Sift flour and add baking soda and powder, then mix together and keep aside.

In a mixing bowl, put sugar and butter then mix, add eggs.

Pour butter milk. (check my red velvet recipe for buttermilk)

Mix again, then add the flour and mix again.

Add vanilla powder, mix.

Grease a baking pan of your choice. (put a little amount of butter in the pan, rub all over, then dust with little flour. The cake will come out nicely without sticking.)

Bake.
