A Keto Carrot Cake to rule them all! This is seriously one amazing cake!

For more years than I would like to count I made carrot cakes every day in a cafe in Newcastle.

I could never believe how popular they were! FYI I most certainly did not eat cake back in those days.

This low carb carrot cake is a little different than my cakes of old, but I am certain they are better! My almond flour carrot cake is grain free, gluten free, and sugar free.

Keto Carrot Cake

Some of you may hesitate at the carrot.

If it is a concern and you want to lower the carbs in this keto carrot cake, then you can leave it out with no other changes to the recipe.

It is your call. With all the other flavours used this cake will still be moist and delicious without it.

The Ingredients

  • Light tasting olive oil – or substitute ghee or melted butter
  • Sweetener – any granulated sweetener can be used. I use erythritol.
  • 12 large eggs – use large room temperature eggs so that the cake does not taste eggy.
  • Nut butter, I used Mayvers oven roasted peanut butter
  • Maple flavoured syrup – the sugar free variety

How to Make It

This really is an easy recipe. Basically you can whisk this altogether in a large bowl, use a stand mixer or a Thermomix®.

All my recipe temperatures are based on a fan-forced oven unless otherwise stated.

I always line my springform tins so the cake can easily be removed.

Allow to cool completely before attempting to ice with buttercream.

Frosting the Cake

You can frost the cake however you please with it just added thickly on top or a little bit fancier. I have gone for a very trendy keto naked cake look. There are just a few tips for frosting this way. 

If doing a layered keto naked cake look first start with cutting the top off your cakes to completely level each cake. The excess cake tops can be used for some very tasty Cake Bliss Ball recipes.

Once level pipe a thick circle of frosting around the edge of the cake and one in the middle. Using an angled cake spatula smooth out the layer between the cakes but leave the thick outer circle as is. 

Frosted Carrot Cake

Top with next layer and repeat. (If doing more than 2 layers keep repeating as needed).

Pipe remaining frosting on top of cake. Using angled spatula smooth over top and spread frosting over sides of cake. 

Once the sides are covered, gently scrape back with angled spatula or cake scraper until you unveil the outer edge of the cake with just a thin scraping of frosting.

Any excess frosting can be added to the top or used in another recipe.

See how to frost the cake below on video.

    I love making Carrot Cake, but never had the Keto version! However, the fact that it’s flourless makes it such a great contender to give it a try! I’m loving the use of Almond meal instead!

  • Erika says:

    I am definitely going to try this, as carrot cake is my favourite.
    Just one question. Eggs, when you say large egg, do you mean the 50g Australian large or the U.S. 59g large egg?
    Thank you for all your hard work

  • Sharna d'Fern says:

    Hi Megan,
    Adelaide here.
    Can you tell me where I can source maple flavoured syrup please? I would love to make your carrot cake.

    • Megan Mad Creations Hub says:

      Hi Sharna, Coles and Woolies do stock Queens Maple Flavoured syrup or you can order from Sukrin Australia online.

  • Kimberly Marshall says:

    No Keto police, please! Would it throw the recipe off if I threw in a few raisins? My husband loves raisins, and he is not Keto. So it would be a compromise.
