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 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.
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.
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.
I hope you enjoyed my 36-year-old diabetic birthday cake recipe. Happy birthday to you if you try this recipe for your birthday today.
