Why you’ll love it

Malteser traybake is rich and so delicious. Filled with milk chocolate, malt biscuits (cookies) and loads of Maltesers this is a very simple treat to make.

  • Very easy to make – no fancy equipment
  • Just 10 minutes effort
  • Rich in chocolate and malty goodness
  • Big thick slices

This addictive and easy traybake is great for a bake sale, birthdays, afternoon tea and parties and because it’s rich, it goes a long way.

I make mine in an 8 inch / 20cm square baking tin which makes for thick slices almost 2 inches tall, but feel free to use a larger tin like a 9 inch or even a swiss roll tin too if you’d like it thinner.

What is a traybake?

What we would call a ‘slice’ in Australia or ‘bars’ in the US, is known as a traybake in the UK. Sometimes baked and often not, a traybake is a flat dessert that is cut into squares then served. This British classic, Malteser traybake is often referred to as a Malteser tiffin or Maltesers slice too.  

Ingredients you’ll need

Just 7 simple ingredients makes this Malteser traybake recipe fantastically easy.

Detailed quantities and instructions in the recipe card below.

  • Maltesers: 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: 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.
  • Butter: Use unsalted butter so you can control the salt content.
  • Chocolate: While I most often use dark chocolate in my baking and for eating, milk chocolate is the go-to here. 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.
  • Salt: You just need a touch of salt to balance out the sweetness.

How to make Malteser tray bake

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. Dry ingredients: Use a food processor or blender to blitz your biscuits / cookies to fine crumbs. Add them to a large mixing bowl with your Maltesers.
  2. Wet ingredients: In a medium saucepan over low heat, you’ll melt together everything else (photo 1) – chocolate, butter, golden syrup, cocoa and salt. Once it’s smooth, pour the chocolate mixture over the biscuit crumbs and Maltesers (photo 2) and stir it all together with a stiff spatula or wooden spoon.
  3. Tip into a tin: Tip the chocolate Malteser mixture into a baking tin that’s lined with baking paper and press it out level (photo 3) 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.  
  4. Top it: Add melted chocolate and more Maltesers to the top (photo 4) then place in the fridge for 4-6 hours or overnight to set. Make sure it’s wrapped well in plastic wrap.
  5. 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.

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.

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 Malteser traybake? It can be frozen though the texture of the Maltesers will change on thawing so it’s best eaten fresh.

FAQs

What are Maltesers?

Maltesers are a British, crunchy malt flavoured, cookie-like 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.

What is golden syrup?

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.

Can I use dark chocolate?

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.
