Grain-Free Lemon Rosemary Olive Oil Cake - refined sugar-free, dairy-free with a keto option. A perfectly sweet rustic cake recipe that's easy to make!

Many years ago, one of my girlfriends made an olive oil cake for her family’s Christmas dinner, which I attended.

She was gushing about it ahead of time and although she had made something like 6 other fancy dishes, she seemed to be the most excited about this cake.

I couldn’t for the life of me figure out what all the buzz was about.

Until I tried it.

All of a sudden, it became glaringly obvious why one would be so thrilled about a cake made with olive oil. 

In case you haven’t had it, olive oil cake is uniquely delicious! The olive oil serves as the fat in the cake, omitting the need for butter. 

While the flavor of olive oil isn’t overwhelming in the cake, it adds a subtle unique nuance and richness that makes it rustic and enticing.

If you’ve tried my Paleo Blueberry Cake, Grain-Free Cranberry Orange Breakfast Cake or Strawberry Breakfast Cake, you’re already familiar with the concept of using avocado oil or algae oil rather than butter.

Using that same concept, we’re just taking an olive oil approach and sprucing it up with lemon and rosemary flavors.

There are innumerable ways one can approach making a cake with olive oil, but I’ve chosen to take a zesty, herb infused approach by making it with lemon zest and dried rosemary. 

I use almond flour and pure maple syrup instead of regular flour and sugar, effectively making it grain-free, dairy-free, and refined sugar-free. 

Rich and sweet enough to enjoy as dessert yet savory and health-conscious enough to enjoy for breakfast or snack.

The texture is light, fluffy

Let’s get right into the details!

Lemon Rosemary Olive Oil Cake - grain-free, refined sugar-free, dairy-free, rustic and delicious. An easy, gluten-free cake recipe!

Ingredients for Rosemary Lemon Olive Oil Cake:

Eggs: Used to make the cake light and fluffy.

I haven’t tested the recipe using an egg replacement but in my experience, flax eggs should work (you’d need 3 tablespoons of ground flax seed and 9 tablespoons of water). Just note that the cake won’t fluff up – it will be dense, which I like, but keep that in mind if you’re looking for something fluffy. 

Extra Virgin Olive Oil: The star of the show! A simple ingredient that adds fat and flavor to anything it touches. The deep, rich olive flavor adds that rustic essence.

If you don’t keep extra virgin olive oil on hand, you can easily use regular olive oil – the olive flavor just won’t come through as heavily.

As a side note, if you prefer using avocado oil or coconut oil, either one work as a replacement.

Pure Maple Syrup: The sweetener! To keep the cake refined sugar-free, we use pure maple syrup

Vanilla Extract & Almond Extract: You can skip either or both of the extracts, but I feel they both add so much to the cake.

Almond Flour: Rather than using all-purpose flour, I like making the cake grain-free using almond flour. Almond flour is slightly grittier than regular flour, which gives the cake an added texture that enhances the rustic vibe even further. Almond flour also has a natural sweetness to it, lessening the need for excess sweetener. 

I use Bob’s Red Mill’s Finely Ground Almond Flour, but any brand of almond flour should work so long as it isn’t a coarse grind. Do note that some brands of almond flour absorb more liquid than others so if you use a different brand and the cake batter looks dry, simply add more olive oil until it resembles a thick batter.

Lemon Zest, Lemon Juice & Dried Rosemary: Flavor makers! The lemon zest and juice give the cake a bright citrusy zing and the dried rosemary gives it a unique depth of flavor that adds a touch of earthiness and makes the cake taste slightly savory.

Baking Soda & Sea Salt: We leaven the cake using baking soda. This ensures the cake bakes evenly and holds together nicely after slicing. Don’t skip it! The sea salt brings out the citrus, rosemary, and olive flavors and also enhances the sweetness.

Can You Taste The Olive Oil?:

You can taste the olive oil in an olive oil cake, especially if you use extra virgin olive oil. If you don’t like the flavor of olive oil, replace it with avocado oil, which has a completely neutral flavor. 

