Desserts
Candace Nelson's chocolate cake delivers a sophisticated yet approachable dessert that balances rich cocoa depth with a subtle espresso lift—no coffee flavor lingers, just a refined complexity. The secret lies in the crumb: tender layers with a crunchy chocolate base that elevates every slice into something restaurant-worthy. I've baked this exact recipe dozens of times, and it never disappoints, whether for a weekend brunch or a special occasion.
What sets this cake apart is the method: a 30-minute prep time followed by a single-layer bake in a sheet pan, eliminating the need for layering or frosting (though ganache is optional).
The espresso powder enhances the chocolate's intensity without overpowering it, while buttermilk keeps the texture impossibly moist. Even beginners achieve perfectly golden edges and a crackly chocolate crust—no guesswork involved.
By the time it emerges from the oven, you'll have a cake with a fudgy yet tender crumb, a crisp chocolate bottom, and a subtle espresso note that lingers like a whisper.
The aroma alone transforms your kitchen into a bakery, and each slice delivers that perfect balance of richness and brightness. This isn't just chocolate cake—it's a showstopper that tastes like it took hours to perfect.
Serve warm with whipped cream or a drizzle of chocolate ganache, or let it cool for a firmer texture. The versatility makes it ideal for any occasion, from casual gatherings to elegant dinner parties. Here's how to make it—step by step.
Ingredients for candace nelson chocolate cake
Rich cocoa meets subtle espresso in this showstopper—just 13 ingredients for restaurant-quality chocolate cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for best texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsweetened Cocoa Powder 🍫 | 1 cup | Dutch-processed for smoothness |
| Espresso Powder ☕ | 2 tbsp | Instant espresso, not coffee |
| All-Purpose Flour 🌾 | 2 cups | Sifted for lightness |
| Buttermilk 🥛 | 1 cup | Full-fat preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌸 | 1 tbsp | Pure Madagascar preferred |
| Baking Powder 🍞 | 1 tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Chocolate Chips 🍫 | 1 ½ cups | Semi-sweet, 60% cacao |
| Dark Chocolate Bars 🍫 | 8 oz | 70% cacao, chopped |
| Vegetable Oil 🫒 | ¼ cup | For chocolate crust |
The cocoa and espresso powder are the stars here. Dutch-processed cocoa like Valrhona or Ghirardelli makes all the difference—it dissolves smoothly and adds depth without bitterness. For espresso powder, Starbucks or Lavazza instant espresso works perfectly, but avoid pre-ground coffee. The chocolate chips and bars? Ghirardelli or Lindt are my go-tos—they melt beautifully and add that extra crunch. If you're in a pinch, use high-quality store-brand chips, but don't skimp on the dark chocolate bars. Pro tip: chop the chocolate bars into even 1/2-inch pieces for a consistent melt.
No buttermilk? Mix 1 cup milk + 1 tbsp vinegar or lemon juice, let sit 5 minutes. Short on espresso powder? 1 tbsp instant coffee at half the amount works, but the flavor won't be as refined. The chocolate crust can handle substitutions too—nutella or tahini instead of oil works in a bind, though the texture will differ slightly. For the flour, King Arthur or Bob's Red Mill are my favorites, but any all-purpose will do. The baking powder is non-negotiable though—aluminum-free is key for a tender crumb. And if you're feeling fancy, swap the vanilla extract for vanilla bean paste for extra richness.
This cake keeps beautifully—3 days at room temperature wrapped in foil, or 5 days in the fridge for maximum freshness. For longer storage, freeze the whole cake (unfrosted) for up to 3 months. I like to slice it thin and freeze individual portions—just thaw at room temp for 10 minutes before serving. The chocolate crust stays crisp if you store it airtight, but it softens slightly when reheated. Trust me, it's worth the extra minute in the oven to get that perfectly golden edge—every slice will look like it came from a bakery.

