Everything You Need to Decorate the Perfect Traybake


Whether you’re just getting started with baking, or you’re a seasoned pro, a traybake is an excellent choice. Easy to make in one tin, with endless flavour options, it’s sure to be a hit. A simple sheet cake is a classic in itself – but it’s a great opportunity to get creative. Here we’re breaking down everything you need to decorate the perfect traybake!

So, bookmark this post, bakers! Making something that stands out from the crowd has never been easier.

All tools in this post are available from our shop – just click the links to explore!


For a bit of inspiration, we’re looking to this AMAZING zodiac themed sheet cake from our friends @jkbakes_!


Be honest – is frosting the cake your favourite part?! The perfect traybake deserves the perfect icing, and a delicious buttercream works a treat.

Piping on your frosting instantly transforms a sheet cake, adding flavour, texture and colour. And with ready to use buttercream available in just about any colour you could imagine, you might not even have to colour it yourself! Pick your favourite shade (or shades) and you’re good to go.

Icing Colourings


Can’t find the perfect shade pre-made? Never fear! It’s easier than ever before to create your own using our icing colourings.

Many of the colourings available are highly concentrated, so you only need a couple of drops to achieve your desired colour. Take your white icing, add a couple of drops of one or more colourings and mix. If the initial amount is more pastel than you’d like, add a little more until you achieve the right shade. There’s nothing more satisfying than piping a beautiful shade you mixed yourself onto the perfect traybake!

And why pick one colour when you could choose several?! We love this mix of purple, blue and cream on @jkbakes_’s zodiac cake!

From bold blues to pastel pinks and everything in between, shop our range of colourings here!

Piping Tools

Buttercream chosen, colours selected. Now it’s time to pipe! Whether you’re keeping things simple with one tool, or getting creative with several, we’ve got you covered.

Take a piping bag (one for each colour if you’re going for a mix!), add your piping nozzle and fill it with your buttercream. You can get extra creative here with tools like the Tri-Swirl coupler from Wilton. This allows you to pipe multiple colours at once!

The most important thing here is to play and have fun. Choose a mix of piping tips to create a range of shapes (like @jkbakes_ did here!). The perfect traybake is whatever you want it to be, so be brave and try different techniques!

We’ve said it before and we’ll say it again – what cake doesn’t benefit from some sprinkles?! And we’re not just talking 100s and 1000s (though they are a classic!). These days, the range of sprinkles available is endless, and choosing the right theme can be a lot of fun. With brands like Happy Sprinkles showing just how creative you can get with sprinkles, they aren’t just a finishing touch. They’re a key part of the perfect traybake!

If you’ve gone for a bold colour theme, like @jkbakes_ did here, a simple one colour mix can be an elegant way to add some texture and shine. Or, if you’ve gone for a more subtle frosting, go bold with a colourful themed blend!

Shop our amazing range of sprinkles now – you’ll be spoilt for choice!

A Cake Topper or Cake Charm


And finally, the pièce de résistance, it’s time to add a cute cake topper or cake charm. These are a really handy way to lean into a particular theme. They can also be a great way of adding some personalisation, which can elevate any sheet cake to the perfect traybake.

Here, @jkbakes_ used this cake charm to celebrate Libra season, perfect for a Libra baby! But the options here are endless! Whether it’s Mother’s Day, Christmas, Halloween or a big birthday, this one product is all you need to nod to the occasion.

Browse our Cake Toppers category to find the perfect fit for your next creation.
