Deliciously Chocolatey and Minty, Mint Aero Brownies!

Recipe Updated September 2020

Right, I know I like brownies. This is evident if you look at my recipe page, as there are quite a few now… Also, I realise the recipe is basically the same thing but swapping the different chocolate or theme, but I don’t mind. I love any excuse to bake.

It might not make sense to a few people as to why I post some similar recipes, but if someone googles ‘Mint Aero Brownies’ my Terry’s Chocolate Orange Brownies isn’t going to appear on the list of links, so people won’t look at my blog. Therefore, I like to post recipes on themes such as Mint Aero that people want to try, and as I had had a good few requests for these beauties, I thought I would oblige!

I decided to use the Mint Aero Bubbles in these Brownies, as I had 6 packets in my cupboard already, and they needed using up. You can use the bar and chop them up, or you can switch to a different flavour of Aero such as just the chocolate one, or the orange one etc! I used Peppermint Essence as well to make it extra minty but then used Dark Chocolate Chips as the extra chocolatey kick so that they weren’t too sweet.

The base of the brownie is so important to the success of the brownies it’s crazy. People really underestimate it, until they give them a go and they realise that either they are going to turn out like a cake, or they will turn out raw.. or perfect. 

The base mixture is six main ingredients… DARK CHOCOLATE (of which I recommend 70% cocoa content or darker), unsalted butter or a baking spread, eggs, sugar, flour and cocoa powder. The process does sound a bit intense, but it really is just six ingredients separated into three. 

You really need to use dark chocolate on the base for the best results. No, it won’t taste ‘dark’ to all you dark chocolate haters out there… but it will make them the best and fudgiest brownies ever. TRUST IN THE DARK CHOCOLATE. 

You melt the chocolate and butter together until smooth – you can do this on the hob with a double boiler/Bain Marie, or in the microwave as I do. You just want to melt them and stir them together until smooth. You then need to let them cool for about 10 minutes. 

Next, you need to whisk the eggs and sugar together – I use my stand mixer for ultimate ease, but an electric hand whisk, or even just your arm and a balloon whisk work, it will just take a lot longer. You want the texture to be double the volume it originally was, a lot lighter in colour, and for the trail of the mixture to stay for a couple of seconds before disappearing. 

After this, you FOLD CAREFULLY. Fold the cooled chocolate mix in, then fold the flour and cocoa powder. Simple, easy, and the best way to get the perfect brownie. This is when the alterations come in to fit these Mint Aero Brownies… peppermint extract, chocolate chips, and mint aero!

You can 100% freeze the mint aero if you are worried.. I wouldn’t say it’s essential, as long as you don’t need to bake the brownies for longer than advised. Mine took 28 minutes in the oven, and I got plenty of minty delicious mint aero bubbles left!

One of the best ways to tell if they are done is for a slight wobble in the mixture – but nothing major. I don’t often find the skewer test useful as melted chocolate can look like raw batter, but if a skewer is absolutely covered then they are not done.

I baked mine till they wobbled slightly, let the tin cool, then decorated and put the brownies in the fridge overnight. Best fudgiest mint aero brownies ever! You don’t have to put them in the fridge at all, but it makes them easier to cut in my opinion, and creates that solid but gooey texture you want!

Finally, because I can never resist decoration like my Mars Bar Brownies and Crunchie Brownies, I drizzle over some melted chocolate and sprinkle over some more crushed Mint Aero as well… I honestly, (and I realise I say this a lot as well) LOVE these brownies, but if you’re a mint and chocolate fan, you’ll love these too! Enjoy!

(The recipe has been updated, the original recipe was very similar (the base recipe used 195g butter/chocolate, and 90g flour, 35g cocoa powder), and it had frosting on top. If you would still like to make the frosting it was 125g unsalted butter, 250g icing sugar, 1tsp peppermint extract and a small amount of green food colouring!)

