Ingredients for 2 kg chocolate cake
Twelve ingredients for a showstopping 2 kg chocolate cake that stays moist and rich.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Softened to room temperature |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred for smoothness |
| Dutch-Processed Cocoa Powder 🍫 | ¾ cup | High-quality for rich flavor |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Buttermilk 🥛 | 1 ½ cups | Room temperature for best results |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cacao minimum |
| Baking Soda 🧂 | 1 ½ tsp | Freshly measured |
| Salt 🧂 | 1 tsp | Fine sea salt preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Espresso Powder ☕ | 1 tbsp | Enhances chocolate depth |
| Vegetable Oil 🫒 | ½ cup | Lightens texture slightly |
| Instant Espresso Powder ☕ | 1 tbsp | Optional but recommended |
| Coffee Liqueur 🍸 | 2 tbsp | Kahlúa works perfectly |
The butter here is non-negotiable—use European-style if you can find it (like Plugrá or President), but any good unsalted will do. For the cocoa powder, Valrhona or Callebaut are the gold standard, but Hershey's Special Dark works in a pinch. The buttermilk needs to be at room temperature—cold buttermilk creates dense cakes. I always grab extra cocoa powder since it's the secret to that deep, velvety flavor. The dark chocolate chips should be at least 70% cacao—Ghirardelli or Lindt Excellence are my go-tos, but any quality brand works. Pro tip: Toast the cocoa powder in a dry pan for 30 seconds to deepen the flavor (trust me on this).
No buttermilk? Mix 1.5 tbsp lemon juice or vinegar with 1.5 cups milk and let sit for 5 minutes. Running low on coffee liqueur? Double the espresso powder—it's the same flavor profile without the alcohol. Swap dark chocolate chips for chopped chocolate bars if you prefer, but keep the 70% cacao minimum. The vanilla extract should be pure—Madagascar Bourbon has the best balance of sweetness and depth. For a lighter texture, use half butter, half oil instead of all butter. And if you're worried about dry crumbs, add 1 tbsp sour cream to the batter for extra moisture.
This batter keeps in the fridge for 3 days covered tightly, but bake it fresh for best results. The cake reheats beautifully—just wrap a slice in foil and microwave for 20 seconds. For make-ahead prep, bake the cake, cool completely, then wrap tightly in plastic wrap and store at room temperature for up to 5 days. Freeze uncut cakes for up to 3 months by wrapping tightly in plastic and foil. When ready to serve, bring to room temperature for those perfect slices. The flavor actually improves after a day or two, so plan ahead for gatherings—your guests will thank you.

Step-by-step instructions for a 2 kg chocolate cake
Here's how to create a rich, moist chocolate cake that stays tender for days—no dry crumbs in sight.
Cream Butter, Sugar, and Espresso Powder Together
In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. The mixture should nearly double in volume and become pale, with ribbons forming when the paddle is lifted. This step incorporates air, which creates that signature tender crumb.
Next, add the 1 tbsp espresso powder and 1 tbsp instant espresso powder (if using). Mix on low speed for 30 seconds to evenly distribute. The espresso enhances the chocolate flavor without adding bitterness. Here's the thing—don't rush this step. Under-creaming leads to dense, cakey results instead of that melt-in-your-mouth texture we're after.
Incorporate Wet Ingredients and Coffee Liqueur
Add the 1.5 cups buttermilk and 2 tbsp coffee liqueur to the butter-sugar mixture. Mix on low speed for 1 minute until just combined. The buttermilk adds moisture and a subtle tang that balances the richness of the chocolate, while the coffee liqueur deepens the flavor profile. I like to use a spatula to scrape down the sides of the bowl at this point to ensure everything is fully incorporated.
In a separate bowl, whisk together the 0.75 cup Dutch-processed cocoa powder, 2.5 cups all-purpose flour, 1.5 tsp baking soda, and 1 tsp salt. Sift the dry ingredients directly into the wet mixture to prevent lumps. With the mixer on low speed, combine everything until just mixed—you should still see some flour streaks. Overmixing develops gluten, which can make the cake tough. Stop mixing as soon as the dry ingredients disappear.
Fold in Chocolate Chips and Vanilla
Remove the bowl from the mixer and gently fold in the 1.5 cups dark chocolate chips using a silicone spatula. You want to distribute them evenly throughout the batter without breaking them up too much—this ensures pockets of gooey chocolate in every bite. Add the 2 tsp vanilla extract and the 0.5 cup vegetable oil, then fold these in as well. The oil helps create a tender crumb and prevents the cake from drying out.
Here's where it gets fun—give the batter one final stir by hand to ensure the chocolate chips are evenly distributed. The batter will be thick but not stiff. If it seems too thick, you can add 1-2 tablespoons of buttermilk to loosen it slightly. This is your last chance to adjust the consistency before baking.
Divide and Bake in Two Pans
Preheat your oven to 350°F and grease two 9-inch round cake pans with nonstick spray or softened butter. Line the bottoms with parchment paper circles for easy removal. Divide the batter evenly between the two pans, smoothing the tops with a spatula. Tap each pan gently on the counter a few times to release any air bubbles—this ensures even rising and a smooth top.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. The edges should be set, and the tops should spring back when gently pressed. I know it seems counterintuitive, but don't overbake—this cake relies on moisture, and the resting time will help it set properly. Rotate the pans halfway through baking for even heat distribution.
Cool and Assemble for Maximum Moisture
Once baked, remove the cakes from the oven and let them cool in their pans for 10 minutes. Then, transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and allows the cakes to set properly. While they cool, prepare your favorite frosting or glaze—this cake is versatile and pairs well with chocolate ganache, cream cheese frosting, or even a simple dusting of cocoa powder.
