Ingredients

  • 150g unsalted butter, cubed, plus extra for the tin
  • 250g dark chocolate, chopped
  • 200g soft light brown sugar
  • 3 eggs
  • 100g left-over sourdough starter
  • sea salt flakes
  • 50g cocoa powder
  • 75g self-raising flour
  • 30g salted pretzels, broken into pieces

Method

  • STEP 1

    Heat the oven to 180C/fan 160C/gas 4. Butter a 20cm brownie tin and line with baking paper. Tip 200g of the chocolate, plus all the butter and sugar into a pan and set over a low heat, stirring until the chocolate and butter have melted. Remove from the heat and leave to cool slightly, then crack in the eggs, one at a time, whisking well in between each addition. Tip in the sourdough starter and a pinch of sea salt flakes, then mix to combine. Sift in the cocoa and flour, then use a spoon to fold everything together. Tip into the prepared tin, then scatter over the remaining 50g of chocolate and the pretzel pieces, along with a little more of the sea salt flakes, if you like.

  • STEP 2

    Bake for 20-25 minutes or until the top is cracked but there’s still a little wobble in the centre. Remove from the oven and cool in the tin. Remove to a board, then cut into squares.
