Quick, Easy, and Delicious Mint Aero Rocky Road. Chocolate Traybake Filling with Biscuits , Mini Marshmallows and Oodles of Mint Aero Goodness!

I utterly adore Mint Aero Bubbles. 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 Slice.

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 find it easier to eat as its not as solid, and it just tastes so delicious. As I already have my recipe for my Mint Slice on here, which is a mix of a Biscuit Base, a Peppermint Creme, and Chocolate.. I couldn’t call it that.

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.

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. My Chocolate mix was just quite soupy is all!

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!

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 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! Enjoy!

Category: Dessert
Type: Rocky Road
Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes
Servings: 16 Pieces
Author: Jane's Patisserie


  • 400 g Milk Chocolate
  • 125 g Golden Syrup
  • 125 g Unsalted Butter
  • 150 g Digestives
  • 150 g Mini Marshmallows
  • 300 g Mint Aero
  • 75 g White Chocolate
  • Green Food Colouring
  • Extra Mint Aero


  • 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 – stir till smooth!
  • Alternatively, add the syrup and butter to a pan and melt. Add in the chocolate (off heat) and stir till 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. Supermarket colouring doesn't work - I recommend a good quality colouring such as progel, or sugarflair!
  • Sprinkle on the crushed Mint Aero pieces so they stick and refrigerate again till set.
  • Chop up the pieces into either 4×4 for 16 larger pieces, or 5×5 for 25 smaller pieces. Enjoy!


  • 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 often use either Cadburys Milk Chocolate or Callebaut Milk Chocolate – Even supermarket own chocolate works well!
  • 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! Trust me!
  • This recipe will last in the fridge for up to two weeks, IF it happens to last that long!

    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 🙌

  2. Nicky on June 14, 2023 at 4:52 pm

    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

    Hi Jane! Lovely recipe! I wanted to know what else we can use instead of golden syrup for this recipe ?

    • Jane's Patisserie on June 21, 2021 at 9:38 am

      Hiya, aw thank you!! For the base of this recipe golden syrup is essential x

    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 🙂

  13. Faye Amelia on September 9, 2020 at 6:47 pm

    Hi Jane,

    How many grams on mint aero bubbles did you use? Thank you xx

    • Jane's Patisserie on September 9, 2020 at 8:16 pm

      300g mint aero used in the recipe as mentioned, and then any extra you want to decorate the top!

  14. Curtis on August 19, 2020 at 2:53 am

    How long do you have to leave it in the fridge for it to be completely done?:)

    • Jane's Patisserie on August 19, 2020 at 12:00 pm

      I would say a couple of hours, but sometimes it can set quicker for others xx

  15. Emily Gray on August 5, 2020 at 7:21 pm


    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

    • Jane's Patisserie on August 5, 2020 at 9:26 pm

      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

  16. Roseanne on June 6, 2020 at 8:25 pm

    I can’t find green food colouring anywhere can I add green icing to the white chocolate instead??? Thank you ☺️

    • Jane's Patisserie on June 6, 2020 at 8:27 pm

      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.

    • Jane's Patisserie on June 3, 2020 at 10:47 am

      Unfortunately that can happen with poor quality colours (supermarket ones) – I have linked on the post to the one I recommend!

  18. Bryony on May 21, 2020 at 9:47 pm

    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

    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

    • Jane's Patisserie on August 5, 2018 at 8:05 pm

      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

  23. Julia Barrett on July 29, 2018 at 4:11 pm

    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

    What do u mean by a double boiler? Thanku

    • Jane's Patisserie on January 6, 2018 at 8:13 pm

      Its a heatproof bowl, above a pan of boiling water. Its worth a google.

    • Nikki on March 14, 2024 at 11:45 am

      If I half the recipe do I need to use a smaller tin to make it in?

  28. Wendy on December 14, 2017 at 10:33 am

    I love this recipe, tastes so yummy. Are you able to freeze it?

  29. Wendy on December 14, 2017 at 10:19 am

    This is so nice, thank you. Just wondering though – can you freeze it?

  30. Mandi on November 9, 2017 at 7:38 am


    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

  31. Alyssa on October 14, 2017 at 3:07 am

    What are digestives? When I hear digestives I think Tums or Enzymes. I am confused here. Thanks for your help.

  38. Mandi on March 11, 2017 at 1:07 pm

    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

    • Jane's Patisserie on March 11, 2017 at 1:54 pm

      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!

  39. Sam on August 11, 2016 at 3:46 pm

    Hi, I’m currently in the process of making this now! How long does it normally take for the base to set?

    • Jane's Patisserie on August 11, 2016 at 3:47 pm

      Can take a few hours to set fully in the fridge!
