Chocolate Chunk S’mores Brownies

Fudgey brownies, with crushed digestive biscuits inside and Marshmallow Fluff swirled through.
Prep Time 10 minutes
Cook Time 30 minutes


  • 1/2 cup melted butter (1 stick)
  • 1 cup caster sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • 1/3 cup good quality cocoa powder
  • 1/2 cup plain flour
  • 1/4 tsp baking powder
  • 1 cup milk/dark chocolate chunks, I used dark
  • 1 cup crushed digestive biscuits
  • 1 cup Marshmallow Fluff


  • Preheat the oven to 180 degrees C (350F) and grease and line your baking tin.
  • Place the melted butter, sugar eggs and vanilla extract in a large bowl or the bowl of your stand mixer and mix until well combined.
  • Sift in the cocoa powder, flour and baking powder. Mix until well combined, about 1 minute on medium speed.
  • Add in the chocolate chunks and crush digestives, mix until evenly distributed.
  • Place the marshmallow fluff into a heatproof bowl and microwave for 10-20 seconds. Fold into the brownie batter, but not fully, you want a swirled, marble effect.
  • Tip mixture into brownie pan and smooth with a spatula/wooden spoon.
  • Place in the oven for around 30 minutes until slightly puffy and an inserted skewer comes out with a few crumbs on.
  • Leave to cool completely in the pan. Once cooled transfer to a cutting board and slice into 9 or 12 pieces.
  • Brownies will keep in an airtight container for 3 days.
