  1. Step 1

    Preheat oven to 180°C. Lightly grease a 20cm x 30cm lamington pan and line with baking paper, allowing the sides to overhang.
  2. Step 2

    To make the brownie, place the butter and chocolate in a small saucepan over low heat. Cook, stirring, for 4-5 mins or until the chocolate melts and the mixture is smooth. Transfer to a heatproof bowl. Stir in the sugar. Add the eggs and stir to combine. Add the flour and cocoa powder and fold until well combined.
  3. Step 3

    Whisk the oil, egg and combined sugar in a large bowl. Add the oats, raisins, flour, cinnamon and bicarbonate of soda and stir to combine.
  4. Step 4

    Spoon the oat mixture into the lined pan, alternating with the brownie mixture. Sprinkle with extra oats. Bake for 45-50 mins or until the surface is just set. Set aside in the pan to cool completely. Cut into pieces to serve. Store in an airtight container at room temperature for up to 3 days.

Recipe tip

Swap me: If you’ve got dried cranberries or glacé cherries to use up, add them to the mix in step 3 instead of the raisins.
