Cookie recipe – white chocolate, macadamia nut and marshmallow cookies.

I made these yesterday and OH MY GOD they are amazing. I adapted a simple cookie dough recipe for what I needed and struck gold. I shared the picture on social media with loads of people asking me how to make them so here is what I did! 

Pre-heat oven to 180 deg (or 160 fan). Line 2 baking trays with greaseproof baking paper.


  • 125g butter (I used Stork with butter, but simple softened unsalted butter would be just as good)
  • 100g light brown sugar
  • 125g caster sugar
  • 1 medium sized, beaten egg
  • 1tsp vanilla extract (I used Dr Oetker’s Madagascan vanilla extract, my advice is not to cut corners with this, use the best quality you can afford)
  • 225g self-raising flour
  • pinch of salt
  • 100g white chocolate chips
  • 50g macadamia nuts, crushed (with a rolling pin or similar)
  • 70g mini marshmallows.

What to do:

  1. Add the caster sugar and light brown sugar into a large mixing bowl and stir until combined together evenly.
  2. Add the butter and cream with a hand whisk until light in colour and fluffy looking (about 2 minutes).
  3. Put in the egg and vanilla extract followed with about 1/3 of the flour and whisk until combined.
  4. Slowly add the remaining flour and the salt and mix until a dough is formed.
  5. Using a spatula fold in the chocolate chips until evenly distributed, followed by the marshmallows and macadamia nuts.
  6. Once all combined evenly using a spoon or your hands to make into ping pong sized balls and place 6 on each baking tray. Make sure there is plenty of space between them so they don’t all join together whilst baking.
  7. Place in the oven for 10-14 minutes, checking regularly after the 10-minute mark to see when the dough is just cooked through, with a clean knife or skewer. You may find just a small bit of dough on the skewer when testing, at this point remove them from the oven. They will appear very puffy and the edges should be a light golden brown when they are ready.
  8. Let them cool on the baking tray for at least 10 minutes, by this time they should have flattened and appear gooey. Using a spatula remove them from the baking tray and onto a wire rack to cool completely.
  9. Enjoy! They should be delightfully gooey and break apart easily.