Author: Jane's Patisserie



  • 200 g Dark Chocolate
  • 200 g Unsalted Butter
  • 3 Large Eggs (or 4 medium)
  • 275 g Caster Sugar
  • 100 g Plain Flour
  • 50 g Cocoa Powder
  • 1 tsp Peppermint Extract
  • 200-300 g Mint Aero (freeze for 1 hour if you can)
  • 200 g Chocolate Chips/Chunks (optional)

Optional Decoration

  • 50 g Milk Chocolate Melted
  • 50-100 g Mint Aero (chopped)


  • Preheat your oven to 180C/160C Fan and line a 9x9" baking tin with parchment paper!
  • Melt together your dark chocolate and unsalted butter until smooth in the microwave or in a bowl over a pan of simmering water. Leave to cool for a few minutes
  • Using an electric whisk/stand mixer, whisk your eggs and sugar together for 5 minutes or so on high speed, or until the mixture has doubled in volume, is alot paler, and leaves a trail for a few seconds when you lift the whisk out.
  • Pour in the chocolate/butter mix and peppermint extract and fold through very carefully.
  • Add in the flour and cocoa powder and fold through carefully again.
  • Add in the Mint Aero and chocolate chips and fold in. Pour the mixture into the tin!
  • Bake in the oven for 25-30+ minutes. Sometimes it can take longer.
  • Leave to cool in the tin!
  • To decorate your brownies if you fancy it... melt your chocolate and drizzle over the brownies, and add sprinkle over chopped pieces of Mint Aero!
  • Then, if you want, put them in the fridge for a couple of hours to help 'set' them, and then enjoy!


  • Try and freeze the mint aero for at least an hour before baking, but it is not essential. 
  • These will last for one week+!
  • I use this tin for all of my brownie baking!
  • I love this peppermint extract
  • I use this dark chocolate in my brownie base.. 
  • And I love these chocolate chips for the filling and top!
  • If your brownies are taking much longer than stated to bake, your oven may have been the wrong temperature, or you overmixed your batter. Keep adding on 5 minutes till they're done and cover with foil if need be!
  • The recipe has been updated in September 2020, the original recipe was the same (195g chocolate/butter) apart from it had a frosting on top. If you would still like to make the frosting it was 125g unsalted butter, 250g icing sugar, 1tsp peppermint extract and a small amount of green food colouring!

    I made these yesterday and have left them to ‘set’ in the fridge overnight. When I have cut them today they seems quite gooey/wet, is this how they are suppose to be or have I just not baked them for long enough. I ended up baking them for 30 minutes.

    • Jane's Patisserie on January 17, 2024 at 2:33 pm

      It depends on your oven, and if you used dark chocolate with a high enough cocoa content, and use the correct size tin, but they are meant to be ‘fudgey’ so have a bit of a goo to them. If they are still very wet after being in the fridge overnight, they may have needed a little bit longer X

  2. Melissa on November 25, 2023 at 10:04 am

    I want to have a go at baking these , however my past brownies have sunk in the middle! Please help me 😞.

    • Jane's Patisserie on December 1, 2023 at 11:41 am

      This likely means they are underbaked or too much air is in the mix x

    I made these yesterday for my boyfriend’s birthday and they were AMAZING!! All our friends loved them. They are so rich, I had to cut them into smaller slices, which was perfect. Will they freeze?

    • Jane's Patisserie on September 26, 2023 at 8:37 am

      Yes, they do freeze! So glad you liked them!

  4. Sim on May 31, 2023 at 3:15 am

    These look fabulous!! Would a 8x8inch tin be okay to use? If so, how do I adjust baking time? Thanks!!

  5. John on February 9, 2023 at 10:10 am

    Can you do these in an air fryer?

    Wonderful recipe!

    Just wondered if you could use dark chocolate to drizzle on the top instead of milk chocolate?

    • Jane's Patisserie on February 3, 2022 at 12:45 pm

      Hiya! Yes absolutely you can! Enjoy! x

  7. Neil McCarron on October 4, 2021 at 1:51 pm

    Followed recipe to the letter,
    It was nowhere near done at 25 mins,
    Put it back in till I could put a cocktail stick in and take it out clean,
    Then it sunk in the middle… gutted 😭

    • Jane's Patisserie on October 6, 2021 at 9:30 am

      The cocktail stick/skewer test does not work with brownies – you need to bake until there is a slight wobble in the middle and then chill the brownies fully before testing. I always bake mine to exactly 25 minutes and they come out perfect!

  8. Rosie on September 22, 2021 at 1:21 pm

    What am I doing wrong with mine?
    My mint areo is just melting into the brownie they ain’t no green what so ever in mine apart from the crumbs that’s on the top

    • Chloe on September 29, 2021 at 5:08 pm

      From reading the notes for the recipe, i assume it would be best to freeze the aero bubbles for an hour before making? That might be what is stopping them from melting?

