Might want to try using both baking powder and self raising flour - sieve both twice before use.
FOLD IN FLOUR GENTLY into butter-sugar mix.

Also this site might help you learn the physics in cake making http://www.exploratorium.edu/cooking/

125g butter, chopped
275g castor sugar
3 eggs
150g plain flour
75g self-raising flour
¼ tsp bicarbonate soda
½ cup milk

Grease 20cm round cake pan, cover base with baking paper. Cream the butter and sugar until light and fluffy. Gradually beat in the eggs. Add in the milk. Sift the flour, self-raising flour, bicarbonate soda and fold into the creamed mixture. Spread into prepared pan. Bake in 180° C for 45 minutes.

The cake is too sweet. The temperature could be too high. Maybe I should reduce the milk. I will adjust the recipe and see what happens. And thanks for the URL - very interesting site.

I’ve found that egg beating also affects the fluffiness of a cake. So mix them in well, and as you add more ingredients, be gentler with the batter to keep the tiny air pockets in the mix intact. (i read this in some book ages ago, dunno how true!). G’luck with the baking

If you want i can share my butter cake recipe with you.

Hope to hear from you.
