Easy to bake chocolate chip s’mores cookies stuffed with a homemade marshmallow and chocolate spread – YUMMY!

So when I say I am obsessed with baking cookies, I am not exaggerating… it’s an absolutely obsession that I don’t think will ever end. And these cookies?! Well they just about top it. 

When I posted my raspberry cheesecake cookies and my banoffee sandwich cookies you guys went absolutely mad for them, so I thought I’d jazz it all up s’mores styley. 


So according to wikipedia “A s’more is a campfire treat popular in the United States and Canada, consisting of one or more toasted marshmallows and a layer of chocolate sandwiched between two pieces of graham cracker.” and there it basically means its something utterly delicious. Biscuit, chocolate and marshmallow?! What more could you want?! 

I have a few s’mores based bakes on my blog so far such as my s’mores cookie bars, and even my s’mores cake, but I wanted to level things up slightly and do a s’mores cookie with a homemade marshmallow stuffed inside. 

It’s obviously not classic s’mores, but it’s the idea behind it of a biscuit, marshmallow and chocolate just levelled up so much and I am utterly in love – and I am sure you will all love these too. 

Cookie dough

The cookie dough is a basic chocolate chip cookie that you can get from my NYC chocolate chip cookie recipe, or other cookies on my website. They’re measured with a 5cm scoop to bake to get a consistent size of cookie. You don’t want them too large as you have to sandwich two cookies together and that really would be overload if you used NYC size. 

As you don’t need the giant chunky size of cookie, I don’t chill the cookie dough. I make it, scoop it, and bake it and cool. I just want them to spread ever so slightly to be a good sandwich size. 

Chocolate chips 

For the chocolate chips I just went for a mix of milk and dark chocolate chips as they are my favourite. I know you don’t need to use chocolate chips in a cookie, but they just bring it up to a new level for me and I can’t help myself. 

You can of course, just like always, use whatever chocolate chips you fancy in this part of the recipe – use milk, white, dark, a mixture or whatever! I don’t judge – you do you, boo. 


The marshmallow is probably the most important part of this recipe as the cookie is similar to my other cookies, and this is the bit that makes up the s’mores. In my s’mores cookie bars I use marshmallow fluff, which is still very good to use, but I wanted to make a homemade marshmallow this time. 

The quantity this makes can be too much – but it’s harder to make a small amount. You can enjoy it on so many other bakes as well, or just devour it with a spoon which I will also recommend. You can half the recipe, but you just have to be conscious of the fact that the ingredients are such a small amount it may not work perfectly. 

I know it sounds faffy, but it’s worth it. It’s like a marriage of a meringue recipe, and an Italian meringue – make a delicious marshmallow. I have a marshmallow recipe in my first book which is completely different and set – this is meant to be piped more like a frosting. 

Using a thermometer makes this so much easier and so much more guaranteed to work. Also, electric whisks will absolutely save your arms. You need to whisk the meringue and then continue to whisk it whilst your sugar syrup heats up, and then you need to whisk whisk whisk to make the marshmallow and let it cool slightly. 


So in a classic s’more, you have a solid piece of chocolate that melts. In these cookies, you have the chocolate chips already, so I decided to use a chocolate spread to add a softer chocolate element to the s’mores cookies. 

You can use any chocolate spread really – nutella, chocolate, or even go wild and use biscoff – its completely up to you! I don’t mind, and I have tried basically all combinations at this point. I piped my chocolate spread on, but you can of course just slather it. 

Tips and Tricks 

In this recipe I used:

These are indulgent cookies, but they are worth it. The marshmallow is best fresh, but can go into the fridge for 2 days or so. 

The cookies on their own can last 4-5+ days, or freeze 3+ months.

  • 125 g unsalted butter
  • 100 g light brown soft sugar
  • 75 g granulated sugar
  • 1 medium egg
  • 1 tsp vanilla extract
  • 300 g plain flour
  • 1.5 tsp baking powder
  • 1/2 tsp bicarbonate of soda
  • 1/2 tsp sea salt chunks
  • 150 g milk chocolate chips/chunks
  • 150 g dark chocolate chips/chunks


  • 3 medium egg whites
  • 100 g caster sugar (for meringue)
  • 1 tsp vanilla extract
  • 100 g caster sugar (for syrup)
  • 65 ml water


  • 200 g chocolate spread



  • Preheat your oven to 200ºc/180ºfan, and line two-three trays with parchment paper.
  • Add the unsalted butter, light brown soft sugar and granulated sugar to a bowl and beat until creamy.
  • Add in the egg and vanilla extract and beat again.
  • Add in the plain flour, baking powder, bicarbonate of soda and sea salt and beat until a cookie dough is formed.
  • Add in the chocolate chips and beat until they are distributed well.
  • Scoop the cookies using a 5cm scoop onto lined trays.
  • Bake in the oven for 11-13 minutes, or until golden.
  • Remove the trays from the oven and leave the cookies to cool fully on the trays.

