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.

  • Preheat oven to 160℃. Line 3 x 20 cm springform tin.

  • Bake 30-40 minutes or until cooked through. Cool on wire tray until cool. Store in an airtight container in fridge for up to 1 week or freeze for up to 1 month


  • Mix all ingredients except crushed pecans in stand mixer until light and fluffy.
  • Pipe thickly onto edge of bottom cake spread over cake and down side.
  • Place second cake on top and pipe thickly onto edge and spread over cake top and sides.
  • Add third cake (with bottom of the cake facing upwards). Pipe generously with the frosting.
  • Using an angled icing spatula generously spread buttercream over sides of cake and top of cake. Once completely covered if you want to achieve the “naked” look gently scrape back the icing using the angled spatula or cake scraper. Be careful to only take bake to the edge of the cake and not to remove the crumb of the cake.


  • Preheat oven to 160℃. Line a 20 cm springform tin.
  • Place all ingredients (except carrot and pecaninto mixing bowl. Mix 2 minutes/speed 5, you may need to use spatula through lid to help mix. Transfer to large mixing bowl and fold through carrot and pecans. Follow from Step 3 above.


  • Mix all ingredients 1 minute/speed 5. Scrape down sides of mixing bowl. Mix for further 1 minute/speed 5. Follow frosting steps above.



  1. For a simple one-layer cake just divide the recipe by 3. Alternatively, all the mixture can be made as one big cake and extend cooking time as needed.
  2. Cake can be stored in the fridge for up to 5 days.
  3. Cut and freeze into individual portions in an airtight container.
  4. Use the leftover buttercream on another cake, store in the fridge for up to 4-5 days or freeze up to 3 months.
  5. Swap the cinnamon in the cake batter for 2 tablespoons of Chai Spice Mix.
I use a 15ml tablespoon and 250ml cup for measures. You can use the calculator to convert ounces in a cup if needed. Please note that there is also a conversion from metric to US Customary button under the list of ingredients.

    This amount in my TM6 made a 24cm and a loaf tin with plenty of buttercream, I used walnuts as I didn’t have enough pecans. Wowza what a beautiful full carrot cake flavour! I am excited we got 2 cakes as this is a special recipe but for everyday enjoyment. Thanks again Megan you really are the best recipe creator. ❤❤

    If I could give you a six stars officially I would,but here there are 🌟🌟🌟🌟🌟🌟 This is truly THE BEST CARROT CAKE EVER! I have been baking it for a long while, but this recipe is the best 👌 👍 😍 I made it into cup cakes for my hubby for Fathers day and it was the smashing hit! I will post pic in our FB group. You are genius Megan! THANK YOU!!!

    1. Megan Mad Creations Hub

      Haha! So happy you are loving it Nina and thanks for sharing your tasty looking pictures too.

  3. Kimberly Marshall

    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.

    1. Megan Mad Creations Hub

      Hey Kimberly, the recipe would still work perfect with no other changes needed.

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

    1. Megan Mad Creations Hub

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

  5. Erika

    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

    1. Megan

      Hi Erika, around that 60g egg. Either way it will work as we all have different sized eggs.

    2. Mia

      Unbelievably delicious. Such a big cake and very worthy as a celebration cake.

      1. Megan

        Thanks Mia. I am pretty infatuated with this recipe lol

    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!

    1. Megan

      Thanks Shanika. In this kind of cake you can barely even notice the difference over normal flour.

    1. Megan

    This Keto carrot cake looks positively scrumptious! The fella follows a keto diet so I’m positive that if I let him know about this recipe he’d beg me to make it. Can’t wait to try this out for our next cake worthy event!

    Carrot cake has always been my favourite dessert. So much so that I request a carrot cake every year for my birthday! Love that it is refined sugar free, and I’ve also been cutting back on grains, so I appreciate that it is grain-free too!

    1. Megan

      Thanks Leanne for your review. Give it a try, you will never know the difference I promise.

  14. Carrot Cake has always been a family favorite at my house and you cake is just beautiful. My husband and son follow a low carb lifestyle so this delicious beauty will be making an appearance at my house soon. You have so many wonder ideas to make a yummy cake!!

      Thanks Debbie. I hope everyone loves the cake. Honestly I can’t even tell the difference from one with flour and sugar, except for the lack of insulin response and no weight gain 😝

    Carrot cake has always been a firm family favourite. My grandma used to make it for us on special occasions. This Keto carrot cake reminded of hers.
    This carrot cake is so much nicer than any of the non Keto recipes I have made in the past and the maple cinnamon buttercream is divine. This recipe made 3 layers . I did a double layer for my family and gave a single layer to my daughter in law as it’s her favourite cake too.
    It got the thumbs up from everyone and even the non keto family enjoyed it.
    This is a super moist delicious cake.
    Thanks Megan you have excelled with this one!!

    1. Megan

      Thanks so much for your great review Lynda. I am so glad the family enjoyed it
