Quick, easy and delicious Mint Aero Rocky Road. A no-bake chocolate traybake with biscuits, marshmallows and so much mint aero

Mint aero
I utterly adore Mint Aero… Like, if someone gave me the bag, I would happily finish it within minutes (and thats being slow). My no-bake mint aero cheesecake recipe that I posted recently made me realise that you all utterly adore the delicious treat too! Therefore, another Mint Aero related recipe simply HAD to happen. Hello, Mint Aero Rocky Road.
There is something about the mint aero that is just the level above any other mint chocolate bake I seem to know of – I adore how much lighter the chocolate is, and I think it mixes in so well with other bakes.


Mint aero rocky road
I wasn’t entirely sure what to name this as I use the same chocolate mix as my Rocky Road recipes with the chocolate, butter, and syrup and this is purely because I much prefer the taste of it compared to using just melted chocolate.
I’ve finally remade this recipe after nearly two years of forgetting to have put marshmallows in the first time, so thats all that is different in this updated version! Honestly this recipe is such a crowd pleaser whether it has marshmallows in or not, so its down to you if you include them! Luckily, its easily adaptable.
- Milk chocolate – I use milk chocolate as the base of this recipe as I adore it, but you can easily switch to dark chocolate
- Butter – it’s important to use block butter and not a baking spread to prevent the mixture splitting
- Golden syrup – the holy grail of my rocky roads
- Mint Aero – I use the bubbles, but you can use the bar


No-Bake
I decided to make this treat on the hottest day of the year so far which might have been a mistake, but it was so quick and easy to make it didn’t really matter.
It still set perfectly fine after being in the fridge over night and it still tasted perfect. I do recommend (as noted in the method) to leave the chocolate mixture to cool slightly, especially if you have melted it over a double boiler which I prefer using anyway.
This is to prevent the mint aero bubbles from completely melting into the mix, as I like seeing them and having the chunks of them throughout! I did add in some digestives to this treat as well, as I like having the crunch and something slightly less sweet, but you can easily use any biscuit you please.
I decided to drizzle mine in a mint colouring white chocolate drizzle as I wanted it to actually look minty, and this allowed me to stick extra Aero bits to the top. I honestly utterly adore this simple yet delicious no-bake treat, and I know you all will too.


Tips & Tricks
- If you don’t like mint, you can 100% use the normal aero bubbles, or swap it to a chocolate treat of your choice. However, I couldn’t love mint aero anymore than I already do, so this is already one of my favourite recipes.
- I really would recommend using just milk or dark chocolate for the base of this recipe as it melts better than white chocolate. The white chocolate might mix/split when mixing it with the golden syrup or butter, which I have had happen to me several times!
- I use this milk chocolate in this recipe
- I use this 9″ square tin
- I use this green food colouring
- If your mixture splits, it’s probably over heated or been over mixed – take it off the heat, and whisk in some whole milk to bring it back
- You can easily half the recipe for less, but these are so moreish you will want the large piece
- This recipe will last in the fridge for 7+ days, IF it happens to last that long!
- You can freeze this rocky road for 3+ months

Instructions
- Line a 9×9″ square tin with parchment paper and leave to the side.
- In a large bowl, add in the chocolate, golden syrup, and butter
- Melt on a low heat over a double boiler, or in the microwave on low, in short bursts until fully melted
- Alternatively, add the syrup and butter to a pan and melt. Add in the chocolate (off heat) and stir until combined and the chocolate is melted.
- Once its melted and combined wait 5 minutes for the chocolate mix to cool a little.
- Add in the chopped biscuits, mini marshmallows, and Aero Bubbles and quickly fold together – pour into the tin and spread so its even and refrigerate until set.
- Melt the white chocolate on short bursts in a microwave, or over a double boiler until melted.
- Add in a bit of green food colouring to get a ‘minty’ colour and drizzle it all over the traybake.
- Sprinkle on the crushed mint aero pieces so they stick and refrigerate again until set.
- Chop up the pieces into either 4×4 for 16 larger pieces, or 5×5 for 25 smaller pieces. Enjoy!

Hi Jane! Lovely recipe! I wanted to know what else we can use instead of golden syrup for this recipe ?
Hiya, aw thank you!! For the base of this recipe golden syrup is essential x
This was amazing to make and it tasted so good. I made 2 batches, one for my second family. And the other for home. However it has been split between home, and 3 different works. I highly recommend this, and so does everyone that tasted it!!
Made this back in October, it tastes and looked amazing. It didnt last very long in our house. Love your recipes, what shall I make next 🤔
Made this a few times now and honestly my fave tray bake/Rocky road EVER!!
So tasty!
Was amazing made for school project
These were delicious – didn’t last long when I made them the 1st time last week, so making them again today.
Very more-ish.
I love trying out your recipes, I always have great feedback when trying them out on my victims 🙂
Hi Jane,
How many grams on mint aero bubbles did you use? Thank you xx
300g mint aero used in the recipe as mentioned, and then any extra you want to decorate the top!
How long do you have to leave it in the fridge for it to be completely done?:)
I would say a couple of hours, but sometimes it can set quicker for others xx
Hello,
What food colour did you use? I’ve found green superflair on Amazon but not sure which green as there’s loads? Spring Green, Pastel Green, Holly Green lol 🤦🏻♀️
Thank you
Emily
I find the holly green makes a good mint colour, but I’m sure any will work! Or you can use any other brand such as progel, or colour splash is also good! x
I can’t find green food colouring anywhere can I add green icing to the white chocolate instead??? Thank you ☺️
Hey! No I don’t think that would work very well – it’s best to just leave it off or keep it white! And as a side note buying food colouring online is better as shop bought stuff sucks! X
It would of been a goof recipe but like others I added good colouring to white chocolate just clumps together so kind of spoilt it.
Unfortunately that can happen with poor quality colours (supermarket ones) – I have linked on the post to the one I recommend!
I tried this recipe for the first time this evening. Had exactly the same thing happen despite using supermarket own brand chocolate and 100g dark chocolate as I’d read in the comments. I stirred it so quickly and for so long I thought there must be something possible to do to sort it out, I just added about 2-3tbsp boiling water and mixed with a wooden spoon quite literally as quickly and powerfully as possible and managed to resurrect it to get a nice shiny smooth chocolately mix! Give it a go next time it definitely worked for me. Apart from that little mishap which I’m chuffed I didn’t have to waste all that chocolate and golden syrup, this might well be my new favourite recipe. Best of luck x
This was LOVELY! A very easy recipe to follow, I will be making this again.
Thank you so much!! This is one of my favourites!!
Made this delicious recipe so many times as it’s always requested now when I visit friends. It’s easy to follow and works perfect every time. Thank you Jane for sharing this amazing recipe. x
Awh amazing! Thank you!! x
