Total Time: 40 minutes
Servings: 16 brownies


  • 125 g dark chocolate 70% cocoa solids
  • 110 g unsalted butter
  • 1/4 tsp salt
  • 1 tsp vanilla extract
  • 200 g granulated sugar
  • 2 medium eggs
  • 65 g plain white flour
  • 16 oreo cookies

Mint chocolate drizzle

  • 75 g dark chocolate 70% cocoa solids
  • 1/4 tsp peppermint oil


  • In a medium saucepan, melt the chocolate and butter together over a low heat while stirring to prevent the chocolate from burning. Stir in the vanilla and salt.
    125 g dark chocolate, 110 g unsalted butter, 1/4 tsp salt, 1 tsp vanilla extract
  • Let the mixture cool for a few minutes while you preheat your oven to 200°C fan (400°F fan) and line an 8 or 9-inch (20 or 23cm) square pan with baking paper.
  • To the chocolate mixture, add the sugar and stir together well. Crack in the eggs one at a time, beating in quickly after each addition until really well mixed. Stir in the flour.
    200 g granulated sugar, 2 medium eggs, 65 g plain white flour
  • Pour 2/3 of the batter into the tin, and spread so it coats the bottom of the pan. Arrange 12 oreos evenly over the surface of the batter, pushing them down a little, to slightly submerge them. Cover the oreos with the remaining batter. Try to smooth the whole thing out a little by spreading the batter around or pushing the oreos down a little more if they start to float around. Bake for 20 minutes.

  • This step is optional but I really really really advise it!!: As soon as the brownies have baked, take the pan out of the oven and shove into the freezer on top of a tea-towel (and make sure the edges of the hot pan aren't touching anything plastic). This helps cool the brownies down very quickly so it results in a very gooey middle with a crunchy exterior.
  • Once the brownies have cooled completely, cut int 12 or 16 squares.
  • Crush up the remaining oreos (I put them into a sandwich bag and bashed them with a rolling pin in) and sprinkle over the individual brownies. Melt together the chocolate and peppermint extract and drizzle over the brownies*, letting it drip down the edges a bit to secure the oreo crumble to the brownie. Let cool and set.

*I  like to let the chocolate cool a bit, pour it into a small plastic sandwich bag then cut a very small amount of one corner of the bag off. It’s perfect for drizzling it a neatly as possible over the brownies.

  1. What happens to brownies if you do not cool on ice? I would like to serve warm with ice cream. They look wonderful. .

  2. Brownies are awful. They are way too sweet and gooey. You should make a Girardelhi brownie and add Oreos and mint instead of using this brownie recipe. 🙁

    • well actually i like them that way, taste is a personal preference. If you know that you don’t like them that sweet you could have reduced the sugar in the recipe yourself. If you didn’t want them that gooey, you could have baked them for a longer amount of time. I don’t think that the Ghirardelli brownie mix is either a) tasty b) available in the UK or c) the type of brownie I Like. they taste like chemicals (I have tried them because I’d heard ‘rave’ reviews of them and brought a box back with me when I went the US. They taste EXACTLY like Betty Crocker brownies. Not worth it at all), they contain chemicals, and are so over processed that you might as well go and buy a brownie from the supermarket rather than making them at home.

  3. Do you think these would be too overwhelmingly minty if mint oreos were used? If you don’t have mint oreos in the UK, I find them to be a pleasant mint:choc flavor ratio. These look amazing! I’m going to have to make them for my mint/choc-loving boyfriend.

    • I don’t think it’d be overwhelming – but if you think it is just reduce the amount of mint that you put into the chocolate drizzle and you’ll be fine!