To assemble, place one cake layer on a serving plate and spread your chosen frosting evenly. Top with the second cake layer, pressing gently to create a smooth surface. For extra moisture, you can also brush the layers with a simple syrup made by heating ½ cup water and ½ cup sugar until dissolved, then cooling. This step ensures your cake stays moist for days, even at room temperature. Serve slices immediately or store covered at room temperature for up to 3 days.
Pro Tips For Making 2 Kg Chocolate Cake
- MELT BUTTER SLOWLY: If you’re dumping cold butter straight into the sugar and mixing, you’re fighting the recipe. Warm the butter to room temp first—just until it softens like a stick of clay, not liquid. This ensures even creaming with the sugar, which prevents a grainy texture later. (Yes, even if you’re impatient like me, don’t skip this.)
- SIFT THE COCOA: Dutch-processed cocoa powder clumps like a grumpy old cat if you don’t handle it right. Sift it with the flour before adding to the batter—this breaks up any lumps and guarantees a silky-smooth finish. I learned this the hard way after biting into a cake with texture like sandpaper.
- DON’T OVERMIX THE BATTER: Once you fold in the buttermilk, stop mixing the second everything comes together. Overworking the batter introduces air bubbles that’ll make your cake dense and tough. Give it two gentle stirs—just enough to combine, nothing more. Your future self will thank you for not turning this into a bread loaf.
- USE A TOOTHPICK TEST: The cake’s done when the center springs back when you press it—but don’t rely on time alone. Insert a toothpick 2 cm into the middle; if it comes out with moist crumbs (not wet batter), pull it out. Leave it in 5 more minutes if it’s still sticky. (This isn’t the prettiest method, but it’s the tastiest.)
Wine and beer pairings for this dish
Red Wine Pairings
For this rich, dense chocolate cake, reach for a bold red wine with enough tannins to stand up to the deep cocoa flavors. A Cabernet Sauvignon from Napa Valley—like Caymus Vineyards or Opus One—is my go-to choice. The dark fruit notes and firm tannins complement the chocolate's intensity while the wine's acidity cuts through the richness. Serve it slightly chilled (55-60°F) to enhance its freshness against the cake's warmth. 🍷
Port Wine Glaze
Instead of wine, consider a port wine glaze—simmer ½ cup ruby port with 1 cup powdered sugar and 2 tbsp heavy cream until thickened. Drizzle this over the cake before serving for a luxurious finish. The port's caramel and berry notes mirror the cake's chocolate depth while adding a sophisticated touch. I love using Graham's Six Grapes for its balanced sweetness and fruitiness.
Champagne or Sparkling Wine
For a lighter contrast, pair your cake with dry Champagne or a crisp Prosecco. The effervescence cleanses your palate between bites, letting the chocolate's richness shine. Opt for a Brut Champagne like Veuve Clicquot or an Italian Prosecco DOCG such as La Marca. Serve well-chilled (45-50°F) to maintain its lively bubbles and bright acidity. ✨
Coffee-Infused Liqueur
Since the cake already has coffee liqueur, enhance the pairing by serving a smooth coffee liqueur like Kahlúa or Tia Maria on the side. The coffee notes harmonize with the cake's espresso powder, creating a cohesive flavor experience. Serve it neat or over ice for a dessert-friendly cocktail. For a non-alcoholic option, try cold brew coffee with a splash of cream—it mirrors the cake's depth without the alcohol.
Dark Chocolate Beer
For beer lovers, a dark ale or stout with chocolatey undertones is perfect. Try Guinness or Deschutes The Abyss—both have roasted malt flavors that echo the cake's cocoa. The beer's bitterness balances the sweetness, creating a satisfying contrast. Serve the beer slightly chilled (40-45°F) to preserve its creamy texture and deep flavors. 🍺

Frequently asked questions
Can I make this 2 kg cake in a single pan instead of two?
Not recommended for this recipe. A single 9-inch pan would be too shallow for the batter volume, causing uneven baking and potential overflow. The cake's density relies on proper layering, which requires the two 9-inch pans. If you must use one pan, consider a deep 10-inch springform pan and reduce baking time by 5-7 minutes—but expect less even texture.
Why does this cake need espresso powder when it already has coffee liqueur?
The espresso powder enhances the chocolate flavor without adding moisture (like the liqueur does). The powder intensifies the cocoa's depth while the liqueur adds richness and a subtle caramel note. Together, they create that professional bakery taste. Think of it like a flavor bridge—one layer for dry intensity, one for liquid depth.
How do I prevent cracks on the top of my chocolate cake?
Cracks usually form from rapid cooling or overmixing. To avoid them:
- Let the cake cool in the pan for 10 minutes before transferring,
- Don't open the oven door too early, and
- Avoid overmixing the batter—stop as soon as dry ingredients disappear. For extra insurance, brush the warm cake tops with simple syrup immediately after baking.
Can I substitute buttermilk with regular milk?
Not directly—regular milk won't provide the same acidity and moisture. For a quick substitute, mix 1.5 tbsp lemon juice or white vinegar with 1.5 cups milk and let sit for 5 minutes until slightly curdled. This mimics buttermilk's tangy properties. The acidity helps activate the baking soda for proper rise and tenderness.
How long can I keep the baked cake before frosting?
Wrap the cooled cake layers tightly in plastic wrap and store at room temperature for up to 3 days before frosting. The cake actually improves in flavor as it sits! For longer storage, freeze the unfrosted layers for up to 3 months. Thaw overnight in the fridge before assembling—this prevents condensation that can make the cake soggy.
