Welcome to My City Food Secret:

How To Bake Soft & Moist Butter Cake. Soft & Moist Butter Cake. Butter cake is the first cake I learned when I started baking. I should say it's the easiest cake to make but just need a lot of patience in the mixing of the batter. It is unlike moist chocolate cake or sponge cake which can't be over mixed. Butter cake takes double or triple the time especially in the process of mixing the butter and sugar. We need to make it as light, soft and fluffy as possible so that the cake will not sink, as far as the butter weight is concerned. Overall it is still easy to make, just take a little longer than normal cakes. I hope you will give this a try :)

Ingredients:

250g (1 cup) unsalted butter (you will see the g on the packaging)
200g (1 cup) castor sugar (you can add another 20-30g or 2-3 tbsp more if you like it sweeter)
4 eggs
(1 1/2 cups) cake flour or all-purpose flour
1 tsp baking powder
1 tsp vanilla extract
1/4 tsp salt
