Ingredients for 10 round chocolate cake
Twelve essential ingredients for a restaurant-quality 10-inch chocolate cake with velvety ganache drizzle.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | High-quality Dutch-processed |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smoothness |
| Light Brown Sugar 🍚 | ½ cup | Packed for moisture |
| Buttermilk 🥛 | 1 cup | Room temperature for best results |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for creaming |
| Baking Powder 🍞 | 2 tsp | Double-acting preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon |
| Dark Chocolate Chips 🍫 | 1 cup | 70% cocoa, chopped |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Cold for ganache |
| Semi-Sweet Chocolate Bars 🍫 | 8 oz | High-quality, chopped |
| Powdered Sugar 🍚 | 1 cup | For dusting |
The cocoa powder and chocolate are non-negotiable for that deep, rich flavor. Valrhona or Guittard are my go-tos for cocoa powder—Dutch-processed ensures smoothness without bitterness. For chocolate, Ghirardelli or Lindt bars melt flawlessly. The buttermilk adds moisture without overpowering the chocolate, so don't substitute with regular milk. The butter should be cold when creaming to create air pockets for that tender crumb. European-style butter like Plugrá has higher fat content, perfect for this recipe. Measure your flour by weight if possible—280 grams ensures consistency, as volume can vary with sifting.
No buttermilk? Mix 1 cup milk + 1 tbsp vinegar, let sit 5 minutes. Substitute the brown sugar with additional granulated sugar if needed, but the moisture difference matters. For the ganache, heavy cream must be cold—room temperature cream won't thicken properly. The chocolate bars should be 70% cocoa or higher for that professional bitterness. If you can't find semi-sweet bars, use dark chocolate chips (60-70%) plus extra cocoa powder to balance. The powdered sugar is purely decorative, but it adds that bakery-finish touch—sift it through a fine strainer for a flawless dusting.
Store the cake layers wrapped in plastic at room temperature for up to 3 days—the flavor actually improves as it sits. The ganache keeps well in the fridge for 5 days, but bring it to room temperature before drizzling to maintain its velvety consistency. For longer storage, freeze the cake layers separately for up to 3 months. The ganache can be reheated gently in the microwave—15-second bursts until smooth. To serve, let the cake sit at room temperature for 30 minutes before slicing for clean cuts. The ganache will set slightly as it cools, but reheating restores its glossy finish.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when my mixer’s on the fritz—just whisk the dry ingredients (flour, cocoa, sugars) in one bowl, then fold in the buttermilk. The secret’s in creaming the sugars first, even by hand, for that tender crumb without a single elbow grease complaint.
- Rich Without Overpowering: That combo of granulated and light brown sugar? It’s the magic. The brown sugar adds a subtle caramel depth while the cocoa stays true to its chocolatey roots—no artificial aftertaste here. Honestly, it’s the kind of cake where every bite feels like a hug.
- Party in a Box: Ten rounds mean you can slice it for a crowd or save half for later—no sad single-serving waste. I’ve used it for birthday desserts, potlucks, and even as a dramatic centerpiece for my book club’s meetings. (Yes, even when no one’s expecting cake.)
- Budget-Friendly Luxury: Flour, cocoa, sugar, buttermilk—these are pantry staples that won’t break the bank. I’ve made this cake for under $10 total, and it still tastes like you spent an hour decorating it. Leftovers? They disappear faster than my willpower on a Sunday afternoon.
Step-by-step instructions for 10-Inch round chocolate cake
Here's the method for achieving a perfectly moist crumb with a rich chocolate flavor.
Prepare the Cake Batter
Preheat your oven to 350°F and grease a 10-inch round cake pan, then line the bottom with parchment paper. In a medium bowl, whisk together the 2.5 cups all-purpose flour, 0.75 cup unsweetened cocoa powder, 2 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients directly into the bowl to ensure an even distribution and eliminate lumps.
In a separate large bowl, cream together the 1 cup unsalted butter and both sugars—2 cups granulated sugar and 0.5 cup light brown sugar3-4 minutes. This step incorporates air, which helps create a tender crumb. Scrape down the sides of the bowl with a spatula to ensure even mixing.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 2 tsp vanilla extract and the 1 cup buttermilk until the mixture is smooth. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Avoid overmixing, as this can lead to a dense cake. Fold in the 1 cup dark chocolate chips by hand using a silicone spatula.
Bake the Cake to Perfection
Pour the batter into the prepared cake pan and smooth the top with a spatula. Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean. The cake should spring back slightly when gently pressed in the center, indicating it’s fully baked.
I always check for doneness at 30 minutes—if the top appears set but the toothpick test isn’t clean, cover the cake loosely with foil and continue baking for another 5-10 minutes. Overbaking can dry out the cake, so keep a close eye on it during the last few minutes.
Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes. This brief cooling period helps the cake set slightly before transferring it to a wire rack to cool completely. Avoid cooling the cake directly on the rack while it’s hot, as this can cause the bottom to become too dry.
Prepare the Chocolate Ganache
While the cake cools, prepare the ganache by chopping the 8 oz semi-sweet chocolate bars into small pieces. Place the chopped chocolate in a heatproof bowl set over a saucepan of simmering water, ensuring the bottom of the bowl doesn’t touch the water. Stir in the 1.5 cups heavy whipping cream and let the mixture sit for 2-3 minutes, or until the chocolate is fully melted and the ganache is smooth.
