Servings: 16 brownies


  • 150 grams butter 1.3 sticks
  • 125 grams dark chocolate 4.4 oz
  • 1 cup sugar to taste
  • 3 eggs
  • 1 tsp vanilla extract
  • 1 cup plain flour
  • 3/4 cup cocoa powder
  • 1/2 tsp salt
  • 3 tbsp smooth peanut butter


  • Preheat the oven to 350f/180c. Line a square baking tin with parchment paper. Use two long strips in a + shape so that you have handles to lift the brownies out later!
  • Add the chocolate and butter to a microwave safe mixing bowl and heat until melted. Alternatively, melt in a bain marie.
  • Once the chocolate and butter are melted, add in the sugar and whisk well for 1-2 minutes.
  • Whisk in the eggs and the vanilla.
  • Fold in the cocoa powder, flour and salt. Mix well, the batter should be very thick.
  • Spread the batter in to the prepared pan, using a spatula or spoon to spread it in to the corners.
  • Dot the peanut butter on top of the brownies and use a spoon or knife to swirl through the peanut butter and brownie mixture in figures of 8 until marbled.
  • Bake for roughly 25 minutes. To check if they are done, jiggle the pan, if the centre wobbles, give them a few more minutes.
  • Remove from the oven and allow to cool completely in the pan before lifting out and cutting in to 16 squares.
