Luscious Low-Carb Lemon Layer Cake

Good Wednesday to you, friends! I’ve been craving a lemony treat of late and a thrice layered citrus cake just seemed like the right way to go. The blueberry compote filling idea came last minute and I’m SO glad we didn’t skip it because it really takes this cake to the next level of satisfying deliciousness. It’s just messy in all the right ways– lemon blueberry goodness in each bite, with you guessed it, a sumptuous cream cheese frosting.

We decided to go with a more natural, decorative touch with this cake and it proved to be a lot of fun and pretty stress-free. It was lovely to forgo the piping bags and just adorn the cake simply with blueberries and mint. I’m not actually a natural cake decorator by any means, I’ve always loved baking, but this side of things has taken some time for me to develop. I used to work at TCBY in high school + early college and one of the duties was to decorate the frozen yogurt cakes. Mine were so bad they actually banned me from frosting them! 😉 I was demoted to the re-stocking of the topping bar and to the making of sundaes and shivers, haha. It was still great fun, it’s nice to work in a place that sells frozen treats because nearly everyone is delighted to see you. I definitely think I preferred serving yogurt to bartending, but that’s a story for another time…

What’s the best way to make this grain-free cake?

There are a few tips that I think will help ensure the best baking experience. First things first, you must cut parchment paper rounds to fit the bottoms of your cake pans. Greasing alone does not cut it with these lovely layers. It’s an extra step, but the easy release from the pan is so worth it! Second, we love to use these super thin Wilton Easy Layer Pans-we just used 3 of the pans for this recipe. Otherwise, you can just use 2 eight inch round cake pans for a two layer cake. Make note of the differing cooking times in the directions. And finally, read through the instructions prior to baking so everything goes nice and smooth. 🙂 (If you’ve made our low-carb red velvet cake, then this will be a cinch for you.)

Impossibly Delicious Low-Carb Lemon Layer Cake With Blueberry Compote

*4.9 net carbs per slice (including compote). Decorative blueberries will add some additional carbs.

*You can make your compote at the start to save time.



Cake Layers

  • 1+ 3/4 cups almond flour (Bob’s Red Mill)
  • 3/4 cup  Swerve Confectioner Sweetener (No substitutes)
  • 2 teaspoons baking powder (Hain brand is grain-free)
  • 1/2 teaspoon baking soda
  • 1.5 teaspoons gelatin
  • zest of 3 lemons
  • 2 eggs
  • 1/2 cup + 1.5 tbsp half and half  (or full fat coconut milk)
  • 3 tablespoons olive oil
  • 3 tablespoons fresh lemon juice
  • 1 tablespoon apple cider vinegar
  • 1 teaspoon lemon extract
  • 1/2 teaspoon vanilla extract

Blueberry Compote (Optional)

  • 11 oz fresh blueberries
  • 3 tablespoons water
  • Juice of 1 lemon
  • 3 tbsp Swerve Confectioner
  • 1 teaspoon gelatin

Cream Cheese Frosting (Dairy-Free Option)

  • 1 stick softened butter
  • 1 eight oz package softened cream cheese  
  • 1 tablespoon lemon juice
  • 1 teaspoon lemon extract
  • 1/2 teaspoon vanilla extract
  • 1 tablespoon half and half or coconut milk
  • zest of 1 lemon (optional)
  • 2 + 1/3 cups Swerve Confectioner
  • 1/4 teaspoon salt
  • blueberries and mint for decor (optional)


  1. Preheat oven to 350 degrees
  2. Grease cake pans and cut out a circle of parchment paper to line each pan– do not skip this step.
  3. In a large bowl, whisk together almond flour, Swerve, baking powder, baking soda and gelatin until very evenly combined. Add lemon zest and whisk again.
  4. Add eggs, milk, olive oil, lemon juice, apple cider vinegar, lemon extract and vanilla extract. Whisk rapidly until batter is smooth. Use batter immediately.
  5. Place layers into oven and bake at 350 degrees for 20-24 minutes. Carefully rotate the pans 180 degrees and lightly cover with foil at the halfway mark. At 20-24 minutes the layers will be ready to come out, they’ll still be a touch soft and golden brown at the edges. (The thin 3 layer pans only need 18 minutes cooking time).
  6. Let your layers cool COMPLETELY on the counter and once they are cool, run a knife around the edges and carefully flip them over onto a cooling rack or plates and let them rest for another 5-10 minutes before frosting. While you’re waiting for your cake layers to cool, go ahead and blend together your frosting. (*Tip–For an easy frosting experience, you can first freeze the layers. Then frost and stack each layer, finally frosting the top and sides.)
  7. For The Frosting: with a hand mixer, blend together the softened cream cheese and butter.
  8.   Chill the frosting in the freezer for 1o minutes for the butter to set up and whip again at high speed until smooth I like to then fold the frosting vigorously with a rubber spatula to further smooth it out.
  9. Make your blueberry compote: In a medium sized pot, add your blueberries, water, lemon juice and swerve. Sprinkle gelatin over top. Give it a good stir and bring it to a boil on medium heat, making sure to mix it every now and again. The juice from the blueberries will start to release. Turn the heat down a touch and let it lightly boil and simmer for a while, the liquid will start to reduce and thicken after about 7-10 minutes. Make sure to continue to stir so the compote doesn’t stick to the bottom of the pot. If you find it thickens too much, you can stir in a tablespoon or two of water. Make sure it is cooled before adding to the cake layers.
  10. Pipe or spread frosting onto the first cake layer and lightly spread your compote over the frosting and then top with the next cake layer and so on. Embellish the finished cake with blueberries and mint if desired. Serve and enjoy!!
  11. Store any leftovers in an airtight container and refrigerate, enjoy!


*Frosting tip: dipping your knife in warm water can help to spread the frosting more evenly and will also give you a smoother finish.

  1. Wow! This cake is so elegant! The layers look heavenly and I’m not sure why you were banned from decorating cakes because this is so professional. I’m looking forward to baking it 😀

    1. Thanks so much my friend! Oh and in my TCBY days, I was indeed a poor decorator, they were wise to keep me on sundae duty! 😉

    1. Hi, thank you for your comment! You could use a half teaspoon of agar powder in place of the gelatin, but this recipe requires eggs, so sadly I’m afraid it won’t be vegan.
