Ingredients for 10 round chocolate cake
Precision ingredients for restaurant-quality 10-round chocolate cake in one pan—rich layers and stable buttercream.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 5 cups | Sifted for even texture |
| Unsalted Butter 🧈 | 2 ½ cups | Room temperature, European-style preferred |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred for smoother batter |
| Cocoa Powder 🍫 | 1 cup | Dutch-processed for richer flavor |
| Large Eggs 🥚 | 6 whole | Room temperature, separated |
| Baking Powder 🧂 | 1 ½ tsp | Freshly measured |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon |
| Whole Milk 🥛 | 1 ½ cups | Room temperature |
| White Chocolate Chips 🍫 | 1 ½ cups | High-quality, 15% cocoa |
| Powdered Sugar 🍚 | 4 cups | For buttercream, sifted |
| Heavy Whipping Cream 🥛 | 2 cups | Cold, full-fat preferred |
| Cocoa Powder 🍫 | ¼ cup | For buttercream enrichment |
| Almond Extract 🌿 | ½ tsp | Optional, for depth |
The cocoa powder is non-negotiable here. Dutch-processed creates a smoother, richer flavor that pairs perfectly with the white chocolate chips. Valrhona or Guittard are my go-tos, but any high-quality brand works. The butter should be European-style—Plugrá or Miyoko’s melt beautifully for that tender crumb. Room temperature is critical: press a cold butter pat into a warm bowl for 10 minutes if needed. For the white chocolate chips, Ghirardelli or Lindt Excellence melt smoothly without graininess. Buy in bulk if you’re making this often—it keeps for 6-12 months in a cool, dark place.
No Dutch-processed cocoa? Natural cocoa with an extra 0.25 cup sugar works, but the flavor profile shifts slightly. European butter unavailable? Land O’Lakes or Kerrygold are solid substitutes, but expect a slightly denser texture. Room temperature eggs are essential—microwave 30 seconds in shell if they’re straight from the fridge. The buttercream requires cold cream for stability. Chill the bowl and beaters for 10 minutes beforehand. For a nutty depth, swap the almond extract for 1 tsp espresso powder. The powdered sugar must be sifted—Domino or C&H brands work best for smooth frosting.
Store the cake layers in an airtight container between parchment-lined rounds for up to 3 days at room temperature. The buttercream can be made 1 day ahead—just re-whip before use. For longer storage, freeze the fully assembled cake (without frosting) for 3 months30-second bursts in the microwave to prevent burning. Always use a kitchen scale for precise measurements—1 cup flour varies by brand. Preheat your oven to 350°F and let it stabilize for 15 minutes before baking.
Why You’ll Love This Recipe
- Here’s what sold me: the balance of sugar and cocoa powder keeps the flavor deep but never overpowering. That first bite? It’s like a hug for your taste buds—smooth, slightly sweet, with just enough chocolate to make you reach for another slice.
- I’ll be real: this cake stays moist for days, which means I can bake one batch and enjoy it for breakfast, dessert, or even a mid-afternoon pick-me-up. The butter and eggs keep it rich but not greasy, so it’s actually a smart way to stretch your grocery budget.
Step-by-step instructions for layered fudgy chocolate cake
Master this one-pan technique for a decadent, moist chocolate cake with perfect layers.
👨🍳 Step 1: Prepare the Cake Batter
Preheat your oven to 350°F and grease a 10-inch round cake pan thoroughly with butter, then dust with flour. In a stand mixer fitted with the paddle attachment, cream together the 2.5 cups unsalted butter and 2.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. This step is crucial—you’re incorporating air that will create that tender crumb.
Add the 6 whole large eggs one at a time, mixing well after each addition. Then whisk in the 2 tsp vanilla extract and 1.5 cups whole milk until smooth. In a separate bowl, sift together the 5 cups all-purpose flour, 1 cup cocoa powder, 1.5 tsp baking powder, and 1 tsp salt. Gradually add the dry ingredients to the wet mixture on low speed until just combined—don’t overmix or your cake will be dense.
🍳 Step 2: Create the Chocolate Chip Layers
Fold in the 1.5 cups white chocolate chips using a spatula, making sure they’re evenly distributed throughout the batter. Pour half of the batter into your prepared cake pan and spread it evenly. Sprinkle half of the remaining white chocolate chips over the first layer, then add the remaining batter and spread it evenly over the chips. Top with the remaining chocolate chips.
Here’s the secret: don’t overfill the pan. The batter should come about ¾ of the way up the sides—this allows for proper rising without overflowing. Tap the pan gently on the counter twice to eliminate any air bubbles that might have formed during pouring.
🔥 Step 3: Bake to Perfect Doneness
Bake for 45-50 minutes until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter. The cake should spring back slightly when pressed gently in the center. I know it seems like a long time, but patience here ensures that fudgy texture we’re after—underbaking leaves it too dense, overbaking makes it dry.
Let the cake cool in the pan for 15 minutes before transferring it to a wire rack to cool completely. This gradual cooling prevents cracking and helps set the layers properly. The cooling process also allows the flavors to meld, giving you that rich chocolate depth throughout each slice.
🥘 Step 4: Prepare the Chocolate Buttercream
While the cake cools, prepare the buttercream by beating the 2 cups heavy whipping cream until soft peaks form. In a separate bowl, beat the 2.5 cups unsalted butter until smooth, then gradually add the 4 cups powdered sugar, 0.25 cup cocoa powder, and 0.5 tsp almond extract while mixing on medium speed. Once combined, add the whipped cream and beat until light and fluffy.
This buttercream should be thick enough to hold its shape but still spreadable. If it’s too thick, add 1-2 tablespoons milk at a time until you reach the perfect consistency. The almond extract adds subtle depth, but don’t worry if you skip it—it’s optional but recommended for that extra layer of flavor.
