Keto Vanilla Cake

My Keto Vanilla Cake is a very special recipe! It is basically a keto yellow cake (made with whole eggs) and flavoured with vanilla. I was determined to create a cake that would become a firm favourite with everyone. It took a while to get it right, but it was so worth it. The best bit is this cake can be made and changed to almost any flavour you can imagine.

This recipe was originally published back in 2018 but has had a recent update. The recipe has not changed at all, just a few tasty new pictures.

This vanilla cake is low-carb and, being sugar-free, is perfect for a keto or diabetic-friendly diet. It has the most amazing texture, as it is both dense as well as light and fluffy. You will definitely not get anything this good from a boxed vanilla cake! It is also the perfect sugar free birthday cake!

The Ingredients

Jump to the recipe card for the full list of ingredients to make this low carb keto vanilla birthday cake recipe.

Keto Vanilla Cake ingredients all labelled on old tiles.

Light taste olive oil – use an oil with a neutral flavour. Oils like extra virgin olive oil are too strong for the cake. You can use butter or ghee.

Sweetener  – I use monk fruit/erythritol or erythritol. These are the products I use Sukrin:1 or Monkfruit sweetener.

Almond flour or almond meal – Almond meal and almond flour are slightly different in consistency, with almond meal being a bit coarser. You can choose either for this recipe.

Eggs – I prefer to buy fresh, free-range, jumbo eggs whenever possible and have them at room temperature before using them in a recipe.

Sour cream or Greek yoghurt. – Coconut cream can be used for a dairy free keto vanilla cake.

Baking powder – I use and recommend Bob’s Red Mill Baking Powder for all low carb gluten-free baking. It really helps give a good rise and consistent baking results every time.

Step 4. MIX buttercream ingredients in a stand mixer until light and fluffy.

Step 5. FROST: Pipe thickly onto the edge of the bottom cake and spread it with an angled spatula. Place the second cake on top (if doing double) and pipe buttercream on top of cake. Using an angled icing spatula, generously spread buttercream over the sides and top of the cake. Scrape the frosting back for the naked cake look, or just keep it smooth and creamy.

Hot Tips & FAQs

Can I double or triple the mix?

For layered cakes, like mine pictured, it is safe to double or triple the recipe in both a stand mixer and the Thermomix®.

Can I use extra virgin olive oil instead of butter?

Extra virgin olive oil (EVOO) has a very strong flavour that will overpower the delicate vanilla flavour. If you want to substitute with olive oil, choose a light tasting olive oil instead.

Can I vanilla cake with coconut flour?

No, you can’t. The recipe would have to be completely different because coconut flour is very thirsty.

How long can this cake be stored?

You can store the keto vanilla cake, in an airtight container in the fridge, for up to 1 week. You can also freeze it for up to 1 month.

Ingredients 

KETO VANILLA CAKE

KETO VANILLA BUTTERCREAM

  • 1/2 cup (100 g) powdered sweetener
  • 2 teaspoons vanilla extract
  • 4 tablespoons butter cubed
  • 250 g (9 oz) cream cheese softened, and cubed
  • 1/4 cup (60 g) sour cream

Instructions

CONVENTIONAL METHOD

  • PREHEAT – to 160℃ fan/180°C static/350°F. Line a 20 cm (8-inch) springform pan.
  • MIX all ingredients in a stand mixer until combined. Spoon mix into prepared pan.
  • BAKE 30 minutes or until cooked through. Cool on wire tray until cool.
  • MIX buttercream ingredients in a stand mixer until light and fluffy.
  • FROST: Evenly cover the top of one cake (if doing double) with half of the frosting. Top with second cake and spoon the remaining frosting onto the top. Use an angled spatula to smooth over top. Chill for 1-2 hours before slicing the cake.
    For a “naked” look, gently scrape back icing using a cake scraper. Be careful to scrape icing back to edge of cake, and not to remove crumb. Garnish with fresh berries.