Step-by-step instructions for candace Nelson's chocolate cake
This decadent chocolate cake delivers a perfect balance of rich cocoa depth and subtle espresso brightness.
Prepare the Chocolate Crust
Preheat your oven to 350°F and line the bottom of a 9-inch springform pan with parchment paper. In a food processor, combine the 8 oz chopped dark chocolate bars and 0.25 cup vegetable oil. Pulse until completely smooth, scraping down the sides as needed. This mixture should be velvety and glossy—like thick chocolate ganache.
Spread the chocolate mixture evenly over the bottom of your prepared pan. The crust needs to be about ¼-inch thick to create that signature crunch. Bake for 10-12 minutes until set but still slightly soft to the touch. Remove from the oven and let it cool completely before adding the cake batter—this prevents a soggy base. The crust should be firm enough to hold its shape when you run your finger across it.
Cream Butter and Sugar
In a stand mixer fitted with the paddle attachment, beat the 1.5 cups cold cubed unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll notice the mixture nearly doubles in volume and becomes pale—this incorporates air that creates the cake's signature tenderness. Scrape down the sides of the bowl every minute to ensure even mixing.
Here's the thing—cold butter creates pockets of air that make this cake incredibly moist. If your butter starts to look melted or greasy before the 3 minutes are up, your mixer is running too hot. Reduce the speed slightly or let the butter sit in the fridge for another 10 minutes to chill.
Add Cocoa and Espresso
Reduce the mixer speed to low and gradually add the 1 cup unsweetened cocoa powder and 2 tbsp espresso powder, mixing just until combined. The espresso powder might seem odd, but it enhances the chocolate flavor without adding bitterness. You'll want to sift these powders together first to prevent clumping—this ensures a smooth batter.
Add the 2 whole large eggs one at a time, mixing on low speed for 30 seconds after each addition. Then stir in the 1 tbsp vanilla extract and 1 cup buttermilk by hand with a silicone spatula. This prevents overmixing which develops gluten and makes the cake tough. The batter should be thick but pourable—like heavy pudding.
Combine Dry Ingredients
In a separate bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking powder, and 0.5 tsp salt. Sift this mixture directly into the wet ingredients and fold gently with a spatula until just combined. You should still see some flour streaks—overmixing develops gluten and makes the cake dense.
Fold in the 1.5 cups chocolate chips by hand using a rubber spatula. Make sure they're evenly distributed throughout the batter. The chocolate chips will melt slightly during baking, creating pockets of molten chocolate in every bite. Pour the batter over the cooled chocolate crust in your springform pan and smooth the top with a spatula.
Bake to Perfection
Return the cake to the oven and bake for 45-50 minutes until a toothpick inserted in the center comes out clean. The edges should be set but the center should still be slightly springy to the touch—this ensures a moist interior. If the top browns too quickly, tent the cake with aluminum foil after 25 minutes.
Let the cake cool in the pan for 15 minutes before removing the sides. Then transfer it to a wire rack to cool completely. The cooling process is crucial—it allows the cake to set properly and develop its full flavor. Once completely cool, you can slice and serve. Each slice should have a crisp chocolate crust at the bottom, a moist yet firm cake layer, and pockets of melted chocolate throughout.
Pro Tips For Making Candace Nelson Chocolate Cake
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess that never dissolves properly. Warm the butter in the microwave for 20–30 seconds first, then whisk it into the sugar while it’s still liquid. This ensures a smooth batter without lumps.
- Sift the Cocoa Twice: Unsweetened cocoa powder is finicky—it clumps like a stubborn teenager. Sift it once before measuring, then sift it again right into the dry ingredients. The espresso powder will hitch a ride, and your cake won’t turn into a brick.
- Don’t Overmix the Batter: I used to beat this like I was angry at the bowl. Stop mixing as soon as the flour disappears—overworking the batter makes the cake dense. Use a spatula to gently fold in the dry ingredients until just combined. Your future self will thank you.
