Preheat the oven to 180°C. Line a 20 cm round cake tin with baking paper.
Combine all the ingredients in a large bowl and mix well. Pour the batter into the tin.
Bake in the preheated oven for 1 hour or until a cake tester inserted into the centre of the cake comes out clean. Cool.
Serve with extra pineapple slices and yoghurt, or ice with cream cheese icing
