This three layer Keto Carrot Cake is a stunner of a low carb dessert. Frosted with the best sugar-free cream cheese frosting, this cake will wow your friends and family. And it’s remarkably easy to make!
I am absolutely over the moon about this keto carrot cake recipe. Simply and utterly obsessed with it and I want to make it over and over again.
Trust me, this is high praise coming from someone who bakes a lot of keto desserts. And who typically leans hard toward the chocolate variety of anything. But I took one bite of this moist, tender keto carrot cake and I was instantly in love.
And it was high time that I posted something like this. I have many carrot cake flavoured recipes, like my popular keto carrot cake bars. But not a single one of them is a classic layer cake.
Many of you have asked for a classic Keto Carrot Cake and so I thank you for pushing me to this. Because it is beyond delicious!
Keto Cake Cookbook
Confession time! Part of the reason I chose to share this recipe now is that I am working on a new e-cookbook devoted entirely to keto cake recipes.
In case you hadn’t noticed, I love making low carb cakes that rival the conventional wheat-and-sugar variety. I derive so much pleasure out of creating something that no one guess is keto friendly.
I’ve got a classic keto birthday cake, of course, and a rich and delicious keto chocolate cake. But then I have more extravagant creations like Berry Chantilly Cake and Praline Sheet Cake.
I hope to have this book out by May or June, so keep your cake-loving eyes peeled!
Ingredients
For this recipe, I tried to stay true to the classic, with some notable keto substitutions.
The flours
Because carrot cake typically takes chopped pecans, I decided to use pecan flour as the base. It has great flavour and slightly fewer carbs than almond flour. I also added some coconut flour to help the overall consistency of the cake.
The sweeteners
Staying true to conventional carrot cake, I incorporated both a brown sugar replacement and granulated sweetener. Swerve Brown is, by far, the most like real brown sugar, and it deepens the flavor of the cake.
The spices
Carrot cake is really a kind of spice cake, so don’t skimp on the spices. I used plenty of cinnamon and some ground cloves. You can also add in nutmeg and a bit of ginger. But don’t overdo the ginger as it can overpower the rest of the flavors.
The carrots
As most of us are aware, carrots are not the most keto friendly vegetable. But you don’t have to add a lot to the recipe to give it the right taste and texture. Conventional carrot cake usually takes 3 cups of grated carrot. I cut this back to 1 1/2 cups and it was perfect.
How to make keto carrot cake
Making a keto carrot cake is really quite similar to the conventional version. Here are my best tips for getting it right.
- Prep your pans properly: This means both greasing them and lining them with parchment paper. Don’t skip this step!
- Finely grate the carrot: Choose the smallest holes on your box grater or food processor grating blade. This ensures better distribution of the carrot throughout the cake.
- Whisk the dry ingredients: Make sure to break up any lumps in the flours before proceeding.
- Beat the wet ingredients together, then add the dry ingredients all at once and beat to combine.
- Bake the cake layers: Be sure to divide the batter into the pans as evenly as possible. If you have a kitchen scale, that can help!
- Let cool completely: You know I always stress this, as keto cakes are very fragile when they are still warm.
How to make the best keto cream cheese frosting
Classic carrot cake takes cream cheese frosting and this one is no different! A few tips for a truly creamy, smooth frosting:
- Properly soften the cream cheese and butter: Make sure that they are soft enough to beat very easily. If you live in a cooler climate, as I do, room temperature may not be sufficient. I always give mine a few seconds in the microwave before I beat them together.
- Add the sweetener after they are smooth: Don’t try to beat it in right away, as it can cause some clumping. Wait until the cream cheese and butter mixture is nice and smooth first.
- Use room temperature cream: Adding cold cream can also cause the frosting to clump up, so make sure to let the cream sit out for 20 to 30 minutes.
- Crumb coat the cake: For this keto carrot cake recipe, I went with the more naked look. I simply spread enough frosting on the sides of the cake to coat it lightly. It was plenty of frosting in the end, as the cake is wonderfully moist.
Frequently Asked Questions
While carrots aren’t the most keto friendly vegetable, they are fine used in a recipe that serves 12 to 16. I found I could use up to 1 1/2 cups without raising the carb count much.
I haven’t tried making this recipe without nut meals as yet. But you could try replacing the pecan flour with sunflower seed flour. You will need to add 2 tablespoons of lemon juice to offset the green reaction.
Then simply leave out the added nuts in the cake and the garnish.
The cake will probably turn out with other sweeteners but I do warn you that allulose causes baked goods to darken very quickly and look almost burnt. For the frosting, you need a good confectioner’s style (powdered) sweetener.
Protein powder is a critical ingredient as it helps baked goods rise and hold their shape properly. You will find that my keto cake recipes are lighter and fluffier than many others. You can skip it, but please understand that your cake will be more dense and more fragile.
You can use whey protein, egg white protein, or some plant-based proteins. But don’t use collagen protein as it will make the cake gummy and hard to cook through.
