Australian Macadamias

For the cake, preheat oven to 180°C. Grease and line a 25cm x 40cm cake tray. Sift together the plain flour, baking powder and salt into a large bowl. Add the butter, macadamia oil and caster sugar to the bowl and beat with electric beaters until pale. Beat in the eggs, one at a time, beating well after each addition. Alternately add the milk and macadamias to the flour mixture, stirring to combine. Pour into the prepared tin and bake for 15-20 minutes, until cooked through when tested with a skewer. Cool in the tin for 10 minutes before turning out onto a wire rack to cool completely.
