Oven 160 deg / 320F. Grease and flour a bundt tin
Sift the flour, baking soda and powder together in a bowl and mix in the salt
Beat the softened butter with the 150 gm sugar (3/4 cup) till light and fluffy add eggs 1 at at time. You will need to add a little of the flour mixture after the addition of the second egg. So stop the mixer and add a couple of tablespoons and mix before adding the last egg and beating.
Add the rest of the flour and the liquids including the vanilla and mix . The mixture should be fluffy and not too thick. It should be easily spoonable.
Spoon into the tin and bake approx 35 minutes.Or until the cake springs back when touched on the surface. Alternately use a skewer to test if it comes out of the cake clean.
While it's baking, make the glaze by putting a small thick bottomed pot onto the stove. Add the butter the sugar and pineapple juice and melt. Bring the mixture to the boil and simmer for 2-3 minutes.
Eventually the mixture will combine then clear and then reduce till it is bubbling profusely. It will be thick enough to coat the outside of the cake.
When the cake is turned put of the tin and it is hot, put it onto a rack with a tray underneath and start to spoon over the glaze. Use a pastry brush for best results to spread the glaze and cover every part of the cake that is visable. Cool. Serve with fruit or icecream