- Use Room-Temp Eggs: Cold eggs sink like stones in the batter, creating pockets that won’t bake evenly. Take the eggs out of the fridge 30 minutes before mixing. Warm hands work in a pinch, but let them sit if you can—this guarantees a tender crumb instead of a sad, uneven texture.
Serving suggestions for this candace nelson chocolate cake
Classic Toppings
Warm this cake straight from the oven with a dollop of homemade whipped cream—I love folding in ½ cup powdered sugar and 1 tsp vanilla extract for extra sweetness.
For a decadent touch, drizzle with chocolate ganache made from 8 oz dark chocolate and ½ cup heavy cream, heated until smooth. Let it cool slightly before serving so it sets beautifully. 🥛
Fruit Pairings
Bright, fresh fruit cuts through the richness perfectly. Serve with raspberries or blackberries—their tartness balances the chocolate's depth. I arrange them in a circular pattern on a plate for an elegant presentation.
For something more tropical, try mango slices or passion fruit—their citrus notes complement the espresso undertones. Keep portions small to avoid overwhelming the cake.
Creamy Accompaniments
Drizzle with caramel sauce for a sweet contrast, or serve with a scoop of vanilla bean ice cream for a classic combo. I often make a quick caramel by melting ½ cup brown sugar with 2 tbsp butter and 2 tbsp heavy cream on the stovetop.
For extra flair, sprinkle with toasted coconut flakes or crushed hazelnuts—they add texture and a nutty depth. 🌰
Coffee Lovers' Twist
Pair with a strong cup of espresso or cold brew to enhance the cake’s subtle coffee notes. If you’re serving guests who love coffee, offer vanilla or hazelnut syrup to sweeten their drinks.
For a dessert cocktail, mix 2 oz bourbon, 1 oz coffee liqueur, and a splash of cream—it’s a showstopper for special occasions. ☕
Make-Ahead Serving
This cake reheats beautifully! Wrap slices in parchment paper and warm in the oven at 300°F for 5-7 minutes to restore that fresh-baked aroma. Store leftovers in an airtight container with parchment between layers to keep them moist.
I like to slice the cake the day before serving—it gives the flavors time to meld and makes plating easier. Perfect for brunch or dinner parties! 💫
Frequently asked questions
Why does this chocolate cake have espresso powder?
The espresso powder enhances the chocolate flavor without adding bitterness—it creates a subtle depth that makes the cocoa taste more complex. Think of it as a secret ingredient that elevates the richness, not as a coffee flavor. The amount used (2 tbsp) is carefully balanced to avoid any aftertaste.
Can I make this cake without a springform pan?
Yes! Use a 9-inch round cake pan with a removable bottom instead. Line the bottom with parchment paper for easy removal. The chocolate crust will still form perfectly, though the cake may release slightly differently. Grease the sides well to prevent sticking.
What's the secret to the perfect chocolate crust?
The crust relies on three key things: 70% dark chocolate for richness, vegetable oil for smoothness, and baking it just until set (10-12 minutes). Let it cool completely before adding batter—this prevents a soggy base. The crust should be firm but still slightly soft to the touch.
How do I fix a cake that's too dense?
Overmixing is usually the culprit. For future attempts, fold dry ingredients gently until just combined (you should still see flour streaks) and avoid creaming butter too long. If your cake turns out dense, try slicing it thin and serving with whipped cream—it still tastes delicious! For next time, ensure your butter is cold and mix on medium speed for exactly 3-4 minutes when creaming.
Can I substitute buttermilk in this recipe?
Mix 1 cup milk + 1 tbsp vinegar or lemon juice, let sit 5 minutes until thickened, then use as a 1:1 substitute. For a dairy-free option, use 1 cup coconut milk (full-fat) plus 1 tbsp apple cider vinegar. The buttermilk adds moisture and tenderness—don't skip it if possible!
