What is a traybake?
In Australia, this delcious no bake dessert is called Maltesers slice. A British classic, it’s known in the UK as Malteser traybake. Sometimes baked and often not, a traybake is a flat dessert that is cut into squares then served. It’s sometimes referred to as a Malteser tiffin too.
Ingredients and substitutions
Just 7 simple ingredients makes this Maltesers slice recipe fantastically easy.
Detailed quantities and instructions in the recipe card below.
- Maltesers: Of course, you need Maltesers for a Malteaser traybake. Maltesers are crunchy chocolate coated malt flavoured candy. In the US, Whoppers would be your alternative.
- Malt biscuits (cookies): You’ll need a good crunchy biscuit / cookie that’s preferably malt flavoured, though plain flavours will work too. I use Arnotts Malt o Milks. Digestive biscuits, rich tea biscuits or graham crackers would work too.
- Cocoa powder: You only need a touch of cocoa and could technically leave it out, but it does intensify the chocolate flavour.
- Golden syrup: Golden syrup is a thick, amber coloured sugar cane syrup. It has a unique but very light flavour and works perfectly here. It’s available across the world these days, but if you can’t find it, I would suggest rice malt syrup to be the best substitution. Honey would work but would give a very distinct honey flavour. You could probably get away with malt extract syrup too which would play into the Malteser flavour well.
- Chocolate: While I most often use dark chocolate in my baking and for eating, this is a fun, sweet nostalgic treat and works best with milk. You could use a combination of half milk, half dark if you’d like it less sweet.
How to make Malteser slice
This is oh-my-goodness-kinda-simple and the hardest part is waiting for it to set.
Detailed instructions in the recipe card below.
1. The melted chocolate mixture
In a medium saucepan over low heat, you’ll melt together chocolate, butter, golden syrup, cocoa and salt.
Important Tip! Low heat is very important here for the chocolate. If you overheat chocolate, it may seize and/or become dull. For this reason, make sure to heat the chocolate and butter mixture over low heat and stir almost constantly until the chocolate has just melted.
2. Combining it all
Once it’s smooth, pour the chocolate mixture over the biscuit crumbs and Maltesers and stir it all together with a stiff spatula or wooden spoon.
3. Assemble and chill
Tip the chocolate Malteser mixture into a baking tin that’s lined with baking paper and press it out level all over. Don’t worry if it looks a little greasy on top, it just means a little butter has separated but it will set up fine.
Add melted chocolate and more Maltesers to the top then place in the fridge for 4-6 hours or overnight to set. Make sure it’s wrapped well in plastic wrap.
Cutting: Once the Malteser traybake is set, you can cut it into small squares and serve. I find it best to leave it out of the fridge for 45 minutes to make it a little easier to cut through. It will crumble in places – that’s normal.
Storage
Malteser tray bake will store well for up to a week in the fridge. Make sure it’s either wrapped well in plastic wrap or in an airtight container. The Maltesers on top will soften over time and, if exposed to air, the malty centre can melt.
Can you freeze Malteaser traybake? It can be frozen though the texture of the Maltesers will change on thawing so it’s best eaten fresh.

Maltesers are a British, crunchy malt flavoured, crispy candy that’s coated in chocolate. They’re sold in many other countries as well, including Australia where they’ve been around all my life. In the US, the substitute would be Whoppers.
Golden syrup is an inverted syrup made from sugar cane. It’s a thick syrup similar in colour to maple syrup and has a caramelly flavour. While it’s readily available in a number of countries including the UK and Australia, in some places it may be tricky to find. I recommend ordering online if you can or you could substitute with rice malt syrup.
If you really want to use dark chocolate, I’d mix it half and half with the milk chocolate. Maybe top it with dark chocolate. This would cut down on the sweetness but it will still be rich.
