Desserts
Candace Nelson’s chocolate olive oil cake delivers unexpected depth with its signature coffee-infused layers—rich, moist, and sophisticated enough for special occasions but simple enough for weeknight cravings. The secret lies in olive oil’s ability to create tender crumb while coffee extract deepens the chocolate flavor without overpowering it.
I’ve baked this recipe countless times, and it never fails to impress with its fudgy texture and perfect rise.
What sets this cake apart is the balance: dark chocolate for intensity, buttermilk for moisture, and a precise baking time that yields a crackly top without drying out the interior.
The coffee isn’t an afterthought—it’s baked into the batter, giving each slice a subtle, aromatic complexity that pairs beautifully with whipped cream or a dusting of cocoa powder. Every layer stays perfectly moist for days, making it ideal for meal prep or gifting.
The process is straightforward but requires attention to detail, particularly the 350°F oven temperature and the 50-minute bake time. You’ll need to let the cake cool gradually to maintain its structure, then slice it while still warm for that ideal balance of firmness and tenderness.
The result? A cake that’s decadent yet approachable, with a flavor profile that feels both classic and surprisingly modern.
Whether you’re serving it at a dinner party or simply indulging in a solo slice, this recipe delivers restaurant-quality results with minimal effort. The key is patience—allowing the cake to cool completely before serving ensures clean slices and maximum flavor impact. Ready to bake?
Ingredients for candace nelson chocolate olive oil cake
Eight essential ingredients—plus a few secret touches—that create Candace Nelson’s legendary moist chocolate cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Extra-Virgin Olive Oil 🫒 | 1 cup | High-quality, fruity variety for richness |
| Granulated Sugar 🍚 | 2 cups | Light brown sugar for subtle caramel notes |
| Unsalted Butter 🧈 | 1 cup | Room temperature for smooth batter |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon preferred |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed for smooth flavor |
| Baking Powder 🍞 | 1 tsp | Freshly opened for lift |
| Salt 🧂 | ½ tsp | Fine sea salt for balance |
| Instant Espresso Powder ☕ | 2 tbsp | Pure, finely ground for depth |
| Buttermilk 🥛 | 1 cup | Room temperature for moisture |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cocoa or higher |
| Coffee Extract ☕ | 1 tbsp | Pure, not imitation |
The olive oil is non-negotiable here—look for extra-virgin with a fruity, peppery finish at specialty grocers like Whole Foods or Trader Joe's. The dark chocolate chips should be at least 70% cocoa for that rich, complex flavor. I always grab Valrhona or Ghirardelli when I’m feeling fancy, but Ghirardelli baking squares work perfectly for weeknight baking. The instant espresso powder? Starbucks or Nescafé are reliable brands—just make sure it’s pure, no fillers. Coffee extract is trickier to find, but Walmart or Amazon usually carry it. The buttermilk needs to be room temperature for the best texture—if yours is cold, let it sit out for 30 minutes.
No buttermilk? Mix 1 tablespoon vinegar or lemon juice with 1 cup milk—it works perfectly. Short on coffee extract? Double the espresso powder and add 1 teaspoon hot water to dissolve it. Want to skip the espresso entirely? Add 1 teaspoon instant coffee granules instead. The vanilla extract matters—Madagascar bourbon gives the best depth, but imitation will work in a pinch. For the flour, King Arthur or Bob’s Red Mill brands are my go-tos—they’re consistent and reliable. If you’re using a different brand of cocoa powder, check the package—some are more concentrated than others, so you might need to adjust slightly.
Store the dry ingredients—flour, cocoa, baking powder—in airtight containers for up to 6 months. The olive oil and butter should be kept in the fridge after opening to prevent rancidity. The cake itself? Best eaten within 3 days for maximum moisture, but it freezes beautifully for up to 3 months. Wrap tightly in plastic wrap, then foil, and thaw overnight in the fridge before serving. Pro tip: Slice it warm—that’s when it’s at its peak tenderness and fudgy perfection.

Step-by-step instructions for Candace Nelson’s chocolate olive oil cake
Here's how to create ultra-moist layers with that signature coffee depth—no dry crumbs in sight.
