Pre-heat oven to 160˚C. Line a shallow 30cm X 20cm or deep 23cm square cake tin with baking paper.
Place all remaining ingredients into a food processor and process until smooth — do not over process.
Pour mixture into prepared tin and smooth the top surface.
Bake for approximately 45 minutes or until the cake springs back when lightly touched and a wooden skewer comes out clean when inserted. Remove from oven and allow to cool on a wire rack.
