I have cooked this cake many times as it is so easy and always turns out super moist and everyone always asks for the recipe. So finally, here it is:
Mix: 2 cups SR flour, 1 cup desiccated coconut, 1 cup caster sugar, 1 cup tinned crushed pineapple, 3 eggs, 150 gms melted butter. Just hand mix or a quick whizz with the electric mixer.
Cook in a 190 - 200 degree oven in a large pan for about 1.15 hours or if you use smaller pans or cupcakes perhaps about 45 minutes. This time and heat varies of course depending on the size pan and your oven.
The icing and the filling is usually butter cream with some pineapple juice and crushed pineapple instead of any other liquid (save about 2 tablespoons from the can used in the cake). Lemon cream cheese frosting would also be lovely. For Evie's 3 tier birthday cake I then scattered the cake with coconut.
