This almond flour olive oil cake delivers a moist crumb and bright citrus notes without dairy or eggs—perfect for vegan baking. The secret lies in properly hydrating the almond flour and using high-quality extra-virgin olive oil for richness.
I developed this recipe after years of testing gluten-free alternatives that often turned out dry or crumbly.
What sets this cake apart is the combination of almond flour's natural moisture retention and olive oil's ability to create a tender, velvety texture. The citrus zest adds a refreshing contrast to the nutty base, while the olive oil infuses subtle fruity notes.
Unlike many vegan cakes, this one doesn't require special ingredients or techniques—just patience during mixing.
By the time it emerges from the oven, you'll have a golden-domed cake with a fine, even crumb that's neither dense nor crumbly. The citrus aroma fills your kitchen, and each slice reveals a tender interior with just enough structure to hold its shape.
The olive oil keeps it incredibly moist for days, making it ideal for special occasions or satisfying cravings.
For presentation, dust with powdered sugar or add fresh berries—though the cake stands beautifully on its own. The recipe yields a 9-inch cake that serves 8-10, with options to adjust for cupcakes or sheet pan versions. Let's get baking!
Ingredients for almond flour olive oil cake
High-quality almond flour and olive oil create a tender, vegan cake with bright citrus notes.
| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 2 ½ cups | Finely ground, unsweetened |
| Extra-Virgin Olive Oil 🫒 | 1 cup | High quality, fruity variety |
| Granulated Sugar 🍚 | 1 cup | Organic preferred |
| Ground Flaxseed 🌾 | ¼ cup | For flax eggs |
| Unsweetened Almond Milk 🥛 | 1 cup | Vanilla or plain |
| Lemon Zest 🍋 | 2 tbsp | Fresh, organic lemons |
| Orange Zest 🍊 | 1 tbsp | Fresh, organic oranges |
| Lemon Juice 🍋 | ¼ cup | Freshly squeezed |
| Baking Powder 🍞 | 1 tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
The almond flour is the foundation—Bob's Red Mill or Anthony's Goods brands yield the best texture. Look for finely ground flour with no added oils or sugars. The olive oil should be extra-virgin (not light or refined)—California-based brands like Corto or Colavita deliver that fruity depth. Citrus zest needs to be fresh; organic lemons and oranges from the produce section work best. If you can't find organic, conventional is fine—just wash the zest thoroughly. The flaxseed should be ground fresh if possible, but pre-ground works in a pinch.
No almond milk? Oat milk or coconut milk both work well, though the flavor will differ slightly. Short on zest? Double the juice for brightness. The baking powder must be aluminum-free—Bob's Red Mill or King Arthur are reliable. For a richer flavor, add 1 tsp orange extract alongside the vanilla. If you're baking at high altitude, increase the baking powder to 1.5 tsp. The powdered sugar can be swapped for confectioners' sugar if needed, but it won't be as fine.
This cake keeps beautifully—3-4 days at room temperature in an airtight container, or 1 week refrigerated. For longer storage, slice and freeze portions for up to 3 months. The olive oil helps maintain moisture, so it won't dry out like many gluten-free cakes. To reheat, wrap slices in damp paper towels and microwave for 10-15 seconds. The citrus notes intensify slightly after 24 hours, making it even more flavorful the next day.

- Leftovers That Last: This cake stays fresh for days, if it lasts that long. Between us, I’ve had it for breakfast, packed it in lunches, and even reheated slices in the toaster for a quick snack. The flaxseed keeps it dense enough to hold up, no sad crumbs here.
Step-by-step instructions for almond flour and olive oil cake
Here's how to achieve a tender, citrus-infused cake with perfect moisture every time.
Prepare the Flax Eggs and Combine Wet Ingredients
In a small bowl, whisk together the 0.25 cup Ground Flaxseed with 0.25 cup Lemon Juice. Let it sit for 5 minutes while you prepare the rest—this creates a gel-like substitute for eggs that binds the cake. The mixture should thicken noticeably, resembling raw egg whites.
In a separate large bowl, combine the 1 cup Extra-Virgin Olive Oil with the 1 cup Granulated Sugar and 1 tsp Vanilla Extract. Whisk vigorously for 2 minutes until the mixture lightens in color and becomes slightly thickened. This step incorporates air, which helps create the cake's signature tender crumb. I like to use a hand mixer for this part—it's more efficient than whisking by hand.
Mix Dry Ingredients and Combine with Wet
In a medium bowl, sift together the 2.5 cups Almond Flour, 1 tsp Baking Powder, and 0.5 tsp Salt. This ensures even distribution of leavening and prevents dense pockets in the cake. Gently fold the dry mixture into the wet ingredients using a spatula, mixing just until combined—overmixing develops gluten and can make the cake tough.
Add the 2 tbsp Lemon Zest and 1 tbsp Orange Zest, along with the flax egg mixture you prepared earlier. The citrus zest will infuse the cake with bright, aromatic flavor while keeping it moist. Mix gently until everything is incorporated, but avoid creating air bubbles. The batter should be thick but pourable, similar to cookie dough.
Fold in Almond Milk and Prepare the Pan
Pour the 1 cup Unsweetened Almond Milk into the batter and gently fold it in using a spatula. The milk adds moisture and helps create a fine crumb. Be careful not to overmix—just combine until the liquid is evenly distributed. The batter will be quite thick, which is normal for almond flour cakes.
Preheat your oven to 350°F and grease an 8-inch round cake pan thoroughly with olive oil. Line the bottom with parchment paper for easy removal. The olive oil ensures the cake won't stick, while the parchment prevents any potential burning on the bottom. Tap the pan gently on the counter to remove any air bubbles that might have formed in the batter.
