Instructions

1. Line an oven tray with baking or parchment paper. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced.
2. In a large mixing bowl, add the egg white and sugar and whisk together until smooth, approximately 1 minute or so. Then add your vanilla and mix again. Then add your melted butter and mix again.
3. Sift in your cocoa powder and flour and gently stir until a chocolate batter forms. Throw in your chocolate chips. Finally, add the milk and vegetable oil and stir gently until smooth.
4. Pour your brownie batter onto your prepared tray and spread out to form a large rectangle. Bake for approximately 15-20 minutes (15 minutes for a more chewy bark, 20 for a more crisp bark). Leave to cool completely.
5. Melt your chocolate in the microwave, stirring in between 15 second bursts, until smooth. Drizzle your chocolate over your bark, press your M&M candy on top while the chocolate is warm. Leave for 10-15 minutes for the chocolate to set, then cut into slices.
