ganache?
Finely chop your chocolate and make sure the cream is heated until just steaming, not boiling. Allow the hot cream to sit on the chocolate for several minutes before stirring—patience gives you a silky, lump-free ganache every time.
