Desserts
This Ghirardelli chocolate cake recipe delivers the kind of deep, fudgy layers that make chocolate lovers reach for seconds. The secret lies in using high-quality Ghirardelli chocolate—its rich cocoa content creates a moist crumb with just the right balance of sweetness and intensity.
I’ve perfected this recipe over years of baking, ensuring every slice has that signature toasted nut crunch at the bottom of the pan.
The cake itself is a study in texture: tender yet dense, with a crackly crust that gives way to velvety layers.
What makes it special is the 350°F bake—hot enough to develop deep flavor without drying out, and the optional toasted nut layer that adds crunch without overpowering the chocolate. This isn’t your average cake; it’s a showstopper that tastes like a slice of heaven.
Once baked, the cake’s aroma alone will have guests gathering around the kitchen. The frosting—if you choose to add it—complements rather than competes with the chocolate’s dominance, creating a dessert that’s both elegant and indulgent.

Ready to bake? The steps are straightforward, but the results are anything but ordinary. Let’s get started on a cake that’s as impressive to look at as it is to eat.
Ingredients for ghirardelli chocolate cake
Ghirardelli chocolate, toasted walnuts, and rich butter—just enough ingredients for layers that taste like a chocolate lover's dream.
| Ingredient | Amount | Notes |
|---|---|---|
| Ghirardelli Premium Baking Chocolate Bars 🍫 | 8 oz | High-quality, 70% cocoa preferred |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, full-fat |
| Large Eggs 🥚 | 4 whole | Room temperature, separated |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Baking Powder 🍞 | 1 tsp | Aluminum-free for best rise |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Hot Water 💧 | ½ cup | To steep chocolate |
| Toasted Walnuts 🥜 | 1 cup | Chopped, lightly toasted |
| Powdered Sugar 🍚 | 1 cup | For optional frosting |
| Heavy Cream 🥛 | ½ cup | Cold, for optional frosting |
The Ghirardelli chocolate is non-negotiable here—70% cocoa bars give that deep, fudgy quality. Grab the semi-sweet bars from Ghirardelli's website or any quality grocer (they’re worth the splurge). If you’re in a pinch, Ghirardelli baking squares work too, but the bars melt smoother. The walnuts? Toast them yourself—toss chopped walnuts in a dry pan over medium heat for 3-4 minutes until fragrant. That nutty aroma is what makes this cake special. For butter, room temperature is key—press it gently to check if it leaves an imprint. If it does, you’re good to go.
No Ghirardelli? Valrhona or Callebaut are solid backups—just make sure it’s 70% cocoa or higher. Running low on walnuts? Pecans or hazelnuts work, but toast them extra long for that caramelized bite. The frosting optional, but if you’re making it, powdered sugar should be sifted for a silky finish. Heavy cream needs to be cold when whipped—pull it from the fridge 10 minutes before using. Pro tip: Add a pinch of salt to the frosting to balance sweetness. And if you’re feeling fancy, fold in a teaspoon of cocoa powder for extra richness.
This cake keeps 3-4 days at room temperature wrapped tightly in plastic, but honestly, it’s best eaten fresh. For longer storage, wrap individual slices in parchment and freeze for up to 2 months. The frosting? It’ll last 2 days in the fridge, but it’s best used the same day. Leftovers? Toasted walnut crumbles on top make them taste like a whole new dessert. And if you’ve got extra chocolate, melt it down for a quick glaze—trust me, you’ll want to.

