Malteser Traybake Cake!

Thick and fudgey Malteser traybake cake with a malt fudge sponge, malt buttercream frosting and Maltesers!
Traybake cake
It’s been a while since I shared a traybake cake recipe, and all in all, I’ve only ever posted a few on my blog… It’s definitely an underrated type of bake, and I need to rectify my lacking in recipes urgently.
The last traybake cake I shared was my chocolate cake traybake back in August, and even though it’s been a long old while since then, that cake is still SO popular these days!
The cake has been so popular because it’s essentially a traybake form of my chocolate fudge cake, and who doesn’t love a traybake cake for a party?!Think about those chocolate traybake cakes you can buy from the supermarket (which are epic), and then multiply the epic-ness by 100.
Malteser traybake cake
I’m not trying to blow my own trumpet here, but the cake really is epic and utterly DELICIOUS. However, I have had requests and requests for more traybake cakes, just like that one! So… here is the Malteser version.
Yeah, that’s right, the Malteser version. I am utterly head over heels in love with this beauty, and I can’t stop the love. It’s based on my Malteser cake, and then also the chocolate cake traybake. The morphing of the two, into heaven in a bite.
Malt everything!
The premise of the bake is essentially the exact same, but just better. I went for a Malt Chocolate sponge, and a Malt Buttercream Frosting because it just tastes sooo good along with the Malteser, and I can’t get enough.
Malt powder
Whenever in recipes I say “malt powder” I mean Horlicks or Ovaltine – I’m not sure what the equal to these are in other countries like America, but here they are a delicious warming drink that’s kinda like hot chocolate, but not chocolate. If you like Maltesers, I’d be surprised if you didn’t like malt drinks.. but you know, weird things can happen!
The one thing I wouldn’t recommend for the cake or buttercream though is the Malteser hot chocolate as that’s not the best for baking.I’ve tried using the Malteser hot chocolate in bakes a few times, but it’s structure and ingredients are just completely different, and it’s designed to be mixed with water rather than milk so can work out oddly. If you use an actual malt drink such as Horlicks or Ovaltine, you will get a much much better flavour!
Coffee
One thing I will say AGAIN with this fudgey type cake recipe is that the coffee is IMPORTANT. Don’t worry, you can NOT taste the coffee in the cake, but it just enhances the richness of the chocolate in the sponge and takes it to the next level.
Please, for the love of god, don’t take out the coffee. People I know aren’t the biggest coffee drinkers, and some even hate it, but they all say they can’t taste it in the recipe and it is delicious.
This recipe is wonderful, it is Malteser heaven, and I hope you all love it too! Enjoy! x
Malteser Traybake Cake!
Ingredients
Cake Ingredients
- 250 g dark chocolate
- 250 g unsalted butter
- 2 tsp coffee granules
- 125 g malt powder (Horlicks/Ovaltine)
- 200 g plain flour
- 35 g cocoa powder
- 1.5 tsp baking powder
- 1/2 tsp bicarbonate of soda
- 250 g golden caster sugar
- 250 g light brown sugar
- 4 medium eggs
- 100 ml buttermilk
Decoration Ingredients
- 200 g unsalted butter (room temp)
- 400 g icing sugar
- 75 g malt powder (Horlicks/Ovaltine)
- 2-4 tbsp boiling water
- 200 g Maltesers
Instructions
For the Cake!
- Preheat your oven to 160C/140C Fan and line a 9x13" tin with parchment paper.
- In a heatproof bowl, microwave the dark chocolate and butter until melted - I do mine in 30 second bursts!
- Add your coffee granules and malt powder to a small bowl, and add in 150ml boiling water. Whisk until smooth!
- Add this to your chocolate/butter mix and whisk again until smooth.
- In a large bowl, add your plain flour, cocoa powder, baking powder, bicarbonate of soda, golden caster sugar and light brown sugar and whisk until distributed evenly!
- Whisk the eggs and buttermilk together until smooth.
- Add your melted chocolate mix to the bowl, and your egg/buttermilk mix, and fold all the ingredients together till they are combined - I use my hand and a spatula, and not an electric mixer as I don't want the ingredients to over mix.
- Pour the mixture into the lined tin, and bake in the over for 50-60 minutes, or until baked through.
- Leave to cool in the tin for 10-15 minutes, and then on a wire rack fully!
For the Decoration!
- With an electric mixer, beat your butter on it's own for a few minutes so it's lovely and supple.
- Add in your icing sugar 1/2 at a time and beat for a few minutes!
- Add in your malt powder, and beat again - if its stiff, add in 1tbsp of boiling water at a time and beat fully each time till its a thick but spreadable and smooth consistency!
