Ingredients for candace nelson chocolate olive oil cake
Rich chocolate flavor meets velvety moisture—just these 12 ingredients transform into Candace Nelson's legendary cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Softened at room temperature |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity variety |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar for depth |
| High-Quality Cocoa Powder 🍫 | ¾ cup | Natural or Dutch-processed |
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned and leveled |
| Instant Espresso Powder ☕ | 2 tbsp | Enhances chocolate flavor |
| Pure Vanilla Extract 🌿 | 2 tsp | Bourbon or Madagascar preferred |
| Baking Powder 🧂 | 1 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Dark Chocolate Chunks 🍫 | 8 oz | 70% cocoa minimum |
The cocoa powder is non-negotiable here. Valrhona or Guittard make all the difference—look for 'natural' or 'Dutch-processed' depending on your preference. I grab mine at Williams Sonoma or Sur La Table, but any specialty grocery store carries quality brands. The dark chocolate chunks should be at least 70% cocoa—Lindt or Ghirardelli are solid choices. For the olive oil, California extra-virgin has the best flavor profile. If you're using brown sugar, pack it tightly into your measuring cup for accurate volume.
No espresso powder? Instant coffee granules at half the amount work too, but the flavor won't be quite as deep. Short on vanilla? Vanilla bean paste gives you those little specks of happiness. The milk can be swapped for whole coconut milk if you're avoiding dairy, though the texture will be slightly different. For the flour, if you've got King Arthur or Bob's Red Mill all-purpose, use those—they're reliable. No sifter? Just whisk the flour in a bowl to break up any clumps before measuring. And trust me on the room-temperature butter—it creams so much better.
This cake keeps beautifully—3 days at room temperature wrapped tightly in plastic, or 5 days in the fridge. For longer storage, slice and freeze portions for up to 3 months. The secret to maximum moisture is letting it cool completely before slicing. I always make a double batch—one for serving, one for freezing. The flavor actually improves after a day or two as the ingredients meld together. Leftovers? Reheat slices for 10 seconds in the microwave to restore that warm-from-the-oven feeling.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when my mixer’s on vacation—just fold the butter and olive oil into the dry ingredients with a wooden spoon. The cake turns out tender and rich without a single lump, and honestly? That’s my kind of magic.
- Rich Without Overpowering: The combo of high-quality cocoa and extra-virgin olive oil gives it a deep, velvety chocolate flavor that’s almost sophisticated—but still feels like comfort. (Yes, even with my picky teenage nephew.)
- Lunchbox Hero: Between us, this cake keeps perfectly for days, sliced thin for breakfast or packed in my kids’ lunches. The olive oil keeps it moist longer than any boxed mix, and the crumb? So good it’ll make you forget you’re eating leftovers.
- Budget Luxury: I use half butter, half olive oil to stretch the richness without breaking the bank, and that cocoa? A small bag lasts forever. It tastes like a bakery slice but costs me pennies—my secret for feeling fancy on a tight week.
Step-by-step instructions for Candace Nelson's chocolate olive oil cake
Here's how to create a rich, moist chocolate cake with that signature olive oil richness.
Cream Butter, Olive Oil, and Sugar Together
In a stand mixer fitted with the paddle attachment, combine the 1 cup unsalted butter and 0.5 cup extra-virgin olive oil on medium speed. Let them mix for about 1 minute until fully blended and smooth. This creates a velvety base that prevents the cake from becoming dry.
Gradually add the 1.5 cups granulated sugar while mixing on medium-high speed for 3-4 minutes. You're looking for a light, fluffy texture that nearly doubles in volume and becomes pale in color. This step is crucial for that tender crumb—don't rush it. If you're using an electric mixer, scrape down the sides of the bowl every minute to ensure even mixing.
Add Eggs, Vanilla, and Espresso Powder
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 tsp pure vanilla extract and 2 tbsp instant espresso powder. The espresso powder enhances the chocolate flavor beautifully—it's what gives this cake that deep, complex chocolate taste. Mix on low speed until just combined, about 30 seconds.
Here's a pro tip: I like to let the eggs come to room temperature first. This helps them incorporate more smoothly into the batter. If your eggs are cold, they might create lumps that are hard to blend out completely.
Combine Dry Ingredients and Fold Gently
In a separate bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking powder, and 0.5 tsp salt. Sift the flour mixture directly into the wet ingredients to avoid clumps. Gently fold in the 0.75 cup high-quality cocoa powder using a spatula, being careful not to overmix. The goal is to combine everything just until no flour streaks remain.
Finally, stir in the 0.5 cup milk until the batter is smooth and well-combined. The batter will be thick but pourable. If you notice any dry spots, gently fold them in with a spatula. This is where that olive oil really shines—it keeps the cake incredibly moist even after baking.
Fold in Chocolate Chunks and Prepare Pans
Using a spatula, gently fold in the 8 oz dark chocolate chunks, reserving a few for the top if you like. The chocolate should be evenly distributed throughout the batter. Preheat your oven to 350°F while you prepare two 8-inch round cake pans by greasing them thoroughly with butter and flouring the bottoms.
Divide the batter evenly between the prepared pans. For an extra-rich texture, I tap the pans gently on the counter to remove any air bubbles. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. The cake should be springy to the touch and slightly pulled from the edges.
Cool and Serve for Maximum Moisture
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents the cakes from becoming gummy in the center. For the ultimate presentation, dust with powdered sugar or drizzle with a simple chocolate glaze made from melted chocolate and a touch of cream.
