Keto Birthday Cake Recipe

When it comes to birthdays, we have a few keto birthday desserts on rotation. Our favorites are keto brownies, keto chocolate cheesecake and now, this easy keto birthday cake

I’ve been meaning to make a keto friendly birthday cake for ages now. I keep putting it off, but with my birthday fast approaching, I wanted to do something special and have my cake, and making it keto too.

Growing up, my birthday cake was ALWAYS a vanilla cake or a white cake. I never really chose those fancy flavors and loved the simplicity of it. To keep the tradition alive, my keto cake HAD to be simple yellow vanilla cake.

Now, this keto cake may look incredibly fancy, but I promise you, it is SO easy to make.

No grains, no sugar, and no dairy whatsoever, but you’d never tell. I served this with all my non-keto friends and NO one knew it was low carb and sugar free. In fact, several of them have requested it for THEIR birthdays! 

The texture of this birthday cake is JUST like any vanilla cake out there- moist and fluffy, with a tender crumb. The taste is gorgeous- sweet with notes of vanilla throughout.

Ingredients for a Birthday Keto Cake

Here is what you will need for this easy keto birthday cake. Please avoid substituting any of the ingredients, unless specifically stated. For such a fancy looking birthday cake, you’ll love this simple and easy ingredient list.

Keto Birthday Cake Ingredients

  • Almond Flour– You must use blanched almond flour, otherwise the cake will be darker and denser. Blanched almond flour is often called superfine almond flour. 
  • Coconut Flour– Works with the almond flour to produce a super fluffy and moist cake. DO NOT omit this or substitute this for something else. 
  • Baking Powder– Leavens out the cake and helps it rise. 
  • Salt– Brings out the sweetness of the cake. 
  • Butter– I used vegan butter, to keep it dairy free. If you use vegan butter, try to use the stick variety (not spreadable) as it doesn’t have any added water or fillers on it.
  • Sugar Substitute– You can use either monk fruit sweetener or erythritol. I prefer using monk fruit as it is most similar to white sugar.
  • Eggs– Use room temperature eggs, not refrigerated. 
  • Milk of choice– Almond milk, coconut milk, cashew milk, etc. All will work. 
  • Vanilla extract– A MUST for any cake or baked food recipe. 

How to make a keto birthday cake

This ingredient amounts provided for this low carb birthday cake recipe is to make a layer cake. If you’d like to make a single cake, simply halve the ingredients! 

Start by greasing two 8-inch cake pans and set aside. Next, combine your dry ingredients into a large mixing bowl and mix until combined.

In a separate bowl or in a stand mixer, add your sugar substitute with butter. Beat together the two ingredients until creamy and fluffy. This usually takes around 8 minutes. Continue mixing while adding the eggs in, one at a time. Next, add the milk and vanilla extract and beat it into the batter. Finally, add in the dry mixture and beat all together until creamy.

Finally, you’ll transfer the keto vanilla cake batter evenly amongst the two cake pans. Bake the cakes for 22-25 minutes, or until a skewer comes out clean. Allow the cakes to cool completely, before frosting them and layering them up.

Birthday Keto Cake Frosting Ideas

Any vanilla or white frosting will work, or you can even go the chocolate route. Here are a few other ideas-

  • Cream cheese frosting– Use any cream cheese frosting of your choice. Be sure to use dairy free cream cheese to keep it vegan! 
  • Cashew cream cheese frosting– My go-to frosting. It’s a little more time consuming but it’s so creamy, thick and rich! 
  • Whipped coconut cream– Simple and delicious! 

Keto Birthday Cake Tips

  • Again, this makes a keto layer birthday cake. For a single cake, halve the ingredients.
  • I highly recommend using a stand mixer or hand mixer to beat the ingredients. I tried mixing by hand and while it does work, I find the former have the fluffier texture. 
  • For a keto Funfetti birthday cake, add some sugar free sprinkles into the batter and on the frosting. 
  • Your cake must be cooled completely before frosting. 
  • Do not overbake the cake, as the cake continues to bake while it cools.

Is this a diabetic cake? 

Please understand that I am not a medical professional. While I am knowledgable about diabetes and the diabetic way of eating (my father is diabetic), every person’s carbohydrate and sugar needs are different. 

To see if this cake is suitable for a diabetic diet and can be considered a diabetic cake, please seek appropriate advice. 

Can I make this without eggs? 

I tried this keto vanilla birthday cake without eggs, using an egg substitute. The texture was not super moist or fluffy, and quite dense. If you don’t mind that texture, then use a pre-formulated egg substitute (e.g. ener-g egg replacer). 

I haven’t tried this with flax eggs or chia eggs, so please let me know if you try it out- I’d love to hear how it works! 

Storing and Freezing Keto Birthday Cake 

  • To store: Leftover sugar free birthday cake should be stored in the refrigerator, to avoid any potential spoilage. Keep the cake covered in a sealable container. It will keep well for at least 5 days.
  • To freeze: If you don’t plan on eating the keto birthday cake within 5 days, freeze the leftovers! Place slices of the cake in a freezer friendly container, or in large portions. Birthday keto cake will keep well frozen for up to 6 months.

    1. Can you tell me know many serving in a whole cake. I plan on baking this for an American Independence Day Celebration. Slicing each layer in half and filling with blueberries and raspberries with whipped coconut cream.

    2. OK, cutie, I’ve printed off the recipe, but where do I find the Cashew Cream Cheese Frosting recipe?? I’ve searched all over your site and can’t find it!!!

    3. Hi there! I love your recipes and have tried many but I get stuck with ones using coconut flour. I have a severe allergy to coconut unfortunately. Any suggestions for a sub? Thank you for all your wonderful work!

    4. Looks fantastic! But i have a question… this nutrition facts are just for the cake? Or includes any type of frosting?
