Carrot Cake!

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.

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.
