For the brownies:

For the peanut butter swirl:

  • 40 g unsalted butter
  • 100 g smooth peanut butter
  • 40 g icing sugar


  • Chop the butter and chocolate up into small pieces and put in a bowl. Microwave on high for 1-2 minutes until melted. Allow to cool.
  • Whisk the light brown sugar and eggs together for 3-5 minutes using an electric mixer, until it looks thick and creamy.
  • Pour the cooled chocolate and butter mixture over the egg and sugar mixture and fold it in gently until completely mixed.
  • Sieve in the flour and again fold in gently until completely incorporated, but do not overmix.
  • Grease and line your slow cooker bowl with grease proof paper.
  • Pour the brownie batter in.
  • Mix the butter, peanut butter and icing sugar together in a small bowl, until smooth.
  • Use a spoon to dollop it on top of the brownie batter.
  • Swirl it together with the brownie batter with a knife.
  • Cook on high for 2-3 hours until just set in the centre. Allow to cool completely before using the baking paper to remove from the slow cooker.


Note: Timings depend on your slow cooker. Check after an hour if you have a slow cooker that cooks fast (e.g. a sear and stew). If you have a slow one like me it could take 2-3 hours.