Prepare the Coffee-Infused Olive Oil Base
In a small bowl, whisk together the 1 cup Extra-Virgin Olive Oil, 2 cups Granulated Sugar, 1 tbsp Coffee Extract, and 2 tsp Vanilla Extract until fully combined. This step creates the cake's signature moisture and depth—don't skip the coffee extract, as it's what gives this cake its professional-level complexity. Let the mixture sit for 5 minutes at room temperature to allow the flavors to meld.
The olive oil here does double duty as both fat and flavor carrier, creating that signature tender crumb. If you're using a particularly robust olive oil, you might notice a subtle fruity note that pairs beautifully with the chocolate. This is your foundation, so take your time blending everything evenly.
Combine Wet Ingredients and Whisk with Eggs
In a separate large mixing bowl, melt the 1 cup Unsalted Butter in the microwave in 20-second intervals, stirring between each, until completely smooth. Add the butter to the olive oil mixture and whisk until fully incorporated. Then, add the 2 whole Large Eggs, one at a time, whisking vigorously after each addition until the mixture is completely smooth and glossy.
This is where the magic happens—the butter and eggs create an emulsion that will give your cake that signature ultra-moist texture. The mixture should be thick but pourable at this stage. If you notice any lumps, strain the mixture through a fine-mesh sieve to ensure a silky batter. The goal is to create a batter that's just thick enough to hold its shape when poured but still flows smoothly.
Sift and Fold in Dry Ingredients
In a medium bowl, sift together the 2 cups All-Purpose Flour, 0.75 cup Unsweetened Cocoa Powder, 1 tsp Baking Powder, 0.5 tsp Salt, and 2 tbsp Instant Espresso Powder. Gently fold this dry mixture into the wet ingredients using a spatula, mixing just until combined—overmixing will develop gluten and make your cake dense. Then, fold in the 1 cup Buttermilk and 1.5 cups Dark Chocolate Chips until evenly distributed.
The key here is gentle folding to maintain air pockets created by the baking powder. You'll know you've done it right when the batter has a marbled appearance with chocolate chips evenly dispersed. The buttermilk adds that signature tang that balances the richness of the olive oil and chocolate. Don't worry if the batter looks thick—it will come together perfectly when baked.
Bake in Prepared Pans for Even Rise
Preheat your oven to 350°F. Grease two 8-inch round cake pans with olive oil and line the bottoms with parchment paper. Divide the batter evenly between the pans and smooth the tops with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
Here's where precision matters—the cake should be just set in the center but still slightly springy to the touch. The olive oil and butter combination means this cake will stay moist even after cooling, so don't overbake. If the tops are browning too quickly, tent the pans with aluminum foil. The goal is golden brown edges with a domed center that's just set.
Cool and Layer for Maximum Moisture
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. Once cooled, level the tops if needed with a serrated knife. For the ultimate moisture, brush each layer with a simple glaze made by whisking together 2 tbsp of the reserved olive oil with 1 tbsp powdered sugar and 1 tsp vanilla extract.
This glaze isn't just for show—it adds an extra layer of richness and helps seal in moisture. Assemble the layers with a thin layer of whipped cream or more of that olive oil glaze if you prefer. The coffee and chocolate flavors will sing through each bite, creating that perfect balance of richness and depth that makes this cake truly special. Serve within 24 hours for the best texture and flavor experience.
Pro Tips For Making Candace Nelson Chocolate Olive Oil Cake
- Whisk Eggs Cold: Pull the eggs straight from the fridge—room temperature eggs trap air and make this cake dense. I used to bring them out 30 minutes early, but that’s overkill; just whisk them right after cracking. The olive oil in this recipe needs cold eggs to emulsify properly, or you’ll end up with a greasy mess instead of a tender crumb.
- Measure Olive Oil Right: Use a kitchen scale for the olive oil—1/4 cup isn’t always 60ml. A little too much, and the cake turns oily; too little, and it dries out. I learned this after my first batch tasted like a Mediterranean salad instead of a rich chocolate cake. Weigh it to 60g for precision, especially if you’re using a fruity EVOO (the flavor matters more than you’d think).
- Don’t Overmix the Batter: Fold in the dry ingredients just until combined—lumps are fine, but don’t beat this like a soufflé. The butter and olive oil are heavy enough to handle a little roughness. Overmixing develops gluten, and this cake will turn tough instead of velvety. Stop when the flour’s mostly gone, then trust the oven to do the rest.
