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

Ingredients
- 400 g milk chocolate
- 125 g golden syrup

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! I love this recipe, I’ve made it twice. The first time everything went perfectly but the second time when I added the food colouring to the white chocolate the white chocolate clumped together making it impossible to drizzle. I used the same food colouring but different chocolate, could that have been the problem or was it something to do with the heat? Also what chocolate did you use? Thanks xx
What food colouring did you use? And what chocolate? Off the top of my head I can’t remember, but I believe it was probably Tesco supermarket own, but the food colouring was very strong so I needed little. However, if you really have to mix the colouring in, that can also cause a problem x
Made this twice this , once at Waitrose where I work ,and then again at home . Went down a treat in the dining room at work. And at home. Love all your recipes x
I used to work at a Waitrose till recently, so cool! And I’m so glad!! x
All your recipes are fab! Look forward to all your posts when you bake something new xx
Ooo yum I used to love aero bars as a kid, this looks so tasty as well!
What do u mean by a double boiler? Thanku
Its a heatproof bowl, above a pan of boiling water. Its worth a google.
If I half the recipe do I need to use a smaller tin to make it in?
I love this recipe, tastes so yummy. Are you able to freeze it?
I believe so!
This is so nice, thank you. Just wondering though – can you freeze it?
Hiya!
I only ever user the supermarkets own brand chocolate, I think you’ve just had bad luck. I’d have walked it all in together anyway! Tesco, Lidl, Asda chocolate all always work for me. x
What are digestives? When I hear digestives I think Tums or Enzymes. I am confused here. Thanks for your help.
Wow, just made this and it’s the BEST THING EVER!!! Can’t wait to try out more recipes from your site, thanks so much!
Absolutely delicious! I have… ahem… made it twice in the last week – to share, I should clarify, though I could happily have scoffed the whole lot myself!
This was absolutely scrumptious! Thank you! Couldnt wait for it to set completely to sample!
Yayyy!! x
Great idea….Photos look fab, followed the recipe but sadly the aero completely melted. Chocolate mixture was very runny and I put in less chocolate than recipe stated, so I added extra biscuits to soak up some of the runny-ness. Also cut up extra aero and pushed it into the top after I had put it into the tin. Lets hope it tastes ok when set! Thanks for the idea
Hiya – your chocolate mixture was far too hot then still if it melted the aero. You need to fold it through in as small amounts as possible to prevent melting entirely. If they did melt, that would be why the mixture was so runny. I’m sure it’ll still taste lovely!
Hi, I’m currently in the process of making this now! How long does it normally take for the base to set?
Can take a few hours to set fully in the fridge!
Yum! The photos look amazing <3
Thanks Lorraine! ☺️
Looks yummy!
Thank you!!