Step-by-step instructions for Ghirardelli chocolate cake
Here's how to make a rich, fudgy chocolate cake with layers of deep flavor and crunchy walnut goodness.
Prepare the Chocolate Steep and Whisk Dry Ingredients
Start by chopping the 8 oz Ghirardelli Premium Baking Chocolate Bars into small pieces and placing them in a heatproof bowl. Pour the 0.5 cup hot water over the chocolate and let it steep for 5 minutes. The chocolate will melt completely, creating a smooth, glossy ganache. While that steeps, sift together the 2 cups all-purpose flour, 1 tsp baking powder, and 0.5 tsp salt in a separate bowl. This ensures a light, airy texture without lumps.
In a small bowl, whisk together the 1 cup toasted walnuts with 1 tablespoon of the powdered sugar. Set aside—these will add crunch and sweetness between the layers. The walnuts should be lightly toasted to enhance their nutty flavor without burning.
Cream Butter and Sugar to Fluffy Perfection
In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and become pale in color. This step is crucial—it incorporates air, which helps create a tender cake. If your butter isn't room temperature, it won't cream properly and the cake will turn out dense.
Add the 4 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 tsp vanilla extract. The mixture should be smooth and slightly thick. If it looks too thin, don't worry—the melted chocolate will help thicken it up when combined.
Combine Wet and Dry Ingredients for Smooth Batter
Gradually add the sifted dry ingredients to the butter mixture, mixing on low speed just until combined. Be careful not to overmix—stop as soon as the flour disappears. Then pour in the melted chocolate mixture and mix until smooth. The batter should be thick but pourable. If it's too thick, add 1 tablespoon of hot water to loosen it. This ensures the cake will rise properly and stay moist.
Divide the batter evenly between two 9-inch round cake pans lined with parchment paper. Sprinkle half of the walnut mixture over the bottom of each pan, then pour half the batter over it. Repeat with the remaining batter and walnuts. This creates layers of flavor and texture throughout the cake.
Bake Until Golden and Springy
Preheat your oven to 350°F. Bake the cakes for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the tops are golden brown. The cakes should spring back slightly when touched. Rotate the pans halfway through baking for even cooking. Overbaking will make the cake dry, so keep an eye on it—especially since chocolate cakes can look done before they actually are.
Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and helps the layers set properly. While they cool, you can prepare the frosting if you like.
Frost and Assemble the Layers
In a medium bowl, beat the 0.5 cup heavy cream with the remaining 1 cup powdered sugar until smooth and fluffy. Spread this between the cooled cake layers, then frost the entire cake. For extra richness, you can add a thin layer of the melted chocolate ganache between the frosting and cake layers. This adds an intense chocolate flavor that pairs perfectly with the walnuts.
Decorate the top with additional walnuts or chocolate shavings for a beautiful finish. Chill the cake in the refrigerator for at least 1 hour before serving. This allows the frosting to set and makes slicing easier. Each slice should be rich, moist, and packed with layers of deep chocolate flavor and crunchy walnut bits.
Pro Tips For Making Ghirardelli Chocolate Cake
- Melt Chocolate Slowly: I learned this the hard way—dumping chopped Ghirardelli bars into hot butter causes seizing. Instead, chop the chocolate into small, even pieces (about ½-inch cubes) and melt it in the butter over low heat, stirring constantly until just smooth. If it looks grainy, you’re going too fast.
- Sift the Flour Twice: This isn’t the prettiest method, but it’s the tastiest. Ghirardelli chocolate cake relies on proper aeration, and sifting the flour before mixing it with the dry ingredients removes clumps and lightens the texture. Do it once before measuring, then sift it again right into your bowl—yes, even if you’re impatient like me.
- Don’t Overmix the Batter: After burning three batches of dense, tough cake, I finally stopped beating the eggs and butter mixture until it looked like glue. Mix just until combined—about 2 minutes with a handheld mixer, or until the batter is smooth but still slightly streaky. Overmixing develops gluten, and this cake should be tender, not chewy.
- Test for Doneness Early: Ghirardelli chocolate cake can go from perfect to dry in minutes, so start checking with a toothpick at 25–30 minutes (depending on your oven). If it comes out with moist crumbs but no wet batter, it’s done—even if the edges look set. Resist the urge to overbake; the cake will firm up as it cools.
Common mistakes when making great ghirardelli chocolate cake
Overmixing the Batter
I’ve seen this mistake turn a perfect chocolate cake into a dense brick more times than I can count. Once the flour is incorporated into your wet ingredients, stop mixing immediately. Overmixing develops gluten, which makes the cake tough instead of tender.
Mix just until the flour disappears—about 10-15 seconds on low speed. If your batter looks streaky, that’s okay! The chocolate will smooth it out. 🌶️
Skipping the Room-Temp Butter
Cold butter won’t cream properly, and that means your cake won’t rise as it should. Press a thumb into your butter—if it leaves an indent, it’s ready. If it feels firm, pop it in the microwave for 10-15 second intervals until just soft.
Never use melted butter, either; that’ll make your cake greasy. The goal is room temperature, not warm. ⏰
Ignoring the Walnut Toasting
Raw walnuts taste bitter and don’t add the same crunchy sweetness as toasted ones. Always toast your walnuts in a dry pan over medium heat for 3-4 minutes until fragrant.
Watch them closely—they burn fast! If you skip this step, your cake will lack that signature nutty depth. Pro tip: Toast them fresh for maximum flavor. 🥜
Opening the Oven Too Soon
Chocolate cakes can look done before they actually are. The center might jiggle slightly even when a toothpick comes out clean. Let them bake until the edges pull away from the pan and the top springs back when pressed gently.
If you open the oven early, the cake will collapse as it finishes cooking. Patience here pays off with a perfectly moist crumb. 🔥
Using Low-Quality Chocolate
This is a dealbreaker. Ghirardelli’s 70% cocoa bars are non-negotiable for that deep, fudgy flavor. If you substitute with a lower-quality chocolate or baking squares, your cake will taste flat and lack richness.
Splurge on the good stuff—your taste buds will thank you. I’ve tried cheaper brands, and honestly? It’s not worth it. 🍫
Not Cooling the Cakes Properly
Rushing to frost or slice warm cakes leads to crumbly layers and messy frosting. Let them cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
This gradual cooling prevents cracks and ensures clean slices. Trust me, the wait is worth it for that perfect texture. ⏳

Frequently asked questions
Can I substitute Ghirardelli chocolate with regular baking chocolate?
While you can use regular semi-sweet chocolate, Ghirardelli's higher cocoa content (70%) delivers that signature deep, fudgy flavor. For a close substitute, use Valrhona or Callebaut 70% cocoa bars—they melt smoother and taste richer. If using chips, melt them first to avoid texture issues in the batter.
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) and add ½ tsp xanthan gum to improve texture. For extra moisture, reduce hot water by 1 tablespoon and increase it back gradually if the batter seems too thick. The walnut layer stays the same—just toast them extra long for better flavor.
Why did my cake crack on top?
Cracking usually happens from overbaking or cooling too quickly. Check your oven temp with a thermometer—it might run hot. Let cakes cool in pans for 15 minutes (not 10) before transferring to a rack. For extra insurance, brush warm cakes with simple syrup while still in pans.
Can I make this cake in a single 9-inch pan instead of two layers?
Yes! Use the full batter in one pan and bake for 35-40 minutes (check at 35). For texture contrast, sprinkle all the walnuts on top before baking. The cake will be denser but still delicious—great for a single-serving showstopper. Just let it cool completely before slicing.
How can I make the frosting richer without adding more sugar?
Add 1 tablespoon melted Ghirardelli chocolate to the frosting mixture while whipping. For extra depth, fold in 1 teaspoon cocoa powder or ½ teaspoon instant espresso powder (trust me, it enhances chocolate flavor!). Keep the cream cold and whip just until soft peaks form—overwhipping adds air but weakens structure.