- Spread over the cake with an angled spatula, and then sprinkle over some Maltesers and some crushed Maltesers!
Notes
- This cake will last for 3-4 days+ at room temperature in a cake box!
- This Is The Cake Tin I Used
- If you don't want to use Malt Powder, up the coffee to 1tbsp, and lower the water to 125ml - and just leave it out of the frosting!
- The cake can take longer to bake in some ovens if they're not the correct temperature - or if the mixture is over mixed!
- You can make your own buttermilk by using the same quantity of WHOLE milk, and 2tbsp of Lemon Juice - but I prefer the actual buttermilk you can buy!
ENJOY!

Hi, can this made as a two layer round cake.? I’m thinking of using two 8 inch round pans?
This is such a lovely cake. I made it for the first time today and was horrified at the vast quantities of sugar however it’s a massive cake and the taste is delicious. The cake dipped in the centre (I checked it and it needed a couple more minutes longer in the oven) and it’s not the prettiest but it tastes fantastic. The cake itself is really light and fudgy and the edges are crunchy and delicious. I’ve not made any topping as it’s great without. I’ll definitely be making this recipe again. I think even Mary Berry and Paul Hollywood would be impressed.
Lush, because this is so good, I have just pre-ordered the cook book, one very happy bunny here
Fabulous, so love this recipe made it for church coffee
morning whilst the children are off school and it
disappeared like magic!
Love that you included the link to the right size pan
Thank you so much
Mine sunk in the middle too! Didn’t open the oven door before 55 minutes or overmix… seems most people are having the same problem 🤔
What chocolate did you use for the base mixture?
Can you advise why my cake sunk in the middle. It looked fabulous for the first 40 mins of baking and then started to sink. What did I do wrong?
Did you open the oven door? This nearly always means the oven door was opened too soon, or it was under baked x
Hii, would I be able to use a 12 x 9 size traybake tin for this recipe? Xx
Yes thats fine x
Hi can i use milk chocolate instead of dark chocolate and will it still taste ok with the coffee thanks x
Hiya! Sadly you definitely have to use dark chocolate with at least 70% dark chocolate for the bake to work! Hope this helps! x
Hi Jane! Just wondering how the baking time will differ if I halve the ingredients and bake it in a 8 x 8 tin? Love your recipes!xx
Yes half is good for an 8″ tin!! I’m not sure on baking times but it’ll be quite a bit less x
This is sooooo delicious! Mine sunk a little too but who cares when it tastes so great? Thank you so much for continuing to give us such lovely FREE recipes!
Hi Jane,
I made the Malteser traybake with my girls and it turned out pretty well. It did sink in the middle slightly but the cake was so lovely and rich because of the dark chocolate. If I made it again, I’d probably do less of the buttercream (just personal preference) but my youngest had a great time helping! I’ve given a third of it away to the neighbours and we still have a load left over!
Hi I’ve made this traybake before in the 9 x 13 inch tin you suggested. It turned out amazing, the best cake I’ve ever made/tasted! However I had to give a fair bit away to my neighbours as it was too much for 2 people!
I’m craving it again now but I want to make a smaller amount in an 8 x 8 tin. Should I use 2/3 of the recipe?
Thanks!
I would use half! x
Hi Jane, do you think halving the recipe to use 9” square tin would be ok? Or maybe 2/3? I don’t need such a big cake – just wondering if there was away to make it smaller? Thanks!
I would use 2/3 of the recipe! xx
Love the texture of this cake. Mine sunk in the middle as I had to check on it after 55 minutes (took 80 minutes at 140 degrees in my fan oven) but after icing/decorating you could hardly tell. I think the buttercream icing amounts could be reduced as the icing layer was quite thick but otherwise I will definitely try make this again!!
Read the comments and had the same issue as a lot of people. Took significantly longer to bake than 60mins and the cake came out as a dense brownie texture. Definitely wasn’t over mixed as just brought the ingredients together by hand. Still tastes good but not what I was hoping for
As mentioned it can take longer to bake – it is that sort of cake that can vary due to ovens! Also, it’s meant to have a denser texture as it’s a fudge cake type sponge, not a classic basic sponge, so sorry it wasn’t for you!
Hi Jane,
This looks amazing and planning on baking this next. Is it possible to freeze this once it’s baked and frosted?
Many thanks x
Hey!! Yes it can! x
Mine sunk in the middle before I had even opened the oven door. Could I have overmixed it? We used ordinary caster sugar as the supermarket did not have golden. Any tips?
That is usually because of over mixing yes – using white caster sugar vs golden won’t make a difference. x
