Chocolate Sheet Cake with Fudge Pieces

This simple chocolate fudge traybake is super tasty and ridiculously easy! It’s rich, moist and gooey with plenty of delicious chocolate fudge flavour!

Easy & Simple Chocolate Fudge Cake Traybake

In fact, this recipe is so good that instead of frosting or icing it just has gooey melted fudge – what could possibly be better than that? Plus, it’s a traybake which means that the cake mixture is light and cakey with a gorgeous not-too-rich chocolate flavour. Who doesn’t love a good traybake?

You can eat so many things as a traybake – from simnel cake to sticky chicken, traybakes really can do it all! And why shouldn’t they? There are so many advantages!

For one, there’s minimal washing up (of course) which everyone loves – there’s nothing worse than a meal eaten while dreading having to sort out the mess that is currently your kitchen!

Also, they’re specifically designed to be easy! Just look at this one-pot halloumi bake – you essentially just dump in everything except the halloumi and bake, then add the halloumi and carry on! And even the most obsessive chefs love a meal like that every once in a while – especially if it tastes as good as this chocolate fudge traybake! After all, everyone loves chocolate and fudge!

This chocolate fudge cake is particularly perfect for sending into school on your children’s birthdays – kids just adore it! Especially if you decorate it with copious amounts of sprinkles and far more candles than any child should ever need.

Plus, lots of people don’t love icing or frosting. Some find it too sickly sweet, while others dislike the texture. The melted fudge pieces on top really shine in these scenarios as they end up with a light crust on top where they’ve solidified, but when you get in through that thin, crackly layer they just ooze out – and everyone loves some good oozy fudge!

Of course, if you’re a real baker, you could make the fudge yourself by using our traditional Caribbean Rum Fudge Recipe. Feel free to omit the rum for the non-alcoholic version!

Why should I make this chocolate fudge traybake?

What do I need to make this simple chocolate fudge cake?

You don’t need much, and certainly nothing rare here! The only thing you might have trouble finding are the fudge pieces. 

You just need:

  • Unsalted butter, ideally at room temperature, but it doesn’t matter too much because you’re melting it anyway.
  • Light muscovado sugar. If you can’t find this then light brown sugar is the best substitute for both flavour and texture.
  • Double cream. Sadly, in this case, single cream just won’t cut it. You need the richness and creaminess here to bring the right texture to the chocolate fudge cake.
  • Cocoa powder. We use regular cocoa powder here instead of Dutch-process cocoa powder because the two are actually surprisingly different.
  • 2 eggs. Ideally at room temperature, as per usual. We used medium eggs so make sure that you do too in order to get the best possible texture.
  • Self-raising flour – this helps to form the structure of the cake, as well as to let it rise and form those lovely little air bubbles!
  • Fudge pieces – Don’t have any? Use our Rum Fudge Recipe to make a quick batch! Feel free to substitute according to the info below, though!

If you want a more rich, chocolatey cake: add an extra 5g of cocoa powder.

INGREDIENT ALTERNATIVES 

Can I use a different egg size for this traybake cake?

If you don’t have medium eggs, see this post for charts on how to convert between the different egg sizes. It’s a very useful chart to have on hand!

Can I use a different flour?

If you don’t have self-raising flour, feel free to use regular plain flour, but make sure you follow the instructions here to ensure that your traybake rises just the right amount!

What if I can’t find any fudge or don’t want to use it?

You’ll find fudge pieces are usually next to chocolate chips and chunks in the baking aisle, but if you really can’t find them then you can always use larger fudge squares or even toffee. Salted caramel also works wonderfully here as the salt also brings out the flavour of the chocolate cake!