  9. Charlene Knight-Whitmore on August 9, 2021 at 8:41 pm

    Hi Jane

    I’m loving some of your recipes do you have a recipe for m&m Brownies please

    • Jane's Patisserie on August 13, 2021 at 2:55 pm

      Hiya! Unfortunately I do not yet, but I will add it to the list. You could try my M&M Cookie Bars in the mean time!x

    Hey!! Can I make this recipe without the pepper mint extract??? X

  14. Ellie on April 28, 2021 at 10:48 am

    Hey! Could I use after eight chocolate instead?

    Hi Jane,

    I made these brownies and they turned out AMAZING! (Even the people I work with who don’t like mint chocolate thought they were great!) I was wondering if it would be possible to add Nutella to this recipe with slightly less dark chocolate/cocoa powder?


    • Jane's Patisserie on April 29, 2021 at 10:24 am

      For the base brownie I wouldn’t change it – you can add Nutella in as a flavour swirled into the brownie mix, but not change the base x

  16. Rosy on March 1, 2021 at 10:12 am

    Hi Jane
    Thank you for all of your amazing recipes. If I ever want to try anything new, your recipes are always the ones I go to!
    I was wondering if I could use frozen squares of mint aero for the decoration instead? So 5 minutes before the total bake time pop them on and finish baking? Or would it be a melted mess due to the type of chocolate it is?

    • Jane's Patisserie on March 1, 2021 at 10:06 pm

      It’s a hard one – they should be fine (As long as you have perfected your brownie bake time!) X

  17. Sumaiyah on February 19, 2021 at 8:23 pm

    Can I use light brown sugar instead of cater sugar for this?? Will it taste better?

    • Sumaiyah on February 19, 2021 at 8:24 pm


    • Jane's Patisserie on February 20, 2021 at 11:51 am

      Yes you can!

  18. Charlotte on February 16, 2021 at 7:10 pm

    I made these yesterday for my daughters birthday, I’ve always wanted a good recipe and it seems that anyone that makes a really good brownie never wants to give you it. Well I don’t need one anymore, these were amazing, I made them with the trip choc cookies, also amazing, and it all looked so impressive on a platter.

    My 15 year old wanted to make his girlfriend some mint brownies. I recommended your site for a recipe for him to use and off he went to whip them up. They taste amazing, nice and fudgey and the mint is just right. Not good on my waistline though. Your site is always my forst stop for recipes. Keep up the good work x

  20. P on January 18, 2021 at 4:07 pm

    Hi Jane,
    How do you stop your Aeros from melting completely? I get they were melt and deform a bif as the brownies bake but i tried a similar recipe yesterday with Lindt balls and the chocolate melted completely. Not sure if I need to turn the temperature down and left them bake for longer.

    • Jane's Patisserie on January 18, 2021 at 8:08 pm

      I just do exactly what is written on the recipe – There are notes on the post about freezing the aero too x

  21. Phoebe on January 7, 2021 at 2:28 pm

    Hi Jane can I use granulated sugar instead of caster?

    • Jane's Patisserie on January 7, 2021 at 2:35 pm

      I don’t use granulated sugar in brownies personally as I find it can cause a problem with the whipping stage of the eggs/sugar but its worth a go x

    • Charlene Knight-Whitmore on August 12, 2021 at 12:12 pm

      Hi Jane do you have a recipe for m & m Brownies please or could you swap the aero for m&ms

    Amazing chewy brownies. First time trying this recipe and they are a big hit!

  23. Charlotte Levy on November 12, 2020 at 6:35 pm

    Hello, these look amazing! I noticed that there is peppermint extract in the ingredients but I can’t see where you add it?


    • Jane's Patisserie on November 13, 2020 at 11:25 am

      Oops! Just add it when you add the dried ingredients, or the chocolate and butter to the eggs xx

  25. Mckayla on October 9, 2020 at 5:00 pm

    Can I use milk chocolate instead of dark chocolate and can I use milk chocolate if I can’t get chocolate chips

    • Jane's Patisserie on October 9, 2020 at 5:51 pm

      You must use dark chocolate (at least 70% cocoa content) for the brownie, but you can use chopped up milk chocolate for the chips yes.

