Chocolate Orange Loaf Cake is a super tasty treat. It’s moist, sweet and filled with gorgeous orange flavour. It’s also really easy, so perfect for baking with kids this Christmas.
Chocolate orange is one of those classic flavour combinations that always tastes amazing.
It’s also, largely thanks to the popularity of Terry’s Chocolate Orange as a stocking filler, something that we all associate with Christmas, despite not being remotely festive. See also mint chocolate and After Eight Loaf Cake.
This Easy Chocolate Orange Cake is so simple. I use my basic loaf cake recipe and add some orange juice and chocolate orange.
It’s absolutely one of my favourites, and because it’s so simple, this Chocolate and Orange Loaf Cake recipe is perfect for baking with the kids which is always a favourite rainy-day activity in our house.

Ingredients for Chocolate Orange Loaf Cake
As I say, I stick to my basic 170g sugar, butter and flour recipe. 170g is around the weight of 3 medium eggs. If your eggs are significantly bigger or smaller than standard, weigh them and adjust the other ingredients to match.
For my Terry’s Chocolate Orange Loaf Cake, I use:
- Terry’s Chocolate Orange. I put half in the cake mixture and keep half to decorate. Alternatively, you can just use milk or dark chocolate. You’ll still get the orange flavour. You can also, of course, use unbranded orange chocolate, most of the supermarkets do their own version of the segments in pouches or blocks.
- Margarine. I use margarine for most of my cakes. It’s cheaper, and we tend to have a big tub in the fridge. You can swap for butter if you prefer, just make sure it’s at room temp.
- Caster Sugar.
- Eggs. Medium will do.
- Large Orange. I use the juice and zest for more flavour.
- Self-Raising Flour.
- Cocoa Powder.
Can you Use Orange Extract in Chocolate Orange Cake?
Yes, you can use orange extract in this Choc Orange Loaf Cake.
I personally prefer to use the juice and zest of one large orange.
If you do use extract, you’ll only need a teaspoon, as it’s a more concentrated flavour. This will also mean that your Choc Orange Cake batter is thinner, so reduce the flour by 30g. It may also bake faster, so be sure to check after 40 minutes.
Ingredients for Chocolate Orange Buttercream
Chocolate Orange Icing is the perfect topping for a chocolate orange loaf cake. However, you can just make chocolate buttercream, or even orange buttercream if you prefer.
Again, this is just my basic buttercream recipe, with added bits to make Chocolate Orange Frosting. I use:
- Butter. For the cake, I use margarine. For the buttercream, I use butter, at room temperature. If you use margarine, which is oil-based, you’ll need a lot more icing sugar, and the flavour won’t be the same.
- Icing Sugar.
- Milk Chocolate. I basically use milk chocolate because then you can use half the chocolate orange in the cake and half on the top. If you want to use it in the buttercream too, you need another one.
- Orange Juice or Extract.
Can You Use Orange Extract in Chocolate Orange Buttercream?
Yes. Actually, I recommend it.
Fresh orange juice is great, perfect for the cake. But when it comes to buttercream the consistency is super important and really easy to get wrong.
A little too much liquid, and it won’t pipe well. Not enough and it’s too stiff. Chocolate Orange Buttercream with Orange Juice can be hard to get right.
If you like quite a mild orange flavour, then the juice of half an orange in your chocolate orange buttercream might be perfect. But I’d still add it a little at a time, stirring it in before adding more, to maintain a good consistency.
If you prefer a stronger orange flavour, a teaspoon of orange extract is a better choice. It’s a stronger flavour, but you are adding less liquid, so you don’t need to worry as much about a sloppy buttercream.
In the recipe below, I use orange extract. But feel free to use fresh orange juice if you prefer, just adding a bit at a time.
Making Chocolate Orange Loaf Cake
Decorating a Chocolate Orange Loaf Cake
I decorate my orange loaf cake by piping on the buttercream and adding some orange segments before sprinkling over some orange-coloured sprinkles.
You can absolutely just spread on the buttercream though, or even use the chocolate orange to make a ganache for the top.
How Long Will This Cake Last?
I store my chocolate orange loaf cake in a glass cake stand on my kitchen worktop, it stays fresh for around 3 days.
I know some people prefer to store a cake with buttercream in the fridge. But I’ve never had a problem. The sugar kills any bacteria and using butter instead of margarine means that it stays stiff.
However, if you feel safer storing it in the fridge, it won’t hurt and can be a good idea if your kitchen is particularly warm or if you don’t plan to eat it within 3 days.
