This Almond Flour Vanilla Keto Cake is the most delicious, moist, and buttery diabetic-friendly birthday cake. Plus, this vanilla keto cake is dairy-free, gluten-free, and made with only 6 ingredients in 1 bowl!

So keep reading to learn how to make the ultimate low-carb cake.

Here we are! It is my birthday, and I am turning 36. I am also celebrating 6 years of a happy sugar-free life and the reversal of my prediabetes. So it’s with a lot of excitement that I am sharing my easy keto birthday cake recipe with you today.

What’s a Keto Vanilla Cake?

This keto sponge cake is a simple but super tasty sugar-free vanilla cake that is also gluten-free and diabetes-friendly.

Because it is made with low-carb flour and no all-purpose flour, it comes with very few carbs: only 3 g of net carbs per slice!

If you follow the keto diet, this won’t hurt your macros, and you will stay in ketosis!

Sugar-free vanilla cake ingredients

Let’s see what you need to make this moist and buttery sugar-free vanilla cake.

  • Almond flour – I recommend fine almond flour for this Almond Flour Vanilla Cake rather than almond meal. Almond meal would work as well, but the cake would be less moist. Find other recipes with almond flour.
  • Eggs – this recipe is not vegan friendly. For a vegan cake, try my keto vegan mug brownie.
  • Sugar-free crystal sweetener – I love Monk fruit, but erythritol or xylitol are great options as well. Check out my review of keto-friendly sweeteners for alternatives.
  • Coconut oil – or any oil with a light taste will work very well here. Avoid vegetable oils. They are not keto. Good options are avocado oil, almond oil, flaxseed oil. If you are using melted coconut oil, make sure it is not burning hot when you add it to the cake batter. Hot oil will cook the eggs.
  • Baking powder or half the amount of baking soda, meaning 1/2 teaspoon.
  • Vanilla extract. Find all my recipes with vanilla extract.

Does Almond Flour have carbs?

Yes, Almond Flour does contain some carbs but far less than all-purpose flour. It gives about the same texture to baked goods as regular flour though.

What can I use instead of Almond Flour?

If you don’t have almond flour or are allergic to almonds, you can use Sesame Seed flour. It’s also keto-friendly and bakes similarly.

You can also use all-purpose flour but it wouldn’t be keto-friendly.

Can I use stevia instead of erythritol?

You can’t use pure stevia extract as Erythritol provides both sweetness and texture to this recipe. You need something that brings a sugar-like texture. A stevia and erythritol blend works. Allulose would also work.

Can I use coconut flour instead of almond flour?

No, this vanilla cake wouldn’t work with coconut flour instead of almond flour as coconut flour is 4 times more water-absorbent. It would make the cake very dry and gritty and would alter the flavor.

How to prevent the almond flour cake from sticking to the pan?

Usually, keto cake batter made with almond flour sticks a bit more to cake pans, so it is crucial to use a non-stick high-quality, aluminized pan.

It may sound expensive to invest in a high-quality pan, but they last for years. The one below is in my kitchen for 7 years, and none of my cakes stick to it.

Pan choice

I am using a 9-inch cake pan with a non-stick coating, removable sides that clamp around the base, and ridged texture at the bottom.

Making the Almond Flour Cake

Pan preparation

If your pan doesn’t have a ridged texture, your cake may stick slightly at the bottom. To prevent your keto cakes from sticking to the pan, I recommend a double-greasing method.

First, grease the whole pan, bottom, and sides with butter or coconut oil. Then, cut out a piece of parchment paper, the same diameter as the pan, so here a 9-inch circle.

Place the piece of parchment paper at the bottom of the pan. It will stick to the pan since you grease it before. Finally, grease the whole pan again, including the paper.

This 2-step greasing method will ensure that your keto cake does not stick to the pan.

Do I have to make a layered cake?

Of course, no! You can follow the keto vanilla cake recipe and serve this delicious almond flour cake in 30 minutes.

It is a good sugar-free vanilla cake to enjoy plain or with the vanilla buttercream frosting recipe provided.

I recommend making the layers and frosting, though, to have a lovely light and fluffy keto birthday cake.

How to make a beautiful layered diabetic vanilla cake?

To make the layers of this diabetic cake, I recommend baking 2 small vanilla cakes instead of slicing a bigger one. It means you repeat the entire low-carb cake recipe 2 times.

This is the best way to create a lovely keto sponge cake with even layers and a decent cake height.

Following are my top 3 tips to make a layer cake:

Tip 1: Make the vanilla cake recipe provided two times

I know it is tempting to double up the recipe to save time and then divide the batter in half. It would work, but I’m not too fond of this technique because it is challenging to halve the batter perfectly. Often, you end up with a layer thicker than the other.

Tip 2: Bake one almond flour cake at a time

Never bake two cakes at the same time in your oven. It will impact the baking time too much, and the baking would not be consistent.

There is always one cake that burns and one that is not cooked. So take the time and bake them separately.

