Preheat the oven to 170ºC and butter and line a 7" round pan.
In a bowl, sift together Wheat flour, baking powder and baking soda.
Once the flour is sifted, whisk it with a wire whisk for few seconds to generate more air in the mixture.
Once mixed, add caster sugar in this flour mixture and mix again until well combined.
In an another bowl, mix together the wet ingredients, buttermilk, oil and vanilla. Mix properly until well combined.
Now make a well at the centre of your dry ingredients and slowly pour the wet ingredients into it.
Gently mix these together with a help of a spatula. Do not over mix and mix gently.
Pour the mixture in the prepared pan and bake for 45 -50 minutes or until toothpick inserted in the centre comes out clean.
Once out of the oven, let it cool on the wire rack for about 10-15 minutes and then de-mould it.
Cut the cake into desired sized slices and have it with a cup of hot tea.
If you want you can also frost this with your favourite frosting, or just sprinkle it with some cinnamon sugar or only powdered sugar before serving.
ENJOY!
