Carrot Cake!
*This post may contain affiliate links. Please see my disclosure for more details!*
This classic carrot cake is an exceptionally moist, two-layer sponge made with oil instead of butter, packed with freshly grated carrots, vibrant orange zest, and warm spices. Prep takes 20 minutes, it bakes in 30 to 35 minutes, and it is topped with an ultra-fluffy vanilla buttercream.
Notes from The Patisserie
Unlike traditional sponges that rely on creamed butter, a spectacular carrot cake relies entirely on sunflower oil. Because oil remains a liquid at room temperature, it guarantees a crumb that is significantly softer, denser, and inherently more moisture-rich than a butter-based cake. It also means your cake will stay incredibly fresh and moist for days without drying out.
To elevate the sponge further, we add the finely grated zest of an entire orange. The natural citrus oils cut beautifully through the richness of the sunflower oil, brightening up the overall flavour profile and complementing the sweetness of the carrots.
Balancing the spice blend
The hallmark of a great carrot cake is its warmth. For this recipe, I use a specific trio of ground spices: mixed spice, cinnamon, and ground ginger.
- Cinnamon brings a familiar, comforting sweetness.
- Mixed Spice adds complexity with its notes of nutmeg, allspice, and cloves.
- Ground Ginger delivers a very subtle, sharp background kick that prevents the cake from tasting one-dimensional.
When mixing the dry ingredients into your wet carrot base, the golden rule is to avoid over mixing. Stir the batter until the flour is just incorporated, over working the gluten at this stage will turn your wonderfully soft, rustic cake into something tough and heavy.
Ingredients and swaps
Carrot cake is a highly customisable canvas, and you can easily adapt the textures to suit your personal preferences:
- Walnuts – I love walnuts in a carrot cake but these can be swapped for pecans or any other crunchy nut you fancy
- Sunflower oil – this is essential for creating the moist texture carrot cake is known for.
- Eggs – I use medium eggs
- Sugar – light brown sugar provides a rich caramel taste that runs through and complements the other spices
- Carrots – finely grated or you will end up with lumps of carrot baked throughout the cake rather that the sweet flavour
- Raisins – these are optional but add delightful, chewy pockets of concentrated sweetness throughout the sponge. You can swap them for chopped sultanas, dried cranberries, or omit them entirely.
- Orange zest – the sharp citrus helps to cut through the sweet cake, it makes such a difference
- Flour – I use a good quality self raising flour
- Bicarbonate of soda – this helps with the rise but also the texture of your sponge
- Mixed spice – a delicious addition to the cake as it adds depth of flavour throughout
- Ground ginger – a teaspoon is enough to taste the spicy kick
- Ground cinnamon – a teaspoon of cinnamon provides that sweet sharpness to your bake
Vanilla buttercream vs cream cheese frosting
I decorate mine with either cream cheese frosting or vanilla buttercream – as this one was made as a request from my friend, we went with the buttercream! The vanilla from the buttercream gives it a delightful sweetness that I think is a cakey marriage made in heaven!
Although you can obviously use cream cheese frosting, I like to switch it up now and again. The secret to making this buttercream exceptionally light and cloud-like is the addition of a small amount of boiling water at the very end of mixing. Whipping the buttercream on a high speed with that touch of hot water slightly softens the butter fats, yielding an incredibly silky texture that glides effortlessly onto the delicate sponges.
FAQs
You can use vegetable oil as a direct 1:1 swap. Any neutral-flavoured liquid oil works perfectly. Avoid using olive oil or extra virgin olive oil, as their strong, savoury flavours will overpower the delicate spices and orange zest.
This typically happens for two reasons: either the bicarbonate of soda was measured too generously (causing the cake to rise too rapidly and then collapse), or the oven door was opened before the internal structure of the sponge had fully set.
Yes, this batter adapts beautifully. For a rectangular traybake (9×13 inch), bake at the same temperature for roughly 25 to 30 minutes. For a loaf cake, it will need a deeper bake time of around 50 to 60 minutes.
Always use the fine side of your box grater for carrot cake. Finely grated carrots release the perfect amount of moisture and completely soften into the batter during baking. If you use a coarse grate, you will likely end up with crunchy, distinct orange strands in your finished cake, which ruins the silky texture of the crumb.

Storage and freezing
Because of the exceptional moisture content provided by the fresh carrots and sunflower oil, this cake keeps brilliantly and will stay wonderfully soft and flavourful for up to four days when kept covered at room temperature in an airtight cake tin or a dedicated cake box. It is best not to store this cake in the fridge, as the cold air can cause the sponge to dry out prematurely.
If you want to get ahead with your baking, the un-iced sponge layers can be wrapped tightly in a double layer of cling film and frozen for up to three months; simply defrost them fully at room temperature before assembling and decorating with your fresh vanilla buttercream.

I posted my recipe for my carrot & walnut cupcakes a while ago and they’ve been a massive hit – they’re a big reader favourite and an alternative to the classic carrot cake as they’re so light and flavoursome and yum yum yum.
If you prefer cream cheese frosting then you can always try my carrot loaf cake, it is DELICIOUS! I quite like that cream cheese frosting doesn’t necessarily go with every cake so when you do have it, it’s not boring and always tastes amazing.
Made this cake a few times now with one simple tweak which is amazing. Soaking the raisins in orange juice for 40 minutes while you measure out the ingredients then draining and adding to the mix is delicious. Thank you so much for this recipe, everyone I have made it for says it’s the best carrot cake they have ever had!
Hi Jane!
First thing to say; you are brilliant! All the bakes I’ve made from your recipes have been just wonderful!
Second thing; I’m sorry if you have answered this previously but how should I adjust the baking time if I only have one large round cake tin to bake it in?
Thanks for sharing your baking genius with us!!

Absolutely delicious. Such a lovely recipe. I did an orange cream cheese frosting due to preference. Will definitely be making this again 🥰
Hi, how long do I bake this for if I’m making a 10inch 3 tier cake? Thanks 🙂
What’s the measurements for a 3 tier cake? Many Thanks
Jane could you tell me how much buttercream I’d need for a 3 layer high one of these please? Covered on the outside and with the piping on the top?
Many thanks
I had to comment on this because I decided to enter our local pubs cakes and tarts competition at the weekend last minute and opted to do carrot cake, looked at lots of recipes and decided on this one.
I used the frosting recipe also instead of the buttercream and I only went and won the competition against a lot of affid bakers.
I got so many comments about this carrot cake and how good it was… I didn’t get to try it as everyone else ate it, but I made another today and honestly it’s the best Carrot cake I’ve ever had (and made).
Hi I would like to do a four layer version of this, what would the measurements cooking time and temp be?
Hi jane, could I make this into a four layer by using two 8 inch tins? If so what would the quantity be and the baking time/temp
If making a two layer 6 inch cake, I guess I’d use 2/3 of the recipe, but what about baking times/temp please?
The best carrot cake ever !! Easy to make and tastes amazing , everything that Jane bakes seems to taste amazing, the website and books are amazing
Thanks Jane, I love all your recipes that I have tried and they never go wrong.
This is by far the best carrot cake recipe that I have attempted and definitely a keeper!!
I didn’t use sunflower oil, I used extra virgin olive oil instead…despite worrying about the initial smell (kind of bitter) it came out wonderful!!
I also used cream cheese frosting instead of butter icing…it was delicious and my family loved it 🙂
What quantities of cream cheese and icing sugar did you use for your cream cheese frosting?
Thank you!