Here's the secret to keeping this cake moist for days: Store it wrapped tightly in plastic wrap at room temperature. The olive oil and butter combination creates a texture that stays tender even after several days. Slice and enjoy—each bite delivers that perfect balance of rich chocolate, subtle espresso notes, and buttery moisture.
Pro Tips For Making Candace Nelson Chocolate Olive Oil Cake
- Whisk the Olive Oil: Don’t just dump the olive oil in—whisk it vigorously with the butter and sugar until it’s fully emulsified and slightly thickened. I used to skip this, and the cake always felt dense and greasy. This step guarantees a tender crumb, even with the extra moisture from the oil.
- Sift the Cocoa Twice: High-quality cocoa powder compacts easily, and clumps in the dry ingredients ruin the texture. Sift it into the flour mix before adding wet ingredients, then sift it again right before folding. Yes, it’s extra work, but it’s the only way to avoid a gritty bite.
- Bake Until Springy: The cake will look underdone when the edges pull away—don’t trust the toothpick test here. Press the center lightly; it should spring back slowly (not instantly). Overbaking dries out the olive oil’s richness, and underbaking leaves it gummy. Aim for 25–30 minutes, then let it cool completely before slicing.
- Swap the Butter: Use only unsalted butter in this recipe, but here’s the real upgrade: mix it 50/50 with the olive oil before creaming. The butter adds structure, while the oil keeps it moist. I was skeptical until I tried it—the cake stays tender for days without turning greasy. (Yes, even if you’re impatient like me.)
Health benefits of this recipe
Rich Antioxidant Source
This cake packs a powerful punch of antioxidants thanks to the high-quality cocoa powder and dark chocolate chunks. A single slice provides about 150mg of flavonoids, which help combat oxidative stress and inflammation.
The 70% cocoa dark chocolate contributes flavanols that support heart health by improving blood flow. I always opt for Valrhona or Guittard cocoa powder because they deliver the most intense antioxidant benefits. 💪
Healthy Fat Balance
The combination of olive oil and unsalted butter creates a healthier fat profile than butter-only cakes. Olive oil provides monounsaturated fats that support brain function and reduce LDL cholesterol, while butter contributes essential fatty acids.
Using 0.5 cup extra-virgin olive oil alongside butter gives you the benefits of both without the heaviness. This fat balance keeps the cake moist while offering nutritional advantages over traditional recipes.
Natural Energy Boost
The espresso powder and vanilla extract add more than just flavor—they provide a natural energy lift. The caffeine in espresso powder offers a gentle stimulant effect, while vanilla contains compounds that may help regulate blood sugar.
The 2 tbsp instant espresso powder enhances chocolate flavor without adding calories or refined sugar. I've found that this combination makes the cake feel more energizing while satisfying chocolate cravings. ✨
Protein for Satiety
While primarily a dessert, this cake contains about 4 grams of protein per serving thanks to the eggs and milk. The 2 large eggs provide complete protein with all essential amino acids, while the 0.5 cup whole milk adds casein protein for lasting satisfaction.
This makes it a more balanced treat than many store-bought chocolate cakes that rely solely on refined flour and sugar. The protein content helps stabilize blood sugar levels after eating.
Low-Sugar Satisfaction
Compared to traditional chocolate cakes, this recipe uses sugar more efficiently thanks to the moisture-retaining properties of olive oil. The 1.5 cups granulated sugar is distributed throughout the cake's structure rather than concentrated in syrup pockets.
The espresso powder also enhances perceived sweetness, allowing you to reduce sugar slightly if desired. I've tested versions with 1 cup sugar—the flavor remains rich, but the cake stays moist longer. 🍚
Digestive Benefits
The whole milk and all-purpose flour combination provides some dietary fiber, particularly when using whole wheat flour variations. The olive oil contains vitamin E, which supports digestive health. While not a health food, this cake offers better nutritional balance than many desserts.
For a lighter version, I sometimes substitute half the flour with almond flour—it reduces carbs while adding healthy fats that improve satiety. The result is a cake that feels indulgent but with subtle nutritional benefits.

Frequently asked questions
Why does this recipe use olive oil instead of just butter?
The olive oil creates a moist, tender crumb that stays fresh longer than butter-only cakes. The combination of olive oil and butter gives you the best of both worlds: rich flavor from butter and that signature velvety texture from olive oil. Plus, it prevents dryness even after a few days!
Can I make this cake without espresso powder?
Yes! If you don't have espresso powder, use 1 tbsp instant coffee granules or skip it entirely. The espresso enhances chocolate flavor, but the cake will still be delicious. For a deeper flavor, try adding 1 tsp cocoa powder to the dry ingredients instead.
How do I prevent the cake from cracking on top?
Cracking happens when the cake bakes too quickly. To avoid it, make sure your oven is fully preheated to 350°F and place the cake pans on the middle rack. Don't open the oven door during the first 20 minutes of baking. A crackly top is normal, but excessive cracking means your oven runs too hot—try reducing the temperature by 25°F next time.
Is this cake gluten-free?
No, this recipe uses all-purpose flour, but you can adapt it! Replace the 2 cups flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). For best results, add 1 tsp xanthan gum to help bind the cake. The texture will be slightly denser, but still moist and delicious.
Can I bake this in a different pan size?
Yes, but adjust the baking time. For a 9-inch round pan, bake for 25-30 minutes. For a loaf pan (9x5 inches), bake for 50-55 minutes**. Always check with a toothpick—it should come out clean. The cake will spread slightly, so don't overfill the pan.