- Test with a Toothpick Twice: The cake pulls away from the pan early but stays slightly underdone inside. Wait until the toothpick comes out with just a few moist crumbs (not wet batter), then tent with foil and let it rest 10 minutes. Cutting it too soon makes it gummy—trust me, I’ve ruined plenty this way. The center firms up as it cools.
Health benefits of this dish
Rich Chocolate Benefits
This cake delivers antioxidant power from dark chocolate and cocoa powder—both packed with flavonoids that support heart health and reduce inflammation. A single slice provides about 150mg of flavonoids, equivalent to drinking two cups of black tea.
The 70% cocoa chocolate chips add extra polyphenols that help lower blood pressure naturally. 💪
Olive Oil Advantages
The extra-virgin olive oil isn't just for moisture—it's a heart-healthy fat rich in monounsaturated fats that improve cholesterol levels. One cup provides 14 grams of healthy fats without the saturated fat found in butter-based cakes.
The fruity, peppery notes also enhance flavor without added sugar. I always choose cold-pressed olive oil for maximum nutritional benefits.
Coffee's Cognitive Boost
The coffee extract and instant espresso powder aren't just for flavor—they contain caffeine and chlorogenic acid, compounds that improve focus and metabolism. A moderate dose (about 50mg caffeine per slice) can enhance alertness without the jitters of coffee drinks.
The antioxidant-rich chlorogenic acid also supports liver function and blood sugar regulation. Perfect for an energy-boosting dessert!
Balanced Nutrition
While this is a dessert, it's surprisingly nutrient-dense compared to traditional chocolate cakes. The buttermilk adds calcium and vitamin B12, while the eggs contribute high-quality protein (about 6 grams per slice).
The whole grain flour (if using) would add extra fiber, though all-purpose flour is used here for maximum tenderness. It's a guilt-free indulgence when enjoyed in moderation.
Moisture Without Guilt
The olive oil and buttermilk combination creates incredible moisture without needing excessive sugar. Each slice contains about 25 grams of sugar—half of what you'd find in many boxed cake mixes.
The natural sweetness from the olive oil and coffee extract means you can reduce sugar by 1-2 tablespoons if desired without sacrificing flavor. A win for both taste and nutrition! ✨
Nutrition facts
Frequently asked questions
Can I substitute butter for olive oil in this recipe?
The olive oil is essential for the cake's signature moist texture—it creates a tender crumb that butter can't replicate. However, if you must substitute, use 1 cup melted coconut oil (for a neutral flavor) or ¾ cup vegetable oil. The coffee and chocolate flavors will still shine, but the texture will be slightly denser. Never use melted butter as a 1:1 replacement, as it lacks the moisture properties of olive oil.
Why does this cake have coffee in it?
The coffee isn't just for flavor—it enhances the chocolate's depth and balances the richness of the olive oil. The instant espresso powder and coffee extract create a subtle, aromatic complexity that makes each bite more interesting. Think of it as the secret weapon that elevates this from a simple chocolate cake to something truly special. You'll notice the difference immediately when you taste it!
How do I prevent my cake from cracking on top?
Cracking happens when the cake cools too quickly. To avoid it, bake at 350°F and don't overbake—the center should be just set when a toothpick comes out with moist crumbs. After removing from the oven, let the cake cool in its pan for 10 minutes before transferring to a rack. If cracks appear, simply brush them with the olive oil glaze to restore moisture and beauty.
Can I make this cake in a single 9-inch pan instead of two 8-inch pans?
Yes, but expect a thinner, flatter cake. For best results, use a 9x2-inch round pan and reduce the baking time to 25-30 minutes. The texture will be the same, but the layers won't be as dramatic. If you prefer a single-serving cake, consider dividing the batter between two 6-inch pans instead—this gives you two perfect mini cakes with the same rich flavor.
How long will this cake stay fresh, and can I freeze it?
This cake stays moist for up to 3 days at room temperature when stored in an airtight container. For longer storage, wrap each layer tightly in plastic wrap, then foil, and freeze for up to 3 months. Thaw overnight in the fridge before serving. The olive oil and buttermilk combination keeps it incredibly fresh—unlike many cakes that dry out quickly.