You can make 1 1/4 to 1 1/2 times the frosting recipe to make a fully frosted cake.
Storage Information
Store the keto carrot cake in the fridge, with any cut edges covered with plastic wrap. I like it best served at room temperature so I recommend cutting slices when it’s cold and letting them sit out for a few minutes. The cake should last for up to a week in the fridge.
You can also freeze this cake, tightly wrapped up, for up to 2 months.

Instructions
Cake
- Preheat the oven to 350ºF and grease 3 8-inch round cake pans. Line the bottoms with parchment paper and grease the paper.
- In a medium bowl, whisk together the pecan flour, coconut flour, protein powder, baking powder, cinnamon, salt, and cloves.
- In a large bowl, beat the eggs and oil with the sweeteners until well combined and the sweeteners are mostly dissolved. Beat in the carrots and vanilla extract.
- Add the dry ingredients and beat on low until combined. Stir in the chopped pecans.
- Divide the batter evenly among the baking pans and spread to the edges. Bake 18 to 25 minutes, or until golden brown and the tops are firm to the touch.
- Remove and let cool completely in the pans, then run a sharp knife around the inside of the pans and flip out onto a wire rack.
Cream Cheese Frosting
- In a large bowl, beat the cream cheese and butter together until very smooth. Beat in the sweetener and vanilla extract until well combined.
- Slowly beat in the heavy whipping cream until a spreadable consistency is achieved.
To assemble
- Place one layer of cake on a cake stand or plate. Spread the top with one quarter of the frosting. Repeat with the remaining layers.
- Use the final quarter of frosting to lightly crumb coat the sides, so that the cake peeks through.
- Sprinkle the chopped pecans and shredded carrot around the outside of the top of the cake. Refrigerate 1 hour before cutting and serving.

This cake was absolutely delightful, perfect for a spring birthday! I just did it in two layers and omitted the heavy whipping cream from the frosting as it seemed easily spreadable without.
Thank you!
This made 3 very thin cakes – about an inch high? I experimented first as I’m making it for a friend’s birthday. I think I’ll make 50% more when I do it on the day to make bigger cakes. How would I adjust the cooking time? 25mins? I also lowered the oven temp to about 165C as they seemed to be browning quickly
What size pan did you use?
20 cm/8in
Could I make this with the King Arthur Keto flour? If so, what should I omit besides the nut flour? The protein powder? Thank you
I am sorry, I didn’t make my cake that way so you will need to experiment.
FANTASTIC!! I truly have not made a recipe from Carolyn’s site that isn’t delicious, but I generally prefer chocolate. :). I made this for Easter Sunday 2026. Substitutions: all almond flour, no pecan flour since I didn’t have any; I used Swerve brown sugar and allulose powdered for the white sugar. I used 9-inch pans that were dark colored and non-stick, so I decreased the baking time to about 12 minutes instead of 18. The frosting is a little tricky. I tried to rush the ingredients to room temp by microwaving but I wasn’t cautious and the first batch had lumps of butter and cream cheese. The second batch was much better- I did use close to 12 oz of cream cheese. I made sure it was creamy but not melted. I did the same with the butter and then creamed them for a good 2-4 minutes. Then I added vanilla and powdered allulose. It really didn’t seem like it needed additional liquid, but I still added about 1/4 c of warmed heavy whipping cream. It definitely did not need a full 1/2 cup. I mixed it for a good 3-4 minutes to ensure it was fully mixed. It spread on the whole cake with a little extra to make rosettes on the top. The cake was moist and the frosting top notch. Guests requested me to make it again for an event this summer. Thank you, Carolyn!
Hi. Can I use coconut oil instead of avocado oil, even though coconut oil is not liquid unless it is hot?
If not, is there any other oil you can recommend using?
Yes, it’s fine. Melt it first… it should be melted but not hot.
What adjustments should be made if I make this in a sheet pan or a 13×9 cake pan?
I haven’t done that myself, so just spread the batter in the pan and keep a close eye on it in the oven. Use tactile cues for doneness… the top should be just firm to the touch but don’t let it bake any longer once it is.
Can I make this as a sheet cake instead of a layered cake?
Sounds like you need to do some experimenting.
I don’t have pans to bake three so what can I use and what time and temperature to use
Can this recipe be made into cupcakes, by any chance?
Sure, but I can’t advise as to timing since I didn’t make mine that way. 🙂
I don’t get it, I followed the instructions except for using Lakanto sweeteners and it was super paste-like when I put it in the baking tins. It did not raise at all. Please help me fix this. Thanks.
Sounds like you didn’t have enough liquid. What brand of almond flour did you use?
Oooh, this was so great!! I made a birthday cake for a friend and for for myself, a tiny little mini cake on top of it! I also wanted to enjoy it! I received reviews even from non-keto friends.
I combined almond flour and pecan flour together, half-and-half. Absolutely wonderful with a cup of coffee!!
Love this recipe. It’s a go to anytime I need a dessert.