THERMAL METHOD

  • PREHEAT oven to 160℃ fan/180°C static/350°F. Line a 20 cm (8-inch) springform pan.
  • MIX: Place all ingredients into mixer; Mix 1 min/speed 3. Follow from Step 3 above.
  • FROST: For frosting; mix all ingredients 1 min/speed 5. Scrape down sides of bowl. Repeat until smooth and fluffy. Follow instructions above for frosting the cake.

Notes

  • My pictures show 2 cakes, and I doubled the recipe to make two full size. You can use one batch and slice the cake in half or use smaller pans to make layered easy keto cakes, if you prefer.
  • For the top layer Strawberry Frosting; I added one tablespoon of strawberry juice (I pushed a berry through a sieve) to give a subtle flavor and color to the cream cheese frosting.
LOW CARB CAKE INGREDIENTS
Choose light tasting olive oil and do not use extra virgin olive oils as they have a strong flavour. Melted butter or ghee can be used in place of the oil.
Double acting baking powder reacts and creates gas bubbles twice; once when moisture is added, and a second time when it’s heated. In comparison to a regular baking powder, this gives keto and gluten-free baking a better texture as the ingredients are denser and need a bit more help with rising. 
I use blanched almond flour to make a prettier gluten free vanilla cake. You can use natural almond flour or almond meal in its place. You can use macadamia flour or cashew meal (higher carb) in place of the almond flour. Coconut flour is not a suitable substitute. Coconut flour sucks up a lot of moisture and more ingredients would need to be added to compensate in this almond flour cake.
Sweetener: I use monk fruit sweetener or erythritol sweetener in my keto cake recipes. I find they give the cake a good texture without having a cooling effect. 
It is always better to line all your baking tins, as this ensures that the cake can be removed easily.
It is really important to allow the cake to cool completely before icing it, otherwise, the buttercream will melt. Use sugar free sprinkles for an easy vanilla birthday cake. Or add colour and flavours to the buttercream frosting to make a fancy keto birthday cake. 
LOW CARB VANILLA CAKE IN THERMOMIX
For a keto layer cake like mine pictured, it is safe to double or triple the recipe in both a stand mixer and the Thermomix®. Just make sure to bake each cake separately not at the same time. 
STORAGE AND FREEZING KETO CAKES
You can store the vanilla keto cake in an airtight container in the fridge for up to 1 week. It freezes well if kept in an airtight container or ziplock bag. I freeze in individual portions so it is simple to defrost when I would like a piece of cake.
This recipe yields approximately 16-20 servings. The actual number of servings will depend on your preferred portion sizes. 
To calculate the weight of one serving, prepare the recipe as instructed. Weigh the finished recipe, then divide the weight of the finished recipe by 16-20. The result will be the weight of one serving. 
Nutritional values shown are guidelines only. They are for 1 serving using the ingredients listed. 
All recipes have been tested using all of the cooking methods included by various recipe testers.
Store in an airtight container in the fridge for up to 5 days. Alternatively, store in an airtight container and freeze.

      You could use a liquid coconut oil Nadine, preferably not one with a strong coconut flavour.

    Hi, is your nutritional info for the cake alone or with the butter cream?. I just put mine into my tracker and my counts are WAY above yours I have 330 calories and 12.5g carbs per slice. It was all well and good till I got to the frosting. Please help me work out what I’ve done wrong.

      Hi Cassie, they do include the buttercream. Check your sweetener. I use zero calorie zero carb Sukrin products.

    What a beautiful looking cake! Love the use of almond meal, I totally get how it makes a dense but light cake when combined with a high quantity of eggs. I bet this is just as delicious as it looks 🙂

    HI Megan – thanks for the recipe. Looks great. If making chocolate would you add cacao powder or cocoa powder but reduce almond meal by the same amount or doesn’t it matter?

    Reply
    1. Megan

      I would just add 1 tbsp of unsweetened cacao. No reduction of almond meal is needed.

    I can’t wait to try this as a coffee cake. Megan how much coffee powder would you recommend for the cake and butter cream?

    Reply
    1. Megan

      Hi Leisa,
      I would use around 1 tbsp (dissolved in 1tbsp water) in both the cake and buttercream. Alternatively a ristretto shot of coffee and just add as needed.