While it may sound like a strange flavor in a cake, the olive oil actually plays a supportive role in generating rich flavor and propping up that rustic vibe.

Let’s bake it!

How to Make Rosemary Lemon Olive Oil Cake:

Preheat the oven to 350 degrees F and line an 8-inch springform pan with parchment paper.

Add all of the ingredients for the cake to a blender and blend until completely smooth (note: you can perform this in a mixing bowl using a hand mixer if you prefer).

Add the ingredients for the cake to a blender and blend until smooth

Blend the cake batter ingredients in a blender

Transfer the cake batter to the lined cake pan and smooth it into an even layer.

Pour the cake batter into a cake pan

Bake for 35 to 45 minutes, or until the cake has set up and is golden-brown around the edges (mine takes 35).

Bake the cake until golden-brown

Allow the cake to cool for at least 20 minutes.

If desired, sprinkle the cake with powdered sugar and decorate with sliced lemons and fresh rosemary.

Slice and enjoy!

Olive oil isn’t considered to be paleo-friendly so this cake isn’t technically paleo. You can make it paleo by using avocado oil or coconut oil (if using coconut oil, be sure it’s melted).

Can I Make This Keto?:

If you’d like to turn this into a low-carb cake, you can replace the pure maple syrup with ½ cup of your favorite sugar-free sweetener. You’ll also need to offset the loss of liquid, so add an additional ¼ cup of olive oil or almond milk.

Questions and Reviews

  1. Would this grain free olive oil rosemary lemon cake need to be refrigerated? I was thinking about making one for a gift but would have to ship it and am not sure how well it might arrive.

    Thank you!

    1. Hi Nancy! It will last at room temperature for at least 5 days, though after that it may become stale. I haven’t tried shipping a cake before so I’m not sure how it will arrive either. If you do decide to do it, I would wrap it securely in plastic wrap, then place it in a zip lock bag to ensure the moisture stays in. Definitely be sure to note that it’s fragile! Let me know how it goes if you try it! xoxoxo

    1. Hi Marlene,

      Do you have an 8-inch or 9-inch square pan? If so, that would work better. A muffin pan would work too if you’re okay with making muffins (you’d bake at 350 for about 30 to 40 minutes for muffins). My concern with using a 10-inch is the cake will turn out pretty thin (more like the thickness of bars instead of cake). You could try multiplying the recipe by 1.5 and then you’d have enough batter for a 10 inch. Hope that helps! xoxo

  2. Thank you so much for this recipe. My Son has Crohn’s disease and is on the Special Carbohydrate diet and all the lemon cakes I’ve tried come out soggy. I did make a couple substitutions to meet the dietary guidelines but the cake turned out great, fluffy and very tasty. Thank you again.

    1. I’m so happy it worked out well for you and your son, Celia! My heart goes out to your family – I know Crohn’s can be a challenging disease. xoxoxo

  3. This cake was just superb! Added 1/2 tsp. of lemon extract to the recipe and that took it to a whole new level of lemon deliciousness. Your recommended amount of rosemary was perfect — just a hint without overpowering the cake. Thank you for this, Julia! Your recipes are always my favorite and this cake will be a new go-to for me! 🍋💛

    1. Yaaay, I’m happy you enjoy it, Dominique! I just love that subtle rosemary flavor with the citrus. Thank you for the sweet note!

    1. Hi Sara! I haven’t tried it yet but in my experience, baked goods made with almond flour become pretty dense and have a “raw” like consistency in the center. Nevertheless, let us know if you end up trying it and how it turns out 🙂

  4. I made this without the rosemary to appeal to to both kids and adults. Everyone loved it! I appreciate a simple recipe with superb results!

  5. I am on a dairy, gluten and refined sugar free diet and this cake is AMAZING! I have made many cakes and this is by far the best. I had prepared it for a super and everyone loved it. I blended it in a food processor. Thank you.
