Chocolatey, Fudgey, Minty Oreo Brownies – the perfect delicious and easy bake that everyone will love!


Its the new year, you’ve all made those resolutions to eat better, be healthier.. maybe even go to the gym? Well these Brownies are truly irresistible and utterly delicious – have I caught your attention now? I know that I personally will never stick to a ‘be healthy and exercise’ diet as I love food too much, and I am lazy.. and I hope this recipes persuades you to the dark side like me! Seriously though – this is my go-to recipe for Brownies, I have never found one more successful than this one, and that’s saying something! They are chocolate, gooey, and minty Oreoy good- but I always think Oreo’s are a winner in general anyway, especially on social media, the public love them!

I based this recipe around my go-to recipe for brownies which I have posted a few variations of, including my Cookie Butter Brownies and my Chocolate Orange Brownies. This time, only using one type of Chocolate I simply HAD to use the delicious Mint Oreos that I found in the UK recently – to not use them in a recipe would be ridiculous. They are seriously SO DELICIOUS.


I always believe that Brownies are an all round winner even if you don’t like chocolate – you could make lemony themed, cheesecake flavoured, and Blondie themed! You could have them in a tin lying around the house, or use them for a delicious afternoon treat – seriously one of the best treats around. When cooking a dinner for my family and I am short for time, I often use brownies as my dessert with a dollop of homemade Ice-Cream or some Mascarpone Cream – SO YUMMY!

I found these Mint Oreo’s in my local supermarket it and oh wow it was so worth it. I might have accidentally broken my ‘Gluten-Free’ stint as I just couldn’t resist.. they’re so tasty! The marriage of the soft and gooey brownies, with the Milk chocolate Chips and the Mint Oreos is simply splendid. I had many many taste testers this Festive Season when I went to see some of my Boyfriends family – and I can honestly tell you that 16 people approved highly of them! Let me know how you get on if you bake them!


This recipe makes 16 brownies!


– 195g Unsalted Butter
– 195g Dark Chocolate, chopped ip
– 3 Large Eggs
– 275g Caster Sugar
– 90g Plain Flour
– 35g Cocoa Powder
– 1tsp Peppermint Essence
– 150g Milk Chocolate Chips
– 300g Mint Oreos, quartered



1) Preheat your oven to 180C/160C Fan and line a 9″ Square baking tray with parchment paper.

2) Melt together the Butter, and Dark Chocolate in a heatproof bowl over a pan of boiling water, on the microwave for 1-2 minutes until melted. Leave to the side to cool to room temperature!

3) Using an electric whisk/stand mixer, whisk together the Eggs & Caster Sugar for a few minutes until the colour has turned pale, is very mousse like, and is double the original volume of the amount of eggs + sugar! You will know its done because when you lift the whisk up out of the mix it should leave a trail for a couple of seconds before disappearing!

4) When whisked, pour the cooled chocolate mix over eggs and fold together carefully. It might take some time, but be patient – you don’t want to knock out the air you made up on the previous step!

5) Once completely combined, sift the cocoa powder, plain flour on top of the chocolate mix and then fold together again with the peppermint essence – still be careful to not knock out the air!

6) Once combined well, fold through the chocolate chips and 90% of the Chopped Oreos and pour into the prepared tin, sprinkle over the rest of the oreos – bake in the oven for 25-30 minutes! Once baked, leave to cool in the tin completely.


Tips and Ideas

I found a 450g Pack of Mint Oreos in Tesco recently, but if you can’t find them anywhere then obviously normal Oreos will do nicely!

Warm these up in the microwave and serve with some ice-cream, a delicious dessert for any occasion!

These will last in an airtight container for 1-2 weeks!

    Hi could I use an 8×8 square tin for this recipe? If so would baking times be relatively similar? Thank you

    • Jane's Patisserie on April 6, 2021 at 8:31 pm

      For best results you need to use the tin provided as the baking times can be quite different due to the depth change! x

    Hi Jane, could you use mint aeros instead of the oreos? x

  3. Amber on March 22, 2021 at 11:05 am

    Hi Jane

    I made this and it came you lovely! Only thing was the Oreos in the batter evaporated- do you know why this would happen?
    Thanks x

    • Jane's Patisserie on March 22, 2021 at 3:50 pm

      I don’t know how that happened unless they were really small!

  4. Rups on March 15, 2021 at 8:03 pm

    Hi Jane,
    First of all I just want to say thank you, because you’re blog has reignited my passion for baking from the past year ago.
    I have baked these brownies & the biscoff brownies, and what I noticed was, both the biscuits that i added to the batter had evaporated. When I cut through the brownies once cooled down you couldn’t see any biscuits. Although they tasted amazing there wasn’t much of the biscuit flavour, if you know what I mean?
    I followed the recipe to a tee, and I also have an oven thermometer so I know I cooked them at the right temperature.
    Do you know why this happened or what I might have done something wrong? Or any suggestions, because I would love to make them again x

    I have made these and oh my they are so delicious. I am just wondering if these can be frozen xx

  6. Michelle on July 30, 2020 at 2:50 pm

    Hi Jane, LOVE your recipes! I couldn’t find the mint essence anywhere in the shops. Will it matter if I leave this out? Thanks in advance x

    • Jane's Patisserie on July 30, 2020 at 3:41 pm

      Yeah it’ll be fine without – just slightly less minty!! x

  7. Hilary Davies on June 9, 2020 at 2:20 pm

    Hi, love your recipes. Do you ever double the quantity, if so which tin is best to use for the brownies. Thanks!

    • Jane's Patisserie on June 9, 2020 at 2:35 pm

      Hey! For double, I would personally bake into two 9″ tins. You can use a 9×13″ tin for 1.5x the recipe – but I just think too big a tin would mean a raw middle and over baked outsides! x

    • Kiran Devi on September 11, 2021 at 9:57 am

      How many eggs would you use to make half a batch please?

  8. Candy Cane Brownies! - Jane's Patisserie on April 1, 2018 at 10:51 am

    […] cane sprinkles, other sprinkles, and some mint extract in the brownies themselves. I’ve got Mint Oreo Brownies and Mint Aero Brownies already on my blog, but as they are green minty colour themed, I felt […]