🍽️ Step 5: Assemble and Decorate
Once the cake is completely cool, use a serrated knife to level the top if needed. Spread half of the buttercream evenly over the cake, then add the second layer if you’ve chosen to bake two separate cakes (though this one-pan method creates one thick layer). Top with the remaining buttercream and spread it to the edges, creating a smooth finish.
For decoration, pipe swirls of buttercream along the edges or dust with additional cocoa powder for a simple, elegant finish. The contrast between the rich chocolate cake and velvety buttercream creates that perfect balance of textures we love in chocolate desserts. Serve at room temperature for the best experience—this cake keeps well for up to 3 days covered at room temperature.
Pro Tips For Making 10 Round Chocolate Cake
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot cocoa powder makes lumps that never fully dissolve. Instead, melt the butter first, then whisk it into the cocoa and sugar before adding flour. The batter will be smoother, and your cake won’t end up with gritty pockets.
- Sift That Cocoa: Cocoa powder is sneaky—it clumps like a stubborn guest at a party. Sift it with the flour twice (yes, even if it looks fine). This keeps your cake light instead of dense, and trust me, you’ll notice the difference in every bite.
- Room-Temp Eggs Matter: Cold eggs? They’ll curdle your batter faster than a bad joke at a family gathering. Let them sit out for 30 minutes before cracking—just enough time to make sure they’re warm to the touch. Your cake will bake evenly, no surprises.
- Grease Pans Like a Pro: Butter the pans, then dust with flour—but tap out the excess so it’s not a floury mess. For extra insurance, sprinkle a little cocoa powder in the pans before adding the batter. This keeps your cake from sticking, no matter how much you love it.
Pro cooking tips for perfect results
Pan Prep Secrets
Grease your 10-inch round cake pan with ½ cup melted butter and let it cool slightly before dusting with 2 tablespoons flour. The key is to use a pastry brush for even distribution—don’t skip this step!
I also recommend lining the bottom with parchment paper to prevent sticking, especially if you’re baking in a dark-colored pan that can bake unevenly. 🧼
Batter Layering
Pour half the batter into the pan, then sprinkle ½ cup white chocolate chips evenly across the surface. Add the remaining batter and top with another ½ cup chips. Use a small offset spatula to smooth the top—this creates clean layers.
Pro tip: Gently tap the pan on the counter twice after adding the second layer to pop any air bubbles that form during pouring.
Baking Time Hacks
Your oven might run hot or cold, so adjust baking time accordingly. I test doneness at 40 minutes—if the toothpick comes out clean, it’s done. If not, bake for 5 more minutes.
The cake should pull away slightly from the pan edges and have a springy texture when pressed gently. For extra insurance, use an oven thermometer to confirm your oven’s actual temperature—many run 25°F hotter than set. 🌡️
Cooling Like a Pro
Let the cake cool in the pan for exactly 15 minutes before transferring to a wire rack. This gradual cooling prevents cracks and helps the layers set properly. I like to run a thin knife around the edges of the pan to loosen the cake before removing it.
Never cool the cake completely in the pan—this causes moisture to get trapped and makes the cake gummy.
Buttercream Stability
Chill your mixing bowl and beaters in the freezer for 10 minutes before whipping the cream. This ensures your buttercream reaches proper stiffness. For extra stability, add 1 tablespoon cornstarch to the powdered sugar mixture.
The secret to smooth buttercream is patience—whip the cream to stiff peaks before combining with the butter mixture. If your frosting is too soft, pop it in the fridge for 15 minutes to firm up before decorating.
Decorating Tricks
Use a bench scraper to create clean edges when spreading buttercream. For swirls, pipe buttercream onto the cake in 1-inch sections, then drag a toothpick through the center to create elegant patterns. Dust with cocoa powder using a fine-mesh sieve for a professional finish.
I like to add a pinch of espresso powder** to the cocoa for deeper flavor—just mix it directly into the powder before dusting. ✨

Frequently asked questions
Can I make this cake in a different pan size?
Yes, but adjust baking times carefully. For a 9-inch pan, bake 35-40 minutes—the batter will rise higher. For a 12-inch pan, reduce baking time to 30-35 minutes and spread batter thinner. Always use an oven thermometer and check doneness with a toothpick at 25°F below the recommended time. The key is to avoid overbaking, which dries out the texture.
Why does my cake crack on top?
Cracking usually happens from uneven cooling or overmixing. Let the cake cool in the pan for exactly 15 minutes before removing, and avoid opening the oven door during baking. For extra insurance, tap the pan gently on the counter twice after pouring the batter to release air bubbles. If cracks appear after cooling, cover with extra buttercream or chocolate ganache to disguise them.
How do I store leftovers?
Cover tightly with plastic wrap or an airtight container and store at room temperature for up to 3 days. For longer storage, freeze the fully assembled cake (without frosting) for 3 months. Thaw overnight in the fridge, then bring to room temperature before serving. The white chocolate chips may soften slightly when frozen, but they’ll harden again at room temperature.
Can I substitute white chocolate chips?
Use 1.5 cups milk chocolate chips for a richer flavor or 1.5 cups dark chocolate chunks (60% cocoa) for depth. For a nutty twist, swap in 1 cup toasted pecans or walnuts. Just melt any solid chocolate chips in 30-second microwave bursts (stirring between bursts) to prevent burning. The texture will be slightly different but still delicious.
What’s the best way to level the cake?
Use a serrated knife or cake leveler for clean cuts. Dip the blade in hot water, wipe dry, and press firmly at a slight angle. For a perfectly flat top, level the cake 1 hour after baking when it’s fully cooled but still slightly warm. The knife should glide through the cake with minimal resistance. Save the leftover cake scraps for truffles or cake pops!
