Smartie Brookies Recipe!

Hello lovelies,

I’m not sure what person decided it would be a good idea to make a brookie, but I would like to personally thank that person on behalf of the nation for creating something so damn delicious that I’d actually go as far as saying that I truly believe they deserve a knighthood. Before you think it, I’m not being dramatic, it’s the damn truth haha.

If you’ve not seen or heard of a brookie before (where have you been?!), then I’m here to bring them to your attention today as I truly believe everyone NEEDS to know and have a brookie recipe in their life!

A brookie is two of the world’s most famous sweet treats, joined together to create utter deliciousness. The base is a chocolate crammed cookie dough with a chocolatey fudge brownie on top. If that doesn’t make your saliva glands fill and your tummy rumble, I don’t know what will.

I first came across a brookie recipe way back in 2020 when I was a newbie to the baking scene. I’ll be totally honest with you, I’ve had many failed attempts at a brookie over the last couple of years, I’ve just never mastered it to a point where I could share it with you all. That was until recently…

You all know one of my baking idols is Jane’s Patisserie. She just knows how to smash out an unbelievably yummy recipe, every. damn. time! So when I came across her brookie recipe on a nightly scroll through social media, I just knew it would be solid and that it was fool proof.

In which, I was right! I’ve finally mastered a brookie and what a ridiculously easy recipe it is to create. I had clearly never found the right recipe for me. Clearly… *wink wink*.

Therefore, today I’m taking Jane’s original brookie recipe and adding my own personal touches and boy, it is good!

So, if these brookies have caught your attention and got you wanting to create a batch of your own, you know the drill. Keep on scrolling below and you’ll find the recipe.

  • 125g Of Light Brown Sugar
  • 1 Medium Egg
  • 1tsp Of Vanilla Bean Paste / Extract
  • 225g Of Plain Flour

Ingredients You Need For The Brownie Layer:

  • 100g Of Dark Chocolate
  • 100g Of Unsalted Butter
  • 2 Medium Eggs
  • 140g Of Caster Sugar
  • 50g Of Plain Flour
  • 25g Of Cocoa Powder
  • 150g Of Milk Chocolate Chips
  • 1x 105g Bag Of Smarties

How To Make The Cookie Dough Layer:

  • Firstly, gather together your equipment and ingredients and line a 9” loose-bottomed square tin with parchment paper.
  • Secondly, a large bowl, using an electric whisk, beat together the 115g of unsalted butter with 125g of light brown sugar until light and fluffy.
  • Next, beat in the 1 medium egg and 1tsp of vanilla extract until smooth.
  • Now, fold through the 150g of milk chocolate chips and bag of smarties.
  • Add the 225g of plain flour, 1/2tsp of bicarbonate of soda and 1tbsp of cornflour and beat together until a cookie dough forms.
  • Evenly press the cookie dough into the bottom of the prepared baking tin.
  • Place into the freezer for 20 minutes or in the fridge for 1 hour (TIP: it is important to do this to allow the brookies to bake better).

How To Make The Brownie Layer:

  • Whilst the cookie dough is chilling, it’s time to make the brownie layer.
  • Preheat the oven to 180C / 160C Fan / Gas Mark 4.
  • In a microwavable bowl, add 100g of dark chocolate and 100g of unsalted butter, place into the microwave and in 20 second blasts, stirring well between each blast, blast the chocolate and butter until fully melted. Once melted, set to one side to cool to room temperature.
  • Next, in a large bowl, using an electric whisk, whisk together the 2 medium eggs and 140g of caster sugar into a thick, mousse-like mixture.
  • Add the cooled chocolate mixture into the egg mixture and using a spoon, fold together slowly until combined.
  • Now, fold through the 50g of plain flour and 25g of cocoa powder.
  • Carefully fold through the 150g of milk chocolate chips and 80g of smarties.
  • Once the 20 minutes is up, remove the cookie dough from the freezer and pour the brownie batter on top of the frozen cookie dough.
  • Add the remaining 25g of smarties on the top of the brownie batter.
  • Place into the oven and bake for 25-30 minutes, until baked through and there’s a slight wobble in the centre of the brookie.
  • When baked, remove from the oven and allow to cool completely in the tin. Once cooled, transfer the tin into the fridge and chill for at least 4 hours (this will give the brookie a fudgy texture).
  • Finally, once chilled, carefully remove from the tin and using a sharp knife cut into 12 squares.

That’s your Smartie Brookies prepared, froze, baked and chilled, ready for you to enjoy!


  • Store at room temperature, in an airtight container for 4-5 days.
  • You don’t have to use smarties in your brookies, you could just stick to the milk chocolate chips or switch it out for a chocolate you prefer. I personally think any chocolate would work beautifully in these.

These are definitely up there with one of the most indulgent bakes I’ve ever done but BOY, are they worth every calorie.

What I love about these brookies is that there’s nothing else like these in the baking world. Two of the most well known and loved bakes joint together to create something quite amazing – I mean, it’s genius!

Big shoutout to Jane, I’m obsessed and I think you guys will be too…

Let me know in the comments below if you make these brookies yourself and if you do, what your thoughts are on them. Are you a brookie fan?

Sending you all tons of love & hugs as always,

Elle xo

    I haven’t had Smarties for the longest time, but this seems like the best way to have them again—wrapped in a brookie (which is the baking combination I did not know I needed)!