Marshmallow Frosting

  • Add the egg whites to a large bowl and start to whisk to stiff peaks
  • Add the 100g of caster sugar, 1 tsp at a time, whilst whisking.
  • Once all the sugar is in, whisk in the vanilla and leave the meringue to whisk on a slow speed just to keep it moving and stop it from sitting.
  • Whilst this is whisking, add the other 100g of caster sugar to a pan with the water. Heat this on a low heat to dissolve the sugar.
  • Once the sugar is dissolved, turn up the heat and boil the mixture to 113ºc.
  • Once heated, turn the whisk up high again and trickle the syrup into the meringue to make the marshmallow. Once all the syrup is in, whisk for a further 5 minutes.


  • Pipe the chocolate spread onto half of the cookies, and then pipe the marshmallow on top.
  • Sandwich the cookies together and enjoy!


  • You can freeze the raw cookie dough easily, and bake from frozen if you don't want to bake the entire batch - add 1-2 minutes to the baking time. 
  • Once baked, these will last for 3-4+ days, in the fridge.

  3. Danielle on July 17, 2023 at 10:54 pm

    As I don’t have a thermometer to make marshmallow

    • Jane's Patisserie on July 18, 2023 at 1:04 pm

      You can use marshmallow fluff, but actual marshmallows won’t work!

      Hiya! The marshmallow may not work if the temperature is incorrect, but its worth a go! x

  10. Andrea on December 18, 2022 at 12:54 pm

    Hi, Jane. When it says scoop with a 5cm scoop onto lined trays, do you flatten them out? Thank you!

    • Jane's Patisserie on December 23, 2022 at 11:17 am

      Hiya! No – they will flatten whilst baking! x

    • Kaya on May 18, 2023 at 1:55 pm

      Hello, I’ve made a batch of the marshmallow, how can o store it please? Is it ok in the fridge or will it go watery?

  11. Andrea on December 17, 2022 at 2:34 pm

    Hi Jane! Which marshmallows are the best to buy incase you do not have enough time to make them?
    Thank you!

  12. Gina on October 31, 2022 at 10:53 am

    Hi, Jane can you still use the fluff for these to save making marshmallow?

    • Jane's Patisserie on November 3, 2022 at 8:21 pm

      Absolutely you can, it may be harder to work with though! x

  13. Sally on October 27, 2022 at 11:24 am

    Hi Jane, my cookies came out like balls and didn’t spread, is this down to me not mixing the butter/sugar for long enough?

    • Jane's Patisserie on October 27, 2022 at 3:20 pm

      Hiya! This can be due to overworking the dough, rolling the balls too tightly, or your oven may be too hot. Hope this helps! x

  14. Betty on October 26, 2022 at 2:39 pm

    Is the marshmallow Safe using raw egg?

    • Jane's Patisserie on October 27, 2022 at 3:15 pm

      Hiya! Yes is it, and its delicious. Enjoy! x

  15. Vicki on October 25, 2022 at 11:59 am

    • Jane's Patisserie on October 27, 2022 at 3:07 pm

      Hiya! I would weigh them – it will make 16 separate cookies, 8 sandwich cookies! Hope this helps! x

    Wow the S’mores Cookies look and sound scrumptious what a treat, I’ve never tasted these goodies before I’ve got to rectify this and make some I’m not too keen on marshmallow is their anything else that I can possibly use to sandwich the cookies together?
    Would biscoff spread work or is that not suitable, many thanks Jane Tia.

    • Jane's Patisserie on October 27, 2022 at 2:57 pm

      Hiya! You can use whatever you like – maybe a buttercream? They will just be less s’mores – like! Hope this helps! x

    • Nichola on January 13, 2023 at 4:10 pm

      Hi if I don’t want to make my own marshmallow can I use fluff? If so do I need to anything to it or just put into the piping bag.
      Thank you

    • Jane's Patisserie on January 16, 2023 at 1:46 pm

      Hiya! This should be fine to pop straight into a piping bag! Hope this helps! x