Remove the bowl from the heat and let the ganache cool slightly, stirring occasionally, until it reaches a thick but pourable consistency. This should take about 5-10 minutes. The ganache is ready when it coats the back of a spoon but still flows easily. If it thickens too much, gently reheat it over low heat and stir until smooth again.
Assemble and Drizzle the Cake
Once the cake is completely cool, place it on a serving plate. Pour the cooled ganache over the top of the cake, allowing it to drip down the sides naturally. Use a spatula to spread any excess ganache evenly over the surface, ensuring full coverage. Let the ganache set for 15-20 minutes at room temperature.
While the ganache sets, sift the 1 cup powdered sugar over a fine-mesh sieve to remove any lumps. Once the ganache has set slightly, dust the top of the cake with the powdered sugar for a beautiful finishing touch. Serve the cake immediately to enjoy the perfect balance of moist crumb and rich, velvety ganache.
Pro Tips For Making 10 Round Chocolate Cake
- Sift the Cocoa: Mixing cocoa powder directly into dry ingredients creates clumps that ruin texture. Sift it first with the flour—yes, even if it looks powdery—then whisk the dry mix until smooth. I learned this the hard way when my first batch had gritty pockets.
- Weigh the Buttermilk: Buttermilk varies in thickness, and measuring by volume leads to dry or gummy cake. Use a kitchen scale for 240g (1 cup + 2 tbsp) to guarantee consistency. I was skeptical until I tried it—now I never go back.
- Check Doneness Early: This cake sets fast, and overbaking turns it dense. Insert a toothpick at 25–30 minutes—it should have moist crumbs, not wet batter. If unsure, pull it at 28 minutes; residual heat finishes the job.
- Swap Brown Sugar for White: Light brown sugar adds moisture, but if you’re short on time, use white sugar plus 1 extra tbsp molasses (or ½ tsp vanilla extract). The cake won’t be identical, but it’ll still be rich and fudgy—just less caramelized. (Your future self will thank you.)
Perfect pairings for this 10 round chocolate cake
Fruit Toppings
Fresh berries like raspberries or blackberries add a vibrant contrast to the rich chocolate. I like to arrange them in a circular pattern on top of the ganache drizzle for a visually stunning presentation. For extra flair, drizzle raspberry jam (about 2 tbsp) in zigzag patterns before adding the berries. 🍓
Creamy Pairings
Whipped cream is a classic choice—pipe it around the edges of the cake or dollop it on top for a light, airy contrast. For a more decadent touch, add ½ cup mascarpone cheese mixed with 1 tbsp powdered sugar and 1 tsp vanilla extract. Spread this mixture over the ganache before dusting with powdered sugar for a luxurious finish.
Coffee Infusion
If you love coffee, try adding a 1 tsp instant espresso powder to the cake batter for a subtle depth of flavor. For the ganache, stir in 1 tbsp coffee liqueur (like Kahlúa) while it’s warm for a boozy twist. Serve with a shot of espresso on the side for an adult dessert experience. ☕
Nutty Crunch
Toasted pecans or hazelnuts add texture and balance the richness. Pulse ½ cup pecans in a food processor until finely chopped, then sprinkle over the ganache before it sets. For a more intense flavor, toast the nuts in a dry skillet over medium heat for 3-4 minutes until golden and fragrant.
Boozy Enhancements
Add 2 tbsp dark rum or 1 oz orange liqueur to the ganache while it’s warm for a sophisticated flavor. For a citrusy note, zest 1 orange and fold it into the batter. The bright acidity cuts through the chocolate’s richness beautifully. 🍊
Spiced Accents
Warm spices like cinnamon or cardamom elevate the chocolate’s depth. Sprinkle ½ tsp ground cinnamon over the ganache while it’s still wet, or infuse the ganache with ¼ tsp cardamom pods while simmering. The aromatic notes add complexity to every bite.

Frequently asked questions
Can I bake this in a different-sized pan?
Yes, but adjust the baking time. For a 9-inch pan, bake 25-30 minutes—the cake will be thicker and may need 5 extra minutes. For a 12-inch pan, reduce oven temp to 325°F and bake 40-45 minutes. Always check with a toothpick at the lower end of the time range to avoid overbaking.
Why does my chocolate cake turn out dry?
Overbaking is the #1 cause—check the cake at 30 minutes and remove when a toothpick comes out with moist crumbs, not clean. Another culprit is using too much flour (weigh it for accuracy) or old baking powder. For extra moisture, brush warm layers with simple syrup (½ cup sugar + ¼ cup water) before filling.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus ½ tsp xanthan gum. Use 1 cup buttermilk substitute (almond milk + vinegar) and reduce baking powder to 1.5 tsp. Bake in a 325°F oven for 45-50 minutes—gluten-free cakes need lower heat and longer time to set properly.
Can I make the ganache ahead of time?
Prepare the ganache up to 3 days ahead and store it in an airtight container at room temperature. Reheat gently in 15-second microwave bursts until smooth and pourable. For longer storage (1 month), refrigerate and reheat over a double boiler. The texture will be perfect when it coats the back of a spoon but still drizzles easily.
What's the best way to store leftovers?
Wrap individual slices tightly in plastic wrap and store at room temperature for 2 days. For longer storage, freeze slices between parchment paper for up to 1 month. Thaw at room temperature for 1 hour—microwaving can make the ganache too runny. The cake actually tastes better the next day as flavors meld!
