Chocolate Orange Tray Bake

Deliciously rich chocolate cake smothered in silky buttercream and flavoured with orange. This Chocolate Orange Tray Bake is a simple cake to whip up for any occasion. 

Who doesn’t like Chocolate Orange?

I know there will obviously be a few people out there that aren’t fans, but chocolate orange is such a well loved and popular flavour combination. I’ve already got recipes for Gluten Free & Vegan Chocolate Orange Cupcakes, Chocolate Orange Rocky Road & Chocolate Orange Cookie Bars. So you can tell I am definitely a fan! But I wanted a cake that was absolutely delicious but simple too.  

Not a new concept, but a tasty one! 

I think most bloggers that bake will have a chocolate orange cake recipe. Like I said it is a well known, delicious combination and we all have our go-to recipes. What makes this Chocolate Orange Tray Bake my favourite is just how rich and flavoursome it is. I have really packed in the orange flavour which I think is essential. If something is meant to be orange flavoured then it really needs to taste like orange!

I have also made sure that the buttercream is rich and delicious. Personally, I am very fussy when it comes to buttercream and would usually choose a different frosting – like my Chocolate Cream Cheese Frosting. But I do like chocolate buttercream when it is rich and creamy. To make this even more creamy, I have used whole milk. You can go the extra mile and use cream, or you could be slightly more reserved and use semi skimmed milk. Whichever you choose will still be delicious but will slightly change the creaminess. 

Quick, easy and delicious 

Aside from the deliciousness of this cake, the other thing I love about it is how quick and easy it is to make. Tray bakes are great because you don’t have to worry about dividing the cake batter into multiple tins or spooning it into cupcake cases. You just tip the whole lot into your prepared tin and you’re ready to go. 

It also makes decorating even easier! Instead of messing around with piping bags all you need to do is pile the buttercream on and spread it out – easy! I do like decorating cupcakes and making pretty patterns with my buttercream. However, there are occasions when you don’t have time; Christmas being one of them! This Chocolate Orange Tray Bake is ideal because it requires minimal effort but still looks and tastes great. 

Get creative with your decorating

When I decorated this Chocolate Orange Tray Bake I went for a quite reserved colour scheme. I was trying to be classy with my gold sprinkles and chocolate orange segments. If I was making this for my friends and family (and not to be photographed on my blog!), I would might have added some Christmas sprinkles to make it more festive. Obviously this cake can be made all year so use whichever sprinkles take your fancy. 

For the chocolate orange segments I used the other half of the chocolate orange that hadn’t gone in the cake batter. If you want every slice of cake to have an orange segment on it to avoid arguments (amongst children or adults!) you might want to buy a packet of the smaller segments. 

Uses for orange juice 

This Chocolate Orange Tray Bake uses quite a bit of orange zest. When you’ve zested an orange it tends to become hard and unappealing in a day or two. If you don’t want to just juice the orange and drink it like I did, here is some inspiration below of delicious ways to use it.

    Oh this looks so yummy. And you are so right, at this time of year you don’t want to be fussing around with fancy decorations. Thanks for adding my orange curd recipe – I’m going to try out your recipe and see how it turns out with orange curd icing
