Ingredients

  • 1 & 1/2 tbsp unsalted butter
    ¾ c
  • milk powder
    1 tbsp
  • white granulated sugar
    ½ c
  • soft light brown sugar
    ⅝ c
  • egg + 1 egg yolk
    1 large
  • all-purpose flour
    2 c
  • corn starch
    1 tsp
  • instant coffee powder
    1 tsp
  • baking powder
    ¾ tsp
  • fine salt
    ½ tsp
  • semi-sweet chocolate chunks
    7 oz

Directions

  1. 1

    Preheat your oven to 175°C and line your pan with parchment paper leaving an overhang on the sides.

  2. 2

    Melt the butter in a saucepan over medium heat, add milk powder, stirring occasionally, until the milk solids turn deep amber and the butter smells nutty. Pour into a large bowl and leave to cool for 10 to 15 minutes.

  3. 3

    Whisk both sugars into the cooled brown butter until smooth and glossy.

  4. 4

    Add the egg and egg yolk and whisk for a full minute until the mixture is thick, pale and ribbon-like.

  5. 5

    Add the flour, corn starch, instant coffee powder, baking powder and salt all at once. Fold gently until just a few streaks of flour remain.

  6. 6

    Add the chocolate chunks and fold through until the last flour streaks disappear and the chocolate is evenly distributed throughout the dough.

  7. 7

    Press the dough evenly into the prepared pan and bake at 175°C for 18 to 20 minutes until golden on top but the centre still looks just slightly underdone. Cool completely in the pan before slicing.
