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

  • 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.

    Your Mint Aero slice has been a firm favourite of mine at Christmas for years. I was talking to a friend about it and she asked for the recipe. I found it again online to send to her (I have it printed out from YEARS ago) Noticed you re-did it since the original – to include the marshmallows, not sure why you’d ruin it like that! lol guess that’s just my personal preference. (I add sultanas to mine and call it tiffin – no marshmallows)

    Made this for Mother’s Day afternoon tea and it was a big hit. I halved the recipe and used a smaller tin which worked out perfectly. Decided to omit the green food colouring for decorating as was worried it would clump the chocolate as others had mentioned but it still looked great sprinkled with remaining Aero. Will make again for sure.

    I made this with dark chocolate and substituted Mint Matchmakers (broken into thirds) for half the Aero Bubbles. I also used chopped Mint Club biscuits as I forgot to buy digestives! It was super- indulgent, but everyone loved it. Thanks, Jane 🙌

    Hi Jane. I love all your recipes. I have made several different rocky roads, and they have all turned out perfectly. However, my last 2 attempts having quite gone to plan. When mixing the chocolate into the butter and golden syrup, all the liquid separates from the chocolate. What am I doing wrong?

    • Jane's Patisserie on July 18, 2023 at 2:01 pm

      Hiya! This is likely either the mixture becoming too hot and splitting, or its the chocolate brand you are using. I use supermarket own basic chocolate and it works wonders – you can also try adding some whole milk/cream and beating like crazy to bring it back x

      I’ve just tried to do the white chocolate drizzle with white choc and the green food dye and it seems to have solidified as I’ve mixed the food dye in! Any idea where I’ve gone wrong?



    • Jane's Patisserie on August 21, 2024 at 9:23 am

      What food colouring did you use? If it was water based and one from a supermarket this will have seized the chocolate x

    Made these for my mum and she LOVED them. One tip: make sure the milk chocolate being used when making this recipe is one that melts well!

    • Sarag on May 16, 2024 at 8:02 am

      Just wondering could you make these without the marshmallows and what qould I substitute? Thanks.