Bake Until Golden and Springy
Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. Almond flour cakes can sometimes look underdone on the outside while being fully cooked inside, so rely on the toothpick test rather than just the color.
During the last 5 minutes of baking, cover the cake loosely with aluminum foil if the top begins to brown too quickly. This prevents over-browning while still allowing the cake to cook through. The cake should spring back slightly when pressed gently in the center—this is your sign that it's perfectly baked.
Cool and Dust with Powdered Sugar
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This gradual cooling prevents the cake from cracking as it sets. While it cools, prepare the 0.25 cup Powdered Sugar for dusting—this adds a delicate sweetness and makes the cake look beautiful.
Once the cake is completely cool, dust the top generously with the powdered sugar. I like to use a fine-mesh sieve for an even coating. The citrus notes will shine through, balanced by the subtle sweetness of the almond flour and olive oil. Serve slices at room temperature for the best texture and flavor—this cake keeps well for up to 3 days stored in an airtight container.
Pro Tips For Making Almond Flour Olive Oil Cake
- Whisk the Flaxseed: DESCRIPTION: Let the ground flaxseed sit with almond milk for at least 10 minutes before mixing—it thickens into a gel that binds the cake better than rushing it. I used to just toss it in, and the texture always felt a little loose.
- Measure Almond Flour Right: DESCRIPTION: Spoon the almond flour into the measuring cup and level it off with a knife—don’t scoop directly from the bag. Packing it down makes the cake dense, and you’ll end up with a brick instead of a tender crumb.
- Don’t Overmix the Batter: DESCRIPTION: Stir just until the dry ingredients disappear—overmixing adds air, and almond flour cakes tend to crack or sink in the middle. Fold in the wet ingredients like you’re being gentle with a fragile omelet.
- Bake at 325°F (Not Hotter): DESCRIPTION: Almond flour burns easily, so a lower oven temp (325°F) gives it time to set evenly without turning to charcoal. I learned this after one batch looked edible but tasted like a campfire.
Creative variations of this almond flour olive oil cake
Citrus Variations
Swap the lemon and orange zest for 1 tbsp lime zest + 1 tbsp grapefruit zest for a tropical twist. The grapefruit adds a tart complexity that pairs beautifully with the almond's nuttiness.
For a berry variation, replace citrus zest with 2 tbsp raspberry puree and 1 tbsp blackberry puree—this adds natural sweetness and vibrant color. 🍋
Spiced Olive Oil
Infuse your olive oil with warmth by adding 1 tsp cinnamon + ½ tsp cardamom to the oil before mixing with sugar. Let it steep for 10 minutes while prepping other ingredients. This creates a cozy, aromatic cake perfect for fall.
For a winter spice version, use ½ tsp nutmeg + ½ tsp clove instead. The spices dissolve completely into the oil, creating subtle depth throughout.
Nutty Additions
Fold in ½ cup chopped walnuts or pecans during the final mixing stage for texture contrast. Toast the nuts in a dry pan for 3-4 minutes until fragrant before adding.
For a chocolate twist, replace ¼ cup almond flour with ¼ cup cocoa powder and add 2 tbsp extra olive oil to maintain moisture. The chocolate version works beautifully with a dusting of cocoa powder instead of powdered sugar. 🌰
Flavor Boosters
Enhance the citrus flavor by adding 1 tsp orange extract alongside the vanilla. For a floral note, stir in 1 tsp rose water (available at Middle Eastern markets) during mixing. Both additions are subtle but elevate the cake's complexity.
If you love coffee, add 1 tsp instant espresso powder to the dry ingredients—it enhances the citrus notes while adding a sophisticated depth. 💫
Texture Variations
Create a gluten-free cupcake version by dividing the batter into 12 greased muffin tins. Bake at 350°F for 18-20 minutes until springy. For a sheet pan cake, spread the batter evenly in a 9x13-inch pan and bake for 25-30 minutes.
The sheet pan version is perfect for feeding crowds and can be cut into squares. For extra moisture, brush the baked cake with 1 tbsp simple syrup while still warm.

Frequently asked questions
Why does this almond flour cake need flax eggs?
Flax eggs replace traditional eggs by binding the moist almond flour and creating structure. The gel-like texture mimics egg whites, preventing a crumbly result. For best results, let the flax mixture sit for 5 minutes to fully thicken before mixing. This simple swap keeps the cake vegan while maintaining a tender crumb.
Can I substitute olive oil with another fat?
While olive oil adds fruity depth, you can use vegetable oil or melted coconut oil in a pinch. For richer flavor, try avocado oil. Avoid butter or margarine—they can make the cake dense. The key is using 1 cup total of fat for proper moisture.
How do I prevent the cake from cracking?
Cracking often happens from rapid cooling. Let the cake cool in the pan for 10 minutes before transferring to a rack. Avoid opening the oven door too soon—temperature fluctuations cause stress. For extra insurance, bake at 325°F instead of 350°F if your kitchen runs hot.
Is this cake gluten-free?
Yes! This recipe is naturally gluten-free since it uses only almond flour. Just ensure your baking powder and salt are certified gluten-free. The texture remains tender because olive oil and citrus prevent dryness common in many gluten-free baked goods.
Can I make this cake ahead of time?
This cake actually improves overnight. Store it in an airtight container for 3-4 days at room temperature. For longer storage, slice and freeze portions for up to 3 months. The olive oil keeps it moist even after reheating.
