Serves:1 9 inch sponge cake
1 cup all purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
pinch of salt
4 tablespoons milk
1 cup butter at room temperature(leave it outside for atleast 4 hours needs to be soft when touched but not melted)
1 teaspoon vanilla extract

1 cup sugar

3.In a large bowl take the butter and sugar and beat vigorously, for about 5-6 minutes until pale color and fluffy texture is obtained. Add 1 egg yolk and beat, add the next and beat, continue until all are done .
4.Whisk the egg whites in a bowl until medium peaks form.
5.Now put aside the hand mixer and take a spatula for mixing, add flour little by little and fold it in(do not beat here-folding means you take the spatula cut the batter in the center and turn your wrist clockwise so that the batter from bottom comes up, this makes sure the air bubbles in the butter and sugar are not gone, otherwise cake will be soggy),if it starts to thicken add milk little by little until a smooth batter is obtained.
6.Fold in the egg whites.