  26. Kimberley hill on October 9, 2020 at 11:59 am

    Hi, could I double the recipe? I want to do half mint for us and Oreo for my daily free daughter in a large tin.

    Thank you!

    • Jane's Patisserie on October 9, 2020 at 4:01 pm

      You can double the recipe – but it depends what size tin you are using as if you mean to bake double the recipe in one it may not bake so well x

  27. Rebecca Carpenter on October 3, 2020 at 11:02 pm

    Hey Jane!

    Made these last night! Super tasty and recipe so easy to follow!

    Even after putting them in the fridge, mine were pretty crumbly, what do you think caused that so I can change for next time?

    Thank you xx

    • Jane's Patisserie on October 4, 2020 at 9:57 am

      It depends on what you mean by crumbly – were they too soft crumbly, or too dry, or were they not cut carefully enough? xx

    • Emily on July 17, 2021 at 11:20 pm

      Hi, I love making brownies but struggle to work out when they will be done!

      What consistency should they be when they come out the oven as they set more when they cool don’t they? X

      Thank you

    Hi Jane, I stumbled across your site and I absolutely love with your recipes. The only thing I struggle with when baking is finding a good egg substitute, do you know what I can use instead of eggs? , I can eat dairy but I’m allergic to eggs

    • Jane's Patisserie on September 30, 2020 at 8:36 am

      I tend to find it’s better to follow an egg free recipe, rather than replace them – so maybe use my vegan brownies, but use dairy milk for example? x

  29. Amy Campbell on September 24, 2020 at 10:49 am

    Tried these they are amazing!!
    Quick question, if I wanted to try these with gluten free flour, should I adjust measurements of any of the wet ingredients?

    • Jane's Patisserie on September 24, 2020 at 12:05 pm

      I would just do a straight swap!

  30. Holly on September 17, 2020 at 4:04 pm

    Hi Jane,

    2 questions 🙂

    1 – can I use stork instead of unsalted butter?
    2 -is there a way I can make these blondies instead of brownies?


    • Jane's Patisserie on September 17, 2020 at 7:40 pm

      Yes you can use stork – and you can’t follow this recipe for blondies. You’d need to look at my blondie recipes x

    Ooh it’s been a while since I’ve made the mint aero brownies!! The Terry’s chocolate orange ones are just amazing I have to say and I love all things mint aero too so will definitely be making these again soon 😊😋

  32. Lizi on September 6, 2020 at 11:37 am

    Hi Jane, absolutely love these and your choc orange brownies, made a few Of your recipes now and all fab. Just wondering can you freeze any brownie and blondie?

    • Jane's Patisserie on September 7, 2020 at 2:48 pm

      Hey! Ahh yay! yes you can freeze them all x

    • Alison on September 16, 2020 at 2:19 pm

      Hope you don’t mind me commenting – I find the brownies and blondies freeze really well. I do this quite often if I’m making a couple of batches for work! They’re just as nice when they defrost as if they were fresh from oven 😋😊

  33. Emily Gray on August 5, 2020 at 7:14 pm

    So excited to make these. Just wondering for the topping did you use crushed aero bubbles or just standard aero chocolate bar? Want it to look at perfect as yours 🙂

    • Jane's Patisserie on August 5, 2020 at 9:27 pm

      Umm I think they were the bubbles, but honestly either works the same! x

  34. Michelle on May 15, 2020 at 9:35 pm

    Hi, I’m going to make these for my birthday 🤪🤗 Is it ok to use milk chocolate chips instead of dark, or will it be far too sweet? I do have a sweet tooth 😋

    • Jane's Patisserie on May 16, 2020 at 9:18 am

      For the brownie batter, you need to use dark chocolate – it doesn’t make them bitter! But for the what you add to them yes you can use milk chocolate! x

  35. Charl on April 28, 2020 at 7:20 pm

    Oh. My. Life!!! These are amazing 😍 they took about 45 mins in my oven and they are the chewiest loveliest brownies! I didnt have any peppermint so just used extra mint aero and less chocolate chips but worked perfectly

    • Elaine Syme on July 4, 2020 at 1:49 pm

      I didn’t have any peppermint so I used Creme de menthe…very adult brownies and delicious !!!