Tip 3: Level the cake layers before frosting

Your sugar-free birthday cake will come up with a small bump on top. Fully cool the cake, then use a knife or a cake leveler tool to remove that bump and create 2 flat cake layers.

This will make it much easier to frost them later on.

How to assemble your keto vanilla cake?

First, make sure your low-carb cake layers are cool at room temperature to prevent the frosting from melting. Then, I recommend using a turning table and icing spatula.

Add a tablespoon of frosting to the center of the turning table and place the first cake layer on it. This frosting is not cream cheese frosting and so will act like glue and stick the cake to the table.

Next, add 1 cup of frosting in the middle of the cake. Spread the frosting with an icing spatula turning the table at the same time to spread evenly.

The frosting will fall on the sides, and that is ok. Finally, add the second cake layer and repeat this process until you have covered all the top of the cake. Use more frosting to cover the edges.

Ingredients

Vanilla Cake

Vanilla Buttercream frosting

Instructions

Vanilla cake

  • Preheat oven to 160°C (325°F). Grease a 9-inch round cake pan with coconut oil or butter. Cut out a piece of parchment paper into a 9-inch circle and stick it to the bottom of the pan. Grease the paper and pan sides again. These steps prevent the cake from stick to the pan. Set aside.
  • In a large mixing bowl, whisk eggs with sugar-free sweetener, oil, and vanilla. Process as if you whisked a breakfast omelet. It should not take more than 30 seconds to 1 minute, all you want is to combine the ingredients.
  • Whisk in almond flour and baking powder and whisk until evenly combined.
  • Pour the vanilla cake batter into the prepared pan.
  • Bake for 25 minutes in the center of your oven. The fan-bake mode is ideal if you have one. Otherwise, use the regular mode. Your cake is cooked when a skewer inserted in the middle of the cake comes out clean or with few to no crumbs on it.
  • Cool for 5 minutes in the pan, then release the cake on a cooling rack. Cool for 1 or 2 hours before adding the frosting, or enjoy plain.
  • Note that this is a gluten-free cake. It doesn't rise much. You should expect a small bump raise in the middle, not more. The recipe is made to create flat cake layers to make a layered birthday cake.

Layer vanilla cake

  • Repeat the vanilla cake recipe one more time to create a second vanilla cake.
  • Make sure you clean, dry, and grease again the cake pan before baking the second cake.

Light and Fluffy Buttercream frosting

  • Add the soft butter cubes and vanilla to a stand mixer. Make sure you use the paddle attachment. Mix on high speed until it forms a pale, smooth, and fluffy butter.
  • Reduce to low speed and gradually add the sugar-free powdered sweetener, half a cup at a time. When all the sugar-free sweetener has been added, mix on medium speed for 2 minutes until it forms a fluffy cream.
  • Add cream and keep whisking for 1 minute to incorporate.
  • Spread the frosting between the 2 cake layers and on sides using an icing spatula. Watch my video to learn how to frost your layer cake easily.
  • Place the cake in the fridge for 2 hours to set up the frosting if desired.

Storage

  • You can make this cake 24 hours before, store it in an airtight cake box in the fridge to prevent the frosting from drying.
  • Store leftover for up to 4 days in the fridge or freeze in ziplock bags. Defrost the day before at room temperature.
This recipe doesn't work with egg-replacer or flax egg, you must use eggs

  1. Can I use a combination of stevia and erythritol? I don’t have plain erythritol so would this work?
    Thank you:)

      • 5 stars
        Thanks! I went ahead and used the stevia and erythritol, same measurements as the recipe and it worked out just fine!! It was such a delicious cake!! Really moist, especially for a gluten free cake. If I didn`t know it was gluten free, dairy free, aaand sugar free, I would never have guessed! I didn`t make the icing, as I didn`t have powdered sweetener. Instead I used raspberry puree and it was very tasty!! Fabulous recipe, you`re a life-saver!

  2. 5 stars
    Very delicious cake. I add 2 TBS more oil as I thought it might turn dry. It was very moist and soft. Thank you for your always trustworthy recipes.

  3. 5 stars
    This was delicious!! Thank you! Have you ever tried making it with coconut flour? Do you think half almond, half coconut would work?
    Thanks x

  4. 5 stars
    Wow blown away how good this is , never had powdered sweetener so had with clotted cream , was sooo good

  5. Might be a dumb question, but are the ingredient amounts for both layers? Or should I double that when I gather the ingredients, and the recipe is just calling for one layer?

    Thanks

  6. In making the vanilla bday cake icing, u say to use a stand mixer w paddle attachment. I only have a hand mixer w the beaters it came with. Will I have a problem w the icing coming out good? Also instead of the heavy cream, can I use half+half, as that’s what I have?

  7. 5 stars
    Great recipe! I just made it to ease a cake craving and it was fast and easy. I topped it with whipped cream sweetened with sugar free maple syrup. Yum! But it would also be good with lemon drizzle as suggested in one of the other reviews. Thank you for the recipe x

  8. Hello, could you please recommend a couple of substitutions for the heavy cream to be used in the frosting. ( i cant find it where I live). Thank you!

  9. 5 stars
